I. INTRODUCTION
1. By this action, we take necessary steps to implement the decisions of the World 
Radiocommunication Conferences held in 2007 and 2012.  Our decision consists of three components:  
1) a Report and Order that amends the Table of Frequency Allocations (Allocation Table) in 
Section 2.106 of the rules and a number of related service rules to implement certain radio frequency (RF) 
allocation decisions from the Final Acts of the World Radiocommunication Conference (Geneva, 2007) 
(WRC-07 Final Acts);
1
2) an Order that updates the International Table portion of the Commission’s 
Allocation Table to reflect the allocation decisions from the Final Acts of the World Radiocommunication 
Conference (Geneva, 2012) (WRC-12 Final Acts);
2
and 3) a Notice of Proposed Rulemaking that proposes 
to amend the Allocation Table and related service rules to implement certain RF allocation decisions from 
the WRC-12 Final Acts.  
II. EXECUTIVE SUMMARY
2. In the Report and Order (WRC-07 R&O), we implement allocation decisions from the 
WRC-07 Final Acts and make certain related updates to our service rules, including those for the Amateur 
Radio Service, Aviation Services, passive sensors, and maritime Automatic Identification Systems (AIS).  
Specifically, we:
• Allocate the 135.7-137.8 kHz band (2200 meter band) to the amateur service on a secondary
basis.
• Raise the secondary amateur service allocation in the 1900-2000 kHz band to primary status, 
while providing for continued use by commercial fishing vessels of radio buoys on the “open 
sea.”
3
• Allocate the 108-117.975 MHz and 960-1164 MHz bands to the aeronautical mobile (route) 
service (AM(R)S) on a primary basis for Federal and non-Federal use.
• Allocate the 5091-5150 MHz band to the aeronautical mobile service (AMS) on a primary 
basis for Federal and non-Federal use, limited to aeronautical mobile telemetry (AMT) for 
flight testing of aircraft and “Aeronautical Mobile Airport Communications System”
(AeroMACS) networks.
4
• Remove non-Federal AMT allocations from the 2310-2320 MHz and 2345-2360 MHz bands 
and an unused radionavigation service allocation from the 24.75-25.05 GHz band.

• Revise Part 87 of the Commission’s rules to update and correct the aviation services rules.
• Extend AIS capability by allocating the 161.9625-161.9875 MHz (AIS 1) and 
162.0125-162.0375 MHz (AIS 2) bands to the mobile-satellite service (MSS) (Earth-to-
space) and the aeronautical mobile (off-route) service (AM(OR)S) on a primary basis for 
Federal and non-Federal use.
• Protect passive sensors in the 1400-1427 MHz, 10.6-10.68 GHz, 23.6-24 GHz, 31.3-31.8 
GHz, 50.2-50.4 GHz, and 52.6-54.25 GHz bands from harmful interference by generally 
adopting WRC-07’s unwanted emissions levels for active services in six adjacent bands 
(1390-1395 MHz, 1427-1452 MHz, 22.55-23.55 GHz, 49.7-50.2 GHz, 50.4-50.9 GHz, and 
51.4-52.6 GHz) and its in-band sharing criteria for the 10.6-10.68 GHz and 36-37 GHz 
bands.
5
• Establish Federal coordination areas in California and Guam for non-Federal terrestrial 
operations in the 17.7-19.7 GHz range.
3. In the Order (WRC-12 Order), we update the International Table portion of the 
Commission’s Allocation Table to reflect the WRC-12 Final Acts.
6
4. In the Notice of Proposed Rulemaking (WRC-12 Notice), we propose to amend Parts 2, 
15, 80, 90, 97, and 101 of the Commission’s rules to implement allocation decisions from the WRC-12 
Final Acts and make certain updates to our rules.  Specifically, we propose to:
• Allocate the 8.3-11.3 kHz band to the meteorological aids service on a primary basis.
• Allocate the 472-479 kHz band (630 meter band) to the amateur service on a secondary basis.
• Amend the amateur service rules to provide for use of the 135.7-137.8 kHz (2200 meter) and 
472-479 kHz (630 meter) bands.  Amateur stations would share the band with power line 
carrier (PLC) systems operated by electric utilities.  Amateur stations would be permitted to 
operate in these bands at fixed locations when separated from electric transmission lines by a 
specified distance.
• Amend Part 80 of the Commission’s rules to authorize radio buoy operations in the 1900-
2000 kHz band under a ship station license.
• Limit the use of the 495-505 kHz band to the maritime mobile service.
• Allocate seven frequency bands (4.438-4.488 MHz, 5.25-5.275 MHz, 16.1-16.2 MHz, 
24.45-24.65 MHz, 26.2-26.42 MHz, 41.015-41.665 MHz, and 43.35-44 MHz) to the 
radiolocation service (RLS) on a primary basis for Federal and non-Federal use, allocate the 
13.45-13.55 MHz band to the RLS on a secondary basis for Federal and non-Federal use, 
limit the use of these RLS allocations to oceanographic radars, require that these radars not 
cause harmful interference to, or claim protection from, existing and future stations in the 
incumbent fixed and mobile services, and amend Part 90 of the Commission’s rules
accordingly.
• Reallocate the 156.7625-156.7875 MHz (AIS 3) and 156.8125-156.8375 MHz (AIS 4) bands 
to the MSS (Earth-to-space) on a primary basis for Federal and non-Federal use to allow for 
greater probability of vessel tracking, with resulting benefits to maritime safety and security.

A passive sensor is a measuring instrument in the Earth exploration-satellite service (EESS) or in the space 
research service (SRS) by means of which information is obtained by reception of radio waves of natural origin.

• Seek comment on the ability of Federal/non-Federal AMT stations to share spectrum with the 
incumbent services in the 4400-4940 MHz and 5925-6700 MHz bands.
• Extend the AM(R)S allocation from the 5091-5150 MHz band (adopted in the WRC-07 
R&O) by also allocating the 5000-5091 MHz range to the AM(R)S on a primary basis for 
Federal and non-Federal use.  AM(R)S use of the smaller 5000-5030 MHz range would 
extend the tuning range for AeroMACS, with the use of the 5010-5030 MHz band limited to 
those requirements that cannot be meet in the 5000-5010 MHz and 5091-5150 MHz bands.  
AM(R)S use of the 5030-5091 MHz band would support line-of-sight control links for 
unmanned aircraft.
• Allocate the 7850-7900 MHz band to the meteorological-satellite service (space-to-Earth) on 
a primary basis for Federal use.
• Allocate the 15.4-15.7 GHz band to the RLS on a primary basis for Federal use.
• Allocate the 22.55-23.15 GHz band to the space research service (SRS) (Earth-to-space) on a 
primary basis for Federal and non-Federal use and allocate the 25.5-27 GHz band to the SRS 
(space-to-Earth) on a primary basis for non-Federal use.
• Delete the aeronautical mobile service allocation from the 37-38 GHz band.
• Encourage operators of fixed stations operating in the 81-86 GHz and 92-94 GHz bands to 
take all reasonable steps to ensure that their unwanted emissions power in the 86-92 GHz 
band does not exceed the levels recommended by WRC-12.
III. BACKGROUND
A. Allocation Table
5. The Commission’s Allocation Table, contained in Section 2.106 of the rules, sets forth 
the allocation of radio frequencies both domestically and internationally.
7
  Except as otherwise provided 
for in Section 2.102 of the rules, the assignment, licensing and use of frequencies between 9 kHz and 
275 GHz must be in accordance with the Allocation Table in Section 2.106.  The Allocation Table is a 
formatted graphical table of six columns that are divided into cells, with each cell representing a specific 
frequency band (band).
8
The Allocation Table consists of three sections: 1) the International Table of 
Frequency Allocations (International Table),
9
which is subdivided into three Regional tables 
(columns 1-3);
10
2) the United States Table (U.S. Table), which is subdivided into the Federal Table of 
                                                     
7
An “allocation” is an entry in the Allocation Table of a given frequency band that designates its use by one or more 
terrestrial or space radiocommunication services or the radio astronomy service (together, “radio services”) under 
specified conditions. A “station” is one or more transmitters and/or receivers at one location for conducting radio 
communications. When a frequency band is allocated to one or more radio services on a primary basis, the 
Commission protects the authorized stations from interference based on the order in which the station license was 
issued unless it specifies a different protection arrangement. Stations of a secondary service may not cause harmful 
interference to, nor claim protection from, stations of a primary service to which frequencies are already assigned or 
may be assigned at a later date. 47 C.F.R. §§ 2.1(c), 2.104(d), 2.104(e)(2), 2.105(c).
8
A “band” is a continuous set of frequencies lying between two specified limiting frequencies.  See
Recommendation ITU-R V.662-3, “Terms and definitions,” at 14.  For the purpose of simplifying the discussion in 
this proceeding, we sometimes refer to multiple contiguous frequency bands as a “range.”  A “sub-band” (also 
referred to as a “segment,” particularly in amateur radio contexts) is a portion of a frequency band.
9
The International Table is described in 47 C.F.R. § 2.104.  The International Table currently reflects the “Table of 
Frequency Allocations” shown in Article 5, Section IV of the ITU Radio Regulations, Edition of 2008, except for 
certain corrections and updates.  47 C.F.R. § 2.100.  In the WRC-12 Order, infra, we update the International Table 
in Section 2.106 to generally reflect the ITU Radio Regulations, Edition of 2012.
10
For the allocation of radio frequencies, the ITU has divided the world into three Regions and has entered the 
allocations for these Regions in the International Table.  The United States and most of its insular areas are in 
(continued….)
Federal Communications Commission FCC 15-50
6
Frequency Allocations (Federal Table) (column 4) and the non-Federal Table of Frequency Allocations 
(non-Federal Table) (column 5);
11
and 3) a cross-reference to relevant FCC Rule Part(s) (column 6).
12
The frequency band referred to in each allocation is shown in the top left-hand corner of the cell(s) of 
each of these tables.
6. The International Table displays the allocations and international footnotes that have 
been adopted by the International Telecommunication Union (ITU).  The U.S. Table is the Commission’s 
means of organizing and presenting how the radio spectrum is used in the United States and its Region 2 
insular areas.  In the United States, radio spectrum may be allocated for either Federal or non-Federal use 
exclusively, or for Federal/non-Federal shared use.
13
Thus, the Federal Table component of the 
U.S. Table shows the frequencies used by the Federal government and administered by the National 
Telecommunications and Information Administration (NTIA), and the non-Federal Table component of 
the U.S. Table shows the frequencies used by all other entities and administered by the Commission.
14
All relevant footnotes are shown within the U.S. Table, and the text of these footnotes immediately 
follows the Allocation Table in Section 2.106.
15
The International Table, the Federal Table, and the 
FCC Rule Part(s) are included in the Allocation Table for informational purposes only.
16
B. World Radiocommunication Conferences
7. The ITU
17
allocates frequency bands to various radio services generally on either a 
worldwide or Regional basis and enters these radio services in its International Table as part of the 
(Continued from previous page)                                                           
ITU Region 2, which is generally North America and South America.  ITU Region 1 is generally Europe, Africa, the 
Middle East, the former Soviet Union, and Mongolia.  ITU Region 3 is the rest of Asia and Australasia.  See 
47 C.F.R. § 2.104(b) for the ITU’s official definitions and map of the Regions.
11
The U.S. Table is described in 47 C.F.R. § 2.105.
12
The FCC Rule Part(s) cross-references are described in 47 C.F.R. § 2.105(e).
13
47 C.F.R. § 2.105(b).
14
NTIA regulates and approves the use of spectrum by Federal departments and agencies and maintains the Federal 
Table in its Manual of Regulations and Procedures for Federal Radio Frequency Management (NTIA Manual).  
See Section 305(a) of the Communications Act of 1934, as amended, 47 U.S.C. 305.  The Commission regulates and 
approves the use of spectrum by non-Federal entities and maintains the non-Federal Table in Section 2.106.  See
Sections 303 and 305(a) of the Communications Act of 1934, as amended, 47 U.S.C. 303, 305(a); and 
47 C.F.R. §§ 2.102(a) and (b)(2), 2.105(a), 2.106.
15
Any footnote consisting of “5.” followed by one or more digits, e.g., 5.53, denotes an international footnote.  
Where an international footnote is applicable, without modification, to both Federal and non-Federal operations, the 
Commission places the footnote in both the Federal Table and the non-Federal Table and the international footnote 
is binding on both Federal users and non-Federal licensees.  If, however, an international footnote pertains to a 
service allocated only for Federal or non-Federal use, we place the international footnote only in the affected Table.  
Any footnote consisting of the letters “US” followed by one or more digits, e.g., US7, denotes a stipulation affecting 
both Federal and non-Federal operations.  U.S. footnotes appear in both the Federal and non-Federal Tables.  Any 
footnote consisting of the letter “G” followed by one or more digits, e.g., G2, denotes a stipulation applicable only to 
Federal operations. Federal footnotes appear solely in the Federal Table.  Any footnote consisting of the letters 
“NG” followed by one or more digits, e.g., NG2, denotes a stipulation applicable only to non-Federal operations.  
Non-Federal footnotes appear solely in the non-Federal Table.  In some cases, a letter, or letters, may be appended to 
the digit(s) of a footnote number to preserve the sequential order.  47 C.F.R §§ 2.105(d)(5), 2.106.
16
47 C.F.R. §§ 2.104(a), 2.105(d)(3) and (e).
17
When we refer to the ITU in this document, we are generally referring to ITU Radiocommunication Sector 
(ITU-R).  The work of ITU-R is organized and coordinated by the Director of the Radiocommunication Bureau 
(referred to as the “Bureau” in the ITU Radio Regulations, including the International Table).  Under its 
Constitution, the ITU shall effect allocation of bands of the RF spectrum, the allotment of radio frequencies and the 
registration of RF assignments…in order to avoid harmful interference between radio stations of different countries.  
WRCs shall normally be convened every three to four years…to consider specific radiocommunication matters.  See

Radio Regulations.
18
  The ITU revises its International Table and other provisions in its Radio 
Regulations at periodic World Radiocommunication Conferences (WRCs).
8. The ITU convened WRC-07 from October 22 to November 16, 2007, in Geneva, 
Switzerland, and adopted allocation changes that affect both Federal and non-Federal entities.
19
  The 
Commission initiated a proceeding to complete the domestic implementation of certain WRC-07 
allocation changes.
20
The Report and Order below addresses these WRC-07-related rule changes.
9. The Commission conducted its primary preparations for WRC-12 via its 2012 World 
Radiocommunication Conference Advisory Committee (WAC), which held eight public meetings 
between January 13, 2009, and April 19, 2011, to evaluate and approve recommendations and preliminary 
views that were later submitted for Commission consideration.
21
  The ITU held a Conference Preparatory 
Meeting (CPM) from February 14-25, 2011, to prepare and approve a report on the technical, operational, 
and regulatory/procedural matters relevant to the WRC-12 Agenda.
22
  In addition, the United States 
worked with other administrations to craft common proposals for Region 2 (North and South America).
23
By September 19, 2011, the Commission and NTIA had jointly transmitted their allocation proposals to 
the U.S. Department of State (U.S. Proposals for WRC-12).
24
10. The ITU convened the World Radiocommunication Conference 2012 (WRC-12) from 
January 23-February 17, 2012, in Geneva, Switzerland, and adopted allocation changes that affect both 
Federal and non-Federal entities.
25
  Subsequently, the ITU revised its Radio Regulations.

Amendment of Parts 1, 2, 15, 74, 78, 87, 90, and 97 of the Commission’s Rules Regarding Implementation of the 
Final Acts of the World Radiocommunication Conference (Geneva, 2007) (WRC-07), Other Allocation Issues, and 
Related Rule Updates, ET Docket No. 12-338, Notice of Proposed Rulemaking and Order, 27 FCC Rcd 14598 
(2012) (WRC-07 NPRM and Order).  In this item, we refer to the respective components of the WRC-07 NPRM and 
Order as the WRC-07 NPRM or the WRC-07 Order.

The WAC was chartered under the Federal Advisory Committee Act (FACA) to provide to the Commission with 
advice, technical support, and recommended proposals for WRC-12.  The Commission published the committee’s 
recommendations for public comment.  After consideration by the U.S. Government, many of the recommendations 
became a part of the U.S. views and draft proposals.  See http://www.fcc.gov/ib/wrc-12/.

initiating a new rulemaking proceeding to commence the domestic implementation of certain of the 
WRC-12 allocation changes.  Specifically, in the Order, below, we reflect the International Table as it is 
generally shown in the 2012 Edition of the ITU Radio Regulations in the Commission’s Allocation Table.  
In the companion WRC-12 Notice, below, we make proposals that implement the domestic allocation 
changes from the WRC-12 Final Acts.  In this action, we cite to various ITU-R Recommendations and 
Reports to which the ITU provides free online access.
27
  In addition, in Appendix A, we provide a 
glossary of frequently used radiocommunication service terms and we list the symbols for the 
ITU-defined frequency ranges that are used throughout this document.
IV. REPORT AND ORDER (WRC-07 R&O)
11. In this Report and Order, we amend Parts 1, 2, 25, 27, 74, 78, 80, 87, 90, 97, and 101 of 
the Commission’s rules to complete the implementation of certain allocation decisions from the WRC-07 
Final Acts.
28
As procedural background, several significant events followed the conclusion of WRC-07 in 
Geneva and the subsequent publication of its final acts.  First, on August 20, 2009, NTIA forwarded to 
the Commission (and subsequently updated on September 28, 2009; July 26, 2012; February 25, 2013;
March 4, 2014; and February 11, 2015) its recommendations for implementation of the WRC-07 Final 
Acts in the U.S. Table.
29
  The Commission adopted the WRC-07 Clean-up Order to update the 
International Table to reflect the WRC-07 allocation changes, as well as to make non-substantive editorial 
revisions to the Allocation Table and other rule sections.
30
  Subsequently, on November 15, 2012, the 
Commission adopted the WRC-07 NPRM, which contained a comprehensive set of proposals to update 
the allocations and certain related service rules for portions of the RF spectrum between 108 MHz and 
20.2 GHz.
31
We received 68 comments and 12 reply comments in response to the WRC-07 NPRM.

As part of our comprehensive review of the Allocation Table, we also make certain minor allocation changes that 
are not related to the WRC-07 Final Acts and make certain minor conforming changes to the Commission’s service 
rules, as further described below.

(NTIA WRC-07 Recommendations, pages 27-52 of the NTIA WRC-07 Recommendations, and pages 53-60 of the 
NTIA WRC-07 Recommendations).  Subsequently, NTIA corrected and supplemented its recommendations for 
WRC-07 domestic implementation.  See NTIA Letters, filed September 28, 2009 (NTIA WRC-07 Supplement);

Amendment of Parts 1, 2, 15, 25, 73, and 90 of the Commission’s Rules to Make Non-Substantive Editorial 
Revisions to the Table of Frequency Allocations and to Various Other Rules, Order,  25 FCC Rcd 9712 (OET, 
2010) (WRC-07 Table Clean-up Order).  Because the amendments to the Allocation Table in the WRC-07 Table 
Clean-up Order were limited to changes of a non-substantive, editorial nature, it was necessary for the 
Commission’s staff to create four U.S. footnotes (US226, US444, US444A, US519) to replicate the pre-WRC-07 
text of four international footnotes (RR 5.226, RR 5.444, RR 5.444A, RR 5.519).  WRC-07 Table Clean-up Order,

WRC-07 NPRM, 27 FCC Rcd 14598.  Because preparation of the WRC-07 NPRM necessitated a comprehensive 
review of the Allocation Table and related rules, the Commission’s proposals also included some allocation changes

discussing the various proposals, below, we use a different organizational approach from the WRC-07 
NPRM.  First, we evaluate those proposals that commenters discussed in their filings.  We then briefly 
address those proposals that generated no discussion in the record.
A. Amateur Service Use of LF and MF Bands
1. 2200 Meter Band (135.7-137.8 kHz)
12. In this section, we allocate the 135.7-137.8 kHz (2200 meter)
33
band to the amateur 
service on a secondary basis.  In accordance with an international requirement, we also limit amateur 
stations transmitting in the 2200 meter band to a maximum equivalent isotropically radiated power 
(EIRP) of 1 watt (W).
34
However, we defer consideration of operating parameters for the amateur service 
in this band to the WRC-12 Notice below. 
13. Background.  In the U.S. Table, the 130-160 kHz band is allocated to the fixed service 
(FS) and maritime mobile service (MMS) on a primary basis for Federal and non-Federal use.
35
WRC-07 
allocated the 135.7-137.8 kHz band to the amateur service on a secondary basis in all ITU Regions.  
WRC-07 also adopted RR 5.67A,
36
which restricts the use of this allocation to amateur stations 
transmitting with a maximum radiated power of 1 W (EIRP).
37
  There are no non-Federal stations in the 
FS and MMS that are licensed to operate in the 135.7-137.8 kHz band, and Federal use of this band is 
relatively light.
38
14. Footnote US2 explains that in the 9-490 kHz band, “electric utilities operate Power Line 
Carrier (PLC) systems
39
on power transmission lines for communications important to the reliability and 
(Continued from previous page)                                                           
we are accepting all late-filed submissions and waive the requirements of 47 C.F.R. § 1.415(d).  We provide a list of 
the parties in Appendix C.  
33
In the Amateur Radio Service, wavelength bands, rather than frequency bands are the usual means of identifying 
radio spectrum.  We note that wavelength (? in meters, m) is equal to the speed of light (c, which is taken to be 
3 x 10
8
m/s) divided by frequency (f in hertz, 1/s), e.g., ? = c/f = (3 x 10
8
m/s) / (136 x 10
3
1/s) ? 2200 m.  In this 
proceeding, we often use the term “2200 meter band” when referring to the 135.7-137.8 kHz band.
34
See n.37, infra.
35
The FS is a radiocommunication service between specified fixed points, and the MMS is a mobile service between 
coast stations and ship stations, or between ship stations, or between associated on-board communication stations; 
survival craft stations and emergency position-indicating radiobeacon stations may also participate in this service. 
47 C.F.R. § 2.1(c).
36
In the ITU Radio Regulations, a reference to international footnote 5.67A would be shown as “No. 5.67A,” which 
means provision No. 5.67A of Article 5.  Instead of using this abbreviation, to more clearly indicate that we are 
referring to an international footnote while still using a convenient shorthand, we will use the abbreviation for Radio 
Regulation (RR), i.e., “RR 5.67A.”
37
EIRP is the product of the power supplied to the antenna and the antenna gain in a given direction relative to an 
isotropic antenna (absolute or isotropic gain).  Effective radiated power (ERP) (in a given direction) is the product of 
the power supplied to the antenna and its gain relative to a half-wave dipole in a given direction.  We note that ERP 
is equal to EIRP divided by 1.64, e.g., 1 W EIRP = 0.61 W ERP.  See “Guidelines for Determining the Effective
Radiated Power (ERP) and Equivalent Isotropically Radiated Power (EIRP) of a RF Transmitting System,” Office 
of Engineering and Technology, FCC, Nov. 30, 2010 (available at 
https://apps.fcc.gov/oetcf/kdb/forms/FTSSearchResultPage.cfm?switch=P&id=47469).

A PLC system is an “unintentional radiator” used by an electric power utility entity on transmission lines for 
protective relaying, telemetry, etc., for general supervision of the power system.  An unintentional radiator is a
device that intentionally generates RF energy for use within the device, or that sends RF signals by conduction to 
associated equipment via connecting wiring, but which is not intended to emit RF energy by radiation or induction.  
47 C.F.R. §§ 15.3(t), (z).  PLC systems operate by the transmission of RF energy by conduction over the electric 
power transmission lines of the system.  PLC systems do not include those electric lines which connect the

security of electric service to the public. These PLC systems operate under the provisions of 47 CFR 
part 15, or Chapter 8 of the NTIA Manual, on an unprotected and non-interference basis with respect to 
authorized radio users.”
40
Under the Commission’s rules, a power utility operating a PLC system was
required to submit the details of all existing systems plus any proposed new PLC systems or changes to 
PLC existing systems to an “industry-operated entity.”
41
15. Previously, in ET Docket No. 02-98, the Commission declined to allocate the 
135.7-137.8 kHz band to the amateur service after finding a potential for interference between the 
proposed amateur radio and incumbent PLC operations.
42
  In 2009, James E. Whedbee (Whedbee) 
requested that the Commission allocate the 135.7-137.8 kHz band to the amateur service on a secondary 
basis and that the Commission amend Part 97 of its rules to provide for this use.
43
Prior to the 
WRC-07 NPRM, the Commission had not revisited its decision nor taken action on Whedbee’s petition 
for rulemaking.
16. Proposal.  In the WRC-07 NPRM, the Commission sought comment on whether the 
135.7-137.8 kHz band should be allocated to the amateur service on a secondary basis, with use limited, 
as specified in RR 5.67A, to amateur stations transmitting at a maximum EIRP of 1 W.
44
  Because PLC 
systems provide communications important to the reliability and security of electric service to the public, 
the Commission stated that it would consider adding an amateur service allocation to the 135.7-137.8 kHz 
band only if it were comfortable that amateur radio and utility PLC systems could successfully coexist in 
this band.
45
  It noted that the 2002 Amateur Radio NPRM recognized the potential for experimental 
amateur operations in the band and asked about subsequent developments that would inform a re-
evaluation of the decade-old decision.
46
  In particular, the Commission sought comment on technical rules 
or methods that could be implemented to assure such coexistence and, in particular, on the appropriate 
maximum field strength level and minimum separation distance from PLC systems for secondary amateur 
service operations in the band.
47
  The Commission further sought comment on whether requiring 
(Continued from previous page)                                                           
distribution substation to the customer or house wiring.  PLC systems “are subject only” to the requirements 
specified in Section 15.113.  47 C.F.R. § 15.113.  We note in particular that PLC systems operate within the 
9-490 kHz band “without a limit on the level of radiated emissions that leak from the power lines.”  Revision of Part 
15 of the Rules regarding operation of radio frequency devices without an individual license – USCG/FAA petition

47 C.F.R. §§ 2.106 footnote US2.  As background, we note that the Commission revised its rules in 1983 “to 
implement a new U.S. Footnote to provide enhanced recognition of [PLC] systems in the 10-490 kHz frequency 
band.  Rules establishing a notification procedure, an industry-operated entity to oversee the notification process, 
and a data base [were] also adopted so that band occupants can cooperate to the extent practicable to minimize or 
eliminate mutual interference.”  Amendment of Parts 2, 15, and 90 of the Commission’s Rules to provide 
recognition for power line carrier operations of electric utilities in the bands 10-490 kHz, Gen. Docket No. 82-9,

individual amateur stations in the 135.7-137.8 kHz band to be “quasi-coordinated” for fixed use at a 
specified location, an option that the Utilities Telecom Council (UTC) suggested in 2002, holds merit.
48
17. Comments.  The American Radio Relay League (ARRL) and 22 individual amateur 
service licensees submitted comments in support of allocating the 135.7-137.8 kHz band to the amateur
service on a secondary basis;
49
and UTC, the Edison Electric Institute (EEI), and nine electric utilities 
submitted comments opposing this allocation.
50
18. According to ARRL, the WRC-07 action provides good cause for the Commission to 
reevaluate its prior decision not to adopt an amateur service allocation.
51
  ARRL argues that the 2003 
Commission decision was not premised on a technical compatibility analysis but was instead based on an 
abstract concern by the utility industry for interference-free PLC operations.
52
  It states that the 
Commission “simply balanced the perceived importance of PLC systems against the acknowledged 
desirability of creating the first LF allocation for the amateur service, assuming that there was some 
interference potential.”
53
19. Amateur service commenters contend that interference will not occur to PLC systems 
from amateur operations.  For example, several amateur service commenters state that there have been no 
reports of interference to PLC systems from amateurs operating under experimental licenses
54
and others
report that experimental licensees transmit with an EIRP greater than 1 W at distances much nearer to 
PLC systems without interference problems arising.
55
  One amateur service commenter states that PLC

Id.  Had the Commission allocated the 135.7-137.8 kHz band to the amateur service on a secondary basis in 2003, 
UTC offered to conduct a “quasi-coordination” process to reduce the risk of interference to PLC systems.  Under the 
UTC suggestion, the Commission would have required that amateur operators submit data to UTC about their 
proposed operations.  UTC would then notify utilities about those amateur operations that may impact their PLC 
systems.  Utilities and amateur operators would cooperate to avoid causing interference to each other’s operations.

Submission” (March 28, 2013)  at 1, and Wasson Reply Comments at 1.  Wasson also states that an allocation would 
consolidate LF experimentation and therefore “the potential for interference is greatly reduced and the task of 
identifying the source of interference is made easier.”  See Wasson Reply Comments at 2.

systems operate at noise levels several orders of magnitude greater than the magnitude of amateur 
signals.
56
ARRL contends, in particular, that there is no risk of interference between amateur stations and 
PLC operations when they are separated by one kilometer (km).
57
20. By contrast, UTC and EEI assert that nothing has changed since 2003 to cause the 
Commission to alter its decision not to allocate the band for the amateur service.
58
UTC and EEI state
that in 2003 the “Commission provided extensive technical analysis” to support the decision not to make 
an amateur service allocation in the band and that for the same reasons the Commission should again 
decline to adopt this allocation.
59
  Furthermore, UTC argues that there is no practical coexistence 
mechanism to enable sharing between amateurs and PLC.
60
It states that amateur radio operations are 
unpredictable and uncoordinated and power limits by themselves would not protect PLC systems.  UTC 
reiterates its comments from 2003 that antenna height limits and other technical restrictions must also be 
established to mitigate interference.
61
  In addition, Entergy Services, Inc. states that unlike other licensed 
facilities such as navigation beacons, procedures to prevent interference between PLC systems and 
amateur stations will not be possible “because amateur radio operators using the reallocated spectrum 
may not necessarily operate at a permanent, fixed location, making it difficult for utilities with PLC 
systems to ascertain if an interference condition may exist that it needs to address.”
62
21. A number of utilities emphasize the high cost of moving or modifying PLC systems to 
avoid interference from amateur stations.
63
  In addition, UTC and several utilities also express concern 
that amateurs would use their status under the proposed allocation to force utilities (which operate on an 
unlicensed basis) out of the band.
64
  According to the Dayton Power and Light Company, the fact that this 
secondary allocation has been made in other countries is irrelevant because “[u]tilities in those countries 
may not be using the same frequencies for their control equipment.”

56
See Bunn Reply Comments at 1.  One amateur points out that a Wisconsin utility bordering Canada has not 
experienced “dire” consequences even though Canada has allocated the 135.7-137.8 kHz band to the amateur radio 
service. See Whedbee Reply Comments to Exelon Corp. et. al. filed on Feb. 15, 2013 at 1-2.  Considering that 
Canada is separated from Wisconsin by Lake Superior, we do not find this fact particularly relevant.
57
ARRL Reply Comments at 4 and Annex A.  In support of its assertion that there is no potential for interference 
from amateur stations transmitting with a maximum EIRP of 1 W to PLC systems at separation distances greater 
than 1 km from a transmission line carrying the PLC signals, ARRL’s submitted a technical analysis that draws on a 
1985 NTIA technical report which considered the potential interference from fixed stations to PLC systems in the 
150-190 kHz band.  See Andrew Farrar, Herb Dobson, Fred Wentland, Evaluation Techniques – Fixed Service 
Systems to Power-Line-Carrier Circuits, Report TR-85-181, U.S. Department of Commerce, Sept. 1985, at p. 5-77

Utilities estimate the cost of changing the PLC frequency on one transmission line to be between $10,000 and

Electric, LLC estimates the cost of replacing its 60 existing PLC systems at $9.6 million while GRE estimates the 
cost of replacing its 10 PLC systems with fiber-optic systems at $18-36 million.  CenterPoint Energy Comments at 2

22. Decision.  In the WRC-07 NPRM we stated that we would add an amateur radio 
allocation to the 135.7-137.8 kHz band only if we were comfortable that amateur stations and PLC 
systems could coexist.  We conclude that such sharing of the band is possible.  Since the Commission last 
considered this issue, amateurs have successfully operated in the band under experimental licenses 
without reported PLC interference.  We are also encouraged by the fact that numerous fixed 
radionavigation beacons, which operate at much higher powers, share spectrum with PLC systems 
without reported interference.
66
  As discussed below, the exact scope of acceptable amateur operations in 
the band is a matter that warrants further examination.
23. We are unconvinced by the claims of UTC and electric utility commenters that 
coexistence of amateur stations and PLC systems is not possible.  These claims largely rest on the 
assumption that amateur stations in the band would operate under the rules applicable to other amateur 
bands which, in general, permit mobile operations and operations at high power and with any type of 
antenna.  It is clear that we will have to establish appropriate requirements for amateur use of the band if 
we are to ensure compatibility with PLC systems.  Such requirements will likely include limiting amateur 
operation to fixed locations that are suitably distant from the transmission lines upon which PLC systems 
operate, as well as the imposition of power limits and other technical rules to govern amateur operation.  
The existing record offers useful comments in this regard.  For example, American Electric Power 
Company (AEP), while opposed to the proposed allocation, also acknowledges that amateur radio 
operations would likely have to “include an extremely large antenna or [be in] very close proximity to a 
transmission line” to raise interference concerns.
67
Amateur radio commenter Davis agrees with UTC’s 
statement that the Commission’s suggestion in the WRC-07 NPRM to limit antenna height “would help to 
provide some basis upon which to further develop a coexistence mechanism for fixed amateur radio 
operations, but not for mobile.”
68
24. We reach our decision because there are tangible benefits in providing for licensed 
amateur use in the 135.7-137.8 kHz band.  Besides promoting harmonization with relevant WRC-07 
decisions, the addition of a secondary amateur allocation will provide amateur operators with new 
opportunities for experimentation with equipment, techniques, antennas, and propagation phenomena in a 
frequency range that is significantly different from all other bands allocated for this service.
69
  However, 
given that the band is of interest to the amateur community for its experimentation potential in contrast to 
the routine and widespread communication activities among users that are common characteristics of 
other amateur bands, we can also expect that the amateur interest in the band will continue to be limited 
and specialized.

as “critical facilities of national importance.”  See DP&L Comments at 2.  Cf. UTC Comments at 7 (PLC systems in 
Europe use the band only for in home applications where the risk of interference is less than in the U.S.).
66
In the 9-490 kHz range, there are 578 Federal assignments for the radio beacon stations (station class ALB) in the 
aeronautical radionavigation service (ARNS).  We note however that the assigned frequencies for ALB stations 
actually extend only from 191 to 429 kHz, and that the output power of these stations range from 10 W to 4 kW.  
This study was conducted using the Government Master File (GMF) for March 7, 2015.
67
AEP Comments at 1-2.  AEP is opposed to the proposed allocation largely on the basis that its PLC signals could 
become an unlicensed interference source to licensed Amateur Radio users, and AEP would have to disable its 
systems to comply with FCC regulations regarding harmful interference.

of ambient noise which, in turn, will contribute to the radio art).  See also Andrews Comments at 1-2, Duncan 
Comments at 1, Leggett Comments at 3-4, and Peak Comments at 1-2.

25. We also recognize the importance of PLC systems operating under Section 15.113 of our 
rules.  UTC and the utilities emphasize the continued importance of PLC systems to the reliability of 
electric service.
70
  AEP states that PLC systems are used extensively because they are a cost-effective 
component of a power system protection scheme.
71
  According to UTC there are now almost 2,100 PLC 
transmitters operating in this frequency band.
72
  Great River Energy (GRE) states that interference from 
amateur stations could potentially cause protective relaying equipment to fail to operate which could 
result in damage to transformers and other equipment that cost millions of dollars in addition to causing 
outages to thousands of people.
73
NextEra Energy, Inc. (NextEra) states that it and other utilities are in 
fact being required to use more of the band to help ensure the reliability and security of electric service to 
the public.
74
American Transmission Company LLC claims that reallocation would require it and other 
electric utilities to abandon a large swath of already-crowded PLC spectrum for which there is no 
practical, cost- or time-effective substitute.
75
26. The amateur community has made it clear that it has no intent to diminish or supplant 
PLC operations.
76
  Accordingly, we are taking a measured and deliberate approach to the introduction of 
licensed amateur operations into the band.  The secondary amateur allocation we adopt does not by itself 
convey authority to amateur licensees to operate in the band.  Rather, we defer consideration of the 
appropriate amateur rules for operation in the band to the accompanying WRC-12 Notice.  Amateur use 
will be governed by any future service rules that specify when, how, and under what conditions we will 
permit amateur use of the 135.7-137.8 kHz band.
77
  We intend to structure these service rules to promote 
shared use of the band among amateurs and PLC systems.
78
  Amateurs will not be able to use their 
allocation status to force unlicensed PLC operations out of the band, and utilities will have no cause to 
abandon or incur large costs to modify existing PLC systems.
27. Taking steps to enhance efficient, shared use of our scarce spectrum resource both serves 
the public interest and promotes fundamental Commission spectrum management goals.  We recognize 
the relative public benefits of PLC and amateur radio, and we explicitly reject the suggestion that we must 
choose one to the exclusion of the other.  Our objective is to allocate spectrum on a secondary basis to 
amateur stations in a manner that is compatible with existing PLC systems.  However, we also expect to 
permit amateur operators to make use of the allocation in a manner that is less burdensome and more 
productive than they are currently afforded under the experimental authorization process.

“Amateur Radio operators have a long history of successful sharing with Part 15 devices in other bands.  Never 
has the Amateur Service attempted to oust an unlicensed user from an Amateur allocation due to interference 
concerns.”  ARRL Reply at 7.
77
Until service rules are adopted, amateur operators may continue to apply under the Commission’s experimental 
licensing program to use the 135.7-137.8 kHz band.  
78
See discussion of proposed service rules, paras. 167-180, supra.
79
If, after consideration of the record, we conclude that a method to permit the operation of existing PLC systems is 
not readily achievable, we will defer the adoption of service rules and amateur users will have to continue to use the 
experimental licensing process to operate in the band.
Federal Communications Commission FCC 15-50

28. In making this secondary amateur service allocation, we acknowledge that we are 
following a different path than the Commission did in its 2003 Amateur Radio R&O.  However, our 
decision today both recognizes and builds on the foundation the Commission laid in its 2003 Amateur 
Radio R&O.  The 2003 Amateur Radio R&O implicitly assumed that amateur stations would not operate
at fixed locations.  The service rules we propose today include appropriate limitations, such as restricting
amateur stations to fixed locations suitably distant from PLC operations, that we believe will permit 
shared use of the band.
80
  Moreover, the spectrum management landscape has changed since 2003.  The 
Commission has adopted spectrum sharing arrangements in a number of other bands, which makes us 
confident that a coexistence arrangement between amateur stations and PLC systems is possible.
81
Advancements in geographic information system (GIS) technologies and mapping capabilities provide 
further assurances that mechanisms exist for maintaining sufficient distances between amateur sites and 
the transmission lines used by PLC systems.
29. For these reasons, we conclude that it is in the public interest to add a secondary amateur 
service allocation to the non-Federal Table in the 135.7-137.8 kHz band.  In accordance with the WRC-07 
Final Acts, we also restrict use of this secondary amateur service allocation to amateur stations 
transmitting a maximum EIRP of 1 W by adding a reference to RR 5.67A to the U.S Table for this band.
2. Raising the Amateur Service in the 1900-2000 kHz Band to Primary Status
30. In this section, we adopt the Commission’s proposal to raise the secondary amateur 
service allocation in the 1900-2000 kHz band to primary status.
82
  We also delete the primary 
radiolocation service (RLS) allocation within the United States.  However, to support spectrum use by the 
U.S. commercial fishing fleet that was identified in the record, we maintain a limited RLS allocation to 
support radio buoy operation on the open sea in the 1900-2000 kHz band.
31. Background. Currently, the amateur “160 meter” band consists of two frequency bands: 
the 1800-1900 kHz band, which is allocated solely to the amateur service on a primary basis, and the 
1900-2000 kHz band, which is allocated to the RLS on a primary basis for Federal and non-Federal use 
and to the amateur service on a secondary basis under the terms of footnote US290.
83
  Historically, the 
larger 1715-2000 kHz band was allocated exclusively for amateur radio use, but subsequently the size of 
this allocation was reduced and its use was severely limited.
84
  By 1983, the Commission had adopted the 
current allocations for the 1800-1900 kHz and 1900-2000 kHz bands.
85
  The last station license that 
authorized the use of the non-Federal RLS allocation in the 1900-2000 kHz band expired in 2004.

On March 31, 2015, Commission staff conducted a review of the 1900-2000 kHz band using the Commission’s 
Universal Licensing System (ULS) database and found no active call signs.

16
current Federal use of the 1900-2000 kHz band is relatively light, with only 10 assignments that authorize 
operations in this band.
87
32. Proposal.  In the WRC-07 NPRM, the Commission proposed to amend the U.S. Table to 
remove the Federal and non-Federal RLS allocations from the 1900-2000 kHz band and to raise the 
secondary amateur service allocation to primary status because there appear to be few (if any) RLS 
stations operating in this band.
88
  It requested comment on the status of Federal RLS stations that are 
authorized to operate in the San Diego area, and the extent to which NTIA would need us to recognize 
these stations as grandfathered Federal users.  The Commission also anticipated that the other relatively 
low-power Federal assignments would continue to operate on an unprotected and non-interference basis.  
Consequently, the Commission proposed to delete footnote US290 from the list of U.S. footnotes and 
delete the 1900-2000 kHz band and several limitations that pertain only to that band from the 
Radiolocation Service Frequency Table in Section 90.103(b) of the Commission’s rules.  It also proposed 
to amend Section 97.303 of our rules by revising paragraph (c) to remove the 1900-2000 kHz segment 
from the list of frequency segments that are allocated to the RLS in the United States and other nations, 
and by revising paragraph (g) to list, by ITU Region, where amateur stations transmitting in the 160 meter 
band must not cause harmful interference to, and must accept interference from, stations authorized by 
other nations.  The Commission concluded that these actions would update the Commission’s rules to 
reflect actual use and – after more than half a century – restore this 100 kilohertz of spectrum to nearly 
exclusive amateur radio use.
33. Comments. We received comments from the ARRL and 43 individual amateur service 
licensees in support of the Commission’s proposal.
89
  An additional commenter, ITM Marine (ITM), 
requests that we “keep this band available for radio location devices,” citing extensive use by radio 
buoys.
90
  ARRL states that it is timely to restore to the amateur service access to the entire 1800-2000 kHz 
band on a primary basis.  It notes that the 1900-2000 kHz band was only available for re-accommodation 
of displaced licensees from the 1605-1705 kHz band, but that the use of technology with inherently 
greater reliability and general spectrum efficiency advancements mean that relocations into the band are 
                                                     
87
One Federal assignment authorizes land and mobile stations in the RLS to transmit on 1922 kHz using a necessary 
bandwidth of 600 Hertz within a protected radius of 193 km centered on San Diego, California.  All other Federal 
assignments in the 1900-2000 kHz band are for unallocated uses and thus these assignments operate on an 
unprotected and non-interference basis.  See WRC-07 NPRM, 27 FCC Rcd at 14609, para. 23.

no longer necessary.
91
ARRL also requests that we simply delete the entire text of the current 
Section 97.303(g) because this rule section would no longer applicable.
92
34. Amateur radio commenters endorse our observation that there is little or no non-Federal 
RLS activity in the band.  For example, several commenters state that RLS signals in the 1900-2000 kHz 
band are not receivable at their locations.
93
  Others agree that radiolocation beacons in the 1705-2000 kHz 
range have fallen out of use.
94
A number of commenters state that both the 1705-1800 kHz and 
1900-2000 kHz segments “appear devoid of radiolocation beacons, except for a few weak signals 
reportedly from low-power radio buoys used on the high seas by commercial fishermen.”
95
35. Amateur radio commenters describe numerous ways in which the allocation would be 
beneficial to the amateur service.  ARRL, in particular, notes that the 1800-2000 kHz band is capable of 
and is used for worldwide skywave and groundwave communications; that this band is exceptionally 
heavily used, especially during protracted sunspot minima; and that it is at present the only MF amateur 
radio allocation.
96
36. Individual amateur radio commenters further describe how the 1900-2000 kHz band is 
particularly useful to the amateur operators.  For example, four commenters state that because the 
1800-2000 kHz band is the only MF allocation presently available to amateurs, propagation
characteristics and other properties of 160 meter band make it uniquely interesting, and during periods of 
low solar activity, this is often the only amateur band available for night time communications over 
distances up to 500 miles.
97
Numerous commenters state that decreased sunspot activity will greatly 
impact HF communication in the future, and that the 160 meter band could become more important for 
both long and short range reliable communications.
98
Three commenters state that there has been 
increasing use of the band, due to experimentation and changes in propagation,
99
and another commenter 
states that he and his colleagues find this MF band to be of intense interest, especially relating to the study 
of radio wave propagation.

The WRC-07 NPRM proposed to revise Section 97.303(g).  ARRL notes that Section 97.303 contains the general

other paragraphs refer to the specific sharing requirements of secondary amateur service allocations.  See ARRL

These commenters also state that the 2 MHz range lends itself particularly well to certain forms of technical 
investigation and self-instruction in the radio art.  For example, in the realm of antennas, amateur experimentation 
could lead to the development or improvement of efficient, physically low profile medium-wave transmitting 
antennas, anti-skywave transmitting antennas that provide local ground wave coverage while generating minimal 
interference at distant points, as well as effective noise cancelling and weak-signal receiving antennas.  See Chester

160 meter band, one commenter asserts that significantly more amateur stations are operating on these 
frequencies than just a few short years ago.
101
37. In addition, several commenters state that amateur operators use the 1900-2000 kHz band 
for valuable emergency services.
102
Commenters further suggest that a primary allocation status would 
provide a measure of certainty for amateur operators, who must decide whether to invest the time and 
money to install an antenna of sufficiently large size to effectively communicate in the band.  For 
example, four commenters note that, while the virtual disappearance of RLS beacons from the 
1900-2000 kHz band gives amateurs unfettered use of the 1900-2000 kHz segment, the secondary status 
of the amateur service nevertheless leaves users vulnerable to future RLS interests that can easily be 
accommodated elsewhere.
103
38. In its comments, ITM states that it is an importer/distributor of radiolocation devices that 
are commonly known as radio buoys, that these devices are “licensed” for use in the 1900-2000 kHz 
band, and that these devices have been used for 30-40 years by the U.S.-based “high seas migratory 
species fishing fleets” in the Atlantic and Pacific Oceans.
104
  ITM estimates that there are at least 
500 active vessels, and possibly 250-500 additional vessels in the United States, which use these radio 
buoys, and that each of these vessels carry up to 10 or more radio buoys.  ITM states that the buoys assist  
fishermen in locating their gear and provide an important safety factor if the gear needs to be retrieved 
quickly to escape bad weather, and that fishing operations have been developed around the use of the 
buoys.
105
  With regard to the lack of licenses issued for operation in the 1900-2000 kHz band, ITM states 
that since this equipment is “primarily used offshore, in international waters,” the operators did not 
license them for use in the USA (they are FCC approved) and that the owners already have licenses for 
the vessels’ “transmitting equipment,” and believe that the buoys fall under this license as “ships
equipment.”
106
  ITM requests that the Commission “keep this frequency band available for radiolocation 
devices,” and that, if possible, the Commission expand the band, because its customers have complained 
that it is getting crowded.
107
39. In its reply comments, ARRL states that the buoys are illegal transmitters, regardless of 
where they are deployed, since there is no marine allocation in this band and no Part 80 ship license 
permits radiolocation in any portion of the 1900-2000 kHz band.
108
  It also states that no United 
States-registered vessel may operate Part 90 equipment on any frequency for radiolocation without a

license from the Commission, and that operation pursuant to Section 90.103 of the Commission’s rules in 
the 1900-1950 kHz and/or 1950-2000 kHz segments clearly necessitates a license.
109
40. Decision.  We allocate the 1900-2000 kHz band to the amateur service on a primary 
basis, and as described below, remove the primary RLS allocation from the U.S. Table.  This action 
supports the increased spectrum use of the 160 meter band reported by commenters and provides 
spectrum support for the emergency communications that the amateur radio community provides.  This 
action also provides the amateur service with the long-term security that primary status entails, to the 
benefit of those licensees who seek to operate in the 160 meter band.  NTIA has not informed us of any 
Federal RLS requirements in the 1900-2000 kHz band, and thus we take no additional action in this 
regard.
41. Although we had anticipated that there was no non-Federal RLS use of the 
1900-2000 kHz band, the record indicates that there are maritime users, including the U.S. “high seas”
migratory species fishing fleet, which make use of radio buoys in both the Atlantic and Pacific oceans as 
well as within 200 nautical miles of the coastline.
110
  We did not identify these users in the 
WRC-07 NPRM because they did not appear in our licensing database.  The Commission’s Part 90 rules 
allow any person engaged in commercial activity to obtain a license to use the 1900-2000 kHz band for 
radiolocation.
111
  ITM holds a Grant of Equipment Authorization issued under the authority of the 
Commission to sell “radio buoys” that operate in the 1900-1999 kHz band pursuant to our Part 90 rules.
112
  
Apparently, fishing vessels have operated radio buoys in U.S. waters under the belief that a ship station 
license issued under Part 80 of our rules allows operation of the buoys.  However, a Part 80 license only 
                                                     
109
ARRL claims that amateur radio operators have suffered interference in the 1900-2000 kHz band from these 
buoys.  It also asks us to launch an investigation of this company, and says that our WRC decision should instruct 
“fishing vessels using these devices without appropriate licenses to cease using them unless and until a license is 
obtained, and compliance with Section 90.101 et seq. is achieved.”  Id.

The terms and definitions in 33 C.F.R. Part 2, Subpart B provide a useful context for our discussions 
herein: Except for certain enumerated purposes, “high seas” means all waters that are not the exclusive economic 
zone, territorial sea, or internal (i.e., inland) waters of the United States or any other nation. The exclusive economic 
zone generally extends from 12 to 200 nautical miles from the territorial sea baseline (which is comprised of the low 
water line on National Oceanic and Atmospheric Administration (NOAA) charts plus closing lines across 
legally-defined bays and rivers). 33 C.F.R. §§ 2.20, 2.22(a)(1), 2.24(a), 2.26, 2.30(b), 2.32(d). See also 
http://www.gc.noaa.gov/gcil_maritime.html (for NOAA’s description of maritime zones and boundaries) and 
Presidential Proclamation No. 5928, December 27, 1988 (which extended the territorial sea from 3 to 12 nautical 
miles; available at http://www.gc.noaa.gov/documents/terr_sea_54_fr_777.pdf).  As of March 31, 2015, public 
documents report that 367 fishing vessels are authorized by the U.S. to be used for fishing on the high seas. See

Specifically, FCC Identifier XLTKTUS-IL authorizes ITM to import and/or market equipment of the class 
“Licensed Non-Broadcast Station Transmitter” that is specifically identified in the Notes as a “RADIO BUOY,” 
which operates in the “1.9-1.999” MHz frequency range under “FCC Rule Part[] 90” using 8.0 W of conducted 
power, a frequency tolerance of 5.0 parts per million, and emission designator 60HA1A (i.e., 60 hertz of necessary 
bandwidth, double-sideband carrier, single channel, telegraphy for aural reception).  The name of the grantee is 
listed as “International Technical Mktg Inc;” however, the listed address and the attention line (“Steve Beaver, 
President”) are consistent with the ITM Comments.  See FCC Identifier XLTKTUS-1L.  We note that at least two 
other companies have been issued equipment authorizations for a licensed non-broadcast station transmitter under 
Part 90 of our rules that appear to be offered for sale as radio buoys: 1) Ryokuseisha Corporation with 5 W of output 
power in the 1.606-2.85 MHz range (see FCC Identifier EC26EISV-L3); and 2) Taiyo Musen Co Ltd with 6 W of 
output power (emission 750HA1A) in the 1.706-1.8 MHz and 1.9-2 MHz ranges (FCC Identifiers 
BAA9JKTB-548WL and BAA9JKTB-548WH).
Federal Communications Commission FCC 15-50

applies to stations in the maritime services and does not permit operation of radio stations that require a 
Part 90 license such as the radio buoys at issue here.
113
42. For purposes of updating and revising the Allocation Table, we find that we should take 
account of radio buoy use on the open sea by continuing to provide for a significantly restricted use of the 
current RLS allocation in the 1900-2000 kHz band.  Specifically, we remove the primary RLS allocation 
from the U.S. Table and add new footnote NG92 to the Allocation Table, which provides for radio buoy 
operations in the 1900-2000 kHz band on a primary basis in Region 2 and on a secondary basis in 
Region 3 (which is consistent with the existing primary/secondary Regional distinction for RLS), limited 
to operations on the open sea.
114
In addition, we amend the Radiolocation Service Frequency Table in 
Section 90.103(b) of our rules by removing the 1900-2000 kHz band.
115
  By doing so, we provide the 
amateur service with primary and exclusive use of the 1900-2000 kHz band on the land territory of the 
United States and its insular areas.  Further, we implement our proposal to remove the 1900-2000 kHz 
segment from Section 97.303(c), and consistent with ARRL’s comments, to remove Section 97.303(g) in 
its entirety from our rules.
116
43. We nevertheless recognize the public benefit associated with the use of radio buoys by 
the U.S. commercial fishing fleet.  In the companion WRC-12 Notice, we propose revisions to the 
Commission’s rules that would provide radio buoy operators a legitimate path to operate.
117
  In the 
meantime, we adopt a waiver, on our own motion, of Sections 80.375 and 90.103 of our rules to allow 
operation of Commission-approved 1900-2000 kHz radio buoys on the open sea by commercial fishing 
vessels that have a valid ship station license under Section 80.13 of our rules.
118
  We conclude that grant 
of this waiver is in the public interest.  Use of these radio buoys allows such commercial fishing vessels 
to locate their fishing lines and nets more quickly, which saves them fuel and time and reduces the 
likelihood that fishing lines and nets will be lost.  Given that the radio buoys appear to use low power and 
narrow bandwidths, we believe that they can be accommodated with minimal impact on amateur users.
119
  
Based on the information we have received from ITM, we have structured the waiver to authorize 
offshore radio buoy use by commercial fishing vessels.  If, contrary to what this record suggests, there are 
commercial fishermen currently using radio buoys on the Great Lakes or inland waters, those fishermen
may request waivers regarding their current operations.  Lastly, we grant this waiver pending the outcome 
                                                     
113
“One ship station license will be granted for operation of all maritime services transmitting equipment on board a 
vessel.”  47 C.F.R. § 80.13(b).  Section 80.13(c) allows certain ship stations to be licensed by rule.  47 C.F.R. 
§ 80.13(c).  In either case, the Part 80 license does not apply to Part 90 services.
114
See Appendix D for the text of footnote NG92.
115
As of March 31, 2015, there were no active status call signs listed in the Commission’s Universal Licensing 
System (ULS) for the 1900-2000 kHz band.
116
While radio beacons will operate on a primary basis on the open sea within ITU Region 2, we believe that it is 
unnecessary and potentially confusing to highlight this low-power, uncoordinated use in Section 97.303 of our rules.
117
See WRC-12 Notice, Section VI.A.2, “Radio Buoys Operating in the 1900-2000 kHz Bands,” paras. 153-158, 
infra.
118
See 47 C.F.R. § 1.3.  This waiver will apply to commercial fishing vessels with a ship station license issued under 
Section 83.13(b) and those that are licensed by rule under Section 83.13(c).  47 C.F.R. § 80.13.  This is a limited 
waiver.  It does not apply to vessels other than commercial fishing vessels and does not authorize the use of these 
buoys in other locations, such as on the Great Lakes.  The open sea is the water area of the open coast seaward of the 
ordinary low-water mark, or seaward of inland waters.  47 C.F.R. § 80.5.  “Inland waters” means the waters 
shoreward of the territorial sea baseline.  33 C.F.R. § 2.26.
119
Our actions largely accomplish our proposal to remove the RLS allocation from the band.  Additionally, and as 
discussed in the WRC-12 Notice, we request comment on methods to minimize any interference potential associated 
with radio buoy use.
Federal Communications Commission FCC 15-50
21
of the WRC-12 Notice, and without prejudice to enforcement regarding prior unauthorized radio buoy 
operations.
44. Finally, in their comments, Todd Carpenter and Ken Reid suggest that since few, if any, 
signals of any type are heard in the 2000-3300 kHz range, secondary amateur band privileges could be 
authorized in this band.
120
Whedbee requests that we permit the amateur service to operate in the 
spectrum below 9 kHz on an unallocated basis.
121
These issues fall outside the scope of the 
WRC-07 NPRM and raise new technical and policy considerations.  We therefore decline to address these 
comments in this proceeding.
B. Aviation Services Use of VHF, UHF, and SHF Bands
1. Aeronautical Mobile (R) Service Allocation in the 108-117.975 MHz Band
45. Background.  In the U.S. Table, the 108-117.975 MHz band is allocated to the 
aeronautical radionavigation service (ARNS) on a primary basis for Federal and non-Federal use.
122
Two 
ARNS systems operate in this band: the VHF Omnidirectional Range (VOR) system and the Instrument 
Landing System (ILS).
123
46. The 2003 World Radiocommunication Conference (WRC-03) adopted RR 5.197A, 
which provided a limited aeronautical mobile (route) service (AM(R)S) allocation in the 
108-117.975 MHz band to support air navigation and surveillance functions.
124
The Commission did not 
implement this international footnote domestically.  WRC-07 modified RR 5.197A to remove the 
limitation to only air navigation and surveillance functions.  In addition, WRC-07 revised RR 5.197A to 
state that the 108-117.975 MHz band is allocated to the AM(R)S on a primary basis, limited to systems 
operating in accordance with recognized international aeronautical standards, that such use must be in 
accordance with Resolution 413,
125
and that AM(R)S use of the 108-112 MHz sub-band is limited to 
                                                     
120

121
See Request of Whedbee, titled “Informal Request and Comments, In Re: Allocation Display Changes,” 
(Nov. 26, 2012) at 1-3.
122
The ARNS is a radionavigation service intended for the benefit and safe operation of aircraft.  47 C.F.R. § 2.1(c).
123
Footnote US93 states that the frequency 108 MHz may be authorized for use by VOR test facilities, subject to the 
condition that no interference is caused to the reception of frequency modulation (FM) broadcasting stations.
124
The AM(R)S is an aeronautical mobile service (AMS) reserved for communications relating to safety and 
regularity of flight, primarily along national or international civil air routes.  AMS is a mobile service between 
aeronautical stations and aircraft stations, or between aircraft stations.  An aeronautical station is defined as a land 
station in the AMS.  An aircraft station is defined as a mobile station in the aeronautical mobile service, other than a 
survival craft station, located on board an aircraft.  47 C.F.R. § 2.1(c).
125
WRC-07 revised Resolution 413 to resolve: (1) that any AM(R)S systems operating in the 108-117.975 MHz 
band shall not cause harmful interference to, nor claim protection from ARNS systems operating in accordance with 
international aeronautical standards; (2) that any AM(R)S systems planned to operate in the 108-117.975 MHz band 
shall, as a minimum, meet the FM broadcasting immunity requirements contained in Annex 10 to the ICAO 
Convention on International Civil Aviation for existing ARNS systems operating in this frequency band; (3) that 
AM(R)S systems operating in the 108-117.975 MHz band shall place no additional constraints on the broadcasting 
service or cause harmful interference to stations operating in the bands allocated to the broadcasting service in the 
87-108 MHz band and Radio Regulation No. 5.43 does not apply to “ICAO standard ground-based systems for the 
transmission of radionavigation-satellite differential correction signals” [referred to in this section as Ground Based 
Augmentation Systems (GBAS)]; (4) that frequencies below 112 MHz shall not be used for AM(R)S systems 
excluding GBAS (i.e., the only AM(R)S system that can operate in the 108-112 MHz segment is GBAS); and 
(5) that any AM(R)S operating in the 108-117.975 MHz band shall meet Standards and Recommended Practices 
(SARPs) requirements published in Annex 10 to the ICAO Convention on International Civil Aviation.  WRC-12 
deleted resolves 6 (which pertain to whether any further regulatory measures should be adopted to facilitate 
introduction of new AM(R)S systems) and certain made minor changes to Resolution 413.
Federal Communications Commission FCC 15-50
22
Ground Based Augmentation Systems (GBAS).  In 2003, the Commission adopted footnote US343, 
which states that Differential-Global-Positioning-System (DGPS) stations, limited to ground-based 
transmitters (i.e., GBAS), may be authorized on a primary basis in the 108-117.975 MHz band (as well as 
the 1559-1610 MHz band) for the specific purpose of transmitting DGPS information intended for aircraft 
navigation.
126
In its WRC-07 recommendations for domestic implementation, NTIA recommended that 
we add RR 5.197A to the U.S. Table and that we remove the 108-117.975 MHz band from the text of 
footnote US343.
127
47. Proposal.  The Commission proposed to add new footnote US197A to the 
108-117.975 MHz band that would incorporate the text of RR 5.197A and add the following sentence: 
“AM(R)S use of the band 108-117.975 MHz shall not constrain the use of the band 88-108 MHz by 
stations in the broadcasting service operating in accordance with 47 CFR Part 73.”
128
  The Commission 
made this proposal because of existing claims of harmful interference to ARNS use of the 
108-117.975 MHz band from FM broadcasting stations, which operate in the adjacent 88-108 MHz 
band.
129
  The Commission stated its belief that the potential for similar interference concerns to arise with 
an AM(R)S allocation should be addressed in this proceeding.  In particular, the Commission noted that 
Resolution 413 states “that no compatibility criteria currently exist between FM broadcasting systems 
operating in the frequency band 87-108 MHz and the planned additional aeronautical systems in the 
adjacent band 108-117.975 MHz using aircraft transmission” and “that no compatibility criteria currently 
exist between digital sound broadcasting systems capable of operating in the frequency band at about 
87-108 MHz and aeronautical services in the band 108-117.975 MHz.”
130
The Commission also stated 
that it was concerned that any interference resolution is further complicated by the Federal Aviation 
Administration’s (FAA’s) proposed frequency notification requirements for FM radio stations that are 
still pending,
131
and because the FAA has not implemented the International Civil Aviation Organization’s
(ICAO’s) improved performance standards for Instrument Landing System (ILS) localizer, VOR, and 
VHF communications receivers.
132
48. The Commission proposed to revise and renumber footnote US343 by removing the 
108-117.975 MHz band and by renumbering this footnote in frequency order as US85.

The Commission also authorized the use of DGPS in the 108-117.975 MHz band on a non-developmental basis 
and required DGPS receivers to meet the International Civil Aviation Organization’s (ICAO’s) minimum 
interference immunity requirements.  Review of Part 87 of the Commission's Rules Concerning the Aviation Radio 
Service, Report and Order and Further Notice of Proposed Rule Making, 18 FCC Rcd 21432, 21457-59 (2003).  As 
of March 7, 2015, NTIA has authorized two DGPS stations to operate in the 108-117.975 MHz band.  As of 
March 31, 2015, the Commission has issued 358 active call signs in the Aviation Radionavigation (AR) Radio 
Service for operations in the 108-117.975 MHz band, 7 of which authorize DGPS stations.
127
See NTIA WRC-07 Recommendations at 2 (revised text of footnote US343) and 14 (modifications to the 
108-117.975 MHz band).  NTIA also recommends removing the last sentence from footnote US343 (i.e., “Such use 
shall be in accordance with ITU Resolution 413 (WRC-03)”) because Resolution 413 does not apply to the 
1559-1610 MHz band.

Commission stated that DGPS stations in the 108-117.975 MHz band would be authorized under the 
proposed AM(R)S allocation that would be codified in footnote US197A, if it is added to the U.S. 
Table.
134
49. Comments.  The Boeing Company (Boeing) supports the addition of a footnote 
implementing RR 5.197A, but opposes the additional language proposed in the WRC-07 NPRM.  It argues 
that the language of RR 5.197A as agreed on at WRC-07 is the result of a carefully crafted compromise 
among the aviation industry, regulators, and the broadcast industry that should not be modified in a 
U.S. footnote.  It contends that the additional language could be misconstrued to equate the AM(R)S as 
secondary or otherwise subordinate to broadcast operations, which was not the intent of the 
administrations that crafted and agreed to the new footnote.
135
  Subsequently, the FAA informed the 
Commission that it is no longer pursuing its proposed frequency notification requirements for FM radio 
stations operating in the 88-108 MHz band.
136
50. Decision.  In view of the FAA’s decision to not pursue its proposed frequency 
notification requirements for FM radio stations, we implement NTIA’s recommended changes in the 
108-117.975 MHz band.  Specifically, we add a reference to RR 5.197A in the 108-117.975 MHz band 
within the U.S.  Table.  By this action, we allocate the 108-117.975 MHz band to the AM(R)S on a 
primary basis for Federal and non-Federal use, limit the use of this allocation to systems operating in 
accordance with recognized international aeronautical standards, require that such use be in accordance 
with Resolution 413 (Rev.WRC-12), and limit AM(R)S use of the 108-112 MHz sub-band to systems 
composed of ground-based transmitters and associated receivers that provide navigational information in 
support of air navigation functions.  Because DGPS stations in the 108-117.975 MHz band will be
authorized under the AM(R)S allocation, now codified in RR 5.197A, we revise footnote US343 to 
remove the reference to the 108-117.975 MHz band and renumber this footnote as US85.
137
2. Aeronautical Mobile Service Allocation in the 5091-5150 MHz Band
51. In this section, we allocate the 5091-5150 MHz band to the aeronautical mobile service 
(AMS) on a primary basis, but limit the use of this allocation to surface applications at airports, 
commonly referred to as the Aeronautical Mobile Airport Communications System (AeroMACS), and to 
Aeronautical Mobile Telemetry (AMT) transmissions from aircraft.

137
Because ITU Resolution 413 (WRC-12) applies only the 108-117.975 MHz band, which we are removing from 
footnote US343, we are also removing a now unneeded second sentence (i.e., “Such use shall be in accordance with 
ITU Resolution 413 (WRC-03).”).
138
AMT is a mobile service for the flight testing of aircraft in which an aircraft station transmits the results of 
measurements made onboard an aircraft, including those related to the functioning of the aircraft.  AMT operations 
are primarily authorized in the 1435-1525 MHz, 2200-2290 MHz (Federal only), and 2360-2395 MHz bands.  We 
note that the term AeroMACS refers to the emerging wireless communications networks in the 5091-5150 MHz 
band which operates in the airport surface domain.  See “AeroMACS System Characterization and Demonstrations,” 
March 2013, by Robert Kerczewski, et al., at 1, 9 (NASA/TM—2013-216497). More specifically, AeroMACS has 
been developed to provide broadband wireless communications between aircraft and other ground vehicles, as well 
as between critical fixed assets.  The potential services and applications provided by AeroMACS can be grouped 
into three major categories: Air Traffic Control (ATC) and Air Traffic Management (ATM) and infrastructure, 
airline operations, and airport and/or port authority operations.  See Future Aeronautical Communications, Chapter 
12, titled “Aeronautical Mobile Airport Communications System (AeroMACS),” by James M. Budinger and 
Edward Hall (2011), Section 3.2, p. 241.  See also “Aeronautical Mobile Airport Communications System 
(AeroMACS) for Access to SWIM,” by NASA/GRC/James Budinger, Nov. 3, 2010 (NASA presentation).
Federal Communications Commission FCC 15-50

52. Background.  In the U.S. Table, the 5091-5150 MHz band is allocated to the aeronautical 
radionavigation service (ARNS) on a primary basis for Federal and non-Federal use.  Footnote US260 
states that AMS communications that are an integral part of ARNS systems may also be satisfied in that 
band.  In addition, there are three footnotes (RR 5.367, US444, US444A) that contain pre-WRC-12 text,
which pertain to the 5091-5150 MHz band and we update in this Report and Order.  RR 5.367 states that 
the 5000-5150 MHz band is also allocated to the aeronautical mobile-satellite (R) service (AMS(R)S) on 
a primary basis.
139
  Footnote US444 states that use of the 5030-5150 MHz band for Microwave Landing 
System (MLS) requirements takes precedence over other uses of the band.  Footnote US444A states, inter 
alia, that the 5091-5150 MHz band is allocated to the fixed-satellite service (FSS) (Earth-to-space) on a 
primary basis for feeder links to non-geostationary satellite orbit systems in the mobile-satellite service 
(NGSO MSS), but prohibits new assignments after January 1, 2012.
140
53. In its Proposals for WRC-07, the United States identified the 5091-5150 MHz band to 
support additional aviation communication needs.  It noted that ICAO recommended 5091-5150 MHz as 
a suitable band for surface applications that can support high data throughput, and that studies have
shown that such AM(R)S applications can share this band with both the existing FSS and new AMT 
systems.  Consistent with these proposals, WRC-07 allocated the 5091-5150 MHz band to the AMS on a 
primary basis.  WRC-07 also adopted RR 5.444B, which restricts AMS use of the 5091-5150 MHz band 
to: 1) AM(R)S systems operating in accordance with “international aeronautical standards,”
141
limited to 
surface applications at airports, and in accordance with Resolution 748 (i.e., AeroMACS);
142
2) AMT 
                                                     
139
The mobile-satellite service (MSS) is a radiocommunication service: 1) Between mobile earth stations and one or 
more space stations, or between space stations used by this service; or 2) Between mobile earth stations by means of 
one or more space stations.  The MSS may also include feeder links necessary for its operation.  The aeronautical 
mobile-satellite service (AMSS) is a MSS in which mobile earth stations are located on board aircraft; survival craft 
stations and emergency position-indicating radiobeacon stations may also participate in this service.  The AMS(R)S 
is an AMSS reserved for communications relating to safety and regularity of flights, primarily along national or 
international civil air routes.  47 C.F.R. § 2.1(c).  Prior to WRC-12, RR 5.367 stated the 1610-1626.5 MHz and 
5000-5150 MHz bands are also allocated to the AMS(R)S on a primary basis, subject to agreement obtained under 
Radio Regulation No. 9.21.  WRC-12 removed the 5000-5150 MHz band from RR 5.367, directly listed this primary 
AMS(R)S allocation in the International Table, and restricted the use of this allocation by adopting RR 5.443AA and 
RR 5.443D.  In para. 61, infra, we maintain the status quo in the U.S. Table by moving the deleted text to footnote 
US367.  In paras. 222-232, infra, we propose to implement these and other WRC-12 allocation changes.
140
Two other U.S. footnotes apply to the 5091-5150 MHz band, but are not at issue in this proceeding.  Specifically, 
footnote US211 addresses radio astronomy protection and footnote US344 address Federal/non-Federal coordination 
of NGSO MSS feeder link earth stations.  The FSS is a radiocommunication service between earth stations at given 
positions, when one or more satellites are used; the given position may be a specified fixed point or any fixed point 
within specified areas; in some cases this service includes satellite-to-satellite links, which may also be operated in 
the inter-satellite service; the fixed-satellite service may also include feeder links for other space 
radiocommunication services.  47 C.F.R. § 2.1(c).
141
When WRC-07 adopted Resolution 748, it recognized “that ICAO publishes recognized international standards 
for AM(R)S systems.”  See Resolution 748 (WRC-07), recognizing b).
142
WRC-07 stated “that this new [AM(R)S] allocation is intended to support the introduction of applications and 
concepts in air traffic management which are data intensive, and which will support data links that carry 
safety-critical aeronautical data.”  WRC-07 resolved that: 1) any AM(R)S systems operating in the 5091-5150 MHz 
band shall not cause harmful interference to, nor claim protection from, ARNS systems; and shall meet the 
Standards and Recommended Practices (SARPs) requirements published in Annex 10 of the ICAO Convention on 
International Civil Aviation and the requirements of Recommendation ITU-R M.1827, to ensure compatibility with 
FSS systems operating in that band; and 2) that the coordination distance with respect to stations in the FSS 
operating in the band 5091-5150 MHz shall be based on ensuring that the signal received at the AM(R)S station 
from the FSS transmitter does not exceed -143 dB(W/MHz), where the required basic transmission loss shall be 
determined using the methods described in Recommendations ITU-R P.525-2 and ITU-R P.526-11.  See
Resolution 748 (WRC-07), considering h), resolves 1-3.  We note that WRC-12 revised Resolution 748 (WRC-07) 
by: 1) removing “aeronautical security” from considering f), 2) changing the word “precedence” to “priority” in

transmissions from aircraft stations in accordance with Resolution 418;
143
and 3) aeronautical security 
transmissions in accordance with Resolution 419.
144
  In addition, WRC-07 revised RR 5.444 and 
RR 5.444A by limiting the band in which MLS use takes precedence over other uses to the 
5030-5091 MHz band (i.e., by deleting the requirement that MLS use takes precedence over other uses of 
the 5091-5150 MHz band) and revised RR 5.444A by extending the date by four years (to January 1, 
2016) after which no new assignments may be made in the 5091-5150 MHz band to FSS earth stations 
providing feeder links for NGSO MSS systems.  Subsequently, WRC-12 modified RR 5.444B by 
removing aeronautical security transmissions from the list of AMS applications that are authorized to 
operate in the 5091-5150 MHz band.
145
  NTIA recommended that the Commission allocate the 
5091-5150 MHz band to the AMS on a primary basis for Federal and non-Federal use, that RR 5.444, 
RR 5.444B, and footnote USXXX5[1.5] (which we tentatively numbered as US111) be added to the 
U.S. Table, and that RR 5.444A be added to the non-Federal Table.
146
54. Proposal.  In the WRC-07 NPRM, the Commission proposed to allocate the 
5091-5150 MHz band to the AMS on a primary basis for Federal and non-Federal use, to limit the use of 
this AMS allocation to surface applications in the AM(R)S at airports, AMT, and aeronautical security 
transmissions by adding RR 5.444B to the U.S. Table, and to further limit AMT use to 52 specified flight 
test areas (with provisions for authorizing additional locations on a case-by-case basis) by adopting new 
footnote US111.
147
  While the Commission proposed to adopt the WRC-07 version of RR 5.444B, it noted 
that WRC-12 had modified this footnote by removing aeronautical security transmissions from the list of 
AMS applications authorized to operate in the 5091-5150 MHz band, and requested comment on whether 
it should implement the WRC-12 version of RR 5.444B.
148
  Finally, the Commission proposed to amend 
the U.S. Table by replacing footnotes US444 and US444A (which contained the pre-WRC-07 text of 
RR 5.444 and RR 5.444A) with the WRC-07 versions of RR 5.444 and RR 5.444A.
149
The Commission 
noted that this action would remove the precedence that MLS use currently has over other uses of the 
5091-5150 MHz band and would extend the date after which no new assignments may be made to earth 
stations providing feeder links for NGSO MSS systems to January 1, 2016.
150
55. Comments.  AFTRCC and Boeing were supportive of the Commission’s proposal to 
make the 5091-5150 MHz band available for AMT use.
151
  AFTRCC discussed how growth in telemetry 
data rates has taxed the capacity of existing AMT allocations and threatened the productivity and global 
competitiveness of U.S. aerospace manufacturers.
152
  Although both Boeing and AFTRCC recognize the

recognizing a), 3) updating the reference to Resolution 114 in recognizing c), and 4) updating the reference to 
Recommendation ITU-R P.526 in resolves 3.  See Resolution 748 (Rev.WRC-12).
143
In Resolution 418, WRC-07 specified the conditions for flight test operations in the 5091-5150 MHz band.  
WRC-12 revised Resolution 418 (WRC-07) by: 1) changing the word “precedence” to “priority” in recognizing a), 
2) deleting the reference to Resolution 419 and updating the reference to Resolution 748 in recognizing c), and 
3) adding a missing cross-reference (i.e., § 4 of Annex 1) in resolves 2.
144
In Resolution 419, WRC-07 specified the conditions for aeronautical security operations in the 5091-5150 MHz 
band.
145
WRC-12 also deleted Resolution 419, and reflected this change in Resolution 748 (see n.142, supra).
146
See NTIA WRC-07 Recommendations at 4 (recommended text for new footnote USXXX5[1.5], which we are 
codifying as footnote US111) and 37 (modifications to the 5091-5150 MHz band).

need to limit AMT use to specified flight test areas, both request that we authorize AMT operations at 
Boeing’s new manufacturing facility in Charleston, South Carolina.
153
  AFTRCC also supports 
referencing the authorized flight test areas in Part 87 of the Commission’s rules (the service rules for the 
Aviation Services), rather than in the Allocation Table.
154
56. Boeing states that the sensitivity of flight test receive equipment creates a risk of 
interference when flight test receivers are co-located or operate within the transmission range of the 
proposed AeroMACS use.
155
  Given the critical nature of flight test communications, Boeing urges the 
FAA to coordinate any AeroMACS deployment with operators of flight test receivers that could suffer 
harmful interference from co-channel operations in the 5091-5150 MHz band, and asks that the 
Commission require such coordination at the St. Louis – Lambert International (STL) and Seattle-Tacoma 
International (SEA) airports.
156
  In its reply comments, AFTRCC supports the Boeing request and urges 
that coordination also be required at four additional airports where AMT for flight testing of aircraft is 
conducted.
157
  Subsequently, NTIA recommended that we urge the operators of AM(R)S and AMT 
systems at the following six locations to cooperate and exchange information about planned deployments 
of their respective systems: 1) Boeing Field/King County Intl Airport, Seattle, WA; 2) Lambert-St. Louis 
Intl Airport, St. Louis, MO; 3) Charleston AFB/Intl Airport, Charleston, SC; 4) Wichita Dwight D. 
Eisenhower National Airport, Wichita, KS; 5) Roswell Intl Air Center Airport, Roswell, NM; and 
6) William P. Gwinn Airport, Jupiter, FL.
158
  NTIA also stated that additional airport locations may be 
addressed on a case-by-case basis.  Finally, NTIA recommended that, consistent with No. 4.10 of the ITU 
Radio Regulations, airport surface wireless systems operating in the AM(R)S (i.e., AeroMACS) be given 
priority in the 5091-5150 MHz band over AMT systems.
159
  
57. With regard to AeroMACS, NTIA changed its initial position and sought to have the 
5091-5150 MHz band also allocated to the fixed service on a primary basis for Federal and non-Federal 
use “to meet the needs of airport operations.”
160
  NTIA recommended that this fixed service allocation be 
limited to systems operating in conjunction with stations in the AM(R)S and in accordance with 
international aeronautical standards, limited to surface applications at airports.
161
  NTIA stated that even

Boeing suggests that its Charleston site (32° 52' 35.85" N, 80° 01' 49.70" W) could be added to footnote US111 
as either a separate or combined entry.  See Boeing Comments at 4-5 and AFTRCC Comments at 4.

S. Dortch, Secretary, FCC (ET Docket No. 12-338, filed January 21, 2015) at 1-2 (AFTRCC corrected the list of 
prospective AMT sites by revising the name of the Palm Beach-Dade and Seattle-Tacoma International Airport sites 
to the William P. Gwinn Airport and Boeing Field/King County International Airport, respectively).
158
See NTIA Final Supplement at 2-3.
159
See ITU Radio Regulations, No. 4.10 (“Member States recognize that the safety aspects of radionavigation and 
other safety services require special measures to ensure their freedom from harmful interference; it is necessary 
therefore to take this factor into account in the assignment and use of frequencies”).  AM(R)S is a safety service.  
See also NTIA Final Supplement at 1-3 (NTIA states that in the preparations for WRC-07, the sharing studies 
between AM(R)S and AMT in the 5091-5150 MHz band were done on the basis of geographic separation, with the 
understanding that AMT systems would only be operating at remote test ranges.  As a result, though a power 
flux-density limit was adopted to protect AM(R)S from airborne AMT transmissions, no constraints were placed on 
AM(R)S to protect AMT ground stations.).
160
See NTIA Third Supplement at 1.
161
Specifically, NTIA included a recommended U.S. footnote that also states that the requirements on, and 
protection of, the fixed service shall be the same as for the AM(R)S operating in accordance with Resolution 748 
(Rev.WRC-12).  See NTIA Third Supplement at 2.
Federal Communications Commission FCC 15-50
27
though the international allocation table does not include the fixed service in this band, the work within 
the ITU recognized that this service was integral to the systems being studied.
162
58. Decision.  We allocate the 5091-5150 MHz band to the AMS on a primary basis for 
Federal and non-Federal use, and limit the use of this allocation by adopting new footnote US444B.  This 
footnote restricts the use of the AMS allocation to AM(R)S systems, limited to surface applications at 
airports that operate in accordance with international aeronautical standards and Resolution 748, and to 
AMT transmissions from aircraft stations that operate in accordance with Resolution 418.  These use 
restrictions are based on the WRC-12 version of RR 5.444B.
59. In response to NTIA’s request, we expressly permit aeronautical fixed communications
that are an integral part of the AeroMACS system to be authorized on a primary basis for Federal and 
non-Federal use.
163
  The AeroMACS system has been designed to support both fixed and mobile 
applications, and is consistent with the intent of the U.S. Proposals and WRC-07’s actions.
164
  These fixed 
applications will be part of a larger system of surface applications at airports.  Adopting NTIA’s request 
of extending primary status to these fixed applications does not undercut, nor does it fundamentally depart 
from, our initial proposal.  This allocation, together with the AM(R)S allocation, is expected to support 
the introduction of applications and concepts in air traffic management that are data intensive.  This 
decision is also codified in new footnote US444B.
60. We also adopt our proposal to restrict AMT use of the 5091-5150 MHz band to the 
52 flight test areas listed in proposed footnote US111 and to allow additional locations to be authorized 
for flight testing on a case-by-case basis.
165
  At the request of commenters, we authorize the use of this 
AMT band at Boeing’s new facility in Charleston, South Carolina as an additional location.
166
  Also, at 
the request of NTIA, we urge operators of AM(R)S and AMT systems at the six requested airports to 
cooperate with each other and exchange information about planned deployments of their respective 
systems.
167
  Such cooperation will enhance the prospects for compatible sharing of the band.  We further 
note that other airport locations may be addressed in a similar manner on a case-by-case basis.  Finally, at 
NTIA’s request, airport surface wireless systems operating in the AM(R)S, i.e., AeroMACS, will have 
priority over AMT systems in the 5091-5150 MHz band.
61. We take four additional actions.  First, we implement WRC-07’s decision to reduce the 
amount of spectrum in which MLS requirements take precedence over other uses by removing the 
5091-5150 MHz band from footnote US444.
168
  Second, we extend the date after which no new 
assignments may be made to FSS earth stations providing feeder links for NGSO MSS systems to 
January 1, 2016 by revising footnote US444A.  Third, with the concurrence of NTIA, we decline to 
                                                     
162
See NTIA Third Supplement at 1.
163
We have simplified NTIA’s recommended footnote by paralleling the text of footnote US260.
164
Specifically, the Commission explained that the proposed new AM(R)S allocation was intended to allow for 
operations in the 5091-5150 MHz band of “evolving navigation and surveillance applications” that might not 
conform to the traditional definition of a “radionavigation service.”   See WRC-07 NPRM, 27 FCC Rcd at 14626, 
para. 65.  AeroMACS is one such “evolving navigation and surveillance application.”
165
As stated in para. 55, supra, AFTRCC supports referencing the authorized flight test areas in Part 87 of the 
Commission’s rules, rather than in the Allocation Table.  However, for administrative convenience, we decline to do 
so at this time.  That is, because we are now considering AMT allocations in the 4400-4940 MHz and 5925-6700 
MHz bands, we believe that it simplifies this proceeding to more closely follow the NTIA recommendations.
166
See para. 55, supra.
167
These locations are: 1) Boeing Field/King County Intl Airport, Seattle, WA; 2) Lambert-St. Louis Intl Airport, 
St. Louis, MO; 3) Charleston AFB/Intl Airport, Charleston, SC; 4) Wichita Dwight D. Eisenhower National Airport, 
Wichita, KS; 5) Roswell Intl Air Center Airport, Roswell, NM; and 6) William P. Gwinn Airport, Jupiter, FL.
168
As a result, the requirements of the MLS will only have precedence over other uses in the 5030-5091 MHz band.
Federal Communications Commission FCC 15-50
28
authorize aeronautical security transmissions in the 5091-5150 MHz band.  These three actions conform
these Commission’s rules with the 2012 ITU Radio Regulations.  Consistent with NTIA’s WRC-12 
Implementation Recommendations, we codify these decisions by revising the text of footnotes US444 and 
US444A in the Allocation Table.
169
Fourth, we move the portion of RR 5.367 that was deleted by 
WRC-12 into footnote US367.  This action allows us to update the International Table within 
Section 2.106, while maintaining the status quo in the U.S. Table until such time as we can consider any 
pertinent comments that may be filed in response to the WRC-12 Notice.
170
3. Deletion of the AMT Allocations from 2310-2320 MHz and 2345-2360 MHz
62. Background.  The Wireless Communication Service (WCS) operates in the 
2305-2320 MHz and 2345-2360 MHz bands, and the Satellite Digital Audio Radio Service (SDARS) in 
the 2320-2345 MHz band.  Per footnote US339, the 2310-2320 MHz and 2345-2360 MHz bands are also 
available on a secondary basis to the WCS for Aeronautical Mobile Telemetry (AMT) and associated 
telecommand operations for flight testing of aircraft, missiles, and their major components.  This footnote 
also states that two frequencies (2312.5 MHz and 2352.5 MHz) are available to Federal and non-Federal 
stations for telemetry and telecommand operations of expendable and reusable launch vehicles 
(commercial launch frequencies).
63. Proposal.  In the WRC-07 NPRM, the Commission proposed to delete the unused 
non-Federal AMT allocation in the 2310-2320 MHz band from footnote US339, remove non-Federal 
access to the two commercial launch frequencies (which are not being used), and renumber the revised 
text as footnote US100.
171
  The Commission solicited comment on whether – effective at the conclusion 
of an appropriate phase-in period (e.g., five years) for the proposed new AMT band (5091-5150 MHz) – it 
should delete the non-Federal AMT allocation in the 2345-2360 MHz band from footnote US339 or, 
alternatively, grandfather indefinitely the three existing licenses that authorize AMT operations in that
band.
172
64. Comments.  Both Boeing and AFTRCC support deletion of the non-Federal AMT 
allocations from the 2310-2320 MHz and 2345-2360 MHz bands.
173
  Boeing states that the “use of the 
2310-2320 MHz band for the Wireless Communications Service makes the band unusable for flight test 
operations.”
174
  AFTRCC states that the non-Federal AMT allocation at 2345-2360 MHz:
“is of limited utility due to its secondary status which precludes its use for safety-related 
applications. Given that and the impending development of LTE systems in that band, AFTRCC
would urge that the allocation be removed.  However, recognizing that there are a few (three) 
                                                     
169
In the WRC-07 NPRM, the Commission proposed to replace footnotes US444 and US444A with RR 5.444 and 
RR 5.444A, respectively.  After considering the NTIA WRC-12 Implementation Recommendations, we decline to 
implement these proposals for administrative convenience.  We note that this is not a substantive action, but merely 
a display change.  See Letter from Karl B. Nebbia, Associate Administrator, Office of Spectrum Management, 
NTIA, to Julius P. Knapp, Chief, Office of Engineering and Technology, ET Docket No. 12-338, filed March 28, 
2013 (NTIA WRC-12 Implementation Recommendations) at p. 15.  See also Appendix D for the text of footnotes 
US444, US444A, and US444B.
170
See Appendix D for the text of footnote US367.  In the WRC-12 Notice, we propose to: 1) directly list a primary 
AMS(R)S allocation in the frequency range 5000-5150 MHz, 2) limit the use of that allocation by footnotes 
RR 5.443AA and RR 5.443D, and 3) delete footnote US367 from the Allocation Table.  See paras. 231-232, infra.
171
The Commission also proposed to remove the 2310-2320 MHz band from various sections in Part 87 of its rules.

licensees which still hold authorizations for this spectrum, AFTRCC would urge that a reasonable 
period of time be allowed for a phase-out of the allocation, either five years or the end of each 
respective licensee's current license, whichever is longer.”
175
65. Decision.  We remove the non-Federal AMT allocation from the 2310-2320 MHz band 
and restrict the availability of the non-Federal AMT allocation in 2345-2360 MHz band to incumbent 
licensees.  We also remove the availability of two unused commercial launch frequencies.  To provide for 
the orderly relocation of incumbent AMT operations from the 2345-2360 MHz band, we establish a 
transition period that will end on January 1, 2020.
176
  We codify these decisions by modifying the text of 
footnote US339 and by renumbering the resultant text as footnote US100.
177
  Because we are adopting the 
transition plan that is consistent with AFTRCC’s recommendation, we agree with Boeing that there will 
likely be little to no adverse impact on AMT operations.
4. Deletion of the Radionavigation Service Allocation from 24.75-25.05 GHz 
66. Background.  In the International Table, the 24.75-25.25 GHz band is allocated to the 
fixed-satellite service (FSS) (Earth-to-space) (i.e., FSS uplinks) on an exclusive basis in Region 2.  
RR 5.535 states that feeder links for the broadcasting-satellite service (BSS feeder links) have priority 
over other FSS uses in the 24.75-25.25 GHz band, and that all other FSS uses in the band “shall protect 
and shall not claim protection from existing and future” BSS feeder link networks, i.e., these additional 
FSS uses operate on a non-interference and unprotected basis to BSS feeder links.
67. In the U.S. Table, the 24.75-25.05 GHz and 25.05-25.25 GHz bands are allocated to the 
FSS (Earth-to-space) on a primary basis for non-Federal use.  Footnote NG167 states that use of these 
FSS allocations is restricted to BSS feeder links.
178
  The 24.75-25.05 GHz band is also allocated to the 
radionavigation service (RNS) on a primary basis for Federal and non-Federal use and the 
25.05-25.25 GHz band is allocated to the fixed service on a primary basis for non-Federal use.
179
68. To make the 24.75-25.05 GHz band available for end-user uplinks in the provision of 
two-way satellite broadband services by BSS licensees, Xanadoo Company and Spectrum Five LLC 
(Xanadoo/Spectrum Five) requested that the Commission delete the Federal and non-Federal RNS 
allocations from the 24.75-25.05 GHz band.

175
AFTRCC Comments at 5.
176
This date will provide for a roughly 5-year transition period and is well after the latest expiration date of any 
current license in the band.
177
We also remove unneeded text from footnote US339 (“The broadcasting-satellite service (sound) during 
implementation should also take cognizance of the expendable and reusable launch vehicle frequencies 2312.5 and 
2352.5 MHz, to minimize the impact on this mobile service use to the extent possible.”).  We note that these 
frequencies are both within segments of the original SDARS allocation that were reallocated for terrestrial use 
(2305-2320 and 2345-2360 MHz) and that are now licensed to WCS operators.  Therefore, the deletion of this text 
clarifies the footnote without affecting any user.  See Appendix D for the text of footnote US100.

69. Proposal.  In the WRC-07 NPRM, the Commission noted that the 24.75-25.05 GHz band 
is not allocated to the RNS in the International Table and that the RNS allocation in this band is unused in
the United States, and solicited comment on whether there is any planned use that would justify retention 
of the RNS allocation in the U.S. Table.
181
  The Commission stated that if it decides to remove the RNS 
allocation from the 24.75-25.05 GHz band, it would amend NG167 by employing the RR 5.535 text in the 
24.75-25.05 GHz band,
182
remove the Part 87 cross-reference from the Allocation Table, and remove the 
24.75-25.05 GHz band from Sections 87.173(b) and 87.187(x).  Accordingly, the Commission sought 
comment on what actions it should take in this regard.
70. Comments.  DirecTV, LLC (DirecTV), the only commenter on this issue, urges the 
Commission to implement its proposals to delete the RNS allocation from the 24.75-25.05 GHz band and 
make associated conforming changes to the Commission’s rules.
183
  It asserts that the additional capacity 
in this band that would result could be used enhance its existing direct-to-home multichannel video 
service, and more generally, will serve the public interest by conforming the Commission’s frequency 
allocation to the International Table and eliminating any potential conflict with licensees in the 17 and 
24 GHz BSS bands.
184
  DirecTV further asserts that given that there are no RNS systems operating in the 
band today and no demonstrated need for such operations in the future, there are no offsetting costs to 
modifying the allocation as proposed.
185
71. Decision.  We are removing the RNS allocation in the 24.75-25.05 GHz band from the 
Federal and non-Federal Tables.  As a result of this action, the 300 megahertz of RF spectrum contained 
within this band is allocated exclusively to the FSS (Earth-to-space) for non-Federal use.
186
  We are also 
expanding the permitted uses of this FSS allocation from BSS feeder links to all FSS uses.  Consistent 
with the international use limitation contained in RR 5.535, we are providing BSS feeder links with 
“priority” over all other FSS uses, i.e., all other FSS uses “shall protect and shall not claim protection 
from existing and future” BSS feeder link networks.  We codify this decision in the Allocation Table by 
revising the text of footnote NG167 to parallel the text of RR 5.535 for the 24.75-25.05 GHz band, and by 
renumbering the resulting footnote as NG535 (numbering based on RR 5.535).
187
  In addition, we remove 
the 24.75-25.05 GHz band from Sections 87.173(b) and 87.187(x) of the Commission’s rules, and 
consequently, delete the Part 87 cross-reference for this band from the Allocation Table.  While we adopt 
(Continued from previous page)                                                           
Five Petition), available at http://fjallfoss.fcc.gov/ecfs/document/view?id=7020409944, at 6.  In the WRC-07 NPRM, 
the Commission also noted but decided not to seek comment in this proceeding on an additional request by 
Xanadoo/Spectrum Five to establish rules permitting blanket licensing of two-way earth stations with end-user 
uplinks in the 24.75-25.05 GHz band.  See WRC-07 NPRM, 27 FCC Rcd 14637, para. 103, n.193 (stating that “these 
issues can best be addressed in a focused rulemaking proceeding”).
181
The Commission also noted that NTIA had not identified any operational radar use in the 24.75-25.25 GHz band.  
WRC-07 NPRM, 27 FCC Rcd at 14638, para. 104.
182
Under the proposed revision of footnote NG167, BSS feeder links operating on frequencies in the 
24.75-25.05 GHz band would have priority over other FSS uplink uses.  Any other FSS uses (i.e., non-BSS feeder 
link uses) would be required to protect, and could not claim protection from, existing and future BSS feeder-link 
operations.  As an administrative matter, we would also renumber footnote NG167 as NG535 (based on RR 5.535).
183
See DirecTV Comments at 1-3.
184
DirecTV also states that it is licensed for two BSS satellites which use the 24.75-25.25 GHz band for 
Earth-to-space feeder links.  See DirecTV Comments at 1-2.

An additional 200 megahertz of spectrum in this range (25.05-25.25 GHz) remains allocated to the FSS and FS 
on a co-primary basis for non-Federal use.
187
We are maintaining the existing text from footnote NG167 for the 25.05-25.5 GHz band, i.e., the use of the 
25.05-25.25 GHz band by the FSS (Earth-to-space) is limited to BSS feeder links.  See Appendix D for the text of 
footnote NG535.

in part the Xanadoo/Spectrum Five proposal with respect to removal of the unused RNS allocation, we 
find that no further action on the other elements of their petition is warranted at this time.  If, in the future,
requests for licensing or other market developments suggest a demand exists for additional FSS uses of 
the 24.75-25.05 GHz band, we will initiate a separate rulemaking proceeding to examine whether any 
specific rules are necessary to support such uses consistent with the priority afforded to BSS feeder links 
in this band.
5. Updates to Part 87 Aviation Services Rules
72. Consistent with the changes proposed to the Allocation Table in the WRC-07 NPRM, the 
Commission proposed to make amendments to nine rule sections in Part 87 of its rules.
188
  AFTRCC, the 
only party to comment on these proposals, supports the Commission’s proposal to add AFTRCC 
coordination duties for the 5091-5150 MHz band.
189
73. Decision. We adopt our proposals.  Specifically, we amend Part 87 of the Commission’s 
rules to bring the new AMT allocation in the 5091-5150 MHz band into immediate effect and to remove 
all references to the unused secondary AMT allocation in the 2310-2320 MHz band.
190
  We also amend 
Part 87 by removing all references to two previously deleted AMT bands (1525-1535 MHz and 
2320-2345 MHz) and by listing a previously allocated AMT band (2390-2395 MHz, generally shown as 
part of the larger 2345-2395 MHz band) in all appropriate rule sections.
191
  As a result of this action, the 
correct AMT bands – 1435-1525 MHz, 2345-2360 MHz (until the conclusion of the transition period), 
2360-2395 MHz, and 5091-5150 MHz – will be specified throughout Part 87.  In addition, we amend 
Part 87 of the Commission’s rules as follows:
• Add the term “flight telemetering mobile station” to the list of definitions in Section 87.5, use 
this term in the affected rules, clarify that five frequencies in the 1435-1525 MHz band 
(1444.5, 1453.5, 1501.5, 1515.5, and 1524.5 MHz) are shared with flight telemetering mobile 
stations “on a co-equal basis” with AMT operations, and renumber footnote US78 as US343.
• Amend Section 87.133(f) by specifying that the carrier frequency tolerance of all transmitters 
that operate in the 5091-5150 MHz band is 0.005 percent, and revise the existing text to 
specify that the carrier frequency tolerance of all transmitters that operate in the 1435-1525 
MHz or 2345-2395 MHz band is 0.002 percent.
• Update the AMT bands listed in Section 87.137(a), note 8, Section 87.139, and 
Section 87.173(b).
• Amend Section 87.173(b) by revising the entry for the “5000-5250 MHz” band to read 
“5030-5150 MHz”
192
and by adding an entry for the “24450-24650 MHz” band in the 
frequency table.  We also specify that the 24450-24650 MHz band is available under Subpart 
F (Aircraft Stations) and Subpart Q (Stations in the Radiodetermination Service), restrict the

192
In the WRC-07 NPRM, 27 FCC Rcd at 14627, para. 72, the Commission proposed to Section 87.173(b) by 
revising the entry for the “5000-5250 MHz” band to read “5030-5091 MHz.”  However, during the normal 
coordination process, the FAA requested that the MLS band be revised to read “5030-5150 MHz.”  We note that this 
request is consistent with footnote US444 (i.e., the 5030-5150 MHz band is to be used for the operation of the 
international standard system (microwave landing system) for precision approach and landing), and therefore, 
amend Sections 87.173(b) and 87.475(b)(11) (discussed in the last bullet within this paragraph) to provide for 
consistency in the rules.

use of this band to aircraft stations and radionavigation land stations, and list aeronautical 
radionavigation under the “Remarks” heading.
• Update the AMT bands listed in Section 87.187(p), by listing the 2360-2395 MHz (primary 
allocation) and 2345-2360 MHz (secondary allocation) bands and the three frequencies 
(2364.5 MHz, 2370.5 MHz, and 2382.5 MHz) that may be assigned for telemetry and 
associated telecommand operations of expendable and re-usable launch vehicles, whether or 
not such operations involve flight testing.
• Amend Section 87.303(d) to make the 5091-5150 MHz band available for aeronautical 
mobile telemetry.  Specifically, we insert introductory language listing the available bands; 
add new text to paragraph (d)(2) to specify use of the 5091-5150 MHz band and to cross-
reference footnote US111; and move and update the text that is currently listed in paragraph 
(d)(2) to paragraph (d)(3).
• Amend Section 87.475(b)(11) by revising the frequency band that can be used for microwave 
landing systems (MLS) from “5000-5250 MHz” to “5030-5150 MHz”
193
and 
Section 87.475(b)(14) by revising a frequency band that can be used for land-based 
radionavigation aids that operate with airborne radionavigation devices from “24,250-25,250” 
to “24,450-24,650” MHz.

coordinator actions, and engages in oversight of coordinator actions and practices.
195
  AFTRCC is the
“frequency advisory committee” specified in Section 87.305(a)(1) of the Commission’s rules.
196
  As a 
consequence of our actions in this proceeding, and at its explicit request,
197
we note that AFTRCC’s 
authority to act as the non-Federal coordinator for flight test frequencies now extends to the 
1435-1525 MHz, 2360-2395 MHz, and 5091-5150 MHz bands, and until the conclusion of the transition 
period, to the 2345-2360 MHz band.

C. Protecting Passive Sensors from Unwanted Emissions and In-Band Active Services
75. WRC-07 adopted provisions to protect passive sensors from the interference caused by 
the operation of certain radiocommunication services that: 1) transmit in two bands (10.6-10.68 GHz and 
36-37 GHz) that are allocated to the Earth exploration-satellite service (EESS) (passive) (i.e., in-band 
active services); and 2) transmit in frequency bands that are near or adjacent to five EESS (passive) bands
(1400-1427 MHz, 23.6-24 GHz, 31.3-31.5 GHz, 50.2-50.4 GHz, and 52.6-54.25 GHz).

In 1969, the FCC recognized AFTRCC as the Frequency Coordinating Advisory Committee for non-Federal 
flight test telemetry station assignments in the band 1435-1525 MHz, and in 1984, extended this recognition to the 
2310-2320, and 2345-2390 MHz bands.  See NTIA Manual, Section 8.3.17.  See also AFTRCC’s website for 
information titled “About AFTRCC,” which states that “AFTRCC is recognized by the FCC and NTIA as the 
non-government coordinator for assignment of flight test frequencies (by the FCC in the case of HF and VHF voice 
frequencies and by the FCC and NTIA in the case of the telemetry frequencies, 1435-1535 MHz and 2310-2390 
MHz);” (available at http://www.aftrcc.org/pages/organization.php).  See, e.g., 47 C.F.R. Section 27.73(a) (which 
names AFTRCC as the coordinator for the assignment of flight test frequencies in the 2360-2390 MHz band).

See AFTRCC Comments at 5 (stating that it is prepared to frequency coordinate the 5091-5150 MHz band).

WRC-07 added RR 5.338A to the International Table and adopted Resolution 750.
200
  In this section, we 
adopt new rules to protect passive sensors from certain non-Federal services that operate in the 
1435-1452 MHz, 10.6-10.68 GHz, 22.55-23.55 GHz, and 31-31.3 GHz bands.
201
1. Aeronautical Mobile Telemetry in the 1435-1452 MHz Sub-band
76. Background.  In the U.S. Table, the 1435-1525 MHz band is allocated to the mobile 
service on a primary basis for Federal and non-Federal use, restricted to aeronautical telemetry and 
associated telecommand operations for flight testing of aircraft and missiles, or their major components 
(i.e., AMT).
202
  The 1400-1427 MHz band is a passive band (i.e., no transmissions are authorized in this 
band) that is allocated, inter alia, to the EESS (passive).  For aeronautical telemetry stations that operate 
in the 1435-1452 MHz sub-band, WRC-07 adopted a recommended unwanted emissions level 
of -28 dBW in the 1400-1427 MHz passive band.
203
  NTIA recommends that we urge Federal and 
non-Federal operators of AMT stations in the 1435-1452 MHz sub-band to take all reasonable steps to 
ensure that their stations’ unwanted emissions power not exceed WRC-07’s recommended level.
Currently, the Commission’s rules for Aviation Services (Part 87) require that telemetry and telecommand 
operations in the 1435-1525 MHz band attenuate their emissions below 1434 MHz to at least                     
-55 dBW/3 kHz, which is equivalent to approximately -15.5 dBW/27 MHz.
204
77. Proposal.  The Commission proposed to encourage Federal and non-Federal operators of 
AMT stations that transmit in the 1435-1452 MHz sub-band to comply with WRC-07’s recommended 
unwanted emissions level of -28 dBW/27 MHz in the 1400-1427 MHz band by adding footnote US338A 
to the U.S. Table.
205
The Commission stated that if it adopted footnote US338A, it would also amend 
(Continued from previous page)                                                           
natural phenomena, including data relating to the state of the environment, is obtained from active sensors or passive 
sensors on Earth satellites; 2) similar information is collected from airborne or Earth-based platforms; 3) such 
information may be distributed to earth stations within the system concerned; and 4) platform interrogation may be 
included.  47 C.F.R. § 2.1(c).  This service has primary and secondary allocations in several higher frequency bands 
(UHF and above), which in some cases includes feeder links necessary for its operation.
200
WRC-12 revised RR 5.338A and Resolution 750.  We address the WRC-12 revisions in paras. 245-249, infra.  
Currently, RR 5.338A reads as follows:  In the bands 1350-1400 MHz, 1427-1452 MHz, 22.55-23.55 GHz, 
30-31.3 GHz, 49.7-50.2 GHz, 50.4-50.9 GHz, 51.4-52.6 GHz, 81-86 GHz and 92-94 GHz, Resolution 750 
(Rev.WRC-12) applies.  See ITU Radio Regulations, Resolution 750 (Rev.WRC-12).
201
In Section IV.D.3, “Rulemaking Proposals that Did Not Receive Any Specific Comments,” infra, we also adopt 
rules to protect passive sensors from certain non-Federal services that operate in the 1390-1395 MHz, 1427-1435 
MHz, 36-37 GHz, 49.7-50.2 GHz, 50.4-50.9 GHz, and 51.4-52.6 GHz bands.  See paras. 124-133 and 135-137, 
infra.
202
The mobile service is a radiocommunication service between mobile and land stations or between mobile 
stations.  (A mobile station is a station intended to be used while in motion or during halts at unspecified points and 
a land station is a station not intended to be used while in motion.)  47 C.F.R. § 2.1(c).  Five frequencies are shared 
with flight telemetry mobile stations.  Passive research is also conducted in this and other bands.  47 C.F.R. § 2.106, 
footnotes 5.341 and US78.

WRC-07 Final Acts, Resolution 750, Table 1-2.

47 C.F.R. § 87.139(e), (f).  See also 47 C.F.R. §§ 87.303(d)(2), 87.131, and 87.137(a) n.8.  Because the 
resolution bandwidths (BRES) (i.e., 27, 100, or 200 megahertz) used in the unwanted emissions limits/levels of ITU 
Resolution 750 are wider than the reference resolution bandwidths (BREF) used in the Commission’s rules (i.e., 
3 kilohertz, 4 kilohertz, or 1 megahertz), to compare the Commission’s existing unwanted emissions limits with 
WRC-07’s limits/levels, we use a correction factor of 10 log10[(BRES in megahertz)/(BREF in megahertz)] dB, which 
is added to the Commission’s unwanted emissions limits, to express the relevant per device unwanted emissions 
limit in the Commission’s rules over a wider bandwidth. See 47 C.F.R. § 74.637(c)(3).
205
The effect of NTIA’s recommendation would be that operators of AMT stations transmitting in the 
1435-1452 MHz sub-band would be urged to attenuate their stations’ unwanted emissions in the 1400-1427 MHz 
(continued….)
Federal Communications Commission FCC 15-50
34
Section 87.139 to reflect that decision in Part 87 of the Commission’s rules.  Additionally, it requested 
comment on whether AMT operators that cannot meet WRC-07’s recommended unwanted emissions 
level should be required to meet their operational requirements in the 1452-1525 MHz sub-band prior to 
operating in the 1435-1452 MHz sub-band.
206
78. Comments.  AFTRCC and Boeing, which were the only commenters to address this 
issue, do not oppose NTIA’s recommendation to encourage AMT stations transmitting in the 
1435-1525 MHz band to take all reasonable steps to limit their out-of-band emissions in the 
1400-1427 MHz band to -28 dBW/27 MHz.
207
AFTRCC states that “[w]hile the recommended NTIA 
limit is intended to provide greater protection for passive services over what is currently in the rules, in 
many, and perhaps most, cases, AMT equipment in the field already provides this additional
attenuation.”
208
  However, AFTRCC and Boeing both state that there is no justification for requiring that 
AMT operators access the 1435-1452 MHz sub-band only after first satisfying their spectrum 
requirements above 1452 MHz.
209
  Subsequently, NTIA requested that we require that AMT stations that 
do not meet WRC-07’s recommended unwanted emissions limit attempt to use the 1452-1525 MHz 
sub-band first before operating in the 1435-1452 MHz sub-band.
210
79. Decision.  We adopt our proposal by adding new footnote US338A to the Allocation 
Table.  Under footnote US338A, we encourage operators of aeronautical telemetry stations in the 
1435-1452 MHz sub-band to take all reasonable steps to ensure that their AMT transmitters’ unwanted 
emissions power does not exceed -28 dBW/27 MHz in the 1400-1427 MHz band.  In addition, we require 
operators of AMT stations that do not meet WRC-07’s recommended unwanted emissions level first 
attempt to operate in the 1452-1525 MHz sub-band before operating in the 1435-1452 MHz sub-band.  
Given that the record indicates that most AMT operations now meet the WRC-07 unwanted emissions 
level, this requirement should not impact most AMT operations.  We also amend Section 87.139 by 
adding paragraph (m) to reflect the text of footnote US338A.
211
2. Fixed Stations in the 10.6-10.68 GHz Band
80. Background.  In the U.S. Table, the 10.55-10.6 GHz and 10.6-10.68 GHz bands are 
allocated to the fixed service (FS) on a primary basis for non-Federal use.  The 10.6-10.68 GHz band is 
also allocated to the Earth exploration-satellite service (EESS) (passive) for Federal and non-Federal 
use.
212
In order to permit both passive sensors and fixed stations to operate in the 10.6-10.68 GHz band, 
the Commission adopted footnote US265, which requires that fixed stations not exceed an EIRP of 
(Continued from previous page)                                                           
band by an additional 12.31 dB from the existing limit of -15.69 dBW/27 MHz (shown in our rules as                        
-55 dBW/3 kHz) to -28 dBW/27 MHz.
206
WRC-07 NPRM, 27 FCC Rcd at 14650, para. 136.
207
See AFTRCC Comments at 6 and Boeing Comments at 5-6.  We note that while the term “out-of-band 
emissions” is sometimes used when referring to emissions outside of the frequency bands in which a device 
transmits, we use the term “unwanted” emissions, where appropriate throughout this Report and Order, to describe 
the emissions outside of the necessary bandwidth of the transmitting system.

See Appendix D for the text of footnote US338A and Section 87.139(m).
212
In addition, the 10.6-10.68 GHz band is allocated on a primary basis to the space research service (SRS) 
(passive), and per footnote US310, to the radio astronomy service (RAS), for Federal and non-Federal use.  Footnote 
US310 also states that the RAS will not receive protection from fixed stations that are licensed to operate in the one 
hundred most populous urbanized areas, and that the list of observatories operating in this band is contained in 
footnote US131.  The proposals in the WRC-07 NPRM do not directly impact SRS or RAS use of the 
10.6-10.68 GHz band.
Federal Communications Commission FCC 15-50
35
40 dBW and also requires that the power delivered to the antenna of a fixed station not exceed -3 dBW 
per 250 kilohertz.
213
81. Prior to WRC-07, RR 5.482 limited fixed stations that transmit in the 10.6-10.68 GHz 
band to a maximum EIRP of 40 dBW and also limited the power delivered to the antenna of these fixed 
stations to -3 dBW.
214
  WRC-07 revised RR 5.482 to remove the 40 dBW EIRP limit and adopted 
RR 5.482A, which states that Resolution 751 applies to the 10.6-10.68 GHz band.  Resolution 751 urges 
administrations to comply with specified sharing criteria when bringing into use fixed stations and 
passive sensors that operate in the 10.6-10.68 GHz band.
215
NTIA subsequently recommended that we 
amend footnote US265 in furtherance of the WRC-07 actions, e.g., that we urge operators of stations of 
point-to-point systems to limit the maximum transmitter power supplied to the input to the transmitting 
antenna to -15 dBW and the transmitting antenna elevation angle to a maximum of 20°, and that we 
remove the 40 dBW EIRP limit.
216
82. Proposal.  The Commission proposed to revise footnote US265 in a manner generally 
consistent with NTIA’s recommendations.
217
  Specifically, the Commission proposed to require that the 
power delivered to the antenna of a fixed stations transmitting in the 10.6-10.68 GHz band not exceed an 
antenna input power of -3 dBW (regardless of the bandwidth that is authorized); to add WRC-07’s 
recommended sharing criteria for fixed point-to-point systems to this footnote;
218
to urge licensees to 
employ automatic transmitter power control (ATPC);
219
to permit licensees holding a valid authorization 
as of the effective date of the Report and Order in this proceeding to continue to operate as authorized; 
and to renumber footnote US265 as US482.
220
  The Commission also stated that if it adopted proposed 
footnote US482, it would amend Section 101.111 of its rules to reflect that decision.
221
83. The Commission also analyzed licensing records in the band and requested comment on 
whether it should adopt additional measures to protect passive receivers.
222
  Specifically, the Commission 
                                                     
213
47 C.F.R. § 2.106.  The maximum allowable EIRP per polarization for fixed stations in the 10.6-10.68 GHz band 
is 40 dBW.  47 C.F.R. § 101.113(a).
214
We note that RR 5.482 does not apply in certain (35) countries in ITU Regions 1 and 3 and that the text of 
footnote US265 contains technical restrictions that generally mirror the pre-WRC-07 text of RR 5.482.
215
We note that, while WRC-12 revised Resolution 751, it did not revise the sharing criteria for the 10.6-10.68 GHz 
band.  See ITU Radio Regulations, Resolution 751 (Rev.WRC-12), resolves 1.  In particular, Tables 2 and 3 of 
Resolution 751 list the parameters and values for fixed stations of point-to-point and point-to-multipoint systems, 
respectively.
216
See NTIA WRC-07 Implementation Recommendations at 2 (modification of footnote US265).  Our AMT rules 
do not currently address transmitting antenna elevation angles.
217
WRC-07 NPRM, 27 FCC Rcd at 14654, para. 147. 
218
Because the Commission relocated the only fixed point-to-multipoint use from the 10.6-10.68 GHz band in 1993, 
it declined to propose adding the requested advisory language for point-to-multipoint systems and instead proposed 
to prohibit point-to-multipoint use of the 10.6-10.68 GHz band.

In a radio employing ATPC, the transmit power is reduced to a level needed for reliable communications.  When 
the receiver detects a reduction in signal level, a control signal is sent to the far end transmitter, instructing it to 
increase the power output to compensate for the signal reduction.  The power output is limited to the licensed 
(maximum) transmit power.  47 C.F.R. § 101.3.

Recent licensing information shows that at least 96 percent of all FS stations in the 10.6-10.68 GHz band supply 
not more than -3 dBW of transmitter power to the antenna and that approximately 21 percent of these stations supply 
not more than -15 dBW (31.6 mW) of transmitter power.  In addition, while only 41 percent of these transmitters list

asked whether it should prohibit fixed stations with main beam elevation angles greater than 20° from 
transmitting on frequencies in the 10.6-10.68 GHz band; require fixed stations using paired frequencies to 
transmit on frequencies in the 10.6-10.68 GHz band using the lower elevation angle; and require the use 
of ATPC.
223
  In addition, the Commission observed that many applicants will continue to request -3 dBW 
as the maximum transmitter power delivered to the antenna, and it requested comment on whether it
should urge licensees to limit the off-axis EIRP above 20° to -10 dBW.
224
  Finally, the Commission 
requested comment on whether it should remove or revise the 40 dBW EIRP limit.
225
84. Comments.  We received comments from the National Academy of Sciences, through the 
National Research Council’s Committee on Radio Frequencies (hereinafter, CORF) and Comsearch.  
CORF supports the adoption of rules that would: 1) prohibit fixed stations with main beam elevation 
angles greater than 20° from transmitting on frequencies in the 10.6-10.68 GHz band; 2) require fixed 
stations using paired frequencies to transmit on frequencies in the 10.6-10.68 GHz band using the lower 
elevation angle; and 3) require the use of ATPC.
226
CORF states that the first two proposals deal with 
transmit angles, which correspond to local Earth incidence angles of the main beams on most 
conical-scanning spaceborne microwave radiometers, and that these actions would therefore protect 
passive sensors that use this band.  CORF states that the use of ATPC would reduce the required transmit 
power most of the time, and would therefore have a significant positive effect on reducing radio 
frequency interference.  Regarding the proposal to urge licensees to limit off-axis EIRP above 20° 
to -10 dBW, CORF deems this level to be too high and recommends that we follow the recommendations 
in Report ITU-R RS.2096.
227
85. Comsearch opposes the adoption of a requirement that fixed stations using paired 
frequencies transmit on frequencies in the 10.6-10.68 GHz band using the lower elevation angle.  
Comsearch argues that such a requirement would frustrate efficient frequency planning and serve to limit 
the capacity and growth of point-to-point microwave systems, while in return “do[ing] almost nothing to

an elevation angle, essentially all of these transmitters (all but two of 2,689) have an elevation angle of 20° or less.  
WRC-07 NPRM, 27 FCC Rcd at 14654, para. 148.
223
The Commission noted that interference simulations indicate that the interference power level would increase by 
approximately 8 dB (from -125 to -117 dBW) when the elevation angles of the main beam of fixed stations are 
increased from 20° to 25°.  Further, we note that the ITU-R Report states that “FS elevations above 5° are rare in 
actual operating systems.”  See Report ITU-R RS.2096, figure 23, p. 38; first Note, p. 39.  Licensing information 
also shows that 98 percent of the transmitters listing an elevation angle have an elevation angle of 5° or less.  Id.
224
Id.  Note 3 of Resolution 751 reads as follows: “In the case of point-to-point fixed service used for unidirectional 
transmissions for broadcasting applications, the maximum transmitter power at the antenna port may be increased up 
to -3 dBW.  For such applications, administrations are urged to limit the off-axis EIRP above 20° elevation to a level 
of -10 dBW.”  See ITU Resolution 751, Annex 1, Table 2, n.3.

protect EESS.”
228
It argues that the only way to provide “significant benefit” to EESS is by prohibiting 
the use of elevation angles above 20 degrees.
229
86. Decision.  We adopt the proposed changes to footnote US265.  Specifically, we restrict 
the transmitter power delivered to the antenna to not more than -3 dBW, add WRC-07’s recommended 
sharing criteria for fixed point-to-point systems (and explicitly restrict use of the 10.6-10.68 GHz band to 
fixed point-to-point systems), urge (but not require) the use of ATPC, and permit licensees holding a 
valid authorization as of the effective date of this Report and Order to continue to operate as authorized.  
Based on the record, we find we should also restrict the elevation angle of the antenna main beam of fixed 
stations that transmit in the 10.6-10.68 GHz band to a maximum of 20°, instead of simply urging 
operators of fixed stations to apply this limit.  Doing so will ensure that EESS operations are afforded 
protection, and does not appear to impose a significant burden on existing operations.  We do not adopt 
the other proposals that were discussed in the WRC-07 NPRM.  Specifically, we find that making ATPC 
use mandatory would impose costs that are unwarranted, given our decision to adopt a 20° elevation angle 
limit.  We also find compelling Comsearch’s arguments about the burdens associated with requiring fixed 
stations using paired frequencies to transmit on frequencies in the 10.6-10.68 GHz band using the lower 
elevation angle.  By contrast, our decision to adopt of a maximum 20° elevation angle limit will provide
benefits to EESS operations with little or no effect on 10.6-10.68 GHz band licensees.
87. We codify this decision by revising the text of footnote US265 and renumbering this
footnote as US482.  We amend Section 101.111 by adding new paragraph (d)(1)  to reflect this decision 
in Part 101 of the Commission’s rules.

3. Inter-Satellite Links in the 22.55-23.55 GHz Band
88. Background.  In the U.S. Table, the 22.55-23.55 GHz band is allocated to the fixed
service, the mobile service, and the inter-satellite service (ISS) on a primary basis for Federal and 
non-Federal use.  Footnote US278 states that non-geostationary satellite orbit (NGSO) ISS systems may 
operate in this band on a secondary basis to geostationary inter-satellite links.  The 23.6-24 GHz band is 
allocated to the Earth exploration-satellite service (EESS) (passive), radio astronomy service, and space 
research service (passive) on a primary basis for Federal and non-Federal use.
231
  In addition, 
Section 25.202(f)(3) sets forth the unwanted emissions limit in the 23.6-24 GHz band for satellite 
operations in the 22.55-23.55 GHz band.
232
                                                     
228
Comsearch explains that, in frequency planning for point-to-point networks, it is desirable to follow a matched 
high/low frequency plan at each site.  A matched high/low plan at a site means that all the transmitters operate in 
one half of the band (10.550-10.615 GHz) and all the receivers operate in the other half of the band 
(10.615-10.680 GHz), or vice versa.  While a receiver could be exposed to a high interference level from a 
co-located transmitter, the matched high/low plan provides frequency separation so the transmitter and receiver 
filtering can mitigate the exposure and minimize the potential for interference.  Following a matched high/low plan 
also maximizes the number of links and channels that can be used at each site thus allowing for increased capacity 
and growth.
229
Id.  Comsearch also notes that 10 GHz point-to-point antennas rarely use elevation angels above 5 degrees.

47 C.F.R. § 25.202(f)(3).  Except for SDARS terrestrial repeaters, the mean power of unwanted emissions in the 
passive band (23.6-24 GHz) shall be attenuated below the mean output power of the transmitter as follows: 
43 + 10 log10 (transmitter power in watts) dB in any 4 kilohertz band (-43 dBW/4 kHz), the center frequency of 
which is removed from the assigned frequency by more than 250 percent of the authorized bandwidth, which is 
equivalent to an emissions limit of approximately 4 dBW/200 MHz.  Id.  See n.204, supra, for the methodology 
used to express the existing unwanted emissions limit in Section 25.202(f)(3) over a wider bandwidth.
Federal Communications Commission FCC 15-50

89. In Resolution 750, WRC-07 adopted mandatory unwanted emissions limits of -36 dBW 
in any 200 megahertz of the 23.6-24 GHz EESS (passive) band for NGSO ISS systems that operate in the 
22.55-23.55 GHz band for which complete advance publication information is received by the ITU (i.e., 
its Radiocommunication Bureau) before January 1, 2020, and -46 dBW in any 200 megahertz of the 
23.6-24 GHz  EESS (passive) band for NGSO ISS systems that operate in the 22.55-23.55 GHz band for 
which complete advance publication information is received by the ITU on or after January 1, 2020.
233
  
NTIA recommended that the Commission adopt these mandatory unwanted emissions limits.
234
90. Proposal.  In the WRC-07 NPRM, the Commission proposed to implement WRC-07’s 
mandatory unwanted emissions limits for all new NGSO ISS systems that operate in the 22.55-23.55 GHz 
band by adding footnote US145 to the Allocation Table.  The Commission stated that if these limits are 
adopted, then new NGSO ISS satellites authorized to transmit in that band for which complete advance 
publication information is received by the ITU’s Radiocommunication Bureau prior to January 1, 2020,
would be required to attenuate their unwanted emissions in the 23.6-24 GHz band from the Commission’s 
existing limit of -43 dBW/4 kHz (4 dBW/200 MHz) by an additional 40 dB (from 4 to                                 
-36 dBW/200 MHz).  Thereafter, new NGSO ISS satellites authorized to transmit in the band for which 
complete advance publication information is received by the ITU’s Radiocommunication Bureau on or 
after January 1, 2020, would be required to attenuate their unwanted emissions in the 23.6-24 GHz band 
to -46 dBW/200 MHz.
235
The Commission also stated that if it adopted proposed footnote US145, then it 
would also amend Section 25.202 to reflect that decision in Part 25 of its rules.  Finally, it noted, inter 
alia, that Iridium is the only non-Federal NGSO ISS licensee currently operating in the 22.55-23.55 GHz 
band and that it appears that Iridium’s ISS links do not exceed the permissible interference criteria of 
Recommendation ITU-R RS.1029 for current passive sensors, and requested comment on how the 
proposed limits should apply to Iridium’s satellites on a going-forward basis.
236
91. Comments.  CORF is the only party to comment on these issues.  CORF states that the 
NGSO ISS links in the 22.55-23.55 GHz band are of special interest to it because this band is near the 
23.6-24 GHz band, which is allocated to the RAS and the EESS.  CORF states that its members are not 
currently aware of any harm from the existing 22.55-23.55 GHz ISS links to RAS and EESS 
observations, and that its “understanding of the WRC-07 Recommendation is that it is not intended to 
apply to existing NGSO constellations.”
237
92. Decision.  We implement WRC-07’s mandatory unwanted emissions limits in the 
23.6-24 GHz band for all new NGSO ISS systems that will operate in the 22.55-23.55 GHz band.
238
  We 
codify this decision by adding footnote US145 to the Allocation Table and by amending Section 25.202 
to reflect the text of footnote US145 in Part 25 of the Commission’s rules.

WRC-07 NPRM, 27 FCC Rcd at 14643, para. 114.  As shown in n.232, supra, an unwanted emissions limit 
of -43 dBW/4 kHz is equivalent to an unwanted emissions limit of approximately 4 dBW/200 MHz.  For authorized 
bandwidths larger than 20 megahertz, additional attenuation of unwanted emissions would be required.

4. Fixed Stations in the 31-31.3 GHz Band
93. Background.  In the U.S. Table, the 31-31.3 GHz band is allocated to the fixed service 
(FS) and mobile service (MS) on a primary basis for non-Federal use
240
and this frequency band is 
licensed pursuant to Part 101 Subpart L of the Commission’s rules – Local Multipoint Distribution 
Service (LMDS).
241
  The adjacent 31.3-31.8 GHz band is allocated to the Earth exploration-satellite 
service (EESS) (passive), radio astronomy service, and space research service (passive) on a primary 
basis, and per footnote US246, “no station shall be authorized to transmit” in this band.
94. In Resolution 750, WRC-07 adopted a mandatory unwanted emissions limit of -38 dBW 
in any 100 megahertz (-38 dBW/100 MHz) of the 31.3-31.5 GHz EESS (passive) band for FS stations 
that operate in the 31-31.3 GHz band and are brought into use after January 1, 2012.
242
  NTIA 
recommends that the Commission adopt WRC-07’s mandatory unwanted emissions limit for fixed 
stations transmitting in the 31-31.3 GHz band.
243
95. Proposal.  In the WRC-07 NPRM, the Commission noted that WRC-07’s mandatory 
unwanted emissions limit of -38 dBW/100 MHz was chosen because EESS (passive) systems in the 
31.3-31.5 GHz EESS (passive) band need to operate in the entire 200 megahertz bandwidth and cannot 
implement a guardband at the lower edge of the band.
244
  The Commission also observed that if 
WRC-07’s unwanted emissions limit is adopted, fixed stations transmitting in the 31-31.3 GHz band 
would be required to attenuate their unwanted emissions in the 31.3-31.5 GHz EESS (passive) band as 
follows:  By an additional 15 dB (from -23 to -38 dBW/100 MHz) for stations in the 31-31.075 GHz band
(lower LMDS Block B); up to an additional 41 dB (from 3 to -38 dBW/100 MHz) for stations in the 
31.075-31.225 GHz band (LMDS Block A); and up to an additional 61 dB (from 23 to                               
-38 dBW/100 MHz) for stations in the 31.225-31.3 GHz band (upper LMDS Block B).
245
96. The Commission stated that adoption of WRC-07’s mandatory unwanted emissions limit 
for fixed stations transmitting in the 31-31.3 GHz band may be unnecessary to satisfy the operational 
requirements of EESS (passive) systems in ITU Region 2, because unlike in ITU Regions 1 and 3, no 
station can be authorized to transmit in the 31.5-31.8 GHz band in Region 2.
246
  Accordingly, the 
                                                     
240
The 31-31.3 GHz band is also allocated to the standard frequency and time signal-satellite service 
(space-to-Earth) on a secondary basis for Federal and non-Federal use.  Footnote US342 states that, in making 
assignments to stations of other services to which the 31.2-31.3 GHz sub-band is allocated, all practicable steps shall 
be taken to protect the radio astronomy service from harmful interference.  Footnote US211 states that in the 
31-31.3 GHz band, applicants for airborne or space station assignments are urged to take all practicable steps to 
protect radio astronomy observations in adjacent bands from harmful interference.
241
In 1996, the Commission designated the 27.5-28.35 and 29.1-29.25 GHz (limited to transmissions in the 
hub-to-subscriber direction) bands for use by LMDS systems, and in 1997, designated the 31-31.3 GHz band for 
LMDS use.  In 1998, the Commission finalized the LMDS rules and auctioned this spectrum (see Auction 17) as 
Block A (27.5-28.35, 29.1-29.25, and 31.075-31.225 GHz) and Block B (31-31.075 and 31.225-31.3 GHz).  These 
actions were taken in CC Docket No. 92-297.  The rules are codified in 47 C.F.R. Part 101 Subpart L – Local 
Multipoint Distribution Service.
242
See ITU Resolution 750, Table 1-1.  This limit does not apply to such stations that have been authorized prior to 
January 1, 2012.  Id.

246
WRC-07 NPRM, 27 FCC Rcd at 14646-47, para. 125.  Because the EESS (passive) band is wider in the United 
States (and the rest of ITU Region 2) than it is in ITU Regions 1 and 3, the Commission anticipated that EESS 
systems would be capable of accepting a higher level of unwanted emissions from Commission-licensed fixed 
stations in the adjacent 31-31.3 GHz band than the WRC-07 Final Acts permit. See id.
Federal Communications Commission FCC 15-50
40
Commission proposed to urge licensees of fixed stations in the 31-31.3 GHz band to limit the maximum 
elevation angle of the antenna main beam to 20° and employ automatic transmitter power control (ATPC) 
to limit the power of the stations’ unwanted emissions in the 31.3-31.8 MHz band by adding footnote 
NG60 to the Allocation Table.
247
  The Commission further stated that if it adopted proposed footnote 
NG60, it would also amend Section 101.111 to reflect that decision in Part 101 of the Commission’s 
rules.
248
97. In making this proposal, the Commission stated that it was aware that ITU 
Resolution 750 states that long-term protection of EESS (passive) sensors in the 31.3-31.5 GHz and other 
bands is vital to weather prediction and disaster management.
249
  The Commission solicited comment on 
whether it should adopt WRC-07’s mandatory unwanted emissions limit for the 31-31.3 GHz band or, 
alternatively, the Commission’s widely-used unwanted emissions limit, which for comparison purposes 
can be stated as -23 dBW/100 MHz.
250
  The Commission requested comment on whether there are other 
mitigation techniques which would be less burdensome to FS licensees and whether it should limit the 
non-Federal MS allocation in the 31-31.3 GHz band to the mobile service except aeronautical mobile 
service (i.e., delete the unused aeronautical mobile service allocation).
251
98. Comments.  CORF is the only party to comment on this issue.  CORF supports adoption 
of the ITU limit.  It opposes the Commission’s alternative proposal because it would permit higher levels 
of unwanted emissions in the 31.3-31.8 GHz band (i.e., -23 dBW/100 MHz, which is 15 dB higher than 
the ITU limit of -38 dBW/100 MHz).
252
CORF argues that such a large increase in unwanted emissions is 
likely to harm passive service observations in the 31.3-31.8 GHz band.  Furthermore, CORF contends that 
Resolution 750 reflects the understanding that relaxation of this ITU limit would harm worldwide efforts 
to provide reliable quantitative atmospheric, oceanic, and land measurements.  CORF further notes that 
although ITU Resolution 750 is crafted around the EESS (passive) service, the 31.3-31.8 GHz band is 
also an important RAS band that is used in determining the structure and evolution of the early universe.
99. Decision.  We adopt WRC-07’s mandatory unwanted emissions limit for new fixed 
stations transmitting in the 31-31.3 GHz band.  To ensure that equipment meeting this new requirement is 
designed, authorized, and manufactured in an orderly manner, we delay this rule from taking effect until 
three years from the effective date of this Report and Order.  As such, this rule will not apply to 
previously constructed facilities or to new facilities authorized prior to that date.  We codify our decision

Id. The Commission noted that the ITU Radio Regulations permit non-conforming operations on a non-
interference basis.  Therefore, for the United States to remain in compliance with its ITU treaty obligations without 
adopting WRC-07's mandatory unwanted emission limits for any radio service and frequency band, the Commission 
must determine that non-Federal stations operating in accordance the Commission’s rules will not cause harmful 
interference to passive sensors operating in accordance with the International Table and other provisions of the ITU 
Radio Regulations.  See ARINC v. FCC, 928 F.2d 428, 443-44 (D.C. Cir., 1991). See also Cable and Wireless v. 
FCC, 166 F.3d 1224, 1230 (D.C. Cir., 1999); Katel Limited Liability Co. v. AT&T, 607 F.3d 60, 67 (2

Specifically, the Commission solicited comment on whether it should adopt following emissions limit: For all 
new stations in the 31-31.3 GHz band, the power of any emissions in any 1 megahertz of the 31.3-31.8 GHz band 
shall be attenuated below the transmitter power (P) within the licensed bands of operation, in watts, by a factor of 
not less than 43 + 10 log (P) dB (-43 dBW/MHz), which is equivalent to -23 dBW/100 MHz.

1. VHF Maritime Mobile Band (156-162 MHz)
100. In this section, we implement our proposed actions for the VHF maritime mobile band 
(156-162 MHz),
254
except that, based on our review of the NTIA WRC-12 Implementation 
Recommendations, we: 1) decline to adopt two of the proposed changes, as discussed below; and 2)

101. In this sub-section, we adopt the proposals regarding this band that the Commission made 
in the WRC-07 NPRM, except as described below.
256
  First, we amend the U.S. Table by: 1) dividing the 
156.2475-156.7625 MHz band into three bands (156.2475-156.5125 MHz, 156.5125-156.5375 MHz, and 
156.5375-156.7625 MHz); 2) allocating the new 156.5125-156.5375 MHz band (channel 70 with the 
center frequency 156.525 MHz) to the MMS on a primary basis for Federal and non-Federal use;
3) restricting the use of the MMS allocation in the 156.5125-156.5375 MHz band to distress, urgency, 
safety, and calling via digital selective calling (DSC); and 4) maintaining the existing primary MSS 
allocation for non-Federal use in the 156.2475-156.5125 MHz and 156.5375-156.7625 MHz bands.
102. Second, we allocate the 156.4875-156.5125 MHz and 156.5375-156.5625 MHz bands 
(50 kilohertz in total) to the fixed and land mobile services on a primary basis for non-Federal use in 
VHF Public Coast Station Areas (VPCAs) 10-42.
257
  In making these allocations, we require that the use 
of these bands by the fixed and land mobile services not cause harmful interference to, nor claim

protection from, the maritime mobile VHF radiocommunication service.  We codify these decisions by 
adding footnote US227 to the Allocation Table.
103. Third, we make the frequencies 156.525 MHz (channel 70) and 156.800 MHz 
(channel 16) available for search and rescue (SAR) operations that involve manned space vehicles by 
adding references to RR 5.111 in the bands within the U.S. Table that contain these frequencies, i.e., the 
156.5125-156.5375 MHz and 156.7625-156.8375 MHz bands.
104. Fourth, we re-insert RR 5.226 (previously numbered as RR 5.227) into the U.S. Table 
and delete footnote US226.  Fifth, we correct two grammatical/typographical errors in the text of NG117 
and renumber that footnote as NG22.
258
105. Sixth, we simplify the U.S. Table by combining the text from footnotes US77 (which 
specified that certain channels could be assigned to Federal stations in the MMS) and US106 (which 
specified the frequency to be used for environmental communications) and number the resultant footnote 
as US52.  We also permit aircraft stations to use the frequency 156.3 MHz for search and rescue 
operations and other safety-related communications.  However, based on our review of the NTIA 
WRC-12 Implementation Recommendations, we decline to adopt two of the proposed changes in new 
footnote US52 because those modifications would be inconsistent with NTIA’s recommendations.  
Specifically, we decline to adopt proposed paragraph (c), which pertains to MMS use of 156.775 (channel 
75) and 156.825 MHz (channel 76), because WRC-12 designated these frequencies for AIS use.  We also 
decline to adopt proposed paragraph (a), which would have limited Federal use of the frequency 
156.375 MHz to the Lower Mississippi River.  In the next sub-section, we address NTIA’s recommended 
restrictions on AIS operations and codify our decision in new footnote US52.
b. Extending Automatic Identification System (AIS) Capabilities
106. Background.  In the U.S. Table, the two existing AIS bands (AIS 1 at 
161.9625-161.9875 MHz with center frequency 161.975 MHz and AIS 2 at 162.0125-162.0375 MHz with 
center frequency 162.025 MHz) are allocated to the MMS on a primary basis for Federal and non-Federal 
use.  AIS is a maritime navigation safety communications system standardized by the ITU and adopted by 
the International Maritime Organization.
259
  Footnote US228 specifies that the use of these bands is 
restricted to AIS emissions only, except that grandfathered non-Federal stations may continue to use the 
AIS 1 band for non-AIS purposes on a primary basis for various periods of time.
260
107. WRC-07 adopted RR 5.227A, which stated that the AIS 1 and AIS 2 bands are also 
allocated to the mobile-satellite service (MSS) (Earth-to-space) on a secondary basis for the reception of 
AIS emissions from stations operating in the MMS.
261
  In 2009, the International Maritime Organization 
(IMO) modified the format of AIS Class A position report messages to add a distress indicator in the 
                                                     
258
Specifically, we replace the phrases “frequency 156.050 and 156.175 MHz” and “port operating” with the 
phrases “frequencies 156.050 and 156.175 MHz” and “port operations,” respectively.
259
47 C.F.R. § 80.5.
260
On March 31, 2015, Commission staff conducted a ULS search of the AIS 1 band and found that two site-based 
private land mobile radio licensees are the only non-AIS operations currently authorized to transmit in the band.  
Both operate under the grandfathering provisions of footnote US228.  Frontier Refining LLC is authorized to 
operate a mobile relay station in Cheyenne, Wyoming.  See call sign WNQQ375 (expires on Sept. 4, 2021).  The 
State of Arizona is authorized to operate 3 control stations at fixed locations, 5 control stations at temporary 
locations statewide, and 300 mobile units statewide.  See call signs WPGA967, WPGA968, WPGA969, and 
WPGA970 (all of which expire on Nov. 30, 2024).
261
While AIS was designed as a terrestrial system, it was later found that AIS emissions from ship stations could be 
received by space stations in the MSS.  For background, see “Satellite AIS – Developing Technology or Existing 
Capability?” available at http://ro.uow.edu.au/cgi/viewcontent.cgi?article=1543&context=lawpapers.

262
  To support maritime safety requirements and to recognize this IMO decision, as 
well as to support the safety aspect of AIS use by search and rescue aircraft, the United States proposed 
that WRC-12 allocate the AIS 1 and AIS 2 bands to the MSS (Earth-to-space) and the aeronautical mobile 
(off-route) service (AM(OR)S) on a primary and co-equal basis with the MMS in all Regions.
263
  As part 
of its proposal, the U.S. also recommended that: 1) use of these bands by the MMS and MSS (Earth-to-
space) be restricted to AIS emissions; 2) use of these bands by the AM(OR)S be restricted to AIS 
emissions from search and rescue (SAR) aircraft; and 3) AIS operations “shall not constrain the operation 
of stations in services allocated in the adjacent bands.”
264
108. WRC-12 adopted the U.S. proposals with a couple of minor differences.  First, the use 
restrictions for the AIS 1 and AIS 2 bands in RR 5.228C – which limit use of the MMS and MSS (Earth-
to-space) allocations to AIS operations only and of the AM(OR)S allocation to AIS emissions from SAR 
aircraft – are worded slightly different than the U.S. proposals.
265
  Second, WRC-12 adopted a 
grandfathering clause for fixed and mobile services use of the AIS 1 and AIS 2 bands in RR 5.228D that 
the U.S. did not propose.
266
  Specifically, RR 5.228D states that the AIS 1 and AIS 2 bands may continue 
to be used by the fixed and mobile services on a primary basis until January 1, 2025, at which time these 
allocations will no longer be valid.
267
109. Proposal.  In the WRC-07 NPRM, the Commission proposed to add RR 5.227A to the 
AIS 1 and AIS 2 bands in the U.S. Table, but emphasized the secondary status of satellite operations in 
these bands.
268
  It also proposed to update footnote US228 by removing paragraph (c), which specifies a
now-passed March 2, 2011 sunset date for certain non-Federal geographical operations, and renumbering
the footnote as US228D.

See IMO REPORT OF THE SUB-COMMITTEE ON SAFETY OFNAVIGATION ON ITS FIFTY-FIFTH SESSION,
NAV 55/21/Add.1, Oct. 22, 2009, at 51 (available at http://www.srs.sg/docs/default-source/reports-of-sub-
committee-meetings/nav55-21-add1.pdf?sfvrsn=2).
263
As a consequence of its proposal to allocate these bands to the MSS (Earth-to-space) on a primary basis, the U.S. 
also proposed that RR 5.227A be removed from the International Table.  See U.S. Proposals for WRC-12, First 
Tranche, Agenda Item 1.10.
264
In support of its proposal, the U.S. stated that IMO Resolution MSC 74(69) required that AIS “...improve the
safety of navigation by assisting in the efficient navigation of ships, protection of the environment, and operation
of Vessel Traffic Services (VTS)” and that modifying the Radio Regulations to reflect the AIS frequencies “ i s  
critical to search and rescue, safety of navigation, and the safe movement and tracking of vessels, which are vital
to the future of maritime safety.”  It further claimed that the proposal “specifically addresses the need to recognize
the safety aspect of AIS use by search and rescue aircraft authorized by Appendix 18 of the Radio Regulations 
and ITU-R Recommendation M.1371-3, and recognizes the decision by the [IMO] to include a distress indicator
in the navigation status field of AIS Class A position report messages.”  The U.S. specified use restrictions for the 
AIS 1 and AIS 2 bands in two footnotes, 5.A01 and 5.A02.  Id.
265
Specifically, WRC-12 combined the text from the two footnotes that the United States proposed (5.A01 and 
5.A02) and simplified the resultant text.  In addition, WRC-12 did not adopt the U.S.’s proposed phrase “operating 
in accordance with Appendix 18,” pertaining to SAR aircraft operations, and decided that AIS operations in these 
bands “shall not constrain the development and use of the fixed and mobile services operating in the adjacent 
frequency bands” (whereas the U.S. proposed “shall not constrain operation of stations in services allocated in the 
adjacent frequency bands”).
266
See WRC-12 Final Acts at p. 19 (RR 5.228C and RR 5.228D).
267
RR 5.228D also states that, inter alia, administrations are encouraged to make all practicable efforts to 
discontinue the use of the AIS 1 and AIS 2 bands by the fixed and mobile services prior to the transition date.  Id.
268
In particular, the Commission stated that licensees must be prepared to accept any interference to the reception of 
mobile signals in the AIS 1 and AIS 2 bands from the operations of adjacent-band terrestrial services operating in 
accordance with the terms of their licenses.  WRC-07 NPRM, 27 FCC Rcd at 14617, para. 41.

110. The Commission also solicited comment in the WRC-07 NPRM on whether it should 
implement the WRC-12 allocation decisions with regard to the AIS 1 and AIS 2 bands – i.e., the 
modifications designed to promote maritime safety interests.
269
It did not receive any comments that 
addressed this issue.  However, we note that the NTIA WRC-12 Implementation Recommendations do 
address this issue.
270
  First, NTIA recommends that we implement the WRC-12 Final Acts by allocating 
the AIS 1 and AIS 2 bands to the AM(OR)S and MSS (Earth-to-space) on a primary basis for Federal and 
non-Federal use, that use of these bands by the MMS and the MSS (Earth-to-space) be restricted to AIS 
emissions only, and that use of these bands by the AM(OR)S be more specifically restricted to AIS 
emissions from search and rescue aircraft.
271
  Second, NTIA recommends that we add references to 
RR 5.228C and RR 5.228D in the U.S. Table.  Third, NTIA recommends that we extend the sunset date 
for the two licensees that operate non-AIS equipment in the AIS 1 band from March 2, 2024 to January 1,
2025.
272
  Fourth, NTIA recommends that we combine the text from revised footnote US228 with the text 
from its proposed footnote US[replace US52/55] along with new text that pertains to other bands.
273
111. Decision.  Based on NTIA’s recommendations, we implement the WRC-12 Final Acts in 
the two existing AIS bands as follows.  First, consistent with both the WRC-07 NPRM and with the U.S. 
Proposals for WRC-12, we allocate the AIS 1 and AIS 2 bands to the AM(OR)S and MSS 
(Earth-to-space) on a primary and co-equal basis with the MMS for Federal and non-Federal use, limited 
to the transmission of AIS emissions, and add a reference to RR 5.228C in the U.S. Table.  This action 
provides the allocations that are necessary to support maritime safety requirements.  Specifically, the 
primary AM(OR)S and MSS (Earth-to-space) allocations support the IMO’s decision to include a distress 
alert notification within AIS Class A position report messages.
112. Second, we revise the text of footnote US228 by applying the existing MMS restriction to 
AIS emissions to the new MSS (Earth-to-space) allocation.
274
  We also restrict the use of these 
frequencies by the AM(OR)S to AIS emissions from search and rescue aircraft operations.  We also 
                                                     
269
Id.
270
See NTIA WRC-12 Implementation Recommendations at p. 25, US[replace US52/55].  As background, we note 
that there is a significant Federal interest in the AIS 1 and AIS 2 bands.  In September 2008, the Commission 
adopted additional measures for domestic implementation of AIS.  Amendment of the Commission’s Rules 
Regarding Maritime Automatic Identification Systems, WT Docket No. 04-344, Second Report and Order, 23 FCC 
Rcd 13711, para. 1 (2008) (AIS 2nd R&O); Erratum, 24 FCC Rcd 3241 (2009).  With regard to this proceeding, the 
Commission’s most significant decisions in that Order were to designate the 162.0125-162.0375 MHz band for 
exclusive AIS use throughout the Nation and to determine that only Federal entities can operate AIS base stations.  
See AIS 2nd R&O, 23 FCC Rcd at 13712, para. 1.  In addition, in accordance with the Maritime Transportation 
Security Act, the Commission specified that the U.S. Coast Guard regulates AIS carriage requirements for 
non-Federal ships.  These requirements are codified at 33 C.F.R. §§ 164.46, 401.20.  See 47 C.F.R. § 80.393.
271
See NTIA WRC-12 Implementation Recommendations at p.12 (for U.S. Table entries) and p.25 (for 
recommended footnote US[replace US52/55]).
272
We note that recommended footnote US[replace US52/55] includes the following sentence: “AIS 2 may continue 
to be used by non-federal fixed and mobile services until 1 January 2025, at which time this fixed and mobile 
service allocation is no longer valid.”  Because there are no grandfathered operations authorized in the AIS 2 band, 
we believe that NTIA intended to recommend that this grandfathering provision apply to the AIS 1 band.
273
The new text that NTIA recommends pertains to the 156.7625-156.7875 MHz (AIS 3) and 156.8125-156.8375 
MHz (AIS 4) bands, which we seek comment on in the WRC-12 Notice.  See paras. 198-205, infra.
274
Specifically, the pertinent part of the opening sentence in footnote US228 reads as follows: “The use of the bands 
161.9625-161.9875 MHz (AIS 1 with center frequency 161.975 MHz) and 162.0125-162.0375 MHz (AIS 2 with 
center frequency 162.025 MHz) by the maritime mobile service is restricted to Automatic Identification Systems 
(AIS)...”
Federal Communications Commission FCC 15-50
45
further simplify the grandfathering text that is currently in footnote US228.
275
  In doing so, we retain the 
existing March 2, 2024 sunset date by which all non-AIS operations must cease operations in the AIS 1 
band because RR 5.228D encourages us “to make all practicable efforts to discontinue the use of these 
bands by the fixed and mobile services prior to the transition date.”  We place the revised text of US228 
into new footnote US52 (discussed above in paragraph 105) as new paragraph (a).
276
  Finally, we decline 
to add a reference to RR 5.228D in the U.S. Table. We do not need to list this international footnote in 
the U.S. Table because paragraph (a) of new footnote US52 will codify our decision to grandfather the 
only non-AIS uses in these bands.
113. We also update Section 80.371(c) of our rules by removing the second and last sentences
from note 3 (which conveys the same now-obsolete grandfathering information that was listed in 
paragraphs (a) and (c) of footnote US228). See Appendix D for the text of footnote US52 and 
Section 87.371(c).
114. Table 2, below, depicts the AIS 1 and AIS 2 bands as they currently exist in U.S. Table,
and as we have amended them herein.  In the WRC-12 Notice, below, we seek comment on the remainder 
of NTIA’s recommendations that pertain to the VHF maritime mobile band.

2. Additional Federal Coordination Areas in the 17.7-20.2 GHz Range
115. Background.  In this section, we address NTIA’s request for new coordination areas in 
the frequency bands that comprise the 17.7-20.2 GHz range and its effect on non-Federal terrestrial users
in the 17.7-19.7 GHz range.
278
  As background, the frequency bands that comprise the smaller 
17.8-20.2 GHz range are allocated to the fixed-satellite service (FSS) on a primary basis for Federal use, 
restricted to space-to-Earth transmissions (downlinks).  In addition, non-Federal fixed stations operate 
throughout the 17.7-19.7 GHz range. The 17.7-17.8 GHz, 17.8-18.3 GHz, and 19.3-19.7 GHz bands 
                                                     
275
In n.260, supra, we described the two licensees currently operating non-AIS equipment in the AIS 1 band.  Based 
on this review, we revise the grandfathering text in footnote US228 to read as follows: Frequencies in the AIS 1 
band may continue to be used by non-Federal base, fixed, and land mobile stations until March 2, 2024.
276
Consequently, we remove footnote US228 from the Allocation Table.
277
See paras. 198-205, infra.
278
The 17.7-19.7 GHz range is displayed as six discrete frequency bands in the non-Federal Table.  In the Federal 
Table, this range is displayed as four frequency bands (which also encompass frequencies from 19.7 GHz to 
20.2 GHz).
Federal Communications Commission FCC 15-50
46
(18 GHz FS bands) are allocated to the fixed service (FS) on a primary basis for non-Federal use.
279
Footnote NG144 provides for continued operations of previously-licensed (i.e., grandfathers incumbent)
fixed stations in the 18.3-19.3 GHz range, and also grandfathers incumbent fixed stations operating under 
an older band plan in the 18 GHz FS bands (specifically, wide-band FS operations in the 17.7-17.8 GHz, 
17.8-18.3 GHz, and 19.3-19.7 GHz bands).
116. While the general practice is to coordinate all operations in Federal/non-Federal shared 
bands with NTIA, the Commission currently coordinates only those non-Federal terrestrial applications in 
the 17.7-19.7 GHz range that are within the Denver, Colorado and Washington, D.C. areas.  This 
coordination requirement is further limited in the 17.7-17.8 GHz band, by the terms of footnote US401, to 
FS applications that support Multichannel Video Programming Distributor (MVPD) operations.  These 
coordination areas are defined in Section 1.924(e) for Part 101 applicants, in Section 74.32 for Television 
Broadcast Auxiliary Station applicants, and in Section 78.19(f) for Cable Television Relay Service 
(CARS) applicants.
280
  NTIA requests that we extend this coordination requirement to San Miguel, 
California and Guam, stating that these modifications would serve the purpose of advancing, supporting, 
and accommodating the national defense.
281
117. Proposal.  In the WRC-07 NPRM, the Commission proposed to amend footnote US401 
and Sections 1.924(e), 74.32, and 78.19(f) of the Commission’s rules. By doing so, we would add the 
coordination areas requested by NTIA, and update our rules to remove an unused area near Denver that 
could be used by CARS and otherwise more accurately reflect the limited areas where the Federal 
coordination requirement is now in place.
282
  The Commission discussed the proposed locations, noted 
that NTIA had stated that in virtually all of the limited number of cases where interference was predicted 
the Federal Government worked directly with the applicant to develop a plan to mitigate interference and 
satisfy the applicant’s communications requirements with little or no impact on the applicant, and 
tentatively concluded that the public interest justified the additional protected coordination areas.
283
  The 
Commission also noted that there is a longstanding agreement between the Commission and NTIA that 
only a limited number of sites for Federal receiving earth stations will be protected from harmful 
interference in the 17.8-20.2 GHz range and tentatively found that no additional primary Federal earth 
station sites beyond the two being considered in this proceeding should be authorized in the 17.8-18.3 
GHz and 19.3-19.7 GHz bands.
284
  The Commission also proposed to amend the text of the rules to bring 
better consistency between them and to also update them.
285
  This would help preserve non-Federal FS 
use of these frequencies.  In addition, the Commission proposed to update footnote NG144 and to 
renumber it as US139.
286
  It sought comment on whether the coordination requirements for MVPD 
operations in Section 74.32, and references in Section 1.924 to MVPD operations pursuant to Parts 74 
and 78, are still relevant, and, if not, whether they should be removed from the Commission’s rules.
287
                                                     
279
The 17.7-17.8 GHz band (Earth-to-space) and the 18.3-19.7 GHz range (space-to-Earth) are allocated to the FSS 
on a primary basis for non-Federal use.  The 18.6-18.8 GHz band is also allocated to the Earth exploration-satellite 
service (passive) and space research service (passive) on a primary basis for Federal and non-Federal use.

118. Comments.  Boeing and Comsearch commented on these issues.  Boeing has no objection 
to the proposal to include two additional two sites within the coordination requirements for the 
17.7-19.7 GHz range and supports our tentative conclusion regarding no additional coordination areas.
288
119. Comsearch does not explicitly object to our proposal, although it suggests that the 
addition of new coordination areas will serve to discourage future non-Federal FS applicants from 
applying for frequencies in the 18 GHz FS bands and, ultimately, will suppress FS use.
289
  Comsearch 
says that we can promote more efficient use of this spectrum by seeking a commitment from DOD to 
respond to coordination requests in a “reasonable time frame” (which it suggests as 30 days), and by 
allowing for conditional authorization of applications that “include evidence of successful pre-clearance 
from DOD.”
290
120. Decision.  We adopt our proposal to add the San Miguel, California and Guam 
coordination areas to the Allocation Table and to Sections 1.924(e), 74.32, and 78.19(f) of the 
Commission’s rules.  We also adopt our proposal to amend footnote US334 by limiting the primary 
allocation status of Federal earth stations to the Denver, Washington, DC, San Miguel, and Guam 
coordination areas; however, on our own motion, we apply these geographic restrictions across the entire 
17.8-20.2 GHz range (instead of the just 17.8-18.3 GHz and 19.3-19.7 GHz bands).
291
  In taking this 
action, we do not preclude the consideration of a limited number of future Federal earth stations that
would support critical national security requirements.
292
  We expect that NTIA will carefully coordinate 
any future sites with the Commission to ensure minimal impact to fixed stations.
121. In order to simplify and clarify our decision in the Allocation Table, we move the 
coordination requirement for fixed stations that support MVPD operations in the 17.7-17.8 GHz band 
from footnote US401 to US334.  By this action, we require that if the station or proposed station is 
located in whole or in part within the Denver, Washington, DC, San Miguel, or Guam coordination area, 
any application for a new station license to provide MVPD operations in the 17.7-17.8 GHz band or to 
operate in the 17.8-19.7 GHz band for any service, or for modification of an existing station license in 
these bands that would change the frequency, power, emission, modulation, polarization, antenna height 
or directivity, or location of such a station, must be coordinated with NTIA before an authorization will 
be issued.  We are convinced that this action is necessary to support important national defense interests, 
as described by NTIA.  See Appendix D for the revised text of footnote US334.
122. We decline to make any of the coordination and authorization process changes suggested 
by Comsearch.  We agree with NTIA that our existing procedures – in particular the FAS coordination 
process and its established standards for timely review – represent the most appropriate mechanism for 
accommodating the differing Federal/non-Federal interests in the band.
293
Currently, NTIA responds to 
an assignment request through the existing process within nine business days on average, unless the

See Comsearch Comments at 1-7.  Comsearch bases its conclusion on an analysis of existing frequency use in the 
Denver and Washington areas and in other areas that are not subject to coordination.
290
Id. at 4.
291
This clarification reflects the terms of the longstanding agreement with NTIA and is consistent with NTIA’s 
request.  Because of a pending NTIA request that concerns Federal earth stations that operate with non-Federal 
space stations in certain frequency bands, we also clarify that, in the bands between 17.8 GHz and 20.2 GHz, 
Federal earth stations “operating with Federal space stations” shall be authorized on a primary basis only in the four 
areas discussed herein.
292
No other Federal receiving earth stations in the 17.8-20.2 GHz band are planned at this time.
293
See NTIA Fourth Supplement at 1-3.  The FAS process is the existing NTIA process for considering frequency 
assignment requests.  Under existing procedures, there are specific timeframes by which Federal parties must 
respond to such requests.  See id.
Federal Communications Commission FCC 15-50

request is tabled for insufficient information.
294
  The approach we have taken to facilitate Federal/non-
Federal shared use – coordination only in limited geographic areas – allows us to balance the need to 
protect important national priorities with the interest in promoting robust commercial use, and there is 
nothing distinctive about the new San Miguel and Guam areas that would preclude the use of that 
approach there.  While we recognize that parties may logically differentiate between deciding to pursue 
licensing in spectrum requiring coordination with Federal government users versus spectrum that does not 
have such a pre-condition to use, we cannot conclude that such differences warrant a departure from our 
present practices.
295
  We think the most effective way to address Comsearch’s concerns is to work to 
facilitate greater efficiencies within the existing coordination framework.  NTIA notes that “federal 
agencies have worked proactively and directly with fixed station applicants to develop plans to mitigate 
potential interference where predicted,” and suggests that we continue to promote such dialogue at the 
beginning stages of the coordination process.
296
  We agree and encourage prospective licensees to take 
NTIA up on its offer to engage in early discussions with the relevant federal agencies when they may be 
interested in applying for frequencies in the Denver, Washington, San Miguel and Guam coordination 
areas.
123. Finally, we take additional steps, consistent with the proposals set forth in the NPRM, to 
promote efficient use of the 17.7-19.7 GHz range and otherwise improve our existing rules.  Specifically, 
we remove the unused circular area for Morrison, Colorado from Section 78.19(f).  We also move the 
revised text in paragraph (e) of Section 1.924 to paragraph (f).  We amend footnote NG144 and renumber
this footnote as US139.
297
  We also amend Section 101.31(b)(1) by removing the 11.7-12.2 GHz and 
18.3-19.3 GHz bands from the list of frequency bands eligible for conditional authorization.
298
  However, 
we decline to make any changes to the coordination requirements for MVPD operations in Section 74.32, 
or to references in Section 1.924 to MVPD operations pursuant to Parts 74 and 78.  Because no 
commenter addressed the question raised in the NPRM regarding whether these references remain 
relevant, we find no pressing need to address these rules at this time.
3. Rulemaking Proposals That Did Not Receive Any Specific Comments
124. In this section, we consider those proposals that the Commission made in the 
WRC-07 NPRM on which we did not receive any specific comments.  In the WRC-07 NPRM, the 
Commission set forth in detail why it believed each of the proposals discussed below would implement 
                                                     
294
See NTIA Manual, Chapter 9, Section 9.16.2.
295
Although Comsearch suggests that this differentiation has resulted in ‘distinctly suppressed’ use of the band in 
the Denver and Washington areas, the current number of licenses is significantly larger than Comsearch cited in its 
comments.  Furthermore, it appears that many licensees are in fact making productive use of the band 
notwithstanding any potential impediments to its use.
296
See NTIA Fourth Supplement at 2-3.
297
In the WRC-07 NPRM, the Commission stated that the fixed service allocation in the 17.7-18.3 GHz and 
19.3-19.7 GHz bands appeared to obviate the need for the first sentence in NG144 (“Stations authorized as of 
September 9, 1983 to use frequencies in the bands 17.7-18.3 GHz and 19.3-19.7 GHz may, upon proper application, 
continue operations.”), noted that it had previously removed Part 21 from its rules, and proposed to reclassify 
NG144 as a U.S. footnote (because it requires that applications for certain specified modifications to grandfathered 
non-Federal fixed stations be coordinated with NTIA).
298
To simplify and clarify existing paragraph (b)(1) of Section 101.31 of the Commission’s rules, we remove 
unneeded commas, list certain of the “bands” as “band segments,” and list certain of the bands in “GHz” (instead of 
“MHz”).  Because FS use of the 18.3-19.3 GHz band is now limited to grandfathered secondary operations, we 
revise “17,700-19,700” MHz to read “17.700-18.300, 19.300-19.700” GHz to fully implement our decision.  With 
regard to the 11,700-12,200 MHz band, we note that the transition period has concluded, that the FS allocation was 
previously removed from the Allocation Table, and that there are no call signs in ULS that authorize the use of this 
band.  See Appendix D for the revised text of Section 101.31(b)(1).
Federal Communications Commission FCC 15-50

important U.S. policy goals and serve the public interest.  As there is nothing in the record to give us 
cause to revise or reconsider these proposals, we amend Sections 2.1, 2.100, and 2.106 of the 
Commission’s rules as described below.  These rule changes will be codified in the Commission’s rules 
as shown in Appendix D.
a. Active Service Issues
125. Radiolocation Use of 420-450 MHz.  We amend the quiet zone rules in Section 1.924(f) 
to reflect the areas listed in paragraph (a) of footnote US270, limit the applicability of this rule to 
radiolocation systems, and move the revised text from paragraph (f) to paragraph (e).
299
126. Mobile Meter Reading Use of 928-960 MHz.  We amend NG120 by revising “band 
928-960 MHz” and “mobile operations” to “bands 928-929 MHz, 932-932.5 MHz, 941-941.5 MHz, and 
952-960 MHz” and “associated mobile operations,” respectively, and deleting the phrase “as specified in 
47 CFR part 101.”
300
We codify this decision by renumbering the revised text from footnote NG120 as 
NG35 in the Allocation Table.
127. Aeronautical mobile (R) service allocation in the 960-1164 MHz band.  We allocate the 
960-1164 MHz band to the aeronautical mobile (R) service (AM(R)S) on a primary basis for Federal and 
non-Federal use, and restrict the use of this allocation by adding a reference to RR 5.327A in the 
U.S. Table.
301
  By adding RR 5.327A to the U.S. Table, we are requiring that any AM(R)S systems 
operating in the 960-1164 MHz band do so in accordance with recognized international aeronautical 
standards and with Resolution 417.
302
  In Resolution 417, WRC-12 resolved, inter alia, that any AM(R)S 
systems operating in the 960-1164 MHz band shall meet standards and recommended practices (SARPs)
requirements published in Annex 10 to the Convention on International Civil Aviation; and that 
administrations intending to implement AM(R)S in the 960-1164 MHz band, in order not to cause 
harmful interference to the radionavigation-satellite service in the band 1164-1215 MHz, shall utilize the 
specified criteria. We also remove footnote US400, which is now duplicative of the broader AM(R)S 
allocation, from the Allocation Table.
128. Feeder Link Allocations near 1.4 GHz.  We remove the non-Federal FSS allocations from 
the 1390-1392 MHz and 1430-1432 MHz bands and remove footnote US368 from the list of U.S. 
footnotes.
303
  As we proposed in the WRC-07 NPRM, we also combine the text of footnote US37 and the 
portion of footnote US398 that prohibits airborne and space-to-Earth operations, and number the resulting 
footnote as US79.  In addition, we remove footnotes US37 and US398 from the list of U.S. footnotes and 
revise footnote US74 to remove the phrase “(see US368).”
304
129. Radiolocation and Active Sensors in the 9-10 GHz Range.  We upgrade the secondary 
Federal radiolocation service allocation in the 9000-9200 MHz and 9300-9500 MHz bands to primary 
status, allocate the 9300-9500 MHz band to the EESS (active) and the space research service (SRS) 
(active) on a primary basis for Federal use, allocate the 9800-9900 MHz band to the EESS (active) and 
the SRS (active) on a secondary basis for Federal use, and remove footnotes US48 and US51 from the

U.S. Table.
305
  In addition, we add RR 5.473A to the Federal Table in the 9000-9200 MHz band, 
RR 5.475A and RR 5.475B to the Federal Table in the 9300-9500 MHz band, and footnote US476A to 
the U.S. Table in the 9300-9500 MHz band.
130. We allocate the 9300-9500 MHz and 9800-9900 MHz bands to the EESS (active) and 
SRS (active) on a secondary basis for non-Federal use.  We merge the 9500-9800 MHz and 
9800-9900 MHz bands to form the 9500-9900 MHz band in the non-Federal Table.
131. So it is clear that RR 5.475 applies only to the aeronautical radionavigation service, we 
list RR 5.475 to the right of the radionavigation service allocation in the 9300-9500 MHz band of the 
International Table.  To help simplify the U.S. Table, we renumber footnote US66 as US475.
132. Meteorological Satellite Use of 18-18.1 GHz.  We allocate the 18-18.1 GHz band to the 
meteorological satellite-service (space-to-Earth) (MetSat downlink) on a primary basis for Federal and 
non-Federal use.
306
  This action extends the existing 18 GHz MetSat downlink band (18.1-18.3 GHz) from 
200 to 300 megahertz.  We codify this decision by amending footnote US519.
307
b. Passive Service Issues
133. Urging for 1.4 GHz Licensees.  To protect passive sensors in the 1400-1427 MHz band 
from harmful interference, in Resolution 750, WRC-07 adopted non-mandatory unwanted emissions 
levels in the 1400-1427 MHz band for stations in the fixed service (FS) and mobile service (MS) that 
operate in the 1390-1395 MHz and 1427-1435 MHz bands.
308
  As proposed, we urge licensees authorized 
under Parts 27 and 90 of the Commission’s rules that operate fixed point-to-point stations or stations in 
the mobile service in the 1390-1395 MHz and 1427-1435 MHz bands to take all reasonable steps to 
ensure that their stations’ unwanted emissions power does not exceed the unwanted emissions levels 
specified in ITU Resolution 750 in the 1400-1427 MHz band.
309
  We codify this decision by adding 
footnote NG338A to the Allocation Table.  To reflect the text of footnote NG338A in the Part 27 and Part 
90 rules, we amend Section 27.53 by renumbering paragraph (j) as paragraph (j)(1) and adding paragraph 
(j)(2) and amend Section 90.210 by adding paragraph (c)(4).
134. Radio Astronomy Observatories in the 4 and 14 GHz Bands.  As proposed, we update the 
list of radio astronomy stations observing in the 4825-4835 MHz (4 GHz) and 14.47-14.5 GHz (14 GHz) 
bands by revising the text of footnote US203 and renumber it as footnote US113.
310
135. Sharing Criteria in the 36-37 GHz Band.  To protect passive sensors in the 36-37 GHz 
band from harmful interference, WRC-07 adopted Resolution 752, which has mandatory sharing criteria 
for the Earth exploration-satellite service (EESS) (passive), FS, and MS in that band.  As proposed, we 
require that future MS and FS stations operating in the 36-37 GHz band do so in accordance with ITU 
Resolution 752.  We codify this decision by adding footnote US550A to the Allocation Table. However, 
we decline to reflect this decision in Part 101 of the rules at this time because it appears to be more 
appropriate to consider this issue in the context of a service rule proceeding.  We also revise footnote

Resolution 750 also applies to the 1350-1390 MHz, 1395-1400 MHz, and 1435-1452 MHz bands.  The 
Commission does not authorize FS and MS operations in the 1350-1390 MHz band.  We are not applying the 
provisions of Resolution 750 to the Wireless Medical Telemetry Service, which operates in the 1395-1400 MHz and 
1427-1432 MHz bands.  We address Aeronautical Mobile Telemetry (AMT) use of the 1435-1525 MHz band in

US263 by removing the 36-37 GHz band.  We codify this decision by renumbering the revised text of 
footnote US263 as US532 in the Allocation Table.
136. Earth Station Restrictions in the 49.7-50.2 GHz and 50.4-50.9 GHz Band.  To protect 
passive sensors in the 50.2-50.4 GHz band from harmful interference, WRC-07 adopted in Resolution 
750 with mandatory unwanted emissions limits in the 50.2-50.4 GHz band for earth stations in the 
fixed-satellite service (FSS) (Earth-to-space) that transmit in the 49.7-50.2 GHz and 50.4-50.9 GHz 
sub-bands.  As proposed, we require that licensees of these FSS earth stations comply with the mandatory 
unwanted emissions limits in ITU Resolution 750 in the 50.2-50.4 GHz band.
311
  We codify this decision 
in the Commission’s rules by adding footnote US156 to the Allocation Table.  To reflect the text of 
footnote US156 in Part 25 of the Commission’s rules, we amend Section 25.202 by revising paragraph (f) 
to provide for an exception to the general emission limitations and by adding the adopted emission limits 
to new paragraph (j).
137. Fixed Station Restrictions in the 51.4-52.6 GHz Band.  To protect passive sensors in the 
52.6-54.25 GHz band from harmful interference, WRC-07 adopted Resolution 750 with a mandatory 
unwanted emissions limit in the 52.6-54.25 GHz EESS (passive) band for fixed stations that operate in 
the 51.4-52.6 GHz band.  As proposed, we require that future licensees of fixed stations transmitting in 
the 51.4-52.6 GHz band comply with the unwanted emissions limit in ITU Resolution 750 in the 
52.6-54.25 GHz band.
312
  We codify this decision by adding footnote US157 to the Allocation Table. 
However, we decline to reflect this decision in Part 101 of the rules at this time because it appears to be 
more appropriate to consider this issue in the context of a service rule proceeding.
138. Radio Astronomy Observatories in the 81-95 GHz Range.  As proposed, we update 
footnote US388 by removing the Five Colleges Radio Observatory, adding the Heinrich Hertz 
Submillimeter Observatory (located at Mount Graham, Arizona), simplifying the text, and renumbering this 
footnote as US161.
313
  As a result, all non-Federal applications within 150 km of the coordinates of the 
Heinrich Hertz Submillimeter Observatory (32° 42' 06'' N, 109° 53' 28'' W) must be coordinated with NTIA 
to protect radio astronomy observations in the 81-86 GHz, 92-94 GHz, and 94.1-95 GHz bands.
c. Other Matters
139. We amend the definition of two terms currently in Section 2.1 of the rules and update 
Section 2.100 of the rules.
314
  For the definition of Earth exploration-satellite service in Section 2.1, we 
make minor changes so that it agrees with the definition in the ITU Radio Regulations.
315
  For the 
definition of equivalent isotropically radiated power in Section 2.1, we add the parenthetical statement 
“(absolute or isotropic gain).”
140. We amend Section 2.100 of the rules to state that the ITU Radio Regulations, Edition of 
2008, have been incorporated to the extent practicable in Part 2, except that the International Table within 
§ 2.106 has been updated to reflect the ITU Radio Regulations, Edition of 2012.
V. ORDER (WRC-12 ORDER)
141. In this Order, we take several non-substantive, editorial actions to update the 
Commission’s rules.  None of the rule changes discussed in this order require prior notice and an 
opportunity for comment under the Administrative Procedure Act (APA).  Section 553(b)(B) of the APA 
provides exceptions to the notice-and-comment requirements for rulemakings when, among other things,

the agency finds for good cause that the notice and comment procedures are “impracticable, unnecessary, 
or contrary to the public interest” with respect to the rules at issue.  The changes we are making in the 
rules correct minor errors in the Allocation Table, implement revisions adopted in prior Commission 
orders, and otherwise entail non-substantive matters.  As such, they constitute routine, “clean-up” matters 
that entail no substantive decisions of any consequence or significance to industry or the general public.  
Accordingly, we find that it is “unnecessary,” within the meaning of Section 553(b)(B), to provide notice 
and an opportunity for comment before adopting these rule revisions.
142. First, we update the International Table within Section 2.106 of the rules to reflect 
Article 5, Section IV of the ITU Radio Regulations, Edition of 2012, except as described herein.
316
  
Because WRC-12 made substantive changes to RR 5.565, which is currently referenced in the U.S. Table, 
it is necessary for us to create new footnote US565, which replicates the pre-WRC-12 text of this
international footnote.  This action allows us to update the International Table within Section 2.106, while 
maintaining the status quo in the U.S. Table until such time as we can consider any pertinent comments 
that may be filed in response to the WRC-12 Notice.
143. During our preparation of this Order, we discovered several display errors in the 
International Table.  Consistent with past practice, we will not replicate typographical or other errors that 
convey misleading information or could potentially cause reader confusion.
317
Accordingly, we 
incorporate the following corrections and updates in the International Table in Section 2.106 of the 
Commission’s Rules:  First, we remove various references to international footnotes in the Region 1 
Table (i.e., RR 5.72 in the 283.5-415 kHz range, RR 5.101 in the 1810-1850 kHz band, RR 5.272 and/or 
RR 5.273 in the 430-440 MHz range, and RR 5.397 in the 2450-2483.5 MHz band) because WRC-12 
suppressed these footnotes.  Second, we alphabetically list (per the French spelling) the services in the 
Region 3 Table for the 24.25-24.45 GHz band.  We base these corrections and updates upon the format 
specified in the ITU Radio Regulations.
318
144. With regard to international footnotes, we simplify ten of them (5.197A, 5.286AA, 
5.351A, 5.353A, 5.384A, 5.388, 5.389A, 5.389C, 5.444A, and 5.547).  Specifically, we update the 
cross-references to eight ITU Resolutions (Resolutions 75, 114, 222, 223, 224, 225, 413, and 716) in 
these footnotes to the version listed in Volume 3 of the 2012 Edition of the ITU Radio Regulations.
319
  
We add the notation “(FCC)” to the end of the footnotes that we have simplified.  In addition, we add the 
abbreviation “(WRC-12)” to the end of the international footnotes that were added or revised at WRC-12
to signify the source of the current footnote text.
320
  As a result of this action, note 1 of the FCC Online

The International Table within Section 2.106 of the rules is included for informational purposes only, and thus, 
the changes we make to it are non-substantive.  47 C.F.R. § 2.104(a).  For additional background information on the 
Allocation Table, see paras. 5-6, supra.  The minor, editorial differences that are discussed in this Order between 
Article 5, Section IV of the ITU Radio Regulations, Edition of 2012, and the International Table in Section 2.106 of 
the Commission’s Rules will be listed in note 1 to the FCC Online Table of Frequency Allocations, which is 
available at http://www.fcc.gov/oet/spectrum/table/fcctable.pdf.

Although these ten international footnotes contain a “Note by the Secretariat” stating that a subsequent WRC 
updated a Resolution, the 2012 Edition of the ITU Radio Regulations contains only the current version of these 
Resolution(s) (see Volume 3).  In order to assist readers, we revise the text of these international footnotes in 
Section 2.106 to directly list the version that is currently shown in the ITU Radio Regulations.  See Appendix D for 
the complete text of these footnotes.  We have previously made similar revisions to RR 5.345, RR 5.396, and 
RR 5.516B.

145. Second, we reflect in the Allocation Table the reallocation of the 700 MHz D Block for 
use by public safety services.
321
As background, the Middle Class Tax Relief and Job Creation Act of 
2012 established the First Responder Network Authority (FirstNet) to oversee the construction and 
operation of a nationwide public safety broadband network as licensee of both the existing public safety 
broadband spectrum (763-768/793-798 MHz) and the spectrally adjacent 700 MHz D Block spectrum 
(758-763/788-793 MHz).
322
Accordingly, we amend the U.S. Table by revising the upper or lower 
frequency limits of four frequency bands (698-763 MHz, 763-775 MHz, 775-793 MHz, and 
793-805 MHz) to shift the 700 MHz D Block spectrum from the 700 MHz Band Commercial Services 
bands to the 700 MHz Public Safety bands.
323
  See Appendix D where the 698-758 MHz, 758-775 MHz, 
775-788 MHz, and 788-805 MHz bands are now specified in accordance with these revisions.  In 
addition, we amend footnote NG158 by revising the “763-775 MHz and 793-805 MHz” bands to read 
“758-775 MHz and 788-805 MHz,” and renumber revised footnote NG158 as NG34.
146. Third, we revise Section 27.803(b)(4) to reflect two previous Commission actions.
324
  The 
WRC-07 Table Clean-up Order revised footnote US351 to remove the expired grandfathering provision 
which allowed Federal operations in the 1390-1400 MHz band at 17 sites on a fully protected basis, and 
combined the resultant text with footnote US352 in a single new footnote US37 (renumbered as footnote 
US79 in paragraph 128, supra).
325
In the WRC-07 Order, the Commission amended footnote US361 to 
correct the name of a grandfathered site, to remove a different grandfathered site, to simplify the text, and 
(Continued from previous page)                                                           
listed in the ITU Radio Regulations, followed by the notation “(SUP – WRC-12),” we decline to follow this 
convention and will not list these footnotes in Section 2.106.

Prior to the Commission’s action, the 700 MHz Public Safety band (763-775 MHz downlink and 793-805 MHz 
uplink bands) consisted of the following band segments: Broadband segments (763-768/793-798 MHz), guard band 
segments (768-769/798-799 MHz), and narrowband segments (769-775/799-805 MHz).  Thus, the revised 700 MHz 
Commercial Services bands are 698-758/775-788 MHz, and the revised 700 MHz Public Safety bands are
758-775/788-805 MHz.

  We update Section 27.803 to remove paragraph (b)(4)(i) because no

that of Section 27.803(b)(4)(ii) and renumber it as Section 27.803(b)(4).

Commission’s rules

VI. NOTICE OF PROPOSED RULEMAKING (WRC-12 NOTICE)
148. In this WRC-12 Notice of Proposed Rulemaking (WRC-12 Notice), we propose to amend 
Parts 2, 15, 80, 90, 97, and 101 of the Commission’s rules to implement specific allocations from the 
WRC-12 Final Acts that affect frequencies between 8.3 kHz and 3000 GHz, and to update the appropriate 
service rules. These proposals are based on NTIA’s Recommendations for National Implementation of 
the WRC-12 Final Acts, which were submitted to the Commission on March 28, 2013.
329
  NTIA’s 
recommendations are generally based on the U.S. Proposals for WRC-12.  In addition to proposing rules 
to implement specific allocations from the WRC-12 Final Acts, we address several matters that pertain to 
unresolved issues from WRC-07.  We have organized the discussion below to first address those 
allocation issues that pertain to Federal/non-Federal shared bands in ascending frequency order and then 
to address remaining issues, all of which pertain to new Federal-only allocations.
A. Issues Below 490 kHz
1. Passive Systems for Lightning Detection (8.3-11.3 kHz)
149. In this section, we consider WRC-12’s actions that protect passive lightning detection 
systems, which operate within the meteorological aids (MetAids) service.
330
  These long-established, 
passive applications are used by meteorological organizations to provide warnings of extreme weather 
events to a range of organizations and customers including emergency, aviation, defense, and utility 
services, as well as the public.
331
  Lightning detection systems rely on naturally occurring emissions from

We recently modified Part 15 of the Commission’s rules to permit level probing radars to operate on an 
unlicensed basis in the 5925-7250 MHz, 24.05-29 GHz, and 75-85 GHz bands. Amendment of Part 15 of the 
Commission’s Rules To Establish Regulations for Tank Level Probing Radars in the Frequency Band 77-81 GHz, 
ET Docket No. 10-23, Report and Order and Order, 29 FCC Rcd 247 (2014).  Currently, there is a cross-reference 
to “RF Devices (15)” only in the 76-77 GHz band.  Therefore, we revise column 7 of the Allocation Table by adding 
a cross-reference to Part 15 in the remaining bands.  We also add missing cross-references to Part 25 (i.e., “Satellite 
Communications (25)”) in the 6425-6525 MHz and 6525-6700 MHz bands.  See 47 C.F.R. § 25.202(a)(1) (where 
“6.425-6.525” and “6.525-6.7” are listed in the table of frequency bands that are available for use by the fixed-
satellite service under the heading “Earth-to-space (GHz)”). 
328
While we generally do not use these terms when discussing frequency matters, we believe that retaining the terms 
in the Commission’s rules will provide useful historical context.  47 C.F.R. § 2.101.

lightning strikes and there have been past instances of compromised data due to interference from various 
RF emission sources.
332
150. Background.  Prior to WRC-12, the International Table did not include any allocation
below 9 kHz.  Spectrum below 9 kHz was governed by two international footnotes:  RR 5.53 allowed the 
use of this unallocated spectrum conditioned upon the lack of harmful interference to the allocated 
services in the bands above 9 kHz; and RR 5.54 urged administrations conducting scientific research in 
the spectrum to advise other potentially affected administrations in order to provide such research with all 
practicable protection from harmful interference.  The 9-14 kHz band was allocated to the radionavigation 
service (RNS) on a primary basis in all ITU Regions and in the U.S. Table.  We note however that this
RNS allocation is not currently used in the United States.  In the U.S. Table, the entries below 14 kHz 
have generally mirrored the International Table.  In addition, two U.S. footnotes also apply to the 
9-14 kHz band.  Footnote US18 generally limits the use of navigation aids in the 9-14 kHz band (which 
are authorized under the RNS allocation) and other bands to Federal agencies.
333
Footnote US2 authorizes 
power line carrier (PLC) systems to operate in the 9-490 kHz band.
334
151. The United States proposed that WRC-12 allocate the 8.3-9 kHz and 9-11.3 kHz bands to 
the MetAids service on a primary basis in all ITU Regions and make appropriate modifications to 
RR 5.53 and RR 5.54.  Further, the United States proposed to limit the use of these MetAids allocations to 
passive use, and in the 9-11.3 kHz band, to prohibit MetAids stations from claiming protection from those 
RNS stations that were submitted to the ITU for notification prior to the date of entry into force of the 
WRC-12 Final Acts.
335
  In support of this proposal, the United States stated that recent ITU-R studies 
show the optimal frequency for arrival time difference (ATD) measurements is around 9.76 kHz,
336
and 
that Recommendation ITU-R RS.1881 determined that lightning detection systems are optimized with a 
3 kilohertz bandwidth signal from 8.3-11.3 kHz.
337
  The United States also noted that any interference to 
ATD systems in the 8.3-9 kHz band would impact such operations in the 9-11.3 kHz band as well, and 
thus, it is important to protect the full range of the signal to ensure that the ATD systems will be able to 
use their allocated band without interference.
152. Discussion.  WRC-12 adopted the U.S. proposals with minor text changes.
338
  NTIA 
recommends that we implement these WRC-12 allocation changes in the U.S. Table.
339
  Based on this 
                                                     
332
We note that “to avoid interference in certain parts of the world, the centre frequency of a current international 
network of lightning detection stations, which had been [centered] on 9.765625 kHz since 1939, has recently had to 
be moved to 13.733 kHz.”  See Resolution 671 (WRC-07), considering c).
333
More specifically, footnote US18 states that navigation aids are normally operated by the Federal Government in 
the 9-14 kHz, 90-110 kHz, 190-415 kHz, 510-535 kHz, and 2700-2900 MHz bands; however, authorizations may be 
made by the Commission for non-Federal operations in these bands, subject to the conclusion of appropriate 
arrangements between the Commission and the Federal agencies that normally operate these navigation aids and 
upon special showing of need for service which the Federal Government is not yet prepared to render.

The automated ATD system uses the time differences of signal received to derive lighting strike locations.  
Meteorological organizations analyze the data from the ATD system and provide forecasts to assist safety-of-life, 
public safety, and aviation operations.  Id.

operating in the meteorological aids service in the frequency band 9-11.3 kHz,” at Table 1.
338
Specifically, WRC-12 allocated the 8.3-9 kHz and 9-11.3 kHz bands to the MetAids service on a primary basis in 
all ITU Regions, and through its adoption of RR 5.54A limited the use of this allocation to passive use.  RR 5.54A 
also states that, in the 9-11.3 kHz band, MetAids stations shall not claim protection from stations of the RNS 
submitted for notification to the ITU (i.e., Radiocommunication Bureau) prior to January 1, 2013, and that, for 
sharing between MetAids and RNS stations submitted for notification after this date, the most recent version of

recommendation, we propose to allocate the 8.3-9 kHz and 9-11.3 kHz bands to the MetAids service on a 
primary basis for Federal and non-Federal use, and to limit this MetAids allocation to passive use by 
adding RR 5.54A to the U.S. Table.
340
  We believe that lightning detection systems provide a valuable 
public benefit and that the adoption of these proposals would serve the public interest by providing 
interference protection to these passive lightning detection systems, which operate in the MetAids service.  
We request comment on these proposals, noting that there is no current allocated use of the 8.3-11.3 kHz 
band in the United States.
2. Radio Buoys Operating in the 1900-2000 kHz Band
153. In the WRC-07 R&O above, we discussed use of radio buoys by the U.S. commercial 
fishing fleet, we observed that fishing vessels appear to have been using the radio buoys (which were 
approved under the Commission’s Equipment Authorization program pursuant to Part 90 of the rules)
under the faulty assumption that such use is permitted by their Part 80 ship station licenses, and we 
provided a temporary waiver of our rules to allow for radio buoy operations by commercial fishing 
vessels under a ship station license in the 1900-2000 kHz band.  In this WRC-12 Notice we propose to 
amend Part 80 of the Commission’s rules to authorize radio buoy operations in the 1900-2000 kHz band 
under a ship station license.
154. Under our Part 80 rules, a ship station license includes the authority to operate on 
frequencies allocated to the maritime mobile service (MMS) as well as to operate specified types of 
equipment.
341
Section 80.375 of the Commission’s rules lists the carrier frequencies and frequency bands 
that are available for various uses in the maritime radiodetermination service.
342
  We propose to amend 
Section 80.375 to make the 1900-2000 kHz band available to commercial fishing vessels for use by radio 
buoys on the open sea and to include them in the equipment authorized as part of a ship station license.
343
  
We seek comment on these proposals.
155. We propose to adopt technical requirements in Part 80 of the rules for the radio buoys 
based on the existing Part 80 rules and the characteristics of radio buoys that are currently imported 
and/or marketed pursuant to the Part 90 rules.  Specifically, we propose to authorize buoy stations to 
transmit on any frequency in the 1900-2000 kHz band, provided that the output power does not exceed 
10 W and that the antenna height of the buoy station does not exceed 4.6 meters (15 feet) above sea level.  
Next, we propose rules for the use of “sel-call buoys” (i.e., radio buoys that transmit only after receiving a 
(Continued from previous page)                                                           
Recommendation ITU-R RS.1881 should be applied.  In the 8.3-9 kHz band, WRC-12 also adopted two footnotes 
(RR 5.54B, RR 5.54C) that provide for additional allocations in certain countries.  See WRC-12 Final Acts, pp. 5-6.
339
See NTIA WRC-12 Implementation Recommendations at p. 2.
340
In the Order above, we update the International Table to reflect the 2012 ITU Radio Regulations.  As such, the 
text of RR 5.54A (and other international footnotes we discuss herein) is not reprinted in the proposed rules 
appendix.  Such footnotes can instead be found in Appendix D.
341
47 C.F.R. § 80.17(a)(4).  See also Amendment of the Commission’s Rules Concerning Maritime 
Communications, PR Docket No. 92-257, Second Report and Order and Second Further Notice of Proposed Rule 
Making, 12 FCC Rcd 16949, 16978 at para. 54 (1997) (“each applicant for a new ship station license will be 
automatically authorized to operate a marine VHF radio, a single-sideband radio, any type of radar or emergency 
position indicating radio beacon (EPIRB), on-board communications equipment, and satellite communications 
equipment”).  Authorization for other types of equipment must be specifically requested.  
342
For example, Section 80.375(c) lists six assignable radiodetermination frequencies below 500 MHz that are 
“authorized for offshore radiolocation and associated telecommand operations under a ship station license provided” 
inter alia, the station antenna height does not exceed 6 meters (20 feet) above sea level in a buoy station or 6 meters 
above the mast of the ship on which it is installed.  47 C.F.R. § 80.375.

selective calling signal from their associated ship station).
344
  Based on the characteristics of sel-call 
equipment, we propose to authorize ship stations to transmit selective calling signals on all frequencies in 
the 1900-2000 kHz band, provided that the output power does not exceed 10 W and that the station’s 
antenna height not exceed 6 meters (20 feet) above the mast of the ship on which it is installed.  Finally, 
we propose to amend footnote NG92 to provide for radio buoys that cannot be authorized under the 
radiolocation service by allocating the 1900-2000 kHz band to the maritime mobile service on a primary 
basis in Regions 2 and 3, restricted to radio buoy operations on the open sea, and to explicitly state that 
stations in the amateur, maritime mobile, and radiolocation services located in Region 2 will be protected 
from harmful interference only to the extent that such radiation exceeds the level which would be present 
if the offending station were operating in compliance with the technical standards or criteria applicable to 
the service in which it operates.
345
  We have crafted the proposed footnote to restrict operations to the 
open sea based on the areas where radio buoys appear to be in use, and because doing so would provide 
greater protection for amateur stations by excluding radio buoys from “inland waters.”
346
  Parties who 
believe that this geographic area should be extended to include the Chesapeake Bay, Great Lakes, or other 
inland waters should document why such an extension is warranted.  We seek comment on these 
proposals.  See Appendix F for the proposed text of footnote NG92 and Section 80.375(f).
156. We also seek comment on alternative approaches that would accomplish our objective of 
allowing continued radio buoy use by the U.S. high seas fishing fleet.  For example, should we transition 
new radio buoy use to another MF band, and, if so, how would the costs to manufacturers and operators 
relate to any benefits that amateur operators may realize from such a transition?
347
  Should we add the 
1900-2000 kHz band to Section 90.248 of our rules, which already authorizes ocean buoy tracking, rather 
than Section 80.375?
348
  For future radio buoy equipment, would it be beneficial to authorize different 
transmitter output power limits in segments of the 1900-2000 kHz band for operations near the 
                                                     
344
Selective calling is a means of calling in which signals are transmitted in accordance with a prearranged code to 
operate a particular automatic attention device at the station whose attention is sought.  47 C.F.R. § 80.5.  For 
context, see http://map.seafdec.org/downloads/pdf/tuna%20purse%20seine/Tuna%20purse%20seine2.pdf.
345
Under the Commission’s rules, radiodetermination is defined as the determination of the position, velocity, 
and/or other characteristics of an object, or the obtaining of information relating to these parameters, by means of 
the propagation properties of radio waves and radiolocation is defined as radiodetermination used for purposes other 
than those of radionavigation.  Radio direction-finding is defined as radiodetermination using the reception of radio 
waves for the purpose of determining the direction of a station or object.  47 C.F.R. § 2.1(c).  While most radio 
buoys currently operate in the radiolocation service, some also transmit their GPS coordinates, and thus, the 
associated ship station does not necessarily use radio direction-finding to locate these radio buoys.  Our proposal to 
allocate the 1900-2000 kHz band to the maritime mobile service would support the transmission of a radio buoy’s 
GPS coordinates and other data, such as the identification number of the buoy and water temperature.  See, e.g., 
GV-58 GPS buoy system.  We propose to add a note to Section 80.375(f) to specify that such use is permitted.  See 
Appendix F.
346
“Inland waters” means the waters shoreward of the territorial sea baseline.  33 C.F.R. § 2.26.
347
In the U.S. Table, the 1705-1800 kHz band is allocated, inter alia, to the radiolocation and mobile services on a 
primary basis for Federal and non-Federal use.  We note that the upper 50 kilohertz of this band (1750-1800 kHz) is 
lightly used.  It appears that all of the MF radio buoy transmitters currently being marketed are capable of operating 
in the 1750-1800 kHz band.  For example, the marketing material for radio buoy model “KTUS-1L” (FCC ID No. 
XLTKTUS-1L) (for which ITM is the grantee listed) states that “[o]ne frequency is transmitted between the ranges 
of 1605 to 4000 kHz (in USA, 1900-1999.9 kHz).”  See http://www.blueoceantackle.com/radio_buoys.htm. 
348
Users would be required to obtain individual licenses under our Part 90 rules.  This may nevertheless represent a 
better approach than using Part 80, especially considering that the radio buoys are not designed to operate on the 
vessel like the other ships equipment that is addressed in the Part 80 rules.
Federal Communications Commission FCC 15-50

coastline?
349
  Finally, are there any additional considerations we should take into account regarding radio 
buoy use in international waters?
157. We note that, in the context of the WRC-07 proceeding above, ITM requested that the 
Commission expand the frequencies available for radio buoy use, and states that its customers have 
complained that the 1900-2000 kHz band is getting crowded.
350
  Based on our survey of international 
spectrum usage and trends, it appears that the proposed designation of 100 kilohertz of MF spectrum may 
be sufficient for the commercial fishing industry’s requirements.
351
  We therefore seek comment on the 
level of use of the 1900-2000 kHz band for radio buoys, whether additional spectrum is required for radio 
buoys, and if there are specific technical measures that will allow the U.S. commercial fishing fleet to 
make more efficient use of our limited spectrum resources.  We also seek comment on whether we should 
establish a channeling plan or bandwidth limitations for radio buoys as these may provide for more 
efficient use of the limited available spectrum.
158. With regard to equipment authorization, we propose to establish a cutoff date after which 
new applications for equipment authorization of radio buoys must meet the new Part 80 rules in order to 
receive authorization and that radio buoys authorized under Section 90.103(b) prior to that date may 
continue to be sold and marketed, i.e., this equipment would be grandfathered.  We propose to establish 
the cutoff date as six months from the effective date of the Report and Order adopted in response to this
WRC-12 Notice.
352
  We solicit comment on our proposal.
3. Amateur 2200 Meter (135.7-137.8 kHz) and 630 Meter (472-479 kHz) Bands
159. In the WRC-07 R&O, we added a secondary amateur allocation to the 135.7-137.8 kHz 
band (2200 meter band) along with RR 5.67A, which limits amateur stations in the band to a maximum 
radiated power of 1 W equivalent isotropically radiated power (EIRP).
353
  In accordance with WRC-12, 
we now propose to also allocate the 472-479 kHz band (630 meter band) to the amateur service on a 
secondary basis.  We also propose adopting RR 5.80A, which would limit amateur stations located in the 
United States to a maximum radiated power of 5 W EIRP.  We also seek comment on service rules for 
amateur stations in both these bands that will allow the amateur stations to coexist with Power Line 
Carrier (PLC) systems, which operate in these bands.
160. Background.  After concluding that amateur stations may share the 135.7-137.8 kHz band 
with PLC systems, we added a secondary amateur service allocation to the band in the WRC-07 R&O.

349
While such an action might offer additional protection for amateur service operations in the lower portion of the 
1900-2000 kHz band, we would also need to consider the burdens on implementing such an arrangement on the 
commercial fishing industry.
350
See ITM Comments at 2.
351
We note that some buoys now transmit their GPS position to their associated fishing vessel via satellite 
communications, which suggests that the need for additional spectrum for traditional radio buoys may be reduced or 
obviated.  See Marine Star sel-call buoy (SV-1800 Type).  See also “Evolution of Radiobuoys Technology for 
FADS[:] Past, Present and Future,” Marine Instruments presentation, Oct. 2012 (available at http://ebfmtuna-
2012.sciencesconf.org/file/23474).  Other jurisdictions appear to offer similar resources to support radio buoy use.  
For example, New Zealand authorizes radio buoys to operate on 13 frequencies in the 1705-1800 kHz and 
1950-2000 kHz bands with a maximum carrier power of 10 W, a 1 kilohertz bandwidth, and a transmitter tolerance 
of + 100 hertz.  See http://www.rsm.govt.nz/cms/licensees/types-of-licence/general-user-licences/maritime-
purposes.  See also http://www.teleconformity.com/documents/jrr.html and

sel-call buoys).

As discussed in greater detail there, electric utilities operate PLC systems in the 9-490 kHz band for 
communications important to the reliability and security of electric service to the public.
355
  PLC systems 
operate under the provisions of Section 15.113 of the Commission’s rules on an unprotected and 
non-interference basis with respect to authorized radio users.  They are restricted to operating only on 
transmission lines and therefore, in general, do not operate in residential areas.
356
161. WRC-12 allocated the 472-479 kHz band to the amateur service on a secondary basis in 
all ITU Regions (i.e., directly listed “Amateur” in the International Table),
357
but also adopted an 
international footnote that prohibited its use in 27 countries.
358
  WRC-12 also adopted RR 5.80A, which 
limits the maximum equivalent isotropically radiated power EIRP of amateur stations in the 472-479 kHz 
to 1 W, provides that administrations may increase this EIRP limit to 5 W in those portions of their 
territory which are more than 800 km (497 miles) from the borders of 30 specified countries, and 
establishes that amateur stations operating in this band must not cause harmful interference to, nor claim 
protection from, stations of the aeronautical radionavigation service (ARNS).
359
  We note that only a
portion of Alaska is within 800 km of a listed country (the Russian Federation), and thus, the 1 W EIRP 
restriction in the ITU Radio Regulations applies to U.S. amateur stations only in that lightly populated 
area.
162. Prior to WRC-12, the 415-495 kHz band was allocated worldwide in the International 
Table to the maritime mobile service (MMS) on a primary basis and to the ARNS on a secondary basis in 
Regions 2 and 3.  MMS use of the 415-495 kHz band was limited to radiotelegraph (RR 5.79) and ARNS 
use of the 435-495 kHz band was limited to non-directional beacons not employing voice transmission 
(RR 5.80).  Two additional footnotes (R.R 5.79A, RR 5.82) relate to the Navigational Telex (NAVTEX)
service.
360
  However, because all NAVTEX broadcasts in the United States are made on 518 kHz, these 
provisions will have minimal effect on U.S. frequency use.
361
163. In the United States, the 435-495 kHz band is allocated to the MMS on a primary basis 
for Federal and non-Federal use and to the ARNS on a secondary basis for Federal use.  The Commission 
has previously added references to RR 5.79, RR 5.79A, and RR 5.82 in the U.S. Table.  In addition, 
footnote US231 states that aeronautical radiobeacons may be authorized on a secondary basis in the 
435-490 kHz band under specified conditions.  Electric utilities also operate PLC systems on transmission 
lines in the 9-490 kHz band, per footnote US2.
362
  There are no Federal stations authorized to operate in

distribution system) on the Edison Electric Institute’s website (available at 
http://www.eei.org/ourissues/electricitydistribution/Pages/HowWorks.aspx).
357
NTIA made no recommendation with regard to the secondary amateur service allocation in the 472-479 kHz 
band.
358
These countries are listed in new footnote RR 5.80B.
359
The 472-479 kHz band is allocated to the ARNS on a secondary basis in all ITU Regions and on a primary basis 
in the 18 countries/areas listed in RR 5.77.  The protection requirement in RR 5.80A pertains both to primary and 
secondary ARNS operations.
360
NAVTEX is an international automated MF direct-printing service for delivery of navigational and 
meteorological warnings, as well as urgent marine safety information to ships.  WRC-12 revised RR 5.82 to afford 
protection to the NAVTEX service on 490 kHz from amateur service operations.  For the revised text of RR 5.82, 
see Appendix D.

The U.S. Coast Guard states that all NAVTEX broadcasts are made on 518 kHz.

the 472-479 kHz band and there are only three non-Federal coast stations that operate in this band using 
very narrow bandwidths.
363
  Thus, it appears that only 540 hertz of the 7 kilohertz allocated by WRC-12 
to the amateur service in the 630 meter band is currently being used by allocated services in the United 
States.
164. On November 29, 2012, ARRL filed a Petition for Rule Making requesting that the 
Commission allocate the 472-479 kHz band to the amateur service on a secondary basis and amend 
Part 97 to provide for use of this band by the Amateur Radio Service.
364
  ARRL states that technical 
self-training and furtherance of radiocommunications development in the amateur service would be 
greatly enhanced by an allocation in the lower portion of the MF range.  ARRL also states that it has 
sponsored an extensive course of experimentation in the MF spectrum near 500 kHz since 2006, and that 
no reports of interference have been received.
365
  ARRL further states that, given typical antenna 
efficiencies in this frequency range, amateur stations are likely to fall well within the 5 W EIRP limit 
established by WRC-12.
366
165. 472-479 kHz Band Allocation.  We propose to allocate the 472-479 kHz band (630 meter 
band) to the amateur service on a secondary basis.  We also propose to add RR 5.80A to the band, which 
would permit us to allow amateur stations to transmit with powers of up to 5 W EIRP in most areas of the 
United States.  This proposal would bring our allocations for the band into harmony with the international 
allocations.  As with the 135.7-137.8 kHz band, the addition of an amateur allocation to this band would
provide new opportunities for amateur operators to experiment with equipment, techniques, antennas, and 
propagation phenomena but with signals having larger bandwidth and higher power.  The fact that other 
allocated services make little use of the band also supports allowing amateurs to have access to this band.  
We seek comment on these proposals.
166. We are cognizant of the functions served by PLC systems that operate in the 472-479 
kHz band on an unprotected and non-interference basis, such as tripping protection circuits if a downed 
power line or other fault is detected in the power grid. Nevertheless, we propose to add an amateur 
allocation because we are comfortable that amateur radio and utility PLC systems can successfully 
co-exist in the band.  We note that no reports of harmful interference to the allocated radio services or to 
PLC systems from experimental amateur operations have been filed with the Commission or with NTIA.  
We therefore propose to permit amateur operations in this 472-479 kHz band in a manner that allows for 
shared use with PLC systems.  We seek comment generally on the sharing of the 472-479 kHz band 
between PLC systems and the amateur service.
                                                     
363
Section 80.357(b) lists three working carrier frequencies for Morse code and data transmissions in the 
472-479 kHz band as being assignable to coast stations located in designated geographic areas.  Only one coast 
station is licensed to operate on each of these frequencies:  The New England Historical Radio Society, Inc. on 
carrier frequency 472 kHz using a necessary bandwidth of 160 hertz and 5 kW of output power at Stoneham, 
Massachusetts and Globe Wireless on both carrier frequency 476 kHz using a necessary bandwidth of 160 hertz and 
30 kW of output power at Palo Alto, California and on carrier frequency 478 kHz using a necessary bandwidth of 
160 hertz and 17.6 kW of output power at Pearl River, Louisiana.  See call signs WNE, KFS, and WNU.

167. Service Rules for the 135.7-137.8 kHz and 472-479 kHz bands.  We are proposing 
service rules for the amateur service in the 135.7-137.8 kHz and 472-479 kHz bands with the principal 
goal of enabling sharing of this spectrum among licensed amateur stations and unlicensed PLC systems.
367
  
As the demand for radio spectrum has continued to increase, we have sought to make more efficient use 
of spectrum by providing for sharing of frequency bands for multiple purposes.
368
  While we recognize 
the importance of PLC systems to the functioning of the electric power grid, we also believe that there are 
benefits to providing amateurs access to these bands, including providing amateurs with new 
opportunities for experimentation.  Moreover PLC systems and the expected amateur use of these bands 
have characteristics which make coexistence possible.  PLC systems are limited to use on transmissions 
lines and, consequently, are not present in most residential neighborhoods where amateur licensees live.  
The amateur service is expected to use the band mainly for experimental purposes and not for routine and 
widespread communications activities common in other bands.  These attributes give us confidence that, 
along with appropriate technical rules, amateur stations can harmoniously operate on the same frequency
bands as PLC systems.
168. The cornerstone of the technical rules we are proposing is physical separation between 
amateur stations and the transmission lines upon which PLC systems may be present.  We propose that 
amateur stations be permitted to operate in these bands when separated from transmission lines by a 
specified distance.  Such a separation, in conjunction with limits on the amateur stations’ transmitted 
EIRP and antenna heights, will enable PLC systems and amateur stations to coexist in these bands.
369
  In 
addition, we propose to limit amateur stations to operations at fixed locations only to ensure that this 
separation distance can be maintained reliably.
370
  We seek comment on this overall framework.
169. In order to develop the necessary and appropriate service rules to meet our goal of 
providing for the coexistence of amateur services and PLC systems in these bands, we seek detailed 
comment on the technical characteristics of both the PLC systems and the amateur stations.  This 
information will allow us to set an appropriate separation distance.  Although the Commission in the 
WRC-07 NPRM inquired into the technical rules and methods that would assure coexistence, commenters 
provided little in the way of concrete information.
371
  ARRL submitted a technical analysis based on an 
NTIA technical report supporting an assertion that PLC systems in the 135.7-137.8 KHz band will be 
sufficiently protected from amateur stations transmitting at an EIRP of 1 W with a separation distance of 
1 km from the transmission lines carrying the PLC signals.
372
  However, this NTIA technical report is 
from 1985 and therefore may not account for any subsequent developments.
170. To assist us in determining the optimal separation distance, we invite commenters to 
submit information on the technical characteristics of PLC systems that are currently being operated by 
utilities or likely to be deployed in the future.  How tolerant are these PLC systems of signals received 
from other stations transmitting in the same band?  What electric field strength at the location of a 
transmission line will cause a PLC system operating on that line to malfunction?  What types of 
                                                     
367
PLC systems operate under Part 15 of our rules and are not permitted to cause interference and must accept 
interference from licensed services.  47 C.F.R. §§ 15.5, 15.113 
368
See n.81, supra.
369
As we noted in the WRC-07 R&O, the existing record offers support to the imposition of power limits and other 
technical rules to assure compatibility with PLC systems.  See para. 23, supra.
370
As ARRL admits, it would be appropriate to place regulatory limits on amateur stations based on proximity to 
transmission lines carrying PLC signals and an amateur licensee has suggested limiting amateur operations to fixed 
locations. ARRL Comments at 17 (“Distance separation of less than one kilometer would therefore be an 
appropriate trigger for any regulatory limits other than EIRP.”); Davis Reply at 4.

malfunctions would the electric power grid experience from electrical interference?  How many PLC 
systems are currently operating in the 2200 and 630 Meter bands?  Can these existing PLC systems be 
modified and could new PLC systems be designed to operate in other portions of the 9-490 kHz band, 
thus avoiding co-channel operation with amateur services? At what power do these PLC systems operate 
and how long are the transmission lines over which they send signals?  At what voltage level do the 
transmission lines upon which these PLC systems are deployed operate and how does the PLC systems’ 
tolerance of other signals depend on the voltage level?  What electric field strengths are produced in the 
vicinity of transmission lines by the PLC signals traveling over the transmission lines?
171. We likewise invite information on the technical characteristics of amateur stations that 
are likely to be deployed or have operated under experimental licenses in these two bands.  What electric 
field strength generated by PLC systems operating on transmission lines would impede the operation of 
amateur stations?  A study conducted on a PLC system operating at 1 W at 152 kHz found that the PLC 
system generated an electric field strengths of 20 db?V/m at 1 km.
373
  Would a signal with this field 
strength interfere with the operation of amateur stations?  Given that high-voltage transmission lines 
generate a significant level of noise at this frequency range, how close to high-voltage transmission lines 
can amateur stations realistically operate?  In recent years amateur stations have operated in these bands 
under experimental licenses with most licenses permitting powers of between 1 to 20 watts ERP.
374
  How 
close did these amateur stations operate to transmission lines?  Did any of these amateur stations receive 
signals from PLC systems operating on transmission lines?  Do the experiences of amateur stations and 
utilities in other countries and along the United States border with Canada yield any useful 
information?
375
172. If we were to adopt our proposal to permit amateur operations only when separated by a 
specified distance from transmission lines, when a new transmission line is built close by an amateur 
station, the station either would have to relocate farther away from the transmission line or cease 
operating.  How should our rules address the potential for new transmission lines to be constructed closer 
than the specified distance to pre-existing amateur stations?  We do not want to inhibit the ability of either 
PLC systems or amateur services to grow and expand without imposing unnecessary burdens on either. Is 
it possible for utilities to refrain from geographically expanding their PLC operations within the relatively 
small portion of the 9-490 kHz band that we are making available for amateur operations, and is this 
something utilities would do on their own accord, given the Part 15 status of PLC systems?  Should our 
rules explicitly prohibit utilities from deploying new PLC systems in these bands?
173. We seek comment on how changes to the structure and design of the electric power 
system might affect our technical analysis.  For example, the modernization of the U.S. power system to 
provide a more efficient and stable transmission and distribution network, which has been referred to as 
the “smart grid,” requires wide-area monitoring of the electric grid, two-way communications, and 
enhanced control functions.
376
  These communication needs may be met by increased use of PLC 
systems.
377
  Are utilities likely to deploy more PLC systems in these bands in the future to meet the 
communication needs of the smart grid?  Are the characteristics of these PLC systems likely to differ 
from PLC systems that have been used by utilities in the past?  A recently adopted IEEE standard

(1901.2-2013) is designed for smart grid applications over distribution lines below 500 kHz.
378
  Because 
these systems operate over the distribution lines to residences and businesses rather than over 
transmission lines, they are considered carrier current systems rather than PLC systems under the 
Commission’s rules.  Unlike PLC systems, carrier current systems may operate on any power line and are 
not limited to the 9-490 kHz band.  However, carrier current systems are subject to limits on radiated 
power that do not apply to PLC systems.
379
  What is the likelihood that carrier current systems will be 
deployed over distribution lines and operate in the two frequency bands of concern in this proceeding?  
Will these systems be used for tasks critical to the functioning of the electric grid or will they used for 
non-critical purposes such as metering?  Are amateur stations operating in these bands likely to prevent 
these carrier current systems from operating or receive harmful interference from these systems? 
174. We also seek comment on the applicability of IEEE 1613-2009 – IEEE Standard 
Environmental and Testing Requirements for Communications Networking Devices Installed in Electric 
Power Substations (IEEE 1613-2009) to our analysis.
380
ARRL claims that PLC systems complying with 
IEEE-1613 “would virtually guarantee that there would be no interaction between [a]mateur stations and 
PLC systems,” and that compliance with the standard has been required by the Commission’s since 
2002.
381
  As background, the Commission’s rules require that PLC systems conform to engineering 
standards promulgated by the Commission and adhere to industry approved standards designed to 
enhance the use of PLC systems.
382
  Is compliance with this IEEE standard required by the Commission’s 
rules (i.e. is this an industry approved standard designed to enhance the use of PLC systems)?  Would 
compliance of PLC systems with this standard facilitate the sharing of these bands between amateur 
stations and PLC systems?  Are there PLC systems deployed that do not comply with this standard? 
Would compliance with this standard obviate the need for amateur stations to maintain a specific 
separation distance from transmission lines?
175. We recognize that the separation distance required for PLC systems and amateur stations 
to coexist will depend on the power at which the amateur stations are permitted to transmit. We propose 
that amateur stations in the 135.7-137.8 kHz band be limited to a maximum EIRP of 1 W, as is required 
by footnote RR 5.67A, and which we adopted in the WRC-07 R&O.  Is this EIRP limit appropriate for 
facilitating sharing between PLC systems and amateur stations?  For the 472-479 kHz band, we propose 
to adopt transmitted power limits consistent with RR 5.80A.  Amateur stations will be limited to an EIRP 
of 1 W in the portion of Alaska within 800 km of the Russian Federation and will be permitted to transmit 
at up to 5 W EIRP elsewhere.  Is this EIRP limit appropriate for PLC systems and amateur stations to 
share this band?  Should amateur stations be required to reduce their EIRP below 5 W when close to 
transmission lines and at what distances?  We seek comment on these proposals.
176. We also seek comment on the practical application of a separation distance requirement, 
and, specifically, what resources and information amateur radio operators will need to comply with our 
rules.  Amateur licensees will have to determine the location of transmission lines in their vicinity to 
determine if they are permitted to operate stations using these frequency bands.  The amateur licensees 
will need to differentiate transmission lines from the electric distribution lines that connect distribution 
substations to customer or house wiring.  High voltage transmission lines are typically attached to large 
steel towers that are easy to identity.  However, lower voltage transmission lines are typically attached to 
wooden poles.  Although the wooden poles used for transmission lines are usually taller than the wooden

poles used for distribution lines,
383
we recognize that distinguishing the two types may not always be 
straightforward.  We seek comment on whether amateur licensees will be able to identify the transmission 
lines in their locality.  If amateur licensees are not able to reliably identify transmission lines, should we 
require amateurs or ARRL to affirmatively verify the locations of transmission lines with utilities or UTC 
before an amateur station begins transmitting?
384
177. There are several different ways that we could specify the separation distance between 
the amateur stations and the transmission lines.  We could specify the slant-range distance as is defined in 
our Part 15 rules.
385
  The slant range distance is the diagonal distance measured from the center of the 
measurement antenna to the nearest point of the overhead power line.  However, calculation of the slant 
range distance is complicated by the need to know the height of the transmission line at the point closest 
to the measurement antenna as well as the height of the center of the measurement antenna.  For 
simplicity we propose instead to specify the separation distance in terms of the horizontal distance 
between the transmission line and the amateur station antenna.  This is the horizontal (lateral) distance 
between the center of the amateur station antenna and a vertical projection of the overhead transmission 
line down to the height of the center of the amateur station antenna.  This distance could be calculated 
from the coordinates (i.e. latitude and longitude) of the amateur station antenna and the coordinates of the 
nearest point on the transmission line without having to know the heights of the antenna or the 
transmission line.  We seek comment on this proposal.
178. Lastly, we seek comment on additional service and operational rules that would be 
appropriate for amateur operations in these bands.  According to ARRL, the tallest antenna that should 
reasonably be considered for an amateur station is 200 feet, because antennas with greater heights would 
be required to obtain prior FAA approval and have to comply with FAA painting and lighting 
requirements.
386
  We note that adopting a maximum antenna height for amateur stations in these bands 
will aid in sharing of the spectrum with PLC systems by limiting the number of transmission lines that 
would potentially be in direct line-of-sight of amateur station antennas.  We seek comment on what 
maximum antenna height, if any, we should adopt for amateur stations in these bands.
179. We also invite comment on whether to adopt transmitter power limits for amateur 
stations, in addition to the EIRP limits we are proposing.  If so, we seek comment on what the power 
limits should be. We observe that, in the 2002 Amateur Radio NPRM, the Commission proposed to limit 
the maximum transmitter power in the 135.7-137.8 kHz band to 100 W PEP because of the possible 
difficulty of measuring the EIRP of an amateur station in this frequency range.
387
  Also, in 1998, ARRL 
submitted data for the 135.7-137.8 kHz band showing that relatively short antennas can only produce 
ranges of EIRP that are well below the ITU’s 1 W EIRP limit (i.e., 10-40 mW for a 100 foot antenna and 
1-4 mW for a 50 foot antenna) with a transmitter power output of 200 W PEP.
388
  The Commission did 
                                                     
383
Because low-voltage transmission lines operate at higher voltages than distribution lines, the wooden poles they 
are attached to are usually taller to prevent arching of the electric current to nearby trees, structures, and people.

See ARRL LF Erratum at 13.  We note that a recent ITU-R recommendation states that a representative system 
for the 2200 meter band would have a transmitter output power of 23 dBW (200 W), a transmitter (transmission) 
line loss of 0 dB, and a (transmitting) antenna gain of -22 dBi.  This would result in an EIRP of 1 dBW [i.e., 
23 dBW + 0 dB + (-22 dBi) = 1 dBW = 1.259 W], which exceeds the WRC-07 EIRP limit of 0 dBW (1 W).  See 
Recommendation ITU-R M.1732-1 (03/2012), p. 3, Table 1.

not consider either power limit at that time, because, as noted above, it decided not to adopt an allocation 
for amateur operations in this band.
389
  Given that we have adopted such an allocation in the WRC-07 
R&O above,
390
do either the 2002 Amateur Radio NPRM or ARRL’s 1998 study provide a basis for 
determining transmitter power limits now?  Should these transmitter power limits vary depending on 
antenna height – e.g. we could allow a 200 W PEP limit for antenna heights not exceeding 30.5 meters 
while permitting only 100 W PEP for taller antennas.  Should the transmitter power limits differ between 
the 135.7-137.8 kHz band and the 472-479 kHz bands?
180. In response to the WRC-07 NPRM, commenters addressed a number of steps that could 
facilitate amateur use of the 135.7-137.8 kHz band.  Amateur operator John H. Davis (Davis) proposed 
that no amateur station should be automatically controlled to ensure that the amateur operator is able to 
quickly terminate transmissions if necessary.
391
  Davis also suggested that it may be appropriate to also 
prohibit software-driven modes that determine their own operating frequency without human intervention.  
Should we adopt Davis’s suggestions?  ARRL’s states that there is no rationale for limiting the occupied 
bandwidth in the 135.7-137.8 kHz band to less than the full 2.1 kilohertz, and that a stricter limit would 
not be conducive to experimentation with narrowband data emission modes in the future.
392
  Should we 
adopt any bandwidth limitation for either of the frequency bands? In the WRC-07 NPRM, the 
Commission requested comment on whether it should limit operating privileges in the 135.7-137.8 kHz 
band, e.g., to Amateur Extra Class licensees.
393
  None of the commenters believe that such a restriction 
would better facilitate Amateur/PLC sharing of the band.
394
  In particular, we note that ARRL states that it 
would be consistent with Commission policy to make this frequency band available to Amateur Extra, 
Advanced, and General Class licensees.
395
  Should we limit operating privileges for these bands in 
accordance with ARRL’s statement?  Should we propose to authorize CW (international Morse code 
telegraphy), RTTY (narrow-band direct-printing telegraphy), and data emissions throughout the 630 and 
2200 meter bands as we did for our 2200 meter band proposal in 2002?
396
  We also seek comment on 
amending Section 97.3 by adding definitions for the terms effective radiated power, isotropically radiated 
power, and LF.
397
181. Other Allocated Uses.  Other radio services use the 135.7-137.8 kHz band.  In the 
U.S. Table, the 130-160 kHz band is allocated to the fixed service (FS) and maritime mobile service

Amateur stations would be permitted to utilize CW (continuous wave) emissions in the band per existing 
Section 97.305(a), and thus, our proposed rules list only RTTY (radio teletype) and data in Section 97.305(c).  For 
the definitions of CW, data, and RTTY, see Section 97.3 at paragraphs (c)(1), (c)(2), and (c)(7), respectively. This 
proposal is consistent with the Whedbee LF Petition.  See n.43, supra, p. 4.

The proposal to add the definition of the term “LF” to Section 97.3 is consistent with the Whedbee LF Petition.

(MMS) on a primary basis for Federal and non-Federal use.
398
While there are no non-Federal stations in 
the FS and MMS that are licensed to operate in the 135.7-137.8 kHz band, there is limited Federal use of 
this band.
399
Specifically, a Federal coast station located in Dixon, California transmits to ships in the 
Pacific Ocean on two frequencies that overlap portions of this band.  Given that this coast station also 
transmits on 19 other LF frequencies, we have requested that NTIA consider whether Federal 
requirements can be met without operating in this narrow (2.1 kilohertz) band.  The 126.7-141.7 kHz 
band is also used to track tagged salmon in the Pacific watershed.  We seek comment on whether we need 
to adopt exclusion zones or use other methods to protect these Federal uses of the band.
400
  Should we 
delete the unused non-Federal allocations from this band?  To be consistent with the International Table, 
we also propose to require that amateur fixed stations operating in the 2200 meter band not cause harmful 
interference to stations in the FS and MMS that are authorized by other nations and require that these 
amateur stations take any and all corrective action, if harmful interference is reported to us.
401
  We seek 
comment on these proposals.
182. Finally, we note that the 472-479 kHz band has unused Federal MMS and ARNS 
allocations.  Should we remove these allocations from the Federal Table?  To be consistent with the 
International Table, we propose that amateur stations transmitting in the 630 meter band not cause 
harmful interference to, and must accept interference from, stations authorized by other nations in the 
ARNS and MMS and that the amateur stations must cause no harmful interference to 490 kHz.
402
  Should 
we take any action with regard to the non-Federal MMS allocation in the band?  We seek comment on 
these proposals.
B. Maritime Issues and Oceanographic Radars
1. Maritime Mobile Service Use of the Frequency 500 kHz
183. Background.  Prior to WRC-12, the 495-505 kHz band was allocated to the mobile 
service on a primary basis in all ITU Regions, and two international footnotes (RR 5.82A, RR 5.82B) 
applied to this band.  RR 5.82A stated that the use of this band was limited to radiotelegraphy.  RR 5.82B
required that the use of the 495-505 kHz band by services other than the maritime mobile service (MMS) 
not cause harmful interference to the MMS.  In the United States, the 495-505 kHz band is allocated to 
the mobile service on a primary basis for Federal and non-Federal use, restricted to distress and calling 
operations.
403
                                                     
398
The FS is a radiocommunication service between specified fixed points, and the MMS is a mobile service 
between coast stations and ship stations, or between ship stations, or between associated on-board communication 
stations; survival craft stations and emergency position-indicating radiobeacon stations may also participate in this 
service.  47 C.F.R. § 2.1(c).
399
On March 31, 2015, the staff conducted a study of the 135.7-137.8 kHz band using the Commission’s Universal 
Licensing System (ULS) and found no active call signs.
400
If we adopt exclusion zones, ARRL could prevent amateur licensees from registering amateur fixed stations in 
the exclusion zones when amateur licensees register with ARRL.
401
The 135.7-137.8 kHz band is allocated on a primary basis to these services in all Regions in the International 
Table.  47 C.F.R. § 2.106.
402
The 472-479 kHz band is allocated on a primary basis to the MMS in all Regions in the International Table. 
47 C.F.R. § 2.106.  RR 5.80A provides that amateur stations shall not cause harmful interference to nor claim 
protection from stations in the ARNS.  RR 5.82 provides that amateur stations in the band cause no interference to 
490 kHz.  See revised text of RR 5.80A and RR 5.82 in Appendix D. 
403
WRC-12 also adopted a related U.S. proposal to restrict the primary mobile service allocation in the 510-525 kHz 
band to the MMS in ITU Region 2.  This allocation has already been implemented in the U.S. Table.
Federal Communications Commission FCC 15-50
67
184. The United States proposed that WRC-12 restrict the use of the mobile service allocation 
in the 495-505 kHz band to the MMS.
404
  In support of this proposal, the United States stated that the 
broadcast of safety and security information to and from ships is vital for maritime safety.  Due to further 
requirements for spectrum to accommodate existing and new maritime systems, the United States stated 
that an exclusive primary MMS allocation in the 495-505 kHz band is vital for the maritime community 
to have a globally harmonized primary MMS allocation for maritime safety information (MSI), 
security-related broadcasts, and data communication systems.
405
  The United States also proposed that 
WRC-12 delete RR 5.82A and RR 5.82B, which would become unnecessary as a consequence of this 
proposal.
185. Proposal.  WRC-12 adopted the U.S. proposal
406
and NTIA recommends that we 
implement these WRC-12 allocation changes in the U.S. Table.
407
  Accordingly, we propose to reallocate 
the 495-505 kHz band to the MMS on a primary basis for Federal and non-Federal use.  This action is 
expected to provide spectrum for digital broadcasting of maritime safety and security related information 
via automated broadcasts in a manner that can coexist with existing services.
408
  We request comment on 
this proposal.
2. Oceanographic Radar Applications in the 4-44 MHz Range
186. Background.  Oceanographic radar systems measure the speed and direction of ocean 
surface currents in near-real time.  The ability to collect this data supports pollutant tracking, search and 
rescue, harmful algal bloom monitoring, navigation, and ecosystem assessment.  The U.S. currently 
operates 143 oceanographic radars and plans to install 208 additional such radars.
409
187. In preparation for WRC-12, the United States observed that these oceanographic radars 
have been operating for more than 30 years on an experimental, non-interference basis, and that 
uncoordinated global frequency use has resulted in band congestion.
410
  At the same time, parties are 
increasing their reliance on the data from these systems for maritime safety, oceanographic, 
climatological, meteorological, and disaster response purposes.
411
  Use of frequencies higher than 50 MHz

See U.S. Proposals for WRC-12, First Tranche, Agenda Item 1.10.  See also CPM Report to WRC-12, Chapter 1, 
Agenda Item 1.10, 1/1.10/3.3 (Broadcasts of safety and security information for ships and ports), pp. 83; Report 
ITU-R M.2201 (Utilization of the 495-505 kHz band by the maritime mobile service for the digital broadcasting of 
safety and security related information from shore-to-ships), 11/2010.
405
When considered along with the change noted in n.403, supra, the addition of the MMS allocation in the 
495-505 kHz band would result in a continuous MMS allocation from 415 kHz to 525 kHz in Region 2 (extending 
to 526.5 kHz in Regions 1 and 3).
406
Specifically, WRC-12 allocated the 495-505 kHz band to the MMS on a primary basis in all ITU Regions and 
deleted RR 5.82A and RR 5.82B.  See WRC-12 Final Acts, p. 9.
407
See NTIA WRC-12 Implementation Recommendations, p. 3.
408
The U.S. proposal also noted that maritime communication systems in the 415-526.5 kHz band include 
transmissions in accordance with Recommendations ITU-R M.540 (Operational and technical characteristics for an 
automated direct-printing telegraph system for promulgation of navigational and meteorological warnings and 
urgent information to ships), ITU-R M.1677 (International Morse code), and ITU-R M.1798 (Characteristics of HF 
radio equipment for the exchange of digital data and electronic mail in the maritime mobile service); that these 
systems currently operate in support of maritime applications other than those used for radiotelegraphy; and that 
based on current worldwide operational experience, other maritime applications are compatible with 
radiotelegraphy.  See also Report ITU-R M.2201, n.404, supra, p. 2.

limits the ability of oceanographic radar systems to provide useful data.  Furthermore, oceanographic 
radars have a relatively large operational range (on the order of 200 km).
188. The U.S. proposed that WRC-12 provide spectrum for the operation of oceanographic 
radars in the 3-44 MHz range while minimizing the impact on incumbent fixed and mobile service 
users.
412
  Specifically, the U.S. proposed that WRC-12 allocate seven HF bands and two VHF bands to the 
radiolocation service (RLS) on a primary basis in all Regions, with the following international footnote 
limitation:  “Stations in the radiolocation service shall not cause harmful interference to, nor claim 
protection from, stations operating in the fixed and mobile services.  Resolution 612 (Rev.WRC-12) shall 
apply.”  Additionally, the U.S. proposed that WRC-12 revise Resolution 612, which specifies the 
operating parameters for oceanographic radars. Given the increased use of oceanographic radars and their 
unique technical requirements, the U.S. suggested that the proposal would improve the regulatory status 
of oceanographic radars without sacrificing the protection of existing allocated services.
413
189. WRC-12 allocated six HF bands and two VHF bands to the RLS for use by 
oceanographic radars in Region 2.  Specifically, WRC-12 allocated a total of 695 kilohertz of HF 
spectrum as follows:  five of these bands (4.438-4.488 MHz, 5.25-5.275 MHz, 16.1-16.2 MHz, 
24.45-24.65 MHz, and 26.2-26.42 MHz) are allocated on a primary basis in Region 2 (and on a secondary 
basis in Regions 1 and 3),
414
and one band (13.45-13.55 MHz) is allocated on a secondary basis in all 
Regions.  WRC-12 allocated the 1.3 megahertz of VHF spectrum (41.015-41.665 MHz and 
43.35-44 MHz) proposed by the U.S. on a primary basis, but limited the use of these allocations to the 
United States and South Korea.
415
190. In the International Table, all of the bands that WRC-12 allocated to the RLS are also 
allocated to the fixed service on a primary basis and seven of these bands are also allocated to the mobile 
service or to a subset of the mobile service.
416
  In order to protect these incumbent services, WRC-12 
adopted three international footnotes (RR 5.132A, RR 5.145A, and RR 5.161A), which limit the use of 
these RLS allocations to oceanographic radars operating in accordance with Resolution 612 
(Rev.WRC-12) and require that these oceanographic radars not cause harmful interference to, or claim 
protection from, stations operating in the fixed or mobile services.  We also note that WRC-12 updated 
Resolution 612.

through the collection of sea state and dominant ocean wave data.  In addition, HF surface wave radar technology 
has applications in global maritime domain awareness by allowing the long-range sensing of surface vessels.
412
See U.S. Proposals for WRC-12, Second Tranche, Agenda Item 1.15.

Id.
414
In Regions 1 and 3, WRC-12 allocated only the narrower 24.45-24.60 MHz band, i.e., the 24.60-24.65 MHz 
sub-band is not allocated for oceanographic radar use in Regions 1 and 3.
415
See RR 5.161A.
416
In Region 2, the 4.438-4.488 MHz band is allocated to the mobile except aeronautical mobile (R) service (MS 
except AM(R)S) on a primary basis, the 5.25-5.275 MHz and 26.2-26.42 MHz bands are allocated to the mobile 
except aeronautical mobile service (i.e., the land mobile service (LMS) and the maritime mobile service (MMS)) on 
a primary basis, the 13.45-13.55 MHz band is allocated to the MS except AM(R)S on a secondary basis, the 
24.45-24.65 MHz band is allocated to the LMS on a primary basis, and the 41.015-41.665 MHz and 43.35-44 MHz 
bands are allocated to the MS on a primary basis.  (The 16.1-16.2 MHz band is allocated only to the FS.)
417
In its revision of Resolution 612, WRC-12 resolved that: 1) when oceanographic radars are brought into use after 
February 17, 2012, and notified to the ITU’s Radiocommunication Bureau, the notification must be in accordance 
with Radio Regulation No. 11.2 and must contain the station identification (call sign); 2) the peak EIRP of an 
oceanographic radar must not exceed 25 dBW (316 W); 3) each oceanographic radar station must transmit a station 
identification (call sign) on the assigned frequency, in international Morse code at manual speed, at the end of each 
data acquisition cycle, but at an interval of no more than 20 minutes; 4) oceanographic radars should, where 
applicable, use techniques that allow multiples of such radars to operate on the same frequency, reducing to a

191. NTIA recommends that we implement in the U.S. Table all the RLS allocations WRC-12 
adopted for oceanographic radar applications in ITU Region 2.
418
  NTIA also recommends that we add 
references to the appropriate international footnote in the bands allocated for Federal/non-Federal shared 
use (i.e., RR 5.132A in the 4.438-4.488 MHz, 5.25-5.275 MHz, 13.45-13.55 MHz, and 24.45-24.65 MHz
bands, and RR 5.145A in the 16.1-16.2 MHz band), and that we adopt four U.S. footnotes that would 
apply to the bands allocated exclusively for Federal use (41.015-41.665 MHz) or for non-Federal use 
(26.2-26.42 MHz, 43.35-43.69 MHz, and 43.69-44 MHz).
419
  Additionally, NTIA recommends that we 
raise the secondary mobile except aeronautical mobile service allocation in the 5.25-5.275 MHz band to 
primary status.
192. Proposal.  We support the U.S. objective to provide allocated spectrum for the operation 
of oceanographic radars, while minimizing their impact on incumbent fixed and mobile service users.  We 
also agree that allocating the WRC-12 oceanographic radar bands would better organize and reduce
spectrum requirements for these operations.  We therefore propose to allocate the eight WRC-12 
frequency bands in the 4-44 MHz range to the RLS for Federal and non-Federal use, limited to 
oceanographic radar applications.
193. Specifically, we propose to allocate seven frequency bands (4.438-4.488 MHz, 
5.25-5.275 MHz, 16.1-16.2 MHz, 24.45-24.65 MHz, 26.2-26.42 MHz, 41.015-41.665 MHz, and 
43.35-44 MHz) to the RLS on a primary basis for Federal and non-Federal use and to allocate the 
13.45-13.55 MHz band to the RLS on a secondary basis for Federal and non-Federal use.
194. To minimize the impact on the incumbent fixed and mobile services, we propose that 
oceanographic radars may not cause harmful interference to, or claim protection from, existing and future 
stations in the incumbent fixed and mobile services.  As requested by NTIA, we seek to implement this 
proposal in the U.S. Table by adding RR 5.132A to four HF bands (4.438-4.488 MHz, 5.25-5.275 MHz, 
13.45-13.55 MHz, and 24.45-24.65 MHz), RR 5.145A to the 16.1-16.2 MHz band, and a U.S. footnote 
(tentatively numbered as US132A) to the 26.2-26.42 MHz, 41.015-41.665 MHz, and 43.35-44 MHz
bands.
420
  Further, we propose to raise the secondary mobile except aeronautical mobile service allocation 
(Continued from previous page)                                                           
minimum the spectral occupancy of a Regional or global deployment of radars; 5) oceanographic radars should use 
directional antennas, where applicable and as required, to facilitate sharing, thereby reducing the EIRP in the 
direction of the transmit antenna backlobe; and 6) the separation distances between an oceanographic radar and the 
border of other countries must be greater than the distances specified in the following table, unless prior explicit 
agreements from affected administrations are obtained:
Frequency (MHz)
Land path (km) Sea or mixed path (km)
Rural Quiet rural Rural Quiet rural
5 (± 1 MHz) 120 170 790 920

420
In order to simplify the codification of oceanographic radar use in the U.S. Table, we have combined NTIA’s 
recommended footnotes (US[26.2MHz], US[41.015MHz], US[43.35MHz], and US[43.69MHz]) into a single new 
U.S. footnote.  See Appendix F for the text of proposed footnote US132A.

in the 5.25-5.275 MHz band to primary status, so that existing and future stations in this service can also 
be protected from interference from oceanographic radars.
195. We are most concerned about the potential for interference from oceanographic radars in 
the 4.438-4.488 MHz and 26.2-26.42 MHz bands.  Several university-operated stations authorized on 
frequencies in the 4-44 MHz range under experimental licenses were required to adjust their operations 
because of interference caused to incumbent stations authorized in the fixed and mobile services.
421
  
Given these incidents, we note that operators of oceanographic radars would be required to cease 
operations if notified that they are causing harmful interference, and operations will not resume until the 
cause of the harmful interference is corrected.
196. Our proposed rules are based on the conditions specified in Resolution 612 (Rev.WRC-
12).  We propose to amend Part 90 of the Commission’s rules to bring the oceanographic radar allocations 
into immediate effect.  Specifically, we propose to amend Section 90.103 by listing the eight
oceanographic radar bands in the table within paragraph (b), to limit station class of these radars to 
radiolocation land stations, and to restrict the use of these bands by adding new Limitation 3, which 
would be codified in new paragraph (c)(3).  Specifically, we propose that new paragraph (c)(3) read as 
follows:
Operations in this band are limited to oceanographic radars using transmitters with a peak 
equivalent isotropically radiated power (EIRP) not to exceed 25 dBW.  Oceanographic radars 
must not cause harmful interference to, nor claim protection from interference caused by, stations 
in the fixed or mobile services as specified in § 2.106, footnotes 5.132A, 5.145A, and US132A.  
See Resolution 612 of the ITU Radio Regulations for international coordination requirements.  
Operators of oceanographic radars are urged to use directional antennas and techniques that allow 
multiples of such radars to operate on the same frequency.
Because the power limitation in Resolution 612 is specified in peak EIRP, we also propose to reflect the 
Part 2 definition of this term in Section 90.7 of the Commission’s rules.
422
197. Finally, we propose to require that licensees of oceanographic radars that currently 
operate under Part 5 of the rules transition their operations to frequencies within an allocated band within 
five years of the adoption of final rules in this proceeding.  We request comment on all of our proposals.
3. Improved Satellite-AIS Capability
198. Background.  In the WRC-07 R&O, we implemented several WRC-12 allocation actions 
that were taken to support maritime safety requirements in the two existing bands (AIS 1 and AIS 2) used 
by maritime Automatic Identification Systems.
423
  In this section, we address the new mobile-satellite 
service (MSS) allocations that WRC-12 adopted for the purpose of improving satellite detection of AIS 
messages.
199. In the U.S. Table, the 156.7625-156.8375 MHz band (75 kilohertz) is currently allocated 
on a primary basis to the maritime mobile service (MMS) (distress, urgency, safety, and calling) for 
Federal and non-Federal use.  Prior to WRC-12, this band was allocated in the International Table to the 
MMS (distress and calling) on a primary basis in all Regions.

Our Enforcement Bureau has investigated numerous interference complaints related to the operation of 
experimental coastal radars dating back to at least the year 2000.

For consistency within Part 90 of the rules, we use the abbreviation “EIRP” (instead of “e.i.r.p.,” which is the 
abbreviation used in the ITU Radio Regulations and in Part 2 of the rules).

In the case where there is a parenthetical addition to an allocation in the International Table, that service 
allocation is restricted to the type of operation so indicated.  47 C.F.R. § 2.104(h)(4).  RR 5.226 states, inter alia, 
that the frequency 156.8 MHz is the international distress, safety and calling frequency for the maritime mobile VHF 
(continued….)

WRC-12 adopt a new international footnote, which would state that the frequencies 156.775 MHz 
(channel 75) and 156.825 MHz (channel 76) are also allocated to the MSS (Earth-to-space) for the 
reception of AIS emissions from stations operating in the MMS, solely using message 27 as specified in 
Recommendation ITU-R M.1371.
425
  In its support for the new allocations, the U.S. stated that satellite 
monitoring of AIS equipped vessels is critical to search and rescue, safety of navigation, and the safe 
movement and tracking of vessels.
426
  Further, the U.S. cited recent ITU-R studies which indicate that the 
recommended allocations are well-suited to allow for the use of satellite-AIS messages in a manner 
compatible with the existing allocations.
427
200. WRC-12 divided the 156.7625-156.8375 MHz band into three 25 kilohertz-wide bands: 
156.7625-156.7875 MHz (AIS 3 with a center frequency of 156.775 MHz), 156.7875-156.8125 MHz 
(channel 16 with a center frequency of 156.800 MHz), and 156.8125-156.8375 MHz (AIS 4 with a center 
frequency of 156.825 MHz), so that the bands on either side of channel 16 (i.e., AIS 3 and AIS 4) could 
also be allocated to the MSS (Earth-to-space) on primary basis in Region 2 and on a secondary basis in
Regions 1 and 3.
428
  WRC-12 also adopted RR 5.228, which limits MSS (Earth-to-space) use of the AIS 3 
and AIS 4 bands “to the reception” of emissions of long-range AIS broadcast messages (Message 27), and 
– with the exception of AIS emissions – requires that the emissions in these bands by MMS systems
“shall not exceed 1 W.”
201. NTIA recommends that we implement the WRC-12 decision by reallocating the AIS 3
and AIS 4 bands to the MSS (Earth-to-space) on a primary basis for Federal and non-Federal use, limited 
to AIS operations only.
429
  Further, NTIA recommends that we limit the use of these MSS allocations by 
adding the following use limitation to footnote US52:  “The frequencies 156.775 MHz (A1S 3) and 
156.825 MHz (AIS 4) are allocated exclusively to the MSS (Earth-to-space) for the reception of long-
range broadcast messages from ships (Message 27; see most recent version of ITU-R M.1371).”  In 
(Continued from previous page)                                                           
radiotelephone service and that the conditions for the use of this frequency and the 156.7625-156.8375 MHz band 
are contained in Article 31 and Appendix 18.
425
The United States also proposed that a similar note be added to Appendix 18 (channels 75 and 76 are allocated to 
the MSS (Earth-to-space) “for the transmission of AIS message 27 from ships”).  See U.S. Proposals to WRC-12, 
First Tranche, Agenda Item 1.10, pp. 2 and 4.
426
See, e.g., IMO Resolution MSC 74(69) (requiring that AIS improve the safety of navigation by assisting in the 
efficient navigation of ships, protection of the environment, and operation of Vessel Traffic Services (VTS)).
427
“The ITU-R completed studies to identify VHF channels in Appendix 18 for improved AIS satellite detection and 
recently updated Recommendation ITU-R M.1371-3, “Technical characteristics for an automatic identification 
system using time division multiple access in the VHF maritime mobile band,” to reflect specialized message 27 for 
long-range AIS broadcast messages of AIS Class A equipped vessels.  This proposed MSS (Earth-to-space) 
allocation for satellite AIS is compatible with the existing navigation-related communications of the frequencies as 
designated in Appendix 18, note n).  ITU-R Report M.2169, “Improved satellite detection of AIS,” and the recently 
updated ITU-R Recommendation M.1371-3 confirm the compatibility and show that the transmission of new AIS 
message 27 contains navigational information including position, speed over ground, course over ground, and 
navigational status.  The proposed MSS (Earth-to-space) frequencies (channels 75 and 76) are for navigation and 
serve as guard-bands for channel 16 – the safety and distress frequency.”  See U.S. Proposals to WRC-12, First 
Tranche, Agenda Item 1.10.  See also ITU-R Report M.2169 and Recommendation ITU-R M.1371-3.  We note, in 
particular, that:  “Transmission of Message 27 at 12.5 W only once every 3 min for 17 ms, alternating between 
channels 75 and 76 together with the restriction to not transmit when the ship is within range of an AIS base station, 
would not interfere with voice communications on any of these channels 16, 75 and 76...”  See ITU-R Report 
M.2169, Section 4 (Operating frequencies for satellite detection of AIS), p. 6.

addition, NTIA’s WRC-12 Implementation Recommendations included deleting the MMS allocations
from the AIS 3 and AIS 4 bands.
430
202. Proposal.  We propose to implement NTIA’s recommendations regarding satellite 
monitoring of AIS equipped ships as follows.  First, we propose to allocate the 156.7625-156.7875 MHz
(AIS 3) and 156.8125-156.8375 MHz (AIS 4) bands to the MSS (Earth-to-space) on a primary basis for 
Federal and non-Federal use.  The table entries for the MSS allocations would include the parenthetical 
additions “(Earth-to-space) (AIS 3)” and “(Earth-to-space) (AIS 4),” which would restrict the use of these 
MSS allocations to AIS emissions and operations in the Earth-to-space direction.  This action would 
make 50 kilohertz of spectrum available for ship earth stations to transmit maritime AIS messages to 
space stations in the MSS (Earth-to-space).  Designating these additional channels for satellite detection
of AIS messages from ship earth stations would improve vessel tracking and thereby enhance maritime 
safety and security.
203. Second, as requested by NTIA, we propose to remove the primary maritime mobile 
service allocation from the AIS 3 and AIS 4 bands.  Consequently, we propose to remove all references to 
the frequencies 156.775 MHz and 156.825 MHz from Part 80 of our rules.
431
  We note that there is a 
single licensee, BKEP Materials, LLC, authorized to operate private coast stations at three locations using 
these frequencies with an output power of 10 watts.
432
During our normal coordination process, the U.S. 
Coast Guard noted that ITU studies show that even a 1 watt station could cause interference to satellite 
reception in these bands. We propose to grandfather this existing MMS use in proposed footnote US52 
until the expiration date of these authorizations, set for August 26, 2019.  Therefore, we propose to 
require that operations on the frequencies 156.775 MHz and 156.825 MHz be terminated upon the 
expiration of the licenses, and to prohibit the license renewal of operations on these frequencies.  We note 
that there are an unknown number of ship stations that also operate on these frequencies.  We request 
comment on ship station usage, and on whether we should alternatively permit this limited MMS use to 
continue for a longer phase-out period.  If so, we alternatively propose to limit ship and coast stations 
operating on these channels to a transmitter output power of 1 W.  We request comment on these
proposals.  In particular, we request comment on whether these private coast station operations should be 
relocated to other maritime mobile frequencies no later than August 26, 2019.  If such relocation is not 
attainable by August 26, 2019, what would be the appropriate transition period?
204. Third, we propose to revise footnote US52 by adding new paragraph (b) to restrict the use 
of the proposed MSS uplink allocations to long-range AIS broadcast messages from ship earth stations 
and to codify in the U.S. Table the grandfathering provisions discussed above.
433
  Specifically, we 
propose that new paragraph (b) read as follows:
Except as provided for below, the use of the bands 156.7625-156.7875 MHz (AIS 3 with center 
frequency 156.775 MHz) and 156.8125-156.8375 MHz (AIS 4 with center frequency 156.825 
MHz) by the mobile-satellite service (Earth-to-space) is restricted to the reception of long-range 
AIS broadcast messages from ships (Message 27; see most recent version of Recommendation
ITU-R M.1371).  The frequencies 156.775 MHz and 156.825 MHz may continue to be used by 
                                                     
430
Id.
431
Specifically, we propose to amend: 1) Section 80.215 by removing note 13 from para. (c)(1) and by removing 
paragraph (g)(3); 2) Section 80.373 by removing these frequencies from the table in para. (f) and by removing note 
18; and 3) Section 80.871 by removing these frequencies from the table in para. (d).
432
Specifically, the Commission has issued five licenses that authorize private coast stations to transmit on the 
frequencies 156.775 MHz and 156.825 MHz using a bandwidth of 16 kilohertz and 10 watts of output power at three 
locations:  Catoosa, Oklahoma (WQKR767, WQKR768); Newport News, Virginia (WQKR769); and Saint Louis, 
Missouri (WQKR770, WQKR771).  The expiration date for all of these licenses is August 26, 2019.

Existing paragraphs (b) and (c) would be renumbered as (c) and (d), respectively.

non-Federal ship and coast stations for navigation-related port operations or ship movement until 
August 26, 2019.
205. We also note that satellite reception in the AIS 1 and AIS 2 bands is not protected from 
adjacent-band terrestrial stations operating in accordance with the terms of their licenses.  We seek 
comment on whether we should add such a requirement to the AIS 3 and AIS 4 bands.

C. Sharing Between AMT and Incumbent Services in the 4400-4940 MHz and 
5925-6700 MHz Bands
206. In this section, we examine an allocation issue that was not resolved through the WRC-07 
rulemaking process.  Aeronautical mobile telemetry for flight testing of aircraft (hereinafter, AMT) is an 
aeronautical mobile service (AMS) that transmits from an aircraft station to a receiving station the results 
of measurements made onboard an aircraft, including those related to the functioning of the aircraft.
435
  
Examples of AMT data include engine temperature, fluid pressure, and readings from control surface 
strain gauges.  In the United States, AMT operations are most often authorized in the 1435-1525 MHz, 
2200-2290 MHz, and 2360-2395 MHz bands.
436
207. At WRC-07, the United States was a leading proponent of global or Regional AMT 
allocations.  In its WRC-07 proposals, the United States stated that with the increasing complexity of 
aircraft design, pressure to shorten timescales for the development of new aircraft, and telemetry spectrum 
being diverted to other uses, there was a large and growing shortfall in the spectrum available for AMT 
                                                     
434
See Appendix F for the proposed revised text of footnote US52.
435
The AMS is a radiocommunication service between aeronautical (ground) stations and aircraft stations, or 
between aircraft stations.  47 C.F.R. § 2.1(c).  Major AMT test ranges are capable of supporting at least 2-6 
simultaneous tests.  A major test flight can involve as many as ten separate aircraft generating telemetry on many 
data and video channels that require nearly the entire available spectrum (i.e., 125 megahertz of primary MS 
spectrum), using current technologies.  The majority of AMT ground station antennas range in size from 2.4 to 5 
meters for operating distances less than 350 km.  Larger antennas are used only on ranges requiring extreme 
operating distances (350 km or more).  AMT relay platforms, such as a second aircraft, are often used to extend 
coverage over water and when over land, to other ranges.  It is not unusual for manned aircraft to traverse thousands 
of kilometers in test flights lasting 10-12 hours.  AMT relay stations can also be shipborne when long-range tests are 
conducted over water.  See United States of America, Draft New Report ITU-R M.[AMT], “Operational Description 
of Aeronautical Mobile Telemetry (AMT),” Document 8B/58-E, Aug. 19, 2004, at 2-4, 11.
436
The 2200-2290 MHz band is not available for non-Federal AMT use.  
Federal Communications Commission FCC 15-50

use.
437
  Further, due to rapidly increasing data rates associated with the testing of new and emerging 
technologies, “as much as an additional 650 megahertz may be required for aeronautical flight test 
telemetry.”
438
208. In the companion WRC-07 R&O we are allocating 59 megahertz for AMT use, with the 
adoption of the allocation for the 5091-5150 MHz band.  In this section, we are addressing two additional 
frequency bands that WRC-07 identified for AMT use.  Specifically, WRC-07 decided that the mobile 
service (MS) allocation in the 4400-4940 MHz and 5925-6700 MHz bands may be used for AMT flight 
test transmissions from aircraft stations in much of ITU Region 2 by adopting RR 5.440A and 
RR 5.457C.
439
  In addition, these international footnotes state that AMT use shall be in accordance with 
Resolution 416 (WRC-07)
440
and shall not cause harmful interference to, nor claim protection from, the 
fixed-satellite and fixed services.
441
  Resolution 416 places the following operational restrictions on AMT 
use of the 4400-4940 MHz and 5925-6700 MHz bands: 1) emissions are limited to transmissions from 
aircraft stations only; 2) AMT is not considered an application of a safety service as per ITU Radio 
Regulations, Article No. 1.59;
442
3) the peak EIRP density of a telemetry transmitter antenna shall
not exceed ?2.2 dB(W/MHz); 4) transmissions are limited to designated flight test areas, where flight test 
areas are airspace designated by administrations for flight testing; 5) bilateral coordination of transmitting 
AMT aircraft stations with respect to receiving fixed or mobile stations is required if the AMT aircraft 
station will operate within 450 km of the receiving fixed or mobile stations of another administration;
443

See United States of America Proposals for the Work of the Conference, plenary meeting, Document 5-E, 
February 9, 2007 (U.S. Proposals for WRC-07), Agenda Item 1.5, at 9-23.  See also CPM-07 Report, Chapter 1, at 
43-88.
438
The U.S. Proposals noted that newer technologies are relying increasingly on high-resolution video for 
monitoring aircraft functions or increased use of computer-based aircraft systems.  Under the U.S. position, without 
access to additional spectrum, aeronautical development could be subject to escalating delays and costs and the 
growth of aerospace industry would be significantly impaired (including equipment manufacturers, civilian 
programs and test ranges, and airlines).  See U.S. Proposals for WRC-07, Agenda Item 1.5, at 9.
439
Prior to WRC-07, the basic allocation structure in the International Table was as follows.  The 4400-4940 MHz 
and 5925-6700 MHz bands were allocated to the fixed and mobile services, and the 4500-4800 MHz and 
5925-6700 MHz bands were also allocated to the fixed-satellite service (Earth-to-space), on a primary basis in all 
ITU Regions.  At that time, however, RR 5.442 stated that in the 4825-4835 MHz band, the allocation to the mobile 
service was restricted to the mobile, except aeronautical mobile, service.  WRC-07 revised RR 5.442 to allocate the 
4825-4835 MHz band to the aeronautical mobile service on a primary basis in ITU Region 2, limited to AMT for 
flight test transmissions from aircraft stations.
440
See ITU Radio Regulations, Volume III, Resolution 416 (WRC-07), titled “Use of the bands 4400-4940 MHz and 
5925-6700 MHz by an aeronautical mobile telemetry application in the mobile service.” 
441
Further, these footnotes state that AMT use does not preclude the use of the 4400-4940 MHz and 5925-6700 
MHz bands by other mobile service applications or by other services to which these bands are allocated on a co-
primary basis and does not establish priority in the Radio Regulations.
442
ITU Radio Regulations, Article No. 1.59 defines a safety service as “any radiocommunication service used 
permanently or temporarily for the safeguarding of human life and property.”  See U.S. Proposals for WRC-07, 
Agenda Item 1.5, pp. 14-15 (draft Resolution [AMT4-6 GHz]).  We note that Resolution 416 generally mirrors the 
U.S. proposed resolution, except that WRC-07 resolved that AMT use in the two bands referenced above “is not 
considered an application of a safety service as per No. 1.59.”
443
Resolution 416 describes the following procedures for establishing whether a fixed or mobile service receiver in 
a neighboring administration and within 450 km of the flight test area will not receive an unacceptable level of 
interference: 1) determine if the receiving fixed or mobile station’s antenna main-beam axis, out to a distance of 
450 km, passes within 12 km of the designated area used by transmitting AMT aircraft stations, where this distance 
is measured orthogonally from the main-beam axis projection on the Earth’s surface to the nearest boundary of the 
projection of the flight test area on the Earth’s surface; 2) if the main-beam axis does not intersect the flight test area 
(continued….)
Federal Communications Commission FCC 15-50
75
and 6) require the use of technical and/or operational measures where appropriate to facilitate sharing 
with other services and applications in these bands.
444
209. Though the Commission did not propose in the WRC-07 NPRM to allocate spectrum for 
AMT use in the nearly exclusive Federal band at 4400-4940 MHz,
445
or in the exclusive non-Federal band 
at 5925-6700 MHz, we are now seeking comment on the ability of Federal/non-Federal AMT stations to 
share spectrum with the incumbent services in these bands.
446
  We believe that it is appropriate to examine 
the sharing potential in these bands based on input from NTIA regarding the interference mitigation 
techniques that could be used to promote such sharing.
447
  In doing so, we note that NTIA intended for the 
4400-4940 MHz and 5925-6700 MHz bands to be considered together as a “package” proposal.
448
  By 
making this additional spectrum available for both Federal and non-Federal AMT use, NTIA believes 
enough spectrum could be coordinated with the existing allocated services throughout all the bands to 
support additional AMT operations.
449
  In its supplement, NTIA clarified that if the 5925-6700 MHz band 
was not allocated for AMT use, then nearly all additional Federal AMT operations would be forced to use 
any capacity available in the 4400-4940 MHz band.
450
  As a result, the 4400-4940 MHz band would be 
fully utilized by Federal AMT operations, and NTIA indicated that it would no longer support a 
non-Federal AMT allocation in the 4400-4940 MHz band.
451
210. In light of NTIA’s concerns and recommendations, we specifically request comment on 
the proposed allocations for both the 4400-4940 MHz and 5925-6700 MHz bands.  In particular, are there 
technical approaches, coordination procedures, or analytical techniques that would ensure compatibility 
with existing services in these bands?  What are the costs and benefits and advantages or disadvantages of 
(Continued from previous page)                                                           
or any point within the 12 km offset, the interference could be accepted.  Otherwise, further bilateral coordination 
discussions would be needed.
444
See ITU Radio Regulations, Resolution 416 (WRC-07), resolves 1 and 2.  See also NTIA Final Supplement at 
4-5 (NTIA states that the operational restrictions contained in Resolution 416 were a result of cooperation and 
collaboration between the Department of Defense (DoD), the National Aeronautics and Space Administration 
(NASA), and FSS industry representatives, which the U.S. agreed as being able to protect FSS uplink satellite 
receivers and result in minimal interference to the FSS (e.g., less than a 3 percent increase in the satellite receiver 
noise level).  NTIA further states that the operational restrictions in Resolution 416, in conjunction with measures 
that can be employed by AMT operators, were developed in cooperation with FS industry participants in the ITU-R, 
and the U.S. agreed these measures should enable sharing between AMT and the FS users in the band.  NTIA  
recognizes that the burden of avoiding interference to the existing FS stations would primarily be on the AMT users, 
but anticipates that both AMT and FS operators would work together to resolve compatibility challenges.).

447
See NTIA Final Supplement at 5 (NTIA states that analysis conducted by the DoD and NASA prior to WRC-07 
demonstrated that through a combination of co-frequency avoidance and spatial isolation, it would be possible to 
find significant amounts of useable spectrum for AMT operations even in heavily congested areas of FS use.  
Furthermore, interstitial use of unused spectrum between FS channels may enable access to additional spectrum for 
AMT use.  Although the first two techniques are commonplace interference avoidance technologies, interstitial use 
of spectrum between FS channels may require development of AMT systems that employ more advanced 
technologies and capabilities so that enough spectrum could be consolidated to allow AMT access to spectrum with 
sufficient bandwidth.  While NTIA believes co-channel avoidance and spatial isolation techniques would initially be 
the primary means to achieve compatible operations between AMT and FS operations, as more advanced AMT 
technologies are developed, it may be possible to coordinate interstitial AMT operation between the FS channels.).

adding AMT allocations to these bands?  Is sharing with AMT the highest valued use of this spectrum or 
should we consider other potential licensed or unlicensed uses on a shared basis? 
1. 5925-6700 MHz
211. In the U.S. Table, the 5925-6700 MHz band is allocated exclusively for non-Federal use.  
This 775 megahertz of spectrum is allocated to the fixed-satellite service (FSS) (Earth-to-space) on a 
primary basis.
452
  In addition, the 5925-6425 MHz and 6525-6700 MHz bands are allocated to the fixed 
service (FS) on a primary basis, and the 6425-6525 MHz band is allocated to MS on a primary basis.
212. Frequencies in the 5925-6700 MHz band are available for assignment to transmitting 
earth stations
453
and to the Part 101 Fixed Microwave Services.
454
  Part 101 uses include common carrier, 
business, industrial, police, fire, utility, and transportation system operations.  In addition, frequencies in 
this band are used to provide wireless backhaul capacity, which is vital for the deployment of competitive 
wireless broadband services.
455
  Specifically, these frequencies are available under Part 101 to eligible 
entities in the: 1) Private Operational Fixed Point-to-Point Microwave Service (OFS) (5925-6875 MHz); 
2) Common Carrier Fixed Point-to-Point Microwave Service (CC) (5925-6425 MHz and
6525-6875 MHz); and 3) Local Television Transmission Service (LTTS) (5925-6525 MHz).
456
  In 
addition, frequencies in the 6425-6525 MHz band may be licensed to television broadcast auxiliary 
service (BAS) and cable television relay service (CARS) stations.
457
213. The 5925-6700 MHz band is used extensively for FS, FSS, and MS operations, including
earth stations on vessels.
458

Section 101.147(j) limits the use of the 6425-6525 MHz band to stations in the mobile service.  This band is 
co-equally shared with mobile stations licensed under Parts 74 and 78 of the Commission’s rules.

of Proposed Rulemaking, Second Notice of Inquiry, Order on Reconsideration, and Memorandum Opinion and 
Order, 27 FCC Rcd 9735 (2012).  In that action, the Commission, inter alia, modified the antenna standards set 
forth in its rules to permit the use of smaller antennas in the 5925-6875 MHz band, resulting in wider beamwidth 
signals.  In addition, the Commission revised its rules to permit FS operators to combine adjacent channels in the 
5925-6425 MHz band to form 60 megahertz wide channels (instead of the previous limit of 30 megahertz).  We note 
that the studies undertaken to support the U.S. position for WRC-07 regarding AMT operations may show different 
results if they are performed using these new parameters as inputs.  27 FCC Rcd at 9745, para. 18, and 9756,

214. NTIA recommends that we allocate the 5925-6700 MHz band to the AMS on a primary 
basis for Federal use; allocate the 5925-6425 MHz and 6525-6700 MHz bands to the AMS on a primary 
basis for non-Federal use;
462
and add the 5925-6700 MHz band to footnote US111.
463
  NTIA also 
recommends that we adopt the following U.S. footnote for operational criteria:
464
USXX3 [1.5] Use of the band 5925-6700 MHz by aeronautical mobile telemetry (AMT) for flight 
testing by aircraft stations (see No. 1.83) shall be in accordance with Resolution 416 (WRC 07).  
Any such use does not preclude the use of these bands by other non-federal mobile service 
applications or by other services to which these bands are allocated on a co-primary basis and 
does not establish priority.  Federal use of the aeronautical mobile service allocation in the band 
5925-6700 MHz is limited to aeronautical mobile telemetry for flight test telemetry transmissions 
by aircraft stations within designated test areas (See US111).
New footnote US111, adopted in the companion WRC-07 R&O, identifies the designated flight test areas.
215. The U.S. Proposals noted that there is a growing need for access to spectrum to support 
AMT operations.
465
  They recognized that the increased complexity and sophistication of modern aircraft 
necessitates monitoring an ever growing array of sensors and transmitting their data in real time for both 
safety purposes and helping to control the high costs of conducting flight tests.  Working collaboratively 
with the federal government and AMT stakeholders will allow for identifying various ways to support 
these needs, including exploring possible future use of other wireless services to augment the U.S.’s
existing AMT capabilities.
                                                     
459
The link count for Parts 101 and 74 is from the ULS_Micro data set (March 1, 2015), the link count for Part 78 is 
from the COALS data set (August 7, 2014), and the number of transmitting fixed earth stations authorized pursuant 
to Part 25 is from the IBFS data set (March 2, 2015).  The COALS data set is no longer being updated. 
460
In May 2011, the total number of fixed and mobile links in the 5925-6875 MHz band was 61,604.
461
We note that, under the Part 101 rules, channels in the 6525-6700 MHz band (175 megahertz of spectrum) are 
paired with channels in the 6700-6825 MHz band (175 megahertz).  Thus, the requested AMT allocation (i.e., 
co-primary status) would impact future fixed stations in 350 megahertz of spectrum, not just the requested 
175 megahertz.
462
The 6425-6525 MHz band is already allocated to the non-Federal MS on a primary basis.
463
NTIA’s recommended version of footnote US111 pertains to the 4400-4940 MHz, 5091-5150 MHz, and 
5925-6700 MHz bands.  However, as adopted in the companion WRC-07 R&O, this U.S. footnote pertains only to 
AMT use of the 5091-5150 MHz band.  See NTIA WRC-07 Recommendations at p. 4, footnote USXX5 [1.5], for 
NTIA’s recommended text.
464
See NTIA WRC-07 Recommendations at pp. 3-4 for the text of footnote USXX3 [1.5].  We have updated 
NTIA’s recommended text by replacing the cross reference to footnote “USXX5[1.5]” with “US111.”

216. We note that the underlying assumptions in the U.S. Proposals for WRC-07 included 
frequency avoidance or other measures to ensure compatible operations between AMT and incumbent 
services, such as requiring use of technical and/or operational measures on AMT. 
466
  Accordingly, it 
would be incumbent on the AMT community to develop techniques that will enable sharing without 
causing harmful interference to existing stations.  These techniques could include frequency coordination, 
shared network architectures, dynamic selection of operating frequencies, or spectrum use only in specific 
geographic areas.  It is not necessary at this time to determine the technical details for such sharing.  It is 
only necessary that we determine whether sharing is feasible.  To that end, we seek comment on the 
underlying assumptions made in Report ITU-R M.2119 which concluded that sharing is feasible.
467
  Also, 
we solicit comment as to what measures might be necessary to ensure the protection from harmful 
interference of incumbent non-Federal stations in the band.
468
  How may we best facilitate collaboration 
between Federal and non-Federal AMT users and incumbent services to determine appropriate technical 
conditions for sharing?  We also seek comment on whether increased sharing among non-Federal and 
Federal fixed microwave users in the 6-7 GHz range of spectrum could provide greater spectral 
efficiencies that would enable more usable bandwidth for both categories of fixed microwave users and 
for AMT.  We observe that other industry-government collaboration efforts have led to highly successful 
outcomes, such as in the recent reallocation and sharing of spectrum to support Advanced Wireless 
Service operations in the 1695-1710 MHz and 1755-1780 MHz bands.
469
217. The NTIA recommendations do not specify how AMT operations would share the 
6425-6525 MHz band with the non-Federal mobile service.  We seek comment on whether sharing this 
band with AMT is feasible. In considering whether to allocate the 6425-6525 MHz band for AMT use, 
we solicit comment on how the current mobile service assignments in this band are used.  For example, is 
land mobile use of this band generally limited to metropolitan areas?  Are there any aeronautical mobile 
applications, e.g., electronic newsgathering (ENG) operations from helicopters, in this band?
218. Finally, we request comment on several coordination issues. First, should the 
Commission use the existing process for coordinating federal authorizations for service with the FCC or 
should the Commission and NTIA jointly designate a third party coordinator to be responsible for 
coordinating AMT operations in the 5925-6700 MHz band?  Use of a third party coordinator may better 
protect incumbent operations, increase the speed of service, and provide non-Federal incumbents with an 
enhanced level of transparency during the coordination process. Second, is the information provided in 
footnote US111 with the coordinates for the 17 locations where flight testing would occur sufficient to 
ensure that AMT coordination with existing services in the 5925-6700 MHz band would be successful or 
is additional information needed?
                                                     
466
See ITU Radio Regulations, Resolution 416 (WRC-07), resolves 2.  See also U.S. Proposals for WRC-07, 
Agenda Item 1.5, at 10 (“It is expected that the implementation of telemetry may require avoiding co-frequency 
operations with local services in some of the bands.  This will likely mean that the spectrum requirement for AMT 
would be satisfied using portions of each of the bands studied and deemed suitable for AMT implementation.”).
467
See Report ITU-R M.2119 (2007), titled “Sharing between aeronautical mobile telemetry systems for flight 
testing and other systems operating in the 4 400-4 940 and 5 925-6 700 MHz bands.”
468
For example, Report ITU-R M.2119 states that for protection of FSS space station receivers in the 
5925-6700 MHz band, AMT use of this band should be limited to a maximum of 21 simultaneous co-frequency 
transmissions, including those from AMT stations authorized by other administrations.  In addition, this report found 
that “[p]ermissible levels of interference to FS/MS stations are not exceeded when the distance along the main-beam 
axis from the FS/MS antenna to the AMT area of operation is larger than 450 km or when the main-beam axis of the 
FS/MS antenna is separated from the aircraft flight zone by 12 km or more.”  See Report ITU-R M.2119 at 2, 4.

2. 4400-4940 MHz
219. In the U.S. Table, the 4400-4940 MHz band is allocated to the FS and MS on a primary 
basis for Federal use.
470
  The 4500-4800 MHz band is also allocated to the FSS (space-to-Earth) on a 
primary basis for non-Federal use
471
and the 4825-4835 MHz sub-band may be used for radio astronomy 
observations.
472
220. NTIA recommends that we allocate the 4400-4940 MHz band to the AMS on a primary 
basis for non-Federal use, amend footnote US111 to add the 4400-4940 MHz band, and add the two 
footnotes shown below to the Allocation Table to ensure compatible operations between non-Federal and 
Federal users in the band.
USXX2 [1.5] Use of the band 4400-4940 MHz by aeronautical mobile telemetry (AMT) for flight 
testing by aircraft stations (see No. 1.83) shall be in accordance with Resolution 416 (WRC 07).  
Any such AMT use does not preclude the use of these bands by other federal mobile service 
applications or by other services to which these bands are allocated on a co-primary basis and 
does not establish priority. Non-federal use of the aeronautical mobile service allocation in the 
band 4400-4940 MHz is limited to aeronautical mobile telemetry for flight test telemetry 
transmissions by aircraft stations within designated test areas (See US111).
USXX4 [1.5] Aeronautical Mobile Telemetry (AMT) operations will, as much as practicable, 
avoid transmitting in the band 4825-4835 MHz, used for radio astronomy observations of the 
formaldehyde line, when within line-of-sight of radio astronomy observatories included in the 
Table below.  AMT operations, conducted within 500 km of a radio astronomy observatory other 
than a Very Long Baseline Array (VLBA) station, or within 200 km of a VLBA station will, as 
much as practicable, share their schedule and consult with affected radio astronomy observatories 
through the Electromagnetic Spectrum Management office of the National Science Foundation 
(esm@nsf.gov).

Typical Federal uses include, but are not limited to, point-to-point microwave, drone vehicle control, and 
telemetry.
471
Although the 4500-4800 MHz band has also been allocated in the U.S. Table to the FSS (space-to-Earth) on a 
primary basis for non-Federal use since 1984, this FSS allocation has never been used.  Footnote US245 states that 
the non-Federal FSS (space-to-Earth) operations in the 4500-4800 MHz are limited to international inter-continental 
systems and are subject to case-by-case electromagnetic compatibility analysis. 
472
Specifically, footnote US113 identifies the radio astronomy stations that observe in the 4825-4835 MHz band and 
states that every practicable effort will be made to avoid the assignment of frequencies to stations in the fixed or 
mobile services in this band.  In the companion WRC-07 R&O, we revised footnote US203 and renumbered it as 
US113.  See para. 134, supra.

221. We seek comment on NTIA’s proposals for the 4400-4940 MHz band.  In particular, are 
there any additional measures that we should consider to ensure that AMT stations in the 4400-4940 MHz 
band would operate compatibly with public safety fixed and mobile operations in the adjacent 
4940-4990 MHz band?  Finally, if the 4400-4940 MHz band were allocated for use by non-Federal AMT 
licensees, any non-Federal AMT use would be coordinated with Federal agencies through NTIA’s 
Frequency Assignment Subcommittee process.  We seek comment on this assumption.
D. Additional Aviation Services Uses in the 5000-5150 MHz Band
222. In this section, we propose to take actions in support of aeronautical mobile (R) service 
(AM(R)S) surface applications at airports in the 5000-5030 MHz band and unmanned aircraft systems
(UAS) in the 5030-5091 MHz band.
473
223. Background.  Prior to WRC-12, the bands comprising the 5000-5150 MHz range were 
allocated in the International Table to the aeronautical mobile-satellite (R) service (AMS(R)S) on a 
primary basis, per RR 5.367.
474
  Additional allocations include the aeronautical radionavigation service 
(ARNS) (5000-5150 MHz, primary in all Regions) and the radionavigation-satellite service (RNSS) 
(5000-5030 MHz, primary in all Regions).
475
  In addition, RR 5.444 states that the 5030-5150 MHz band 
is to be used for the operation of the Microwave Landing System (MLS) for precision approach and 
landing.
476
  The 5091-5150 MHz band was also allocated to the aeronautical mobile service, limited by 
RR 5.444B, and the fixed-satellite service (Earth-to-space) (FSS) on a primary basis (RR 5.444A).
477
224. In the United States, the allocations in the bands comprising the 5000-5150 MHz range 
generally mirror the International Table as it existed prior to WRC-12.  All of these radio services, except 
the FSS, are allocated for Federal and non-Federal use.  The FSS is allocated exclusively for non-Federal 
use.
225. The United States proposed that WRC-12 allocate the 5030-5091 MHz band to the 
AM(R)S on a primary basis in order to support line-of-sight control links for unmanned aircraft.  In 
support of its proposal, the U.S. described the anticipated growth of unmanned aircraft systems (UAS) 
to include flight operations that will take place outside of segregated airspace.  It also discussed how the 
5030-5091 MHz band is an appropriate band to satisfy the terrestrial, line-of-sight, spectrum 
requirements for the command and control of UAS in non-segregated airspace g iven  tha t  there is 
minimum use in this band worldwide and because the lack of an existing or planned microwave
landing system deployment in the United States at 5030-5091 MHz ensures availability of appropriate
aeronautical spectrum for terrestrial line-of-sight UAS in the band.
478

See CPM Report to WRC-12, Chapter 1, Agenda Items 1.3 and 1.4, pp. 3-14, 20-23, 25, and 33-39; and WRC-12 
References, Resolutions 420 and 421 (WRC-07), pp. 54-59.
474
Prior to WRC-12, RR 5.367 read as follows: “Additional allocation:  The bands 1610-1626.5 MHz and 
5000-5150 MHz are also allocated to the aeronautical mobile-satellite (R) service on a primary basis, subject to 
agreement obtained under No. 9.21.”
475
In the 5000-5010 MHz band, the use of the RNSS allocation was limited to Earth-to-space transmissions, i.e., 
RNSS (Earth-to-space), and in the 5010-5130 MHz band, use was limited to space-to-Earth and space-to-space 
transmissions, i.e., RNSS (space-to-Earth) (space-to-space).
476
In the 5030-5091 MHz band, MLS requirements take precedence over other uses of this band.
477
We provide additional background on the 5091-5150 MHz band in the WRC-07 R&O, above.
478
See U.S. Proposals for WRC-12, First Tranche, Agenda Item 1.3.
Federal Communications Commission FCC 15-50
81
226. Consistent with the U.S. proposal, WRC-12 allocated the 5030-5091 MHz band to the 
AM(R)S on a primary basis in all Regions.  WRC-12 also adopted RR 5.443C, which limits the use of 
this AM(R)S allocation to internationally standardized aeronautical systems and which also limits 
unwanted emissions from stations in the AM(R)S that transmit in the 5030-5091 MHz band to an interim 
EIRP density value in the 5010-5030 MHz band.
479
227. WRC-12 moved the primary AMS(R)S allocation in the 5000-5150 MHz band from 
RR 5.367 and directly listed this allocation in the International Table.  WRC-12 limited the use of this
AMS(R)S allocation to internationally standardized aeronautical systems by adopting two international 
footnotes (RR 5.443AA and RR 5.443D), which also specify coordination requirements.  Specifically, 
WRC-12 maintained the existing coordination requirement for AMS(R)S systems operating in the 
5000-5030 MHz and 5091-5150 MHz bands (RR 5.443AA),
480
and revised the coordination requirement 
in the 5030-5091 MHz band to “give a balanced status between the two aviation services [i.e., AMS(R)S 
and AM(R)S] in this band” (RR 5.443D).
481
  NTIA recommends that we implement this action by directly 
listing a primary AMS(R)S allocation for Federal and non-Federal use in the 5000-5150 MHz bands, and 
that we limit the use of these allocations by adding the references to RR 5.443AA and RR 5.443D.
482
NTIA also recommends that we implement WRC-12’s AM(R)S allocation in the 5030-5091 MHz band
on a primary basis for Federal and non-Federal use, and that we add a reference to RR 5.443C to the U.S. 
Table.
228. NTIA further recommends that we also allocate the 5000-5010 MHz and 
5010-5030 MHz bands to the AM(R)S on a primary basis for Federal and non-Federal use.  Specifically, 
NTIA recommends that we add an entry for the AM(R)S in the 5000-5010 MHz band of the U.S. Table. 
For the 5010-5030 MHz band, it recommends that we adopt a new U.S. footnote allocating the band to 
the AM(R)S for requirements that cannot be met in the 5000-5010 MHz and 5091-5150 MHz bands.
483
                                                     
479
RR 5.443C reads as follows:  “The use of the frequency band 5030-5091 MHz by the aeronautical mobile (R) 
service is limited to internationally standardized aeronautical systems.  Unwanted emissions from the aeronautical 
mobile (R) service in the frequency band 5030-5091 MHz shall be limited to protect RNSS system downlinks in the 
adjacent 5010-5030 MHz band.  Until such time that an appropriate value is established in a relevant ITU-R 
Recommendation, the e.i.r.p. density limit of -75 dBW/MHz in the frequency band 5010-5030 MHz for any 
AM(R)S station unwanted emission should be used.”
480
RR 5.443AA reads as follows:  “In the frequency bands 5000-5030 MHz and 5091-5150 MHz, the aeronautical 
mobile-satellite (R) service is subject to agreement obtained under No. 9.21.  The use of these bands by the 
aeronautical mobile-satellite (R) service is limited to internationally standardized aeronautical systems.”
481
Specifically, WRC-12 replaced the coordination requirement for AMSRS systems in the 5030-5091 MHz band 
from No. 9.21 by No. 9.11A.  For a discussion of this issue, see ICAO Working Paper, ACP-WGF24/WP-06, 21 
March 2011, Agenda Item 1.3 and Annex.  RR 5.443D reads as follows: “In the frequency band 5030-5091 MHz, 
the aeronautical mobile-satellite (R) service is subject to coordination under No. 9.11A.  The use of this frequency 
band by the aeronautical mobile-satellite (R) service is limited to internationally standardized aeronautical systems.”
482
See NTIA WRC-12 Implementation Recommendations, p. 15 (table entries and footnotes in the 5000-5010 MHz, 
5010-5030 MHz, 5030-5091 MHz, and 5091-5150 MHz bands) and p. 26 (footnote US[5010-5030 MHz]).
483
NTIA’s recommended footnote (US[5010-5030 MHz]) reads as follows:  The band 5010-5030 MHz is also 
allocated to the aeronautical mobile (R) service (AM(R)S) limited to stations operating in accordance with 
international civil aviation standards and supporting surface applications at airports.  In making assignments for this 
band, attempts shall first be made to satisfy the AM(R)S requirements in the bands 5000-5010 MHz and 
5091-5150 MHz.  AM(R)S systems used in the band 5010-5030 MHz shall be designed and implemented to be 
capable of operational modification if receiving harmful interference from the radionavigation-satellite service.  
Finally, notwithstanding Article 4, No. 4.10, stations in the AM(R)S operating in this band shall be designed and 
implemented to be capable of operational modification to reduce throughput and/or preclude the use of specific 
frequencies in order to ensure protection of radionavigation-satellite service systems operating in the band 
5010-5030 MHz.  During the coordination process, NTIA informed us that its recommended text should be clarified 
to state that the AM(R)S in the 5010-5030 MHz would be allocated on a primary basis.    
Federal Communications Commission FCC 15-50

NTIA’s recommendations are consistent with a recent ICAO document, which states that “[t]he 
aeronautical mobile (R) service in the band 5091-5150 MHz is reserved for airport surface 
communication systems (AeroMACS) which are currently being developed.  A tuning range of 
5000-5150 MHz for AeroMACS is being considered to support either Regional or sub-Regional 
requirements.”
484
  Subsequently, NTIA revised its recommendations to include a U.S. footnote that would 
authorize on a primary basis fixed communications that are an integral part of the AeroMACS system in 
the 5000-5010 MHz and 5010-5030 MHz bands.
485
  Finally, we note that the FAA recently proposed to 
amend its regulations to allow the operation of small UAS in the National Airspace System.
486
229. Proposal.  Consistent with NTIA’s request, we propose to allocate spectrum to the 
AM(R)S to support line-of-sight control links for unmanned aircraft and, as discussed below, to provide 
additional spectrum for AeroMACS.
487
  First, we propose to add a primary AM(R)S allocation in the 
5030-5091 MHz band for Federal and non-Federal use, and to add a reference to RR 5.443C in the U.S. 
Table as NTIA requested.  We expect that addition of this AM(R)S allocation will help support the 
anticipated growth of UAS and promote the safe operation of UAS.  Further, adding RR 5.443C will limit 
AM(R)S use of the 5030-5091 MHz band to internationally standardized aeronautical systems and help 
protect adjacent-band RNSS downlinks by limiting the unwanted emissions of AM(R)S stations 
authorized under this allocation to an EIRP density of -75 dBW/MHz in the 5010-5030 MHz band.
230. Second, we propose to allocate the 5000-5030 MHz bands to the AM(R)S on a primary 
basis for Federal and non-Federal use, limited to surface applications at airports that operate in 
accordance with international aeronautical standards (i.e., AeroMACS).  Consistent with our action in the 
5091-5150 MHz band, we propose to permit aeronautical fixed communications that are an integral part 
of the AM(R)S system to be authorized in the 5000-5030 MHz band on a primary basis.  We would 
implement these proposals by adding an entry for the primary AM(R)S allocation to the 5000-5010 MHz 
band within the U.S. Table and by adding a new U.S. footnote, which we tentatively number as US115, to 
the 5000-5010 MHz and 5010-5030 MHz bands.  Proposed footnote US115 contains the primary 
AM(R)S allocation for the 5010-5030 MHz band, limits the use of this allocation to those AeroMACS 
requirements that cannot be satisfied in the 5000-5010 MHz and 5091-5150 MHz bands, specifies the 
additional limitations, and authorizes the primary fixed use discussed above.
488
  In the WRC-07 R&O, 
above, we made the 5091-5150 MHz band available for AeroMACS.  The 5091-5150 MHz band is 
globally harmonized and it is expected to be the main frequency band for deployment of AeroMACS.  
Today’s proposals would extend the tuning range for AeroMACS to include the 5000-5010 MHz and 
5010-5030 MHz bands in the United States.  Given that “ITU-R studies conclude that the total identified 
spectrum requirement to support surface applications at airports is 130 MHz,”
489
we believe that there is a 
need for this additional spectrum.

231. Third, we propose to add entries in the U.S. Table for the primary AMS(R)S allocation in 
the frequency range 5000-5150 MHz.  Because these bands are already allocated to the AMS(R)S through 
footnote US367, we would only be acting to highlight an existing allocation.
490
  We also propose to add 
references to two international footnotes (RR 5.443AA, RR 5.443D) in the U.S. Table.
491
  We note that 
both of these footnotes also contain a new requirement: the use of the AMS(R)S in the 5000-5150 MHz 
range would be limited to internationally standardized aeronautical systems.
232. We seek comment on our proposals.  Table 5, below, reflects the 5000-5150 MHz range 
as it will exist in the U.S. Table as a result of our actions herein, and our proposed amendments to these 
bands.

Consequently, footnote US367 would be removed from the Allocation Table.  See para. 61, supra.  We note that 
an ICAO report has stated that “AMS(R)S is the appropriate type of service allocation to support the satellite 
component for UAS command and control and ATC relay in non-segregated airspace.”  We also note that an ICAO 
report has stated no AMS(R)S satellite system currently operates in the 5000-5150 MHz range to support 
current/near-term UAS CNPC.  See ICAO Report, dated Sept. 26, 2012, from the “Aeronautical Communications 
Panel (ACP), Twenty Seventh Meeting of Working Group F” (ACP-WGF27 Report) at 27-28.
491
The addition of RR 5.443AA to the right of the AMS(R)S allocation in the 5000-5010 MHz, 5010-5030 MHz, 
and 5091-5150 MHz bands would serve to maintain the existing coordination requirements in these bands; the 
addition of RR 5.443D to the right of the AMS(R)S allocation in the 5030-5091 MHz band would serve to change 
the coordination requirements in that band from ITU Radio Regulation No. 9.21 to 9.11A.
492
The entries under the heading “Existing U.S. Table” reflect these bands as shown in 47 C.F.R. § 2.106, Edition of 
2012, plus the following amendments that we make herein:  1) Replaced RR 5.367 with footnote US367 in para. 61, 
supra; and 2) Added the primary AMS allocation to the 5091-5150 MHz band, limited by footnotes US111 and 
US444B, in paras. 58-59.

E. Allocating the 22.55-23.15 GHz and 25.5-27 GHz Bands to the Space Research 
Service
233. In this section, we consider WRC-12’s decision to allocate the 22.55-23.15 GHz band to
the space research service (SRS) on a primary basis, restricted to operations in the Earth-to-space 
(uplink) direction.
493
234. Background.  Prior to WRC-12, the 22.55-23.55 GHz band was allocated to the fixed, 
mobile, and inter-satellite services on a primary basis in all ITU Regions.  RR 5.338A states that 
Resolution 750 (WRC-07) applies to the use of the 22.55-23.55 GHz band by the inter-satellite service 
(ISS).  RR 5.149 states that, in making assignments to stations of other services to which the 
22.81-22.86 GHz and 23.07-23.12 GHz bands are allocated, administrations are urged to take all 
practicable steps to protect the radio astronomy service from harmful interference, and that emissions 
from spaceborne or airborne stations can be particularly serious sources of interference to the radio 
astronomy service.
235. In the United States, the 22.55-23.55 GHz band is Federal/non-Federal shared spectrum 
that is allocated to the fixed, mobile, and inter-satellite services on a primary basis.  Footnote US278 
states that non-geostationary inter-satellite links may operate on a secondary basis to geostationary 
inter-satellite links in this band.  The United States has implemented RR 5.149 as footnote US342.  In the 
WRC-07 R&O, we adopted new footnote US145 (in lieu of RR 5.338A).
494
236. The United States proposed that WRC-12 allocate the 22.55-23.15 GHz band to the space 
research service (Earth-to-space) on a primary basis, and provided a footnote regarding the location of 
SRS earth stations to protect the existing and future deployment of fixed and mobile services of 
neighboring administrations.
495
  In support of its proposal, the U.S. stated that there is a need for a
companion uplink (Earth-to-space) band to pair with the existing downlink 25.5-27 GHz SRS 
allocation that can provide the mission data, voice/video communications, and command and control
links to support manned and unmanned missions.  It stated that the proposed SRS allocation at 23 GHz
will fulfill this need for the global space science community.
496
  Finally, the U.S. noted that, considering
the inherently limited number of these large SRS earth stations and their remote locations, ITU-R
sharing studies determined that sharing between the proposed SRS (Earth-to-space) allocation a n d the
existing services in the 22.55-23.55 GHz band is feasible and would not cause harmful interference to
their existing operations.
237. WRC-12 allocated the 22.55-23.15 GHz band to the SRS (Earth-to-space) on a primary 
basis in all Regions.  WRC-12 also adopted RR 5.532A, which protects the existing and future 
deployment of the fixed and mobile services using similar text to that proposed by the United States.

496
The U.S. also made the following points:  First, space agencies require their own segments of spectrum for
lunar and many Lagrangian missions since antenna discrimination is not possible. Any spacecraft around the
moon and some of those with small orbit apogees around the L1 or L2 points can be situated within the
main-beam lobe of other space agency antennas.  Second, the specific RF carrier frequencies selected will often
be coupled with internationally agreed channels for data relay systems in order to provide global support either
via an earth station or via a data relay satellite. These data relay channels have a spacing of 60 megahertz,
irrespective of the actual bandwidth.  Third, there is a fixed turn-around ratio required between the Earth-to-space
link around 23 GHz and the corresponding space-to-Earth link in the 25.5-27 GHz band.  This is required for
ranging purposes and further limits the choice of available frequencies as it requires a suitable available
companion frequency around 26 GHz.
Federal Communications Commission FCC 15-50
85
NTIA recommends that we allocate the 22.55-23.15 GHz band to the SRS (Earth-to-space) on a primary 
basis for Federal use, and that we also add a reference to RR 5.532A in the Federal Table.
497
238. Proposal.  Consistent with WRC-12 and NTIA’s recommendation, we propose to modify 
the U.S. Table to allocate the 22.55-23.15 GHz band to the SRS (Earth-to-space) on a primary basis for 
both Federal and non-Federal use and to add a reference to RR 5.532A in the U.S. Table.  In addition, we 
propose to add a primary non-Federal SRS (space-to-Earth) allocation to the companion 25.5-27 GHz 
band, which currently is allocated to the SRS (space-to-Earth) only for Federal use.  We are proposing 
non-Federal SRS allocations to both of these bands in support of the National Space Policy, which 
encourages the development of a robust and competitive commercial space sector.
498
This action is 
consistent with the Commission’s proposal to make spectrum allocated for Federal exclusive use 
available for use by commercial space launch operators.
499
  Finally, we solicit comment on whether there 
is a need for us to expressly state that the use of the proposed allocations would be “at a limited number 
of sites.”
500
  We request comment on these proposals.
F. Passive and Weak Signal Issues
1. Deletion of Aeronautical Mobile Service from the 37-38 GHz Band
239. In this section, we consider WRC-12’s decision to limit the mobile service in the 
37-38 GHz band to the mobile except aeronautical mobile service.
501
240. Background.  Prior to WRC-12, the 37-38 GHz bands were allocated to the fixed service 
(FS), mobile service (MS), and space research service (SRS) (space-to-Earth) (downlink) on a primary 
basis in all ITU Regions.  The 37.5-40 GHz band was also allocated to the fixed-satellite service (FSS) 
(space-to-Earth) on a primary basis and to the Earth exploration-satellite service (space-to-Earth) on a 
secondary basis.  RR 5.547 states that the 37-40 GHz band is available for high-density applications in the 
fixed service (HDFS).
241. In the United States, the 37-38 GHz band is allocated to the FS and MS on a primary 
basis for Federal and non-Federal use and to the SRS (space-to-Earth) on a primary basis for Federal use.  
The 37.5-38 GHz band is also allocated to the FSS (space-to-Earth) on a primary basis for non-Federal 
use.
242. In its preparations for WRC-12, the United States observed that Administrations are
implementing SRS earth station receivers in the band 37-38 GHz to support manned missions for both 
near Earth and deep space missions, and that use of the wider bandwidth available in the 37-38 GHz
band is necessary to support the increasing data requirements of these planned manned missions.  
Accordingly, the U.S. proposed that WRC-12 adopt an international footnote that would protect SRS and 
                                                     
497
See NTIA WRC-12 Implementation Recommendations, p. 18 (where the common U.S. Table entry for the 
22.55-23.55 GHz band is subdivided into the Federal and non-Federal Tables, so that “SPACE RESEARCH (Earth-
to-space) 5.532A” can be added to the Federal Table).
498
See National Space Policy of the United States of America (June 28, 2010) at 3, 10-11 (available at

expresses the President’s direction for the nation’s space activities.

Spectrum for Non-Federal Space Launch Operations, ET Docket No. 13-115, Notice of Proposed Rulemaking and 
Notice of Inquiry, 28 FCC Rcd 6698 (2013).  This Notice also proposes to add Federal allocations to a number of 
commercial fixed-satellite service bands.

FSS earth stations and fixed stations in the 37-38 GHz band by the application of a power flux-density
(PFD) limit at the surface of the Earth on the emissions radiated by any device on an aircraft in flight
or on the ground.
502
243. The ITU studied sharing between systems in the SRS, FS, and FSS and potential
systems in the aeronautical mobile service (AMS) in the 37-38 GHz band. The sharing studies indicate
that high power emissions from typical aeronautical mobile transmitters would pose a high probability
for causing harmful interference to receiving SRS and FSS earth stations, but that lower powered
aircraft stations could be compatible, if they meet a specified PFD mask. These studies also found that 
transmissions from HDFS systems could interfere with the airborne receivers of the AMS.  WRC-12 
addressed use of the 37-38 GHz band by revising the primary mobile service allocation to exclude the 
AMS.  It did so by revising the “MOBILE” entry in the International Table to read “MOBILE except 
aeronautical mobile.”  NTIA recommends that we implement WRC-12’s decision by amending the 
Federal and non-Federal Tables to replace the primary mobile service allocation in the 37-38 GHz band 
with a primary mobile except aeronautical mobile service allocation.
503
244. Proposal.  As requested by NTIA, we propose to amend the U.S. Table by excluding the 
AMS from the 37-38 GHz band.  We request comment on this proposal.
2. Protecting Passive Sensors in the 86-92 GHz Band
245. In this section, we consider WRC-12’s actions relative to the fixed service in the 
81-86 GHz and 92-94 GHz bands.
504
246. Background.  The United States proposed that WRC-12 make no changes to the fixed
service in the bands between 71 GHz and 238 GHz because insufficient information is available to
substantiate specific out-of-band emission limits to protect the passive sensors that operate in the Earth 
exploration-satellite service (EESS) (passive) in the 86-92 GHz band and because the technologies
employed by the active services in these bands are still in the early stages of development.
505
247. While WRC-12 did not adopt mandatory protection requirements in the band, it did take 
steps to afford protection to passive services.  Specifically, WRC-12 revised Resolution 750 to urge 
administrations to take all reasonable steps to ensure that unwanted emissions of fixed stations in the 
81-86 GHz and 92-94 GHz bands do not exceed the recommended maximum levels contained in 
Table 1-2, and revised RR 5.338A by adding the 81-86 GHz and 92-94 GHz bands to the list of band to 
which Resolution 750 applies.  The recommended maximum level of unwanted emissions power 
(measured at the antenna port) is listed in Table 6, below:
                                                     
502
See U.S. Proposals for WRC-12, First Tranche, Agenda Item 1.12.  The U.S.-proposed footnote read as follows:  
In the band 37-38 GHz, the power flux-density at the Earth’s surface produced by emissions from an aircraft
station shall not exceed -227 dB(W/m
2
) in any 1 Hz bandwidth, using free space propagation conditions as
applied from the exterior of the aircraft.
503
See NTIA WRC-12 Implementation Recommendations, p. 19 (where “MOBILE except aeronautical mobile” is 
shown in the 37-38 GHz band within the Federal Table and in the 37-37.5 GHz and 37.5-38 GHz bands within the 
non-Federal Table).

248. NTIA recommends that we adopt two U.S. footnotes that replicate the WRC-12 
unwanted emissions levels for the 81-86 GHz and 92-94 GHz bands.
506
249. Proposal.  We propose to encourage operators of fixed stations transmitting in the 
81-86 GHz and 92-94 GHz bands to take all reasonable steps to ensure that their unwanted emissions
power in the 86-92 GHz passive band does not exceed WRC-12’s non-mandatory unwanted emissions
levels.  We also propose combining the text of NTIA’s recommended U.S. footnotes into a single 
footnote, which we tentatively number as US162.  See Appendix F for the text of proposed footnote 
US162.  We request comment on these proposals.
3. Passive Use of Bands Above 275 GHz
250. In Agenda Item 1.6, WRC-12 reviewed RR 5.565 to update the spectrum use by the 
passive services between 275 GHz and 3000 GHz.
507
  This international footnote provides a list of
frequency bands throughout the 275-1000 GHz range that have been identified for observations of 
spectral line emissions and spectral windows for the passive services.  Prior to WRC-12, the last entry in 
the International Table read as follows:  “275-1000 [GHz]   (Not allocated) 5.565.”
251. Background.  In its proposals to WRC-12, the United States asserted that passive and 
active services can share frequencies above 1000 GHz without constraints.
508
It noted that passive 
services such as the Earth exploration-satellite service (EESS), space research service (SRS), and radio 
astronomy service (RAS) already utilize portions of the 275-3000 GHz range for scientific observation, 
and that “it is important to recognize that this frequency range concurrently is used for experimentation 
with, and development of, an array of emerging active service applications.”
509
  It also noted the technical 
factors that influence use of the 275-3000 GHz range, such as how the Earth's atmosphere absorbs signals 
at these frequencies, especially in the 1000-3000 GHz range, and that antenna beamwidths are extremely 
narrow at such high frequencies.  It concluded that interference from non-geostationary satellites into 
terrestrial stations is highly unlikely, and that coordination of geostationary satellites would resolve any 
potential interference issues that might arise.
252. WRC-12 revised RR 5.565 to make changes to the bands identified for passive sensor 
use.
510
  RR 5.565 states that “Administrations wishing to make frequencies in the 275-1000 GHz range

92-94 GHz band).

available for active service applications are urged to take all practicable steps to protect these passive 
services from harmful interference until the date when the Table of Frequency Allocations is established 
in the above-mentioned 275-1000 GHz frequency range,” but does not impose mandatory protection 
criteria.  In addition, WRC-12 extended the International Table from 1000 GHz to 3000 GHz, and applied 
RR 5.565 to this larger frequency range.  NTIA recommends that we revise the text of RR 5.565 to reflect 
the revised list of bands identified for passive sensor use and that we extend the “not allocated” portion of 
the Table to 3000 GHz.
511
  Because WRC-12’s revision of RR 5.565’s text is a significant change that 
requires public comment, we have moved the pre-WRC-12 text of RR 5.565 into new footnote US565.
512
253. Proposal.  As requested by NTIA, we propose to extend the “not allocated” portion of the 
U.S. Table to 3000 GHz and to add a reference to the WRC-12 version of RR 5.565 to the new 
275-3000 GHz band.
513
  This action would update the spectrum identified for use by passive spaceborne 
sensors in the 275-1000 GHz range.  
254. We observe that, as a result of WRC-12’s action, 565 gigahertz – or 78 percent – of the 
725 gigahertz of spectrum in the 275-1000 GHz range has been identified for passive service applications 
in the International Table.
514
  However, we believe that it is important to recognize that this frequency 
range is used and may be used more extensively in the future for experimentation with, and development 
of, an array of active service applications.  We note that RR 5.565 should not be misconstrued as placing
a “reservation” for future passive service allocations in the U.S. Table, which would inhibit commercial 
development of this spectrum.  We encourage the development of active services in the 275-3000 GHz 
range under Part 5 of the rules.  While we continue to believe that it is premature to establish an allocation 
in the U.S. Table in this frequency range, we tentatively conclude that it is necessary to avoid spectrum 
use restrictions and maintain flexibility in our spectrum allocation decisions to support the development 
of new uses in the future.  Accordingly, we propose to adopt the following U.S. footnote:
US565 International footnote 5.565 does not establish priority of use in the United States Table 
of Frequency Allocations, and does not preclude or constrain the allocation of frequency bands in 
the range 275-3000 GHz to active services at a future date.
We seek comment on these proposals.
G. Proposals for New Federal Government Allocations
1. Allocating the 7850-7900 MHz Band to the Meteorological-Satellite Service
255. Background.  Prior to WRC-12, the 7750-7850 MHz and 7850-7900 MHz bands 
were allocated to the fixed and mobile except aeronautical mobile services on a primary basis in all 
ITU Regions. The 7750-7850 MHz band was also allocated the meteorological-satellite (MetSat) 
service for space-to-Earth transmissions (downlink use) on a primary basis in all Regions, limited to
non-geostationary satellite orbit (NGSO) systems.
515
                                                     
511
See NTIA WRC-12 Implementation Recommendations, p. 21 (depicting the expansion of the “not allocated” 
portion of the Allocation Table from 275-1000 GHz to 275-3000 GHz) and p. 24 (RR 5.565).
512
See WRC-12 Order, para. 142, supra.
513
In the WRC-12 Order, we replaced the reference to RR 5.565 in the U.S. Table with new footnote US565.  
Because we are proposing to reinsert the reference to RR 5.565 in the U.S. Table, we are reusing footnote US565 for 
the proposed U.S. footnote in the following paragraph.  
514
The following twelve bands (which total 160 gigahertz) are not identified for passive service applications: 
510-523 GHz, 527-538 GHz, 581-611 GHz, 711-713 GHz, 718-729 GHz, 733-750 GHz, 754-771 GHz, 
776-795 GHz, 945-951 GHz, 956-968 GHz, 973-985 GHz, and 990-1000 GHz.
515
See RR 5.461B.
Federal Communications Commission FCC 15-50
89
256. In the U.S. Table, these bands are allocated for exclusive Federal use.  Specifically, the 
7750-7850 MHz and 7850-7900 MHz bands are allocated to the Federal fixed service on a primary basis 
and the 7750-7850 MHz band is also allocated for primary Federal MetSat downlink use, limited to 
NGSO systems.
257. The United States proposed that WRC-12 add 50 megahertz to the current MetSat 
downlink allocation, with the existing NGSO system limitation extended throughout the resultant band 
(7750-7900 MHz).
516
In support of its proposal, the U.S. stated that additional spectrumwill be needed to
provide the necessary bandwidth for the next generation of NGSO meteorological satellites.  
Furthermore, the U.S. stated that the compatibility analyses between MetSat and the fixed services
concluded that the potential extension 7850-7900 MHz band can be shared under the same conditions
as the current 7750-7850 MHz allocation.
258. WRC-12 adopted this U.S. proposal.  Thus, in the International Table, the 
7750-7900 MHz band is allocated to the fixed, MetSat (space-to-Earth), and mobile except aeronautical 
mobile services on a primary basis.  The use of the MetSat allocation is restricted to NGSO systems by 
RR 5.461B, which WRC-12 applied to the new band.
259. Proposal.  NTIA recommends that the 7750-7900 MHz band be allocated to the fixed 
and MetSat (space-to-Earth) services on a primary basis for Federal use, and that RR 5.461B be listed 
in the Federal Table, thereby limiting MetSat use of this band to NGSO systems.
517
  We propose to 
modify the U.S. Table to reflect this approach.
2. Allocating the 15.4-15.7 GHz Band to the Radiolocation Service
260. Background.  Prior to WRC-12, the 15.4-15.43 GHz, 15.43-15.63 GHz, and 
15.63-15.7 GHz bands were allocated to the aeronautical radionavigation service (ARNS) on a primary 
basis in all ITU Regions. The 15.43-15.63 GHz band was also allocated to the fixed-satellite service 
(FSS) (Earth-to-space) on a primary basis, and per RR 5.11A, FSS use was limited to feeder links of 
non-geostationary systems in the mobile-satellite service (NGSO MSS feeder links).  FSS use is also 
permitted in the 15.4-15.43 GHz and 15.63-15.7 GHz bands for grandfathered systems (RR 5.511D).  
Sharing criteria for ARNS stations and NGSO MSS feeder link earth stations is specified in RR 5.511C.
261. In the United States, the 15.4-15.7 GHz band is allocated to ARNS on a primary basis for 
Federal and non-Federal use, and pursuant to footnote US260, aeronautical mobile communications that 
are an integral part of ARNS systems may also operate in the 15.4-15.7 GHz band.  The 15.43-15.63 GHz 
band is also allocated to the FSS (Earth-to-space) on a primary basis for non-Federal use, and, per 
footnote US359, FSS use is limited to NGSO MSS feeder links.  The sharing criteria in RR 5.511C 
applies.
262. The United States proposed that WRC-12 allocate the 15.4-15.7 GHz band to the 
radiolocation service (RLS) on a primary basis in all ITU Regions, on the basis that such an allocation 
would provide an increase in image resolution and range accuracy.
518
  In support of its proposal, the U.S.
noted that Resolution 614 (WRC-07) called for WRC-12 to consider a new primary RLS allocation in
the 15.4-15.7 GHz band to provide additional spectrum for new radar systems to increase image
resolution and range accuracy, and that these advanced radars require wider emission bandwidths than
are currently available.  The U.S. also proposed that WRC-12 limit the use of the RLS allocation to

protect other primary services in the band and the radio astronomy service in the adjacent
15.35-15.4 GHz band by adopting two international footnotes (later numbered as RR 5.511E and 
RR 5.511F) that protect incumbent services.
519
  RR 5.511E requires that RLS stations operating in the 
15.4-15.7 GHz band not cause harmful interference to, or claim protection from, ARNS stations.  
RR 5.511F requires that RLS stations operating in the 15.4-15.7 GHz band not exceed the power 
flux-density level of -156 dB(W/m
2
) in any 50 megahertz within the 15.35-15.4 GHz band, at any radio 
astronomy observatory site for more than 2 percent of the time.
263. WRC-12 adopted these U.S. proposals with only minor text changes to the proposed 
footnotes.
520
  NTIA recommends that the 15.4-15.7 GHz band be allocated to the RLS on a primary basis 
for Federal use and that RR 5.511E and RR 5.511F be added to the Federal Table.
521
  In addition, NTIA 
recommends that the following footnote be added to the Federal Table:
G135  The use of the band 15.4-15.7 GHz by the radiolocation service is limited to systems 
requiring necessary bandwidth of greater than 1600 MHz that cannot be fully accommodated 
within the band 15.7-17.3 GHz except as described below.  In the band 15.4-15.7 GHz, stations 
operating in the radiolocation service shall not cause harmful interference to, nor claim protection 
from, radars operating in the aeronautical radionavigation service.  Radar systems operating in the 
radiolocation service shall not be developed solely for operation in the band 15.4-15.7 GHz. 
However, radar systems that require testing, training, and exercises in the band 15.4-15.7 GHz 
shall be accommodated on a case-by-case basis.
264. Proposal.  As requested by NTIA, we propose to allocate the 15.4-15.7 GHz band to the 
RLS on a primary basis for Federal use and to add references to RR 5.511E and RR 5.511F to the Federal 
Table.  However, because the 15.4-15.7 GHz band is allocated for Federal/non-Federal shared use, and in 
particular because the new Federal RLS allocation would be required to protect existing and future 
non-Federal stations in the ARNS from harmful interference, we have reclassified footnote G135 as a 
U.S. footnote, which we tentatively numbered as US511E.
522
  We have also made minor changes to the 
text of proposed footnote US511E to improve its readability.  See Appendix F for the text of proposed 
footnote US511E.  If adopted, this proposal will provide the additional spectrum needed for new 
advanced radar systems and increase the image resolution and range accuracy of such systems.  We 
request comment on these proposals.
H. Other Matters
265. The 72-73 MHz and 75.4-76 MHz bands are allocated to the fixed and mobile services on 
a primary basis for non-Federal use.  Footnote NG49 identifies 30 frequencies from 72.02 MHz to 
75.60 MHz as being available to former Part 90 radio services, subject to the condition that no 
                                                     
519
The U.S. also stated that ITU-R studies demonstrated compatibility between the RLS and other services 
allocated in the 15.4-15.7 GHz band, noting that Report ITU-R M.2170 addresses compatibility between RLS and
radionavigation, FSS systems in this band and radio astronomy in the adjacent 15.3-15.4 GHz band.  The ITU-R
studies used technical characteristics and protection criteria of System 6 in Recommendation ITU-R M.1730 to
represent the radiolocation radars proposed for the 15.4-17.3 GHz band. Recommendation ITU-R M.l372
identifies interference mitigation techniques that ensure compatibility among radar systems operating in different 
radiodetermination services.  Additionally, Report ITU-R M.2076 contains further mitigation techniques for
interference from radiolocation radars into radionavigation radars operating in the 9 GHz band.

Table) and p. 27 (recommended footnote G135).

interference is caused to TV channels 4 and 5 reception.
523
These radio services are now part of the 
consolidated Industrial/Business Radio Pool.
524
Moreover, all 30 frequencies are listed in the 
Industrial/Business Pool Frequency Table, which is codified in Section 90.35 of the Commission’s 
rules.
525
We propose to update and simplify footnote NG49 and to renumber this footnote as NG16.  
Specifically, we propose to no longer list the individual frequencies within the footnote.  In addition, 
while the footnote describes pool-specific geographic limitations for all 30 frequencies (e.g., 
manufacturing facilities, railroad yards and mills), the Industrial/Business Pool Frequency Table only 
places geographic limits on the 10 frequencies from 72.44 MHz to 75.60 MHz, and uses the more 
generalized concept of “the licensee’s business premises.”
526
  We propose to remove the geographic 
restriction from footnote NG49 but retain the existing Part 90 rules.  Thus, the effect of our proposal is to 
make the Allocation Table consistent with the existing service rules.  The revised footnote, NG16, would 
read as follows:  In the bands 72-73 MHz and 75.4-76 MHz, frequencies may be authorized for mobile 
operations in the Industrial/Business Radio Pool, subject to the condition that no interference is caused to 
the reception of television stations operating on channels 4 and 5.  We seek comment on this proposal.
266. We propose to amend Section 2.100 of the rules to state that the ITU Radio Regulations, 
Edition of 2012, have been incorporated to the extent practicable in Part 2.
VII. PROCEDURAL MATTERS
A. Report and Order
267. Final Regulatory Flexibility Analysis.  As required by Section 603 of the Regulatory 
Flexibility Act, 5 U.S.C. § 603, the Commission has prepared a Final Regulatory Flexibility Analysis 
(IRFA) of the possible significant economic impact on small entities of the changes adopted in this 
document. The FRFA is set forth in Appendix E.
268. Paperwork Reduction Analysis. This document contains no new or modified 
information collection requirements subject to the Paperwork Reduction Act of 1995 (PRA), Public Law 
104-13. In addition, therefore, it does not contain any new or modified “information collection burden for 
small business concerns with fewer than 25 employees,” pursuant to the Small Business Paperwork Relief 
Act of 2002, Public Law 107-198, see 44 U.S.C. 3506(c)(4).
269. Congressional Review Act.  The Commission will send a copy of this Report and Order, 
Order, and WRC-12 Notice of Proposed Rulemaking to Congress and the Government Accountability 
Office pursuant to the Congressional Review Act, see 5 U.S.C. 801(a)(1)(A).
                                                     
523
Footnote NG49 lists 20 frequencies from 72.02 MHz to 72.40 MHz that may be authorized for mobile operations 
in the Manufacturers Radio Service and limits their use to a manufacturing facility.  It also lists 10 frequencies from 
72.44 MHz to 75.60 MHz that may be authorized for mobile operations in the Special Industrial Radio Service, 
Manufacturers Radio Service, Railroad Radio Service and Forest Products Radio Service and limits their use to a 
railroad yard, manufacturing plant, logging site, mill, or similar industrial facility.  We note that the 10 frequencies 
from 72.44 MHz to 75.60 MHz are also available to Public Safety Radio Pool licensees for fire call box operations.  
47 C.F.R. 90.20(d)(25).
524
This consolidation stems from the Commission’s ‘refarming’ proceeding (PR Docket No. 92-235), which 
combined the various Industrial Radio Services and Land Transportation Radio Services into a single 
Industrial/Business Radio Pool. 
525
The Industrial/Business Pool Frequency Table further identifies the 30 frequencies as being available for mobile 
stations, and states that all operations are subject to the provisions of another Part 90 rule (§ 90.257(b)) that sets 
forth criteria for protecting TV channel 4 and 5 reception.
526
This is specified by assignment limitation 77, reads as follows: All communications on this frequency must be 
conducted within the boundaries or confines of the licensee’s business premises.  47 C.F.R. § 90.35(b)(3), (c)(77).

and missiles, or their major components.  Until January 1, 2020, the 2345-2360 MHz band is also 
available to licensees holding a valid authorization on April 23, 2015 for these purposes on a secondary 
basis.  Permissible uses of these bands include telemetry and associated telecommand operations 
associated with the launching and reentry into the Earth's atmosphere, as well as any incidental orbiting 
prior to reentry, of objects undergoing flight tests.  In the 1435-1525 MHz band, the following 
frequencies are shared on a co-equal basis with flight telemetering mobile stations: 1444.5, 1453.5, 
1501.5, 1515.5, and 1524.5 MHz.  In the 2360-2395 MHz band, the following frequencies may be 
assigned for telemetry and associated telecommand operations of expendable and re-usable launch 
vehicles, whether or not such operations involve flight testing: 2364.5, 2370.5 and 2382.5 MHz.  All 
other mobile telemetry uses of the 2360-2395 MHz band shall be on a non-interfering and unprotected 
basis to the above uses.
(2) Frequencies in the 5091-5150 MHz band are assigned in the aeronautical mobile service on a 
primary basis for flight testing of aircraft.  AMT use of these frequencies is restricted to aircraft stations 
transmitting to aeronautical stations (AMT ground stations) in the flight test areas listed in 47 CFR 2.106, 
footnote US111.
(3) The authorized bandwidths for stations that operate in the 1435-1525 MHz, 2345-2395 MHz, or
5091-5150 MHz bands are normally 1, 3 or 5 MHz.  Applications for greater bandwidths will be 
considered in accordance with the provisions of § 87.135.  Each assignment will be centered on a 
frequency between 1435.5 MHz and 1524.5 MHz, between 2345.5 MHz and 2394.5 MHz, or between 
5091.5 MHz and 5149.5 MHz, with 1 MHz channel spacing.

APPENDIX E
Final Regulatory Flexibility Analysis
1. As required by the Regulatory Flexibility Act of 1980, as amended (RFA),
1
an Initial 
Regulatory Flexibility Analysis (IRFA) was incorporated in the Notice of Proposed Rulemaking in
ET Docket No. 12-338 (WRC-07 NPRM).
2
  The Commission sought written public comment on the 
proposals in the WRC-07 NPRM, including comment on the IRFA.  This present Final Regulatory 
Flexibility Analysis (FRFA) conforms to the RFA.
3
A. Need for, and Objectives of the Report and Order
2. In this Report and Order, the Commission amends Parts 1, 2, 25, 27, 74, 78, 80, 87, 90, 
97, and 101 of its rules to complete implementation of various allocation decisions from the Final Acts of 
the World Radiocommunications Conference (Geneva, 2007) (WRC-07) in the Commission’s Table of 
Frequency Allocations, to revise certain other allocations in the Table, and to update certain related 
service rules.  The decisions adopted in this Report and Order conform the Commission’s rules, to the 
extent practical, to the decisions that the international community made at WRC-07 and will collectively 
promote the advancement of new and expanded services and provide significant benefits to the American 
public.
B. Summary of Significant Issues Raised by Public Comments in Response to the 
IRFA
3. No comments were filed in direct response to the IRFA.
C. Response to Comments by the Chief Counsel for Advocacy of the Small Business 
Administration
4. Pursuant to the Small Business Jobs Act of 2010, the Commission is required to respond 
to any comments filed by the Chief Counsel for Advocacy of the Small Business Administration (SBA), 
and to provide a detailed statement of any change made to the proposed rules as a result of those 
comments.  The Chief Counsel did not file any comments in response to the proposed rules in this 
proceeding.
D. Description and Estimate of the Number of Small Entities to Which the Adopted 
Rules Will Apply
5. The RFA directs agencies to provide a description of and, where feasible, an estimate of 
the number of small entities that may be affected by the proposed rules, if adopted.
4
  The RFA generally 
defines the term “small entity” as having the same meaning as the terms “small business,” “small 
organization,” and “small governmental jurisdiction.” In addition, the term “small business” has the 
same meaning as the term “small business concern” under the Small Business Act.

See 5 U.S.C. § 603.  The RFA, see 5 U.S.C. § 601 – 612, has been amended by the Small Business Regulatory 
Enforcement Fairness Act of 1996 (SBREFA), Pub. L. No. 104-121, Title II, 110 Stat. 857 (1996), and the Small 
Business Jobs Act of 2010, Public Law No. 111-240, 124 Stat. 2504 (2010).

concern is one which: 1) is independently owned and operated; 2) is not dominant in its field of 
operation; and 3) satisfies any additional criteria established by the SBA.
6
Small Businesses, Small Organizations, and Small Governmental Jurisdictions. Our action may, 
over time, affect small entities that are not easily categorized at present. We therefore describe here, at 
the outset, three comprehensive, statutory small entity size standards.
7
First, nationwide, there are a total 
of 28.2 million small businesses, according to the SBA.
8
In addition, a “small organization” is generally 
“any not-for-profit enterprise which is independently owned and operated and is not dominant in its 
field.”
9
Nationwide, as of 2012, there were approximately 2,300,000 small organizations.
10
Finally, the 
term “small governmental jurisdiction” is defined generally as “governments of cities, towns, townships, 
villages, school districts, or special districts, with a population of less than fifty thousand.”
11
Census 
Bureau data for 2012 indicate that there were 90,056 local governments in the United States.
12
Thus, we 
estimate that most governmental jurisdictions are small.
Amateur Radio Service.  Because “small entities,” as defined in the RFA, are not persons eligible for 
licensing in the amateur service, this rule does not apply to “small entities.”  Rather, it applies exclusively 
to individuals who are the control operators of amateur radio stations.
Satellite Telecommunications and All Other Telecommunications.  Two economic census categories 
address the satellite industry.  Both these categories have a small business size standard of $32.5 million 
or less in annual receipts under SBA rules.
13
  
The category of Satellite Telecommunications “comprises establishments primarily engaged in providing 
telecommunications services to other establishments in the telecommunications and broadcasting 
industries by forwarding and receiving communications signals via a system of satellites or reselling 
satellite telecommunications.”
14
  Census Bureau data for 2007 show that 512 Satellite 
Telecommunications firms operated for that entire year.
15
  Of this total, 464 firms had annual receipts of 
under $10 million, and 18 firms had receipts of $10 million to $24,999,999.
16
  Consequently, the 
(Continued from previous page)                                                           
5
5 U.S.C. § 601(3) (incorporating by reference the definition of “small business concern” in 15 U.S.C. § 632). 
Pursuant to the RFA, the statutory definition of a small business applies “unless an agency, after consultation with the 
Office of Advocacy of the Small Business Administration and after opportunity for public comment, establishes one or 
more definitions of such term which are appropriate to the activities of the agency and publishes such definition(s) in 
the Federal Register.”  5 U.S.C. § 601(3).

Commission estimates that the majority of Satellite Telecommunications firms are small entities that 
might be affected by our action.
The second category, i.e. “All Other Telecommunications” comprises “establishments primarily engaged 
in providing specialized telecommunications services, such as satellite tracking, communications 
telemetry, and radar station operation.  This industry also includes establishments primarily engaged in 
providing satellite terminal stations and associated facilities connected with one or more terrestrial 
systems and capable of transmitting telecommunications to, and receiving telecommunications from, 
satellite systems.  Establishments providing Internet services or voice over Internet protocol (VoIP) 
services via client-supplied telecommunications connections are also included in this industry.”
17
  For this 
category, Census Bureau data for 2007 show that there were a total of 2,383 firms that operated for the 
entire year.
18
  Of this total, 2,347 firms had annual receipts of under $25 million and 12 firms had annual 
receipts of $25 million to $49, 999,999.
19
  Consequently, the Commission estimates that the majority of 
All Other Telecommunications firms are small entities.
Fixed Microwave Services.  Fixed microwave services include common carrier,
20
private operational-
fixed,
21
and broadcast auxiliary radio services.
22
  At present, there are approximately 22,015 common 
carrier fixed licensees and 61,670 private operational-fixed licensees and broadcast auxiliary radio 
licensees in the microwave services.  The Commission has not created a size standard for a small 
business specifically with respect to fixed microwave services.  For purposes of this analysis, the 
Commission uses the SBA small business size standard for the category Wireless Telecommunications 
Carriers (except Satellite), which is 1,500 or fewer employees.
23
  The Commission does not have data 
specifying the number of these licensees that have no more than 1,500 employees, and thus we are unable 
at this time to estimate with greater precision the number of fixed microwave service licensees that would 
qualify as small business concerns under the SBA’s small business size standard.  Consequently, the 
Commission estimates that there are 22,015 or fewer common carrier fixed licensees and 61,670 or fewer 
private operational-fixed licensees and broadcast auxiliary radio licensees in the microwave services that 
may be small and may be affected by the rules and policies proposed herein.  We note, however, that the 
common carrier microwave fixed licensee category includes some large entities.
Wireless Telecommunications Carriers (except satellite).  This industry comprises establishments 
engaged in operating and maintaining switching and transmission facilities to provide communications 
via the airwaves.  Establishments in this industry have spectrum licenses and provide services using that

20
See 47 C.F.R. §§ 101 et seq. for common carrier fixed microwave services (except Multipoint Distribution 
Service).
21
Persons eligible under Parts 80 and 90 of the Commission’s Rules can use Private Operational-Fixed Microwave 
services.  See 47 C.F.R. Parts 80 and 90.  Stations in this service are called operational-fixed to distinguish them 
from common carrier and public fixed stations.  Only the licensee may use the operational-fixed station and only for 
communications related to the licensee’s commercial, industrial, or safety operations.
22
Auxiliary Microwave Service is governed by Part 74 of Title 47 of the Commission’s Rules.  See 47 C.F.R. 
Part 74.  This service is available to licensees of broadcast stations and to broadcast and cable network entities.  
Broadcast auxiliary microwave stations are used for relaying broadcast television signals from the studio to the 
transmitter, or between two points such as a main studio and an auxiliary studio.  The service also includes mobile 
television pickups, which relay signals from a remote location back to the studio.

spectrum, such as cellular phone services, paging services, wireless Internet access, and wireless video 
services.
24
  The appropriate size standard under SBA rules is for the category Wireless 
Telecommunications Carriers.  The size standard for that category is that a business is small if it has 
1,500 or fewer employees.
25
  Under the present and prior categories, the SBA has deemed a wireless 
business to be small if it has 1,500 or fewer employees.
26
  For this category, census data for 2007 show 
that there were 11,163 firms that operated for the entire year.
27
  Of this total, 10,791 firms had 
employment of 999 or fewer employees and 372 had employment of 1,000 employees or more.
28
  Thus 
under this category and the associated small business size standard, the Commission estimates that the 
majority of wireless telecommunications carriers (except satellite) are small entities that may be affected 
by our proposed action.
29
Wireless Equipment Manufacturers.  This industry is comprised of businesses primarily engaged in 
manufacturing radio, television broadcast, and wireless communications equipment.  Examples of 
products made by these establishments are: transmitting and receiving antennas, cable television 
equipment, cordless phones, global positioning system (GPS) equipment, pagers, cellular phones, mobile 
communications equipment, and radio and television studio and broadcasting equipment.
30
  In this 
category, the SBA has deemed a business manufacturing radio and television broadcasting equipment, 
wireless telecommunications equipment, or both, to be small if it has fewer than 750 employees.
31
  For 
this category of manufacturing, Census data for 2007 show that there were 919 firms that operated that 
year.  Of those establishments, 531 had between 1 and 19 employees; 240 had between 20 and 99 
employees; and 148 had more than 100 employees.
32
  Since 771 establishments had fewer than 100 
employees, and since only 148 had more than 100 employees, the vast majority of manufacturers in this 
category would be considered small under applicable standards.
Frequency Coordinators.  Neither the Commission nor the SBA has developed a small business size 
standard specifically applicable to spectrum frequency coordinators.  Since 2007, the Census Bureau has 
placed wireless firms within the broad, economic census category of Wireless Telecommunications 
Carriers (except Satellite).
33
  Under this category, the SBA has deemed a wireless business to be small if 
it has 1,500 or fewer employees.
34
  Census data for 2007 show that there were 1,383 firms that operated

that year.  Of those, 1,368 had fewer than 100 employees, and 15 firms had more than 100 employees.
35
  
Thus, under this category and the associated small business standard, the majority of firms can be 
considered small.
E. Description of Projected Reporting, Recordkeeping and Other Compliance 
Requirements for Small Entities
6. The WRC-07 R&O did not establish any new reporting or recordkeeping requirements 
for small entities.  The WRC-07 R&O established “other” compliance requirements for manufacturers of 
equipment, applicants/licensees, and frequency coordinators.  Licensees are required to use equipment 
and operate licensed stations in a manner that complies with the Commission’s existing and newly 
adopted rules.  The compliance requirements established in the WRC-07 R&O are the same for small and 
large entities.
7. Manufacturers of aircraft stations transmitting telemetry in the 1435-1525 MHz, 
2345-2395 MHz, or 5091-5150 MHz band must meet the following emissions limitations and frequency 
stability requirements:
• Except for emergency locator transmitters (ELTs) and when using single sideband (R3E, H3E, J3E), 
or frequency modulation (F9) or digital modulation (F9Y) for telemetry or telecommand in the 
1435-1525 MHz, 2345-2395 MHz, or 5091-5150 MHz band or digital modulation (G7D) for 
differential GPS, the mean power of any emission must be attenuated below the mean power of the 
transmitter (pY) as follows: 1) When the frequency is removed from the assigned frequency by more 
than 50 percent up to and including 100 percent of the authorized bandwidth the attenuation must be 
at least 25 dB; 2) When the frequency is removed from the assigned frequency by more than 100 
percent up to and including 250 percent of the authorized bandwidth the attenuation must be at least 
35 dB; 3) When the frequency is removed from the assigned frequency by more than 250 percent of 
the authorized bandwidth the attenuation for aircraft station transmitters’ emissions must be at least 
40 dB; and the attenuation for aeronautical station transmitters’ emissions must be at least 
43 + 10 log10 pY dB.
• When using frequency modulation or digital modulation for telemetry or telecommand in the 
1435-1525 MHz, 2345-2395 MHz, or 5091-5150 MHz band with an authorized bandwidth equal to 
or less than 1 megahertz the emissions must be attenuated as follows: (1) On any frequency removed 
from the assigned frequency by more than 100 percent of the authorized bandwidth up to and 
including 100 percent plus 0.5 megahertz, the attenuation must be at least 60 dB, when measured in a 
3.0 kilohertz bandwidth. This signal need not be attenuated more than 25 dB below 1 milliwatt. (2) 
On any frequency removed from the assigned frequency by more than 100 percent of the authorized 
bandwidth plus 0.5 megahertz, the attenuation must be at least 55 + 10 log10 pY dB when measured 
in a 3.0 kilohertz bandwidth.
• When using frequency modulation or digital modulation for telemetry or telecommand in the 
1435-1525 MHz, 2345-2395 MHz, or 5091-5150 MHz band with an authorized bandwidth greater 
than 1 megahertz, the emissions must be attenuated as follows: 1) On any frequency removed from 
the assigned frequency by more than 50 percent of the authorized bandwidth plus 0.5 megahertz up to 
and including 50 percent of the authorized bandwidth plus 1.0 megahertz, the attenuation must be 
60 dB, when measured in a 3.0 kilohertz bandwidth. The signal need not be attenuated more than 
25 dB below 1 milliwatt. 2) On any frequency removed from the assigned frequency by more than 
50 percent of the authorized bandwidth plus 1.0 megahertz, the attenuation must be at least 
55 + 10 log10 pY dB, when measured in a 3.0 kilohertz bandwidth.

• The carrier frequency tolerance of all transmitters that operate in the 1435-1525 MHz or 
2345-2395 MHz band is 0.002 percent.  The carrier frequency tolerance of all transmitters that 
operate in the 5091-5150 MHz band is 0.005 percent.
8. In addition, manufacturers of equipment must meet the following requirements:
• The following unwanted emission power limits for non-geostationary satellites operating in the 
inter-satellite service that transmit in the 22.55-23.55 GHz band shall apply in any 200 megahertz of 
the 23.6-24 GHz passive band, based on the date that complete advance publication information is 
received by the ITU’s Radiocommunication Bureau: For information received before January 1, 
2020: -36 dBW/200 MHz. For information received on or after January 1, 2020: -46 dBW/200 MHz.
• For new fixed stations in the 31-31.3 GHz band authorized three years after the effective date of the 
WRC-07 R&O, the unwanted emission power in any 100 megahertz of the 31.3-31.5 GHz band shall 
be limited to -38 dBW (-38 dBW/100 MHz), as measured at the input to the antenna.
• For earth stations in the Fixed-Satellite Service (Earth-to-space) that transmit in the 49.7-50.2 GHz
and 50.4-50.9 GHz bands, the unwanted emission power in the 50.2-50.4 GHz band shall not 
exceed -20 dBW/200 MHz (measured at the input of the antenna), except that the maximum 
unwanted emission power may be increased to -10 dBW/200 MHz for earth stations having an 
antenna gain greater than or equal to 57 dBi.  These limits apply under clear-sky conditions.  During 
fading conditions, the limits may be exceeded by earth stations when using uplink power control.
9. The following requirements apply to applicants/licensees or frequency coordinators:
• In the 1435-1452 MHz band, operators of aeronautical telemetry stations are encouraged to take all 
reasonable steps to ensure that unwanted emissions power level does not exceed -28 dBW/27 MHz in 
the 1400-1427 MHz band.  Operators of aeronautical telemetry stations that do not meet this limit 
shall first attempt to operate in the 1452-1525 MHz band prior to operating in the 1435-1452 MHz
band.
• In the 1435-1525 MHz, 2345-2360 MHz (only until January 1, 2020), 2360-2395 MHz, and 
5091-5150 MHz bands, each application for a new station license, renewal or modification of an 
existing license concerning flight test frequencies, except as provided in paragraph (b) of 
Section 87.305, must be accompanied by a statement from a frequency advisory committee.  The 
committee must comment on the frequencies requested or the proposed changes in the authorized 
station and the probable interference to existing stations.  The committee must consider all stations 
operating on the frequencies requested or assigned within 320 km (200 mi) of the proposed area of 
operation and all prior coordinations and assignments on the proposed frequency(ies).  The 
committee must also recommend frequencies resulting in the minimum interference.  The committee 
must coordinate in writing all requests for frequencies or proposed operating changes in the 1435-
1525 MHz, 2345-2360 MHz (only until January 1, 2020), 2360-2395 MHz, and 5091-5150 MHz 
bands with the responsible Government Area Frequency Coordinators listed in the NTIA “Manual of 
Regulations and Procedures for Federal Radio Frequency Management.”  In addition, committee 
recommendations may include comments on other technical factors and may contain recommended 
restrictions which it believes should appear on the license.
• New fixed stations in the 10.6-10.68 GHz band are restricted to point-to-point operations, with each 
station supplying not more than -3 dBW of transmitter power to the antenna, producing not more than 
40 dBW of EIRP, and radiating at an antenna main beam elevation angle of 20° or less.
• Any application for a new station license to provide Multichannel Video Programming Distributors 
operations in the 17.7-17.8 GHz band or to operate in the 17.8-19.7 GHz band for any service, or for 
modification of an existing station license in these bands which would change the frequency, power, 
emission, modulation, polarization, antenna height or directivity, or location of such a station, be 
coordinated with the Federal Government by the Commission before an authorization will be issued, 
if the station or proposed station is located in whole or in part within any of the following areas:

(1) San Miguel, CA area: Between latitudes 34° 39' N and 34° 00' N and between longitudes 118° 52' 
W and 119° 24' W or within 200 km of 35° 44' N, 120° 45' W; and (2) Guam area: Within 100 km of 
13° 35' N, 144° 51' E.
F. Steps Taken to Minimize Significant Economic Impact on Small Entities and 
Significant Alternatives Considered
10. The RFA requires an agency to describe any significant alternatives that it has considered 
in reaching its proposed approach, which may include the following four alternatives (among others): 
1) the establishment of differing compliance or reporting requirements or timetables that take into 
account the resources available to small entities; 2) the clarification, consolidation, or simplification of 
compliance or reporting requirements under the rule for small entities; 3) the use of performance, rather 
than design, standards; and 4) an exemption from coverage of the rule, or any part thereof, for small 
entities.
36
11. In the WRC-07 NPRM, the Commission proposed to delete the non-Federal radiolocation 
service (RLS) allocation from the 1900-2000 kHz band, stating that a review of its licensing database 
found that no one is licensed to use this allocation.  In its reply comments to the WRC-07 NPRM, ITM 
Marine stated that the U.S.-based high seas migratory species fishing fleets operate radio buoys in the 
1900-2000 kHz band.  In order to remove the otherwise unused RLS allocation from the Allocation Table
without affecting existing radio buoy use by U.S. commercial fishing vessels, the WRC-07 R&O added a 
new footnote to the Allocation Table (footnote NG92) that authorizes U.S. commercial fishing vessels to 
continue to use radio buoys on the open sea under a ship station license.  This action is expected to have a 
positive non-burdensome impact on commercial fishing vessels, many of which are owned by small 
businesses, by authorizing these entities to operate radio buoys under a ship station license instead of 
obtaining separate licenses for the radio buoys.
12. The WRC-07 R&O delays the implementation of the unwanted emissions power limit for 
new fixed stations in the 31-31.3 GHz band.  Because the Commission has delayed the implementation of 
this new requirement for 3 years, it appears that the economic impact of this requirement has been 
minimized to the extent practicable for all licensees, including small entities.
Report to Congress: The Commission will send a copy of the Report and Order, including this FRFA, 
in a report to Congress pursuant to the Congressional Review Act.
37
  In addition, the Commission will 
send a copy of the Report and Order, including this FRFA, to the Chief Counsel for Advocacy of the 
SBA.  A copy of the Report and Order and FRFA (or summaries thereof) will also be published in the 
Federal Register.

APPENDIX G
Initial Regulatory Flexibility Analysis
1. As required by the Regulatory Flexibility Act (RFA),
1
the Commission has prepared this 
present Initial Regulatory Flexibility Analysis (IRFA) of the possible significant economic impact on 
small entities by the policies and rules proposed in this WRC-12 Notice of Proposed Rule Making 
(WRC-12 Notice).  Written public comments are requested on this IRFA.  Comments must be identified 
as responses to the IRFA and must be filed by the deadlines for comments provided on the first page of 
this WRC-12 Notice.  The Commission will send a copy of this WRC-12 Notice, including this IRFA, to 
the Chief Counsel for Advocacy of the Small Business Administration (SBA).
2
  In addition, the WRC-12 
Notice and IRFA (or summaries thereof) will be published in the Federal Register.
3
A. Need for, and Objectives of, the Proposed Rules
2. In the WRC-12 Notice, the Commission proposes to amend parts 2, 15, 80, 90, 97, and 
101 of its rules to implement certain of the allocation decisions from the World Radiocommunication 
Conference (Geneva, 2012) (WRC-12) in the Commission’s Table of Frequency Allocations, and to make 
certain updates to its service rules.  If adopted, these proposals would conform the Commission’s rules, to 
the extent practical, to the decisions that the international community made at WRC-12 and would 
promote the advancement of new and expanded services and provide significant benefits to the American 
public.
B. Legal Basis
3. The proposed action is authorized under Sections 4(i), 301, 303(c), 303(f), and 303(r) of 
the Communications Act of 1934, as amended, 47 U.S.C. §§ 154(i), 301, 303(c), 303(f), and 303(r).
C. Description and Estimate of the Number of Small Entities To Which the Proposed 
Rules Will Apply
4. The RFA directs agencies to provide a description of and, where feasible, an estimate of 
the number of small entities that may be affected by the proposed rules, if adopted.
4
The RFA generally 
defines the term “small entity” as having the same meaning as the terms “small business,” “small 
organization,” and “small governmental jurisdiction."
5
  In addition, the term “small business” has the 
same meaning as the term “small business concern” under the Small Business Act.

  A small business 
concern is one which:  (1) is independently owned and operated; (2) is not dominant in its field of 
operation; and (3) satisfies any additional criteria established by the SBA.

Small Businesses, Small Organizations, and Small Governmental Jurisdictions. Our action may, 
over time, affect small entities that are not easily categorized at present. We therefore describe here, at

See 5 U.S.C. § 603.  The RFA, see 5 U.S.C. § 601 – 612, has been amended by the Small Business Regulatory 
Enforcement Fairness Act of 1996 (SBREFA), Pub. L. No. 104-121, Title II, 110 Stat. 857 (1996).

5 U.S.C. § 601(3) (incorporating by reference the definition of “small business concern” in 15 U.S.C. § 632). Pursuant 
to the RFA, the statutory definition of a small business applies “unless an agency, after consultation with the Office of 
Advocacy of the Small Business Administration and after opportunity for public comment, establishes one or more
definitions of such term which are appropriate to the activities of the agency and publishes such definition(s) in the 
Federal Register.”  5 U.S.C. § 601(3).

the outset, three comprehensive, statutory small entity size standards.
8
First, nationwide, there are a total 
of 28.2 million small businesses, according to the SBA.
9
In addition, a “small organization” is generally 
“any not-for-profit enterprise which is independently owned and operated and is not dominant in its 
field.”
10
Nationwide, as of 2012, there were approximately 2,300,000 small organizations.
11
Finally, the 
term “small governmental jurisdiction” is defined generally as “governments of cities, towns, townships, 
villages, school districts, or special districts, with a population of less than fifty thousand.”
12
Census 
Bureau data for 2012 indicate that there were 90,056 local governments in the United States.
13
Thus, we 
estimate that most governmental jurisdictions are small.
Amateur Radio Service.  Because “small entities,” as defined in the RFA, are not persons eligible for 
licensing in the amateur service, this proposed rule does not apply to “small entities.”  Rather, it applies 
exclusively to individuals who are the control operators of amateur radio stations.
Wireless Telecommunications Carriers (except satellite).  This industry comprises establishments 
engaged in operating and maintaining switching and transmission facilities to provide communications 
via the airwaves.  Establishments in this industry have spectrum licenses and provide services using that 
spectrum, such as cellular phone services, paging services, wireless Internet access, and wireless video 
services.
14
  The appropriate size standard under SBA rules is for the category Wireless 
Telecommunications Carriers.  The size standard for that category is that a business is small if it has 1,500 
or fewer employees.
15
  Under the present and prior categories, the SBA has deemed a wireless business to 
be small if it has 1,500 or fewer employees.
16
  For this category, census data for 2007 show that there 
were 11,163 firms that operated for the entire year.
17
  Of this total, 10,791 firms had employment of 999 
or fewer employees and 372 had employment of 1,000 employees or more.
18
  Thus under this category 
and the associated small business size standard, the Commission estimates that the majority of wireless 
telecommunications carriers (except satellite) are small entities that may be affected by our proposed 
action.

D. Description of Projected Reporting, Recordkeeping, and Other Compliance 
Requirements for Small Entities
5. The WRC-12 Notice does not propose to establish any new reporting or recordkeeping 
requirements for small entities.  The WRC-12 Notice proposes to establish “other” compliance 
requirement for applicants/licensees.  The compliance requirements proposed in the WRC-12 Notice are 
the same for small and large entities.
6. The WRC-12 Notice proposes that frequencies in the 1900-2000 kHz band be authorized 
for radio buoy operations under a ship station license provided: 1) The use of these frequencies is related 
to commercial fishing operations on the open sea.  This use is not permitted within the exclusive 
economic area or territorial waters of a foreign country (unless provided for by an international 
agreement); and 2) The output power does not exceed 10 watts and the station antenna height does not 
exceed 4.6 meters (15 feet) above sea level in a buoy station or 6 meters (20 feet) above the mast of the 
ship on which it is installed.
7. The WRC-12 Notice proposes to limit radiolocations service operations in the 
4438-4488 kHz, 5250-5275 kHz, 13.45-13.55 GHz, 16.10-16.20 MHz, 24.45-24.65 MHz, 
26.20-26.42 MHz, 41.015-41.665 MHz, 43.35-44 MHz to oceanographic radars using transmitters with a 
peak equivalent isotropically radiated power that do not exceed 25 dBW. The WRC-12 Notice also 
proposes that oceanographic radars must not cause harmful interference to, nor claim protection from 
interference caused by, stations in the incumbent fixed or mobile services.  In addition, the proposed rules 
provide a cross reference to Resolution 612 of the ITU Radio Regulations for the international 
coordination requirements.  These requirements state that each oceanographic radar station shall transmit 
a station identification (call sign) on the assigned frequency, in international Morse code at manual speed, 
at the end of each data acquisition cycle, but at an interval of no more than 20 minutes; and that the 
separation distances between an oceanographic radar and the border of other countries shall be between 
80 and 920 kilometers.  Finally, the WRC-12 Notice proposes to require that licensees of oceanographic 
radars that currently operate under Part 5 of the rules transition their operations to frequencies within an 
allocated band within 5 years of the adoption of final rules in this proceeding.
E. Steps Taken to Minimize Significant Economic Impact on Small Entities, and 
Significant Alternatives Considered
8. The RFA requires an agency to describe any significant alternatives that it has considered 
in reaching its proposed approach, which may include the following four alternatives (among others): 
(1) the establishment of differing compliance or reporting requirements or timetables that take into 
account the resources available to small entities; (2) the clarification, consolidation, or simplification of 
compliance or reporting requirements under the rule for small entities; (3) the use of performance, rather 
than design, standards; and (4) an exemption from coverage of the rule, or any part thereof, for small 
entities.

9. The WRC-12 Notice proposes to authorize commercial fishing vessels to operate radio 
buoys in the 1900-2000 kHz band under a ship station license.  This action is expected to have a positive 
non-burdensome impact on commercial fishing vessels, many of which are owned by small businesses, 
by authorizing these entities to operate radio buoys under a ship station license instead of obtaining 
separate licenses for the radio buoys.

10. The WRC-12 Notice proposes that the 156.7625-156.7875 MHz and 
156.8125-156.8375 MHz bands may continue to be used by non-Federal ship and coast stations for 
navigation-related port operations or ship movement until August 26, 2019.  Because of the proposed 
delayed transition date, we believe that we have minimized the impact on a small business that operates 
coast stations in these bands to extent practicable.
F. Federal Rules that May Duplicate, Overlap, or Conflict With the Proposed Rule
11. None.
