DRAFT PROPOSALS FOR THE WORK OF THE CONFERENCE
Agenda Item 1.3: To consider spectrum requirements and possible regulatory actions, including
allocations, in order to support the safe operation ofunmanned aircraft systems (VAS), based on
the results ofITV-R studies, in accordance with Resolution 421 (WRC-07)
Background Information: Unmanned aircraft systems (UASs) enable the remote piloting of
aircraft over short range and significant distances within or out-of-sight of the remote pilot.
These flight operations currently take place in segregated airspace, to ensure the safety of the air
vehicle and other airspace users.
Some administrations expect deployment of UASs throughout the airspace structure. As UAS
deployment increases, it will be impractical for some users to deploy in segregated airspace.
Some UASs will need to integrate with the current airspace users in a safe and seamless manner.
To accomplish integration into non-segregated airspace, UASs will require high integrity
communication links between the unmanned aircraft (UA) and remote control centers capable of
relaying the necessary air traffic control (ATC) messages and flight critical aircraft information.
The UAS pilot will need sense and avoid functions for situational awareness.
The International Civil Aviation Organization (ICAO) future communications study may be able
to identify technologies with some capability to meet the requirements for command and control,
including the relaying of ATC communications. The aeronautical mobile (R) service (AM(R)S)
and aeronautical mobile-satellite (R) service (AMS(R)S) are the appropriate services to
accommodate command and control and ATC radiocommunications. The ITU-R is examining
existing aeronautical allocations to satisfy spectrum requirements prior to studying new
allocations.
Command & Control
In non-segregated airspace, the remote pilot must reliably monitor the status of the UA,
pass control instructions to their UA, and interact with the appropriate air traffic
controllers monitoring airspace within which their UA is flying. A line-of-sight link
might provide these capabilities for UA flying and maneuvering in a localized area. A
combination of a terrestrial radio and satellite network could provide these capabilities to
UA flying trans-horizon.
Relay ofAir Traffic Control (ATC) Communications
Safe operation of manned or unmanned aircraft depends on ATC communications. Pilots
act based on ATC instructions. When the pilot is remote (not in the aircraft) the pilot and
ATC must maintain a communication channel to relay information from a radio in the
aircraft to the pilot on the ground. Early concepts assume that this function, if digitized,
could be part of the command and control links.
Sense and Avoid
The safe flight operation of UA necessitates advanced techniques to detect and track
nearby aircraft, terrain, and obstacles to navigation. Unmanned aircraft must avoid these
objects in a manner equivalent to that of a manned aircraft. The remote pilot will need to
3
be aware of the environment within which the aircraft is operating, be able to identify the
potential threats to the continued safe operation of the aircraft, and take the appropriate
action. The radiodetermination service allocations could potentially accommodate the
sense and avoid function. The ITU-R is examining existing aeronautical radionavigation
service (ARNS) allocations for suitable bandwidth prior to studying new ARNS
allocations. The UAS industry is studying the suitability of various technologies for
sense and avoid.
Payload
Resolution 421 (WRC-07) Resolves 1 specifically excludes the allocation of spectrum at
WRC-ll for payload applications. However, invites ITU-R 3 does call for the
development of an ITU-R report or recommendation on how to accommodate the
radiocommunication requirements for UAS payloads. The purpose of this agenda item is
not to seek new spectrum allocations to meet payload requirements.
This agenda item seeks to identify the spectrum requirements necessary to support the safe
operation of UASs in current and future airspace structures. Spectrum for UAS for safety and
regularity of flight in non-segregated airspace can be accommodated in ""'ill need AM(R)S,
AMS(R)S, or ARNS allocations or in other allocations that can meet performance requirements
established by ICAO/ITU-R Recommendation. in order to receive the sufficient status and
protection from harmful interference.
The 5030-5091 MHz band is an appropriate band to satisfy the terrestrial, line-of-sight,
spectrum requirements for the command and control of UASs in non-segregated airspace.
Currently, there is minimum usage in this band worldwide. The lack of an existing or planned
microwave landing system deployment in the United States ensures availability of appropriate
aeronautical spectrum for a terrestrialline-of-sight UAS system in the 5030-5091 MHz band.

PROPOSAL FOR THE WORK OF THE CONFERENCE
Agenda Item 1.5: To consider worldwide/regional harmonization of spectrum for
electronic news gathering (ENG), taking into account the results of ITU-R studies in
accordance with Resolution 954 (WRC-07);
Background:
WRC-07 established Resolution 954 (WRC-07), which 'invites ITU-R to carry out
studies of ENG regarding possible solutions for global/regional harmonization in
frequency bands and tuning ranges, taking into account: available technologies to
maximize efficient and flexible use of frequency; system characteristics and operational
practices which facilitate the implementation of these solutions... ' CPM11-1 established
a framework for the studies to be undertaken as outlined in Resolution 954 (WRC-07)
under WRC-11 Agenda Item 1.5.
Resolution 954 calls for the ITU-R to include in its studies "...sharing and compatibility
issues with services already having allocations in frequency bands and tuning ranges
which have potential for ENG use" and "to propose operational measures to facilitate
operation of ENG equipment consistent with global circulation of radiocommunication
equipment.." Furthermore the ITU-R is to "...report the results of those studies to the
World Radiocommunication Conference 2011".
There is no specific mention of addressing changes to the Article 5 of the Radio
Regulations in either the agenda item text or in Res 954. Thus careful consideration
needs to be given to any solutions for this agenda item that refer to regulatory changes in
Article 5. It may be possible that rationalization (the use of available technology to
maximize efficient and flexible use of frequency assets) would be effective in utilizing
existing spectrum allocations in the mobile and fixed service where ENG is employed
Recommendation ITU-R M.1824, "System characteristics of television outside
broadcast, electronic news gathering and electronic field production in the mobile
service for use in sharing studies ", provides digital and analogue system parameters for
BAS in the mobile service. Recommendation ITU-R F.1777, "System characteristics of
television outside broadcast, electronic news gathering and electronic field production in
the fixed service for use in sharing studies ", provides digital and analogue system
parameters for BAS in the fixed service. Report ITU-R BT.2069, "Spectrum usage and
operational characteristics of terrestrial electronic news gathering systems (ENG),
7
Television Outside Broadcast (TVOB) and Electronic Field Production (EFP)", provides
specifications for BAS.
Spectrum harmonization provides many benefits but may not be feasible given the
disparate use of spectrum by countries around the world and the differing broadcasting
standards used in the three ITU Regions. Instead a mechanism for spectrum
rationalization may be more productive in allowing broadcasters to gain knowledge of,
and access to, the spectrum used to support ENG operations in a given country or Region.
This will help to ensure that international news-worthy events can be covered with a
minimum of disruption to both foreign broadcasters and domestic regulators alike. The
harmonization, or rather rationalization, of spectrum for ENG use should be considered
on a band-by-band basis for each of the separate applications described in Report ITU-R
BT. 2069-2. Furthermore it is recognized that the transition from analog to digital
broadcasting will impact how ENG operations are conducted.

DRAFT RESOLUTION [USA-1.511] (WRC-U)
Spectrum Management Guidelines for Electronic News Gathedng (ENG)!
The World Radiocommunication Conference (Geneva, 2011),
considering
a) that some administrations may have different operational needs and spectrum
requirements for electronic news gathering;
b) that the dynamic nature of the use of ENG, which is driven by scheduled,
unscheduled and unpredictable events such as breaking news, emergencies and
disasters makes it highly desirable to facilitate the rapid and less restricted
deployment and operation of ENG systems from one country to another,
recognizing
a) that broadcasting ancillary services can be utilized as part of an administration's
telecommunications/information and communication technologies (ICTs) systems
in service of management in emergency and disaster situations for early warning,
prevention, mitigation, and relief;
b) that Recommendation ITU-R M.1824 provides system characteristics of
television outside broadcast, electronic news gathering (ENG) and electronic field
production (EFP) in the mobile service for use in sharing studies;
8
c) that Recommendation ITU-R F.1777 provides system characteristics of television
outside broadcast, electronic news gathering and electronic field production in the
fixed service for use in sharing studies;
d) that a large number of bands in Mobile and Fixed spectrum are already used to
host various elements of electronic news gathering applications;
e) that Report ITU-R BT.2069 provides spectrum usage and operational
characteristics of terrestrial ENG, television outside broadcast (TVOB) and EFP
systems,
noting
a) that when an international news worthy event happens, ENG operations must be
deployed in a very short time-frame;
b) that frequency coordination must be undertaken with the Administration where
an international news-worthy event takes place;
c) that advance information on the frequencies available for ENG use in any given
Administration may ease interoperability and/or internetworking , especially in
international news-worthy events that draw broadcasters regionally or globally,
noting further
a) that it is in the interest of administrations and broadcasters to have access to
updated information on national spectrum planning for ENG use,
resolves
1 to encourage administrations to assist the broadcasting community in developing
a database of currently available ENG frequencies, ENG technical and operational
requirements, and spectrum authorization points of contact as appropriate,
instructs the Director ofthe Radiocommunication Bureau
1) to maintain a link on the ITU-R website to the broadcast community's database(s)
referenced in the resolves above;
2) to report on the progress on this Resolution to subsequent World
Radiocommunication Conferences,
urges administrations
1) to provide the broadcasting community with the relevant information concerning
their national ENG frequency allocations, ENG spectrum management practices,
and appropriate points-of-contact for ENG usage within their administration;
2) to assist the broadcasting community in keeping the ENG database current.
Reason: It is important that information be provided and maintained on ENG usage
around the world. Resolution USA-1.5/1 provides a mechanism to rationalize ENG
spectrum usage by maintaining a data-base of country specific ENG bands with required
technical and operational requirements for deployment. This will provide ENG users and
operators with the needed information to ensure that they deploy equipment that will
operate within a given country and allow them to seek spectrum use approval in an
expeditious manner. It will also provide manufacturers with a knowledge base of
9
required frequency bands and deployment requirements needed to build common-use
equipment for the worldwide ENG market.

DRAFT PROPOSAL FOR THE WORK OF THE CONFERENCE
Agenda item 1.17: to consider results of sharing studies between the mobile service and
other services in the band 790-862 MHz in Regions 1 and 3, in accordance with Resolution 749
(WRC-07), to ensure the adequate protection of services to which this frequency band is
allocated, and take appropriate action;
Background:
The transition to digital television is underway in many countries worldwide. The eventual
global transition to digital television will make spectrum available for introduction of the new
services, including next generation wireless services. The WRC-ll decisions under the Agenda
Item 1.17 are therefore, important to operators, manufacturers and, most importantly, consumers
worldwide.
At WRC-07, there were difficult discussions surrounding the future use of the 790-862 MHz band
in Region 1 and in the end FN 5.316B was agreed allocating 790-862 MHz to the Mobile service,
except aeronautical, on a primary basis starting from 17 June 2015, the DTV transition date in the
GE06 Agreement. The footnote also states that the use of stations of the mobile service is subject
to the successful application of the procedures of the GE06 Agreement for those countries party
to it. FN 5.316 was updated and FN 5.316A was developed, allocating 790-862 MHz to the
Mobile service in 65 Region 1 countries effective immediately and in force until 16 June 2015.
FN 5.317A identifies for IMT those parts of the band 790-960 MHz in Region 1 which are
allocated to the Mobile service on a primary basis.
Due to the extensive debates in Region 1 concerning this band, Resolution 749 (WRC-07):
Studies on the use of the band 790-862 MHz by mobile applications and by other services, was
developed.
The GE06 Agreement contains a plan for digital TV covering frequencies including the 790-862
MHz band in Region l(parts of Region 1 situated to the west of meridian 170° east and nOlth of
parallel 40° south, except the territory of Mongolia) and one country in Region 3 The GE06
Agreement also contains regulatory provisions concerning sharing between the terrestrial
broadcasting service and other terrestrial services, as well as the list of other primary terrestrial
services. The GE06 Agreement appears to provide sufficient regulatory framework to address
sharing issue between the mobile service and other services in the band 790-862 MHz between
countries that are signatories to this agreement.
With regard to Region 3, it is important to recognize that allocation to the mobile service in the
band 790-862 MHz has been in effect since WARC-71. If there have been no reported instances
of interference, then this should be taken into account when considering any regulatory changes.
11
With regard to Region 2, WRC-07 allocated the band 698-806 MHz to the mobile service on a
co-primary basis and identified it for use by IMT systems. Some Region 2 administrations have
successfully completed the realignment of allocations in this spectrum while others are
progressing towards that goal. In addition, WRC-07 determined that there is no need to conduct a
further review of the regulatory provisions concerning the use of the band 790-862 MHz in
Region 2. That decision is explicitly affirmed in the Agenda Item 1.17 and the associated
Resolution 749 (WRC-07).

Reasons: WRC-12 Agenda Item 1.17 is limited to terrestrial services only in Regions I and 3
and only in the band 790-862 MHz. There are no bases for any changes in the Radio Regulations
that would impact the terrestrial services in the band 790-862 MHz in Region 2. Therefore, the
13
United States proposes NOC with respect to any change to Article 5 that could impact Region 2
services in the band 790-862 MHz. The worldwide introduction of new telecommunications
services in the mobile and fixed service allocations in this band requires stable allocations that are
harmonized to the greatest degree possible.

DRAFT PROPOSALS FOR THE WORK OF THE CONFERENCE
WRC·12 Agenda Item 1.19: to consider regulatory measures and their relevance, in
order to enable the introduction ofsoftware-defined radio and cognitive radio systems,
based on the results ofITU-R studies, in accordance with Resolution 956 (WRC·07).
BACKGROUND: Resolution 956 (WRC-07) resolves to invite ITU-R to study whether there is
a need for regulatory measures to enable the introduction of software-defined radio and cognitive
radio systems.
Software defined radios (SDR) and cognitive radio systems (CRS) are technologies which may
offer improved efficiency to the overall spectrum use and provide additional flexibilities to
radiocommunication services. They are not radiocommunication services themselves, but rather
are technologies that may be deployed in radiocommunication systems.
Any system that incorporates SDR, CRS or combined SDRICRS technologies shall operate in
accordance with the provisions of the Radio Regulations and administration rules governing the
use of the frequency band in which the systems are intended to operate. To date, some
administrations have allowed such systems to operate on a licence-exempt, non-harmful
interference basis. In the U.S., the regulatory body has provided through equipment authorization
requirements operating parameters for SDRICRS devices to ensure that such devices will not
cause harmful interference to allocated radiocommunication services.
Relevant ITU-R working parties are conducting technical studies, as noted in Resolution 956
(WRC-07). The United States will participate as appropriate in these studies. The United States
does not believe that changes to the Radio Regulations are needed to address these technologies.
In particular, the United States does not support regulatory measures leading to allocations,
including identification footnotes, for software-defined radio and cognitive radio systems, as
these are technologies, each with its own attributes, and not radiocommunication services. With
respect to the definitions, description, or characterization of SDR or CRS, there is no need to
include a definition of SDR or CRS in the Radio Regulations.
PROPOSALS:
NOC USA/AI 1.19/1
ARTICLE 1
Terms and definitions
Reason: No changes to the Radio Regulations are necessary to enable the introduction of SDR
and CRS technologies. SDR and CRS techniques can be used with a range of technologies, and
in a range of frequency bands subject to appropriate equipment authorization procedures to
ensure that authorized devices operate within the limitations an administration applies to the
frequency bands in which these systems are permitted to operate. Any definitions developed for
SDR and CRS could be captured in an ITU-R Recommendation.

WRC-12 Agenda Item 1.22: to examine the effect ofemissions from short-range
devices on radiocommunication services, in accordance with Resolution 953 (WRC-07).
BACKGROUND: Resolution 953 (WRC-07) requests the ITU-R to study emissions from SRDs,
in particular RFIDs, inside and outside the frequency bands designated in the Radio Regulations
for ISM applications to ensure adequate protection of radiocommunication services.
The United States, like many other administrations, has adopted a flexible regulatory regime,
primarily in the ISM bands, that sets basic technical requirements that facilitate spectrum sharing
among license-exempt devices, including short-range devices, while minimizing constraints on
product designs. The technical requirements placed on these devices ensure adequate protection
of radiocommunication services operating in the same or adjacent frequency bands. This regime
has led to the implementation of a variety of devices, including cordless telephones, wireless
access systems, RFIDs, alarm systems and baby monitors.
Short-range devices have been studied by the ITU-R and the results are contained in
Recommendation ITU-R SM.1538-2. This Recommendation provides descriptions of short
range device applications, common frequency ranges and regulatory regimes adopted by several
Administrations.
The United States believes that the regulation of short-range devices is primarily a national matter
and that there is no need for any modifications to the international Radio Regulations to
accommodate these devices.

DRAFT PROPOSALS FOR THE WORK OF THE CONFERENCE
(Editorial notes: Redline in Background section is against the NTIA draft proposal.
Redline in the Proposal section is against the 2008 Edition of the Radio Regulations and is
offered as a substitute for the NTIA Proposal section.)
Agenda Item 1.23: to consider an allocation ofabout 15 kHz in parts ofthe band 415-526.5 kHz
to the amateur service on a secondary basis, taking into account the need to protect existing
services
Background Information: The spectrum between 415-526.5 kHz is currently allocated to
the maritime mobile and aeronautical radiolocation services, with some variances in the
allocations among the three ITU Regions.The maritime mobile service is a primary user of the
frequency band under cOflsideration for this agenda item. Footnote No. 5.82A advises, "The use
of the band 495-505 kHz is limited to radiotelegraphy." Footnote No. 5.82B advises,
"Administrations authorizing the use of frequencies in the band 495-505 kHz by services other
than the maritime mobile service shall ensure that no harmful interference is caused to the
maritime mobile service in this band or to the services having allocations in the adjacent bands,
noting in particular the conditions of use of the frequencies 490 kHz and 518 kHz, as prescribed
in Articles 31 and 52." NAVTEX services operate on 490 kHz and 518 kHz per Resolution 339
(Rev. WRC-07). There is a common primary mobile service allocation across all three
Regions in the band 495-505 kHz. In Region 2, the primary mobile service allocation
extends to 510kHz.
The band 495 505 I(Hz provides international harmonization and necessary maritime propagatiofl
characteristics for global harmoflizatiofl of maritime services.
The maritime community also has emerging requirements for globally harmonized interoperable
maritime spectrum in support of safety and security requirements ifl 415 526.5 kHz.The band
495-505 kHz was previously designated for mobile service distress and calling. The
frequency of 500 kHz was designated as an international calling and distress frequency.
Over the past two decades, safety and security operations near 500 kHz have been
replaced through the operation of the Global Maritime Distress Safety System. As a
result, designation of 500 kHz as an international distress and calling frequency was
suppressed at WRC-2000, and the broader designation of 495-505 kHz as a distress and
calling band was suppressed at WRC-07.
Maritime ship-to-ship and ship-to-shore telegraphy near 500 kHz has diminished, but is
still utilized on occasion by maritime mobile licensees and, in the United States, Coast
Guard Auxiliary operators.
Worldwide, the amateur service successfully shares spectrum as a secondary user to the
fixed service between 10.100 and 10.150 MHz. In some countries around the world,
including the United States, amateurs utilize specific channels between 5.25 and 5.45
18
MHz as secondary users to the fixed and mobile services. The primary interference
avoidance technique on these bands has been a listen-before-transmit protocol,
supplemented by appropriate regulatory power limitations. These techniques have led to
successful sharing arrangements, which should be replicable at or near 500 kHz.

DRAFT PROPOSAL FOR THE WORK OF THE CONFERENCE
WRC-11 Agenda Item: 1.13 to consider the results ofITU-R studies in accordance with
Resolution 55l (WRC-07) and decide on the spectrum usage ofthe 21.4-22 GHz bandfor the
broadcasting-satellite service and the associatedfeeder-link bands in Regions 1 and 3;
Background information:
In the U.S., the 23 GHz band is widely used in urban areas for many applications. The primary
ones are for backhauling wireless telephone traffic and for carrying business data and
communications in corporate networks. The propagation characteristics at 23 GHz make it
particularly suitable for wireless backhaul over relatively short distances. These links provide
connectivity between mobile cell towers and the central network facilities of the local carrier.
The growing sophistication of end-user wireless devices and services, from cell phones to
advanced wireless services and from voice to music and to real-time video, contributes to
increases in demand for backhaul capacity. At the same time, as wireless providers continue
subdividing their cells to extract maximum usage from costly spectrum, the number of towers
requiring backhaul increases in proportion. The band provides a vital resource for meeting this
need. As of June 2007, there were more than 4500 assignments in the sub-band 21.4-22 GHz in
the U.S. alone. There are numerous deployments in this frequency band in other Region 2
countries as well. It is therefore imperative to ensure that WRC-ll adopt regulatory solution(s)
that preserve the basic principle of equality to spectrum access in all Regions consistent with No.
4.8.
WARC-92 allocated the BSS in Regions I and 3 in the 21.4-22 GHz band with 1 April
2007 as the date of entry into force of the allocation. It also adopted Resolution 525 which
provided interim procedures for the introduction, before and after 1 April 2007, of high definition
television systems (HDTV) of the broadcasting-satellite service (BSS) in the band 21.4-22.0 GHz
in Regions 1 and 3 on a first-come-first-served basis. Resolution 525 has been revised several
times since 1992. Prior to 1 April 2007, in Regions 1 and 3, an interim coordination procedure
applied to operational BSS (HDTV) systems in the band 21.4 - 22.0 GHz for the protection of
terrestrial services operating in the same band based on pfd coordination thresholds. WRC-07
modified Resolution 525 by removing protection of terrestrial networks and removing the
procedures of No. 9.11. However, since Resolution 525 is applied by footnote 5.530, which
appears to the right of the broadcasting-satellite service allocations in Regions 1 and 3, the
Resolution 525 (Rev. WRC-07) provisions do not apply to any service in Region 2. (See No.
5.50 and 5.51). Thus, the procedures for the protection of terrestrial services in Region 2 from
the BSS in Regions 1 and 3 are not addressed in Resolution 525.
With regard to Region 2, the coordination requirements for the BSS systems that were
introduced in the 21.4-22 GHz band prior to 1 April 2007 are explicitly clear. Inter-Regional
22
protection of the FS was provided by Resolution 33 (Rev. WRC-03) which included a
coordination procedure applicable in all frequency bands allocated to the BSS. The WRC-03
version of Resolution 525 (Rev. WRC-03) was consistent with Resolution 33 (Rev. WRC-03) in
that these systems are subject to No. 9.11 coordination procedures. Resolution 525 (Rev. WRC 
03) required coordination if the power flux-density at the Earth's surface produced by emissions
from a space station, on the territory of any other country, exceeded:
-115 dB(W/m
2
) in any 1 MHz band for angles of arrival between 0
0
and 50 above
the horizontal plane; or
-105 dB(W/m
2
) in any 1 MHz band for angles of arrival between 25
0
and 90
0
above the horizontal plane; or
values to be derived by linear interpolation between these limits for angles of arrival
between 50 and 25
0
above the horizontal plane.
These threshold values for triggering coordination with terrestrial services are consistent
with reference power flux density for the BSS values that have been developed and given in
Recommendation ITU-R BO.1776. They are also consistent with the power flux-density limits
recommended for this band in Recommendation ITU-R F.760. It is important to recognize that
the ITU-R BO.1776 is referenced in Resolutions 525 (Rev. WRC-07) and 551 (Rev. WRC-07).
The coordination requirements for the BSS systems in the 21.4-22.0 GHz band
introduced after 1 April 2007 in respect to terrestrial services of Region 2 are conflicting and
ambiguous. Resolution 525 (Rev. WRC-07), as discussed previously, only applies to Regions 1
and 3 while Resolution 33 (Rev. WRC -03) applies for inter-Regional coordination, but it has no
pfd criterion for triggering coordination.
Considering the ambiguity associated with the implementation of the BSS allocation and
the difficulty of coordinating space stations with terrestrial stations, the U.S. notes that sharing
between satellite services in Regions 1 and 3 and terrestrial services in Region 2 can be most
simply implemented through a pfd limits regime in Article 21, Section V. In the present case, the
pfd values developed and given in Recommendation ITU-R BO.1776 and also applied to the BSS
systems that were introduced in the subject band prior to 1 April 2007 could be used as a power
flux-density limit that would apply to all BSS systems in region 1 and 3 for purposes of sharing
with the Fixed and Mobile services in Region 2. Such a limit would only apply to BSS satellite
networks' beams on the territories of Region 2 countries.

These limits shall apply only on territories of Region 2 countries.
Reasons: Sharing between satellite services in Regions 1 and 3 and terrestrial services in Region
2 can be implemented most simply through power flux density (pfd) limits specified in Article 21,
Section V. The proposed pfd values are consistent with Recommendation ITU-R BO.I776. It is
24
important to recognize that ITU-R BO.1776 is referenced in Resolutions 525 (Rev. WRC-07) and
551 (Rev. WRC-07). It is also important to recognize that these same pfd values are applied to
the BSS systems that were introduced in the 21.4-22.0 GHz band prior to 1 April 2007. The
proposed modification would provide regulatory certainty to satellite services as a defined set of
pfd limits would be known and extensive coordination with uncertain outcome would not be
required. The proposed modification would also reduce the administrative burden for
administrations in all Regions.

DRAFT PROPOSALS FOR THE WORK OF THE CONFERENCE
Agenda Item 1.7: to consider the results of[TU-R studies in accordance with Resolution 222
(Rev. WRC-07) in order to ensure long-term spectrum availability and access to spectrum necessary to
meet requirements for the aeronautical mobile-satellite (R) service, and to take appropriate action on this
subject, while retaining unchanged the generic allocation to the mobile-satellite service in the bands
1 525-1 559 MHz and 1 626.5-[ 660.5 MHz.
Background
The mobile satellite service allocations in 1525- 1559 MHz and 1626.5 - 1660.5 MHz continue to support
valuable communications requirements and are needed to address the future communications requirements
for commercial MSS as well as Global Maritime Distress and Safety System and aeronautical mobile
satellite service (R) service (AMS(R)S) requirements.
The MSS allocations with associated footnote provisions, providing priority and preemptive access to the
MSS systems for communications to support AMS(R)S, have allowed sufficient flexibility to satisfy the
AMS(R)S communications requirements in this band. There is no need to modify the MSS allocations
and the associated footnote regulatory provisions for AMS(R)S.
The USA proposes No Change (NOC) to the Table of Allocations for the MSS allocations in the 1525 
1559 MHz and 1626.5- 1660.5 MHz and the associated footnote regulatory provisions for AMS(R)S.

UNITED STATES
PRELIMINARY VIEWS ON WRC-ll
WRC-ll Agenda 1.2: taking into account the lTU-R studies carried out in accordance with
Resolution 951 (Rev.WRC-07), to take appropriate action with a view to enhancing the
international regulatory framework;
ISSUE: Identification of concepts and allocation procedures for enhancing the ITU Radio
Regulations (RR) to meet requirements of current and future radio applications while taking into
account existing services and usage;
BACKGROUND: WRC-07 considered the report of ITU studies in response to Resolution 951
(WRC-03) on methods to improve the international spectrum regulatory framework. This report
identified a number of options for addressing the evolution of radio applications, systems and
technologies which include the following:
Option 1: keeping the current service definitions and not introducing any changes to the lTU
Radio Regulations (RR) with respect to this agenda item;
Option 2: reviewing and possibly revising the current service definitions or adding one or more
new services to the list of service definitions, each one encompassing several of the existing ones;
Option 3: introducing a new provision in the RR enabling substitution between assignments of
specific services;
Option 4: introducing composite services in the Table of Frequency Allocations.
WRC-07 also adopted a revised version of Resolution 951, calling for urgent studies in order to
develop as appropriate, new concepts and procedures for enhancing the Radio Regulations to
meet the demands of current, emerging and future radio applications, while taking into account
existing services and usage. In particular, it calls for studies aimed at: a) evaluating options for
enhancing spectrum management solutions for increased flexibility in meeting new demands; b)
developing applicable concepts and procedures including sharing studies on a band-by-band basis
to support these options; c) preparing relevant technical and regulatory solutions for consideration
and appropriate action at WRC-l1.
DISCUSSION: The United States recognizes the importance of a spectrum regulatory framework
that allows flexible spectrum use, to the extent practicable, so as to allow for the evolution of
services and technologies, taking into account existing services and usage. Accordingly, the
United States has, consistently adopted domestic service rules to accommodate emerging
technologies, or, in various instances, sought changes in the ITU Radio Regulations in order to
accommodate new or evolving systems. These approaches have allowed the timely deployment of
new technologies. In either case, such changes have been sought after careful evaluation, on a
case-by-case basis, of the new service's requirements, and their ability to co-exist with other co 
frequency systems.
U.S. VIEW: The United States is of the view that support for proposals for enhancing the
international regulatory framework in specific situations should be evaluated using the guidelines
set forth in Annex 2 of Res. 951(WRC-07). The United States is also of the view that studies
should be conducted on a frequency band by frequency band basis consistent with the guidelines
30
in this Annex. The United States may consider supporting proposals under Agenda Item 1.2 on a
case by case basis, taking into account the guidelines in the Annexes to Resolution 951. The
United States does not support large-scale modifications to the international regulatory
framework since it believes that the current regulatory framework, including the WRC process, is
sufficiently flexible to accommodate new technologies.

DRAFT PROPOSALS FOR THE WORK OF THE CONFERENCE
WRC-11 Agenda Item 7: to consider possible changes in response to Resolution 86 (Rev.
Marrakesh, 2002) ofthe Plenipotentiary Conference: "Advance publication, coordination,
notification and recording procedures for frequency assignments pertaining to satellite
networks", in accordance with Resolution 86 (Rev. WRC-07)
Background information: Access to the geostationary orbit (GSa) has become increasingly
difficult over the years, in large part due to difficulties in fully coordinating new orbital positions
and applying the relevant provisions of the Radio Regulations. As highlighted at the most recent
ITU Radiocommunications Bureau (BR) workshop on efficient use of the spectrum/orbit resource
and in ITU administrative circular CRl301, it has been noted that some unused frequency and
GSa resources remain recorded in the Master International Frequency Register, which serves to
worsen this problem. As such, improving transparency into actual usage of frequency and GSa
resources could help to improve this situation.
For non-planned satellite bands, No. 11.44 of the Radio Regulations (RR) requires that the
notified date of bringing into use of any assignment to a space station of a satellite network shall
not be later than seven years following the date of receipt of the relevant complete information
under RR No. 9.1 or 9.2, as appropriate. Additionally, this provision states that any frequency
assignment not brought into use within the required period shall be cancelled by the BR. When
the notified date of bringing into use of frequency assignments is earlier than the date of
submission of the Notification request, the Notification request itself is considered by the BR as
confirmation that the frequency assignments have been brought into use. Furthermore, RR No.
11.47 clarifies the requirement for administrations to inform the BR of frequencies assignments
brought into use for the case of assignments being Notified before being brought into use.
Therefore, it can be considered that there are two separate requirements. Under the first, the BR
must receive the Notification information for frequency assignments in a network by the end of
the regulatory lifetime of the satellite network filing, whereas under the second the BR must have
been informed that the frequency assignments have actually been brought into use by a date
certain.
The potential difficulty with the current process is that it can result in uncertainty for
administrations as to the status of frequency assignments for several reasons. For example, while
administrations can examine the SRS database for details pertaining to notified frequency
assignments that have been submitted to the BR (Part I-S), or examined by the BR and found to
be in conformity with the Radio Regulations (Part II-S), they cannot readily determine whether or
not administrations have informed the BR that frequency assignments have been brought into use,
and if so the date on which they were brought into use. This can result in uncertainty for
administrations as to the provisional or definitive status of frequency assignments in the MIFR, or
whether an administration has missed the deadline under RR No. 11.44 entirely and it is simply a
matter of time before the provisionally notified frequency assignments are suppressed.
Additionally, there is currently no specific requirement to inform the BR within a specified time
limit that frequency assignments have actually been brought into use. As such, assignments can
be brought into use on a given date and the Notification information for these assignments can be
32
submitted to the BR at any later date, provided that the date of that submission is earlier than the
end of the time limit for notifying the network.
The uncertainty associated with frequency assignments and satellite networks actually brought
into use can be addressed by requiring administrations to inform the BR within a specified time
period that frequency assignments associated with a satellite network have actually been brought
into use and by having the BR make information received from administrations regarding such
bringing into use publicly available. The BR has established, on a trial basis, two web pages for
providing such information: http://www.itu.int/ITU-Rlspace/snIllistinuse/ for non-planned bands
and http://www.itu.int/ITU-Rlspace/snIllistinuse plan/ for planned bands. The BR should be
instructed to continue to build the list of networks contained on these pages and to make these
pages permanent. In addition, it would also be useful if, on this same web page, a hyperlink were
included to the Resolution 49 information associated with the bringing into use of the frequency
assignments in question.
In addition to the uncertainty associated with frequency assignments and satellite networks
actually brought into use, there can also be uncertainty associated with the Annex 2 data of
Resolution 49. This is due to the fact that Resolution 49 calls for data to be submitted as early as
possible before the end of the regulatory lifetime of the filing, or as early as possible before
satellite launch and, for a variety of reasons, it is possible for certain of these data elements to
change after such initial submission of the data. Such changes add to the uncertainty associated
with the GSa resources actually being used by administrations.
In order to address the uncertainties associated with Resolution 49 data, it is proposed to modify
this Resolution. The proposed changes entail requiring submission of Resolution 49 data only
after the BR has been informed that frequency assignments have been brought into use. In this
way, the Resolution 49 data would become definitive as there will be certainty associated with the
data called for in Annex 2 of the Resolution (i.e. launch date, launch provider, name of satellite,
frequency bands on the satellite, etc.).
Proposal:
USA/xxiI MOD
The uncertainty associated with frequency assignments and satellite networks actually brought
into use could be addressed as follows:
11.44 The notified date
20
of bringing into use of any assignment to a space station of a
satellite network shall be not later than seven years following the date of receipt by the Bureau of
20 11.44.1 In the case of space station frequency assignments that are brought into use prior to the
completion of the coordination process, and for which the Resolution 49 (Rev.WRC-12W)!I'. data have
been submitted to the Bureau, the assignment shall continue to be taken into consideration for a maximum
period of seven years from the date of receipt of the relevant information under No. 9.1. Ifthe first notice
for recording of the assignments in question under No. 11.15 has not been received by the Bureau by the
end of this seven-year period, the assignments shall no longer be taken into account by the Bureau and
administrations. The Bureau shall inform the notifying administration of its pending actions three months in
advance.
In the case of satellite networks for which relevant advance publication information has been received prior
to 22 November 1997, the corresponding period will be nine years from the date of publication of this
information. (WRC-2000)
33
the relevant complete information under No. 9.1 or 9.2, as appropriate. Any frequency assignment
not brought into use within the required period shall be cancelled by the Bureau after having
informed the administration at least three months before the expiry of this period. (See also
Resolution 49 (WRC-12)). (WRC-WJ.2)
USAlxx/2 MOD
11.47 All frequency assignments notified in advance of their being brought into use
shall be entered provisionally in the Master Register. Any frequency assignment to a space station
provisionally recorded under this provision shall be brought into use no later than the end of the
period provided under No. 11.44. Any other frequency assignment provisionally recorded under
this provision shall be brought into use by the date specified in the notice, or by the end of the
extension period granted under No. 11.45, as the case may be. Unless the Bureau has been
informed by the notifying administration of the bringing into use of the assignment, it shall, no
later than fifteen days before either the notified date of bringing into use, in the case of an earth
station, or the end of the regulatory period established under No. 11.44 or No. 11.45, as
appropriate, send a reminder requesting confirmation that the assignment has been brought into
use within that regulatory period. Ifthe Bureau does not receive that confirmation within thirty
days following the notified date of bringing into use, in the case of an earth station, or the period
provided under No. 11.44 or No. 11.45, as the case may be, it shall cancel the entry in the Master
Register. The Bureau shall, however, inform the administration concerned before taking such
action. (See also Resolution 49 (WRC-12)). (WRC-W-J.2)

RESOLUTION BIU
Publication of bringing into use data for satellite networks
The World Radiocommunication Conference (Geneva, 2012),
considering
a) that access to the geostationary orbit (GSa) has become increasingly difficult over the
years;
b) that this difficulty is due, in large part, to difficulties in fully coordinating new orbital
positions and applying the relevant provisions of the Radio Regulations;
c) that it has been noted that unused frequency and GSa resources remain recorded in the
Master International Frequency Register, and this further adds to the difficulty in accessing the
GSa;
d) that it is currently cumbersome, and in some cases not possible, for administrations to
determine if the Bureau has been informed that frequency assignments associated with a given
satellite network have been brought into use;
e) that improving the ability of administrations to identify the networks for which the
Bureau has been informed have been brought into use would help to address some of the
aforementioned difficulties;
f) that a readily accessible website, maintained by the Bureau, on which information related
to the date of bringing into use of satellite networks is displayed would improve the access to this
information by administrations,
resolves to instruct the Director ofthe Radiocommunications Bureau
1 to take the necessary steps to create a website, as part of the Bureau's collection of
web pages, on which data pertaining to the bringing into use of frequency assignments associated
with specific satellite networks is displayed;
2 upon receipt from an administration of information indicating the date of bringing
into use of frequency assignments associated with a particular satellite network, to include the
information associated with this indication on this website along with an indication as to whether,
in the Bureau's view, the frequency assignments are confirmed as being brought into use;
3 to also include on this website other pertinent information that will allow a unique
correlation of the indication that frequency assignments have been brought into use with a
particular satellite network;
4 to include on this website a hyperlink to the associated Resolution 49 data, submitted on
or after the date of bringing into use, for the particular frequency assignments and satellite

Administrative due diligence applicable to some satellite
radiocommunication services
The World Radiocornrnunication Conference (Geneva, 20129+),
considering
a) that Resolution 18 of the Plenipotentiary Conference (Kyoto, 1994) instructed the
Director of the Radiocommunication Bureau to initiate a review of some important issues
concerning international satellite network coordination and to make a preliminary report to
WRC-95 and a final report to WRC-97;
b) that the Director of the Bureau provided a comprehensive report to WRC-97, including a
number of recommendations for action as soon as possible and for identifying areas requiring
further study;
c) that one of the recommendations in the Director's report to WRC-97 was that
administrative due diligence should be adopted as a means of addressing the problem of
reservation of orbit and spectrum capacity without actual use;
d) that experience ma)' need to be gained in the application of the administrative due
diligence procedures adopted by WRC-97 indicates certain changes should be made to those
procedures, and that se't'eral years may be needed to see 't','hether administrative due diligence
measures produce satisfactory results;
e) that new regulatory approaches may need to be carefully considered in order to avoid
adverse effects on networks already going through the different phases of the procedures;
f) that Article 44 of the Constitution sets out the basic principles for the use of the radio-
frequency spectrum and the geostationary-satellite and other satellite orbits, taking into account
the needs of developing countries,
considering further
g) that WRC-97 decided to reduce the regulatory time-frame for bringing a satellite network

UNITED STATES OF AMERICA
DRAFT PROPOSAL FOR WRC-ll
AGENDA ITEM 7: to consider possible changes in response to Resolution 86 (Rev. Marrakesh,
2002) of the Plenipotentiary Conference: "Advance publication, coordination, notification and
recording procedures for frequency assignments pertaining to satellite networks", in accordance
with Resolution 86 (Rev.WRC-07)
ISSUE: Application of Nos. 9.51 and 9.52 with respect to coordination under No. 9.7
BACKGROUND: After a Coordination Request is submitted to the lTD, the Bureau
identifies the administrations with which coordination has to be effected. Within four
months of the publication of the Coordination Request each of the identified
administrations has to either agree with the coordination or explicitly express its
disagreement. Almost without exception, administrations choose the second option. This
proposal contains the necessary changes to the Radio Regulations in order to ensure that
lack of response from an administration is understood by the Bureau as disagreement and
therefore eliminate a significant amount of correspondence that in most cases does not
contribute in any way to expedite the coordination process.
For sake of discussion assume that the coordination request of a network of administration A has
been published and that administration B has been identified by the Bureau under No. 9.7 as one
of the administrations with which coordination has to be effected.
Then, according No. 9.51, administration B, within four months of the publication of the
coordination request, shall "either inform the requesting administration of its agreement or act
under No. 9.52", with the latter meaning that administration B will express its disagreement, i.e.
the need for coordination.
In the vast majority of cases, administrations respond in accordance with No. 9.52 without
providing any reasons for their disagreement. It is certainly the easiest and safest way to proceed.
It follows from the above that the required formal answer under Nos. 9.51 or 9.52 has lost its
value in the framework of GSa to Gsa coordination. An improvement to this aspect of the
process can be realized by lifting the mandatory nature of this requirement for coordination
requests made under No. 9.7 (GSa vs. Gsa).
In an improved process, after the coordination request of a satellite network of administration A is
published together with the initial list of administrations and corresponding provisional list of
satellite networks with which coordination has to be effected, administrations would review this
list. In case an administration wants to add or remove itself and/or a network, then it would send
this request to the Bureau, as well as to administration A, within four months of the date of
publication of the coordination request. However, if an administration agrees with the initial list
of administrations and provisional list of corresponding networks published by the Bureau, no
action would be required. In particular, an administration already included in the list would not
42
be removed from the final list due to lack of response under No.9.52 as such lack of a response
would be understood by the Bureau to mean that this administration believes that coordination
with one or more of its networks is required. Removing the requirement to respond under No.
9.52 will eliminate a significant amount of correspondence that in most cases does not contribute
in any way to expedite the coordination process.
U.S. PROPOSAL: In view of the above the United States proposes that changes to Article 9 of
the Radio Regulations be introduced in order to allow that: (1) if an administration, in respect to a
coordination request from another administration, is not in a position to give its agreement under
No. 9.51 then this administration would not need to respond to such a request; and (2) the lack of
such a response would be understood by the Bureau to mean that this administration believes that
coordination with one or more of its networks is required.
43
Annex 2
Proposed Modifications to Some Provisions of the Radio Regulations
MOD
9.51 Following its action under No. 9.50, the administration with which coordination
was sought under Nos. 9.7 to 9.7B shall, within four months of the date of publication of the BR
IFIC under No. 9.38 or its addenda published under No. 9.42, respectively, either inform the
requesting administration and the Bureau of its agreement or act under No. 9.52.
Reason: To explicitly state that different 4-month windows apply to the original publication and
each ofits addenda published within orjust after the first 4-month period.
MOD
9.52 Ifan administration, following its action under No. 9.50, does not agree to the
request for coordination, it shall, within four months of the date of publication of the BR IFIC
under No. 9.38, or of the date of dispatch of the coordination data under No. 9.29, inform the
requesting administration of its disagreement and shall provide information concerning its own
assignments upon which that disagreement is based. It shall also make such suggestions as it is
able to offer with a view to satisfactory resolution of the matter. A copy of that information shall
be sent to the Bureau. 24A Where the information relates to terrestrial stations or earth stations
operating in the opposite direction of transmission within the coordination area of an earth
station, only that information relating to existing radiocommunication stations or to those to be
brought into use within the next three months for terrestrial stations, or three years for earth
stations, shall be treated as notifications under Nos. 11.2 or 11.9.
Reason: To indicate that the following footnote is added:
ADD
24A
9.52.1 In the case of coordination requests under No. 9.7, an affected
administration not responding under Nos. 9.51 or 9.52 within four months of the date of
publication of the BR IFIC made under No.9.38 shall continue to be regarded as an affected
administration. The fact that this administration did not reply under No.9.52 will be considered as
a confirmation - for its part - of the BR publication and will not change its status under No. 9.36
nor the list of its networks established under No. 9.36.2.
Reason: This footnote to No. 9.52 lifts the mandatory nature ofmaking comments under No. 9.52
for the coordination category ofNo.9. 7 (GSO/GSO). A non-reply will be understood as a
confirmation ofthe BR IFIC publication made under No. 9.38, with respect to the list ofaffected
administrations (No. 9.36) and the list ofsatellite networks compiled under No. 9.36.2.
44
MOD
9.60 If, within the same four-month period specified in Nos. 9.51 or 9.51A, an administration
with which coordination is sought under Nos. 9.7A te-or 9.7B aRd-or 9.15 to 9.19 fails to reply or
to give a decision under Nos. 9.51 or 9.51A or, following its disagreement under No. 9.52, fails to
provide information concerning its own assignments on which its disagreement is based, the
requesting administration may seek the assistance of the Bureau. The administration initiating the
coordination under No. 9.7 may also request the assistance of the Bureau when this
administration considers that any of the affected administrations is not willing to participate in the
coordination process or does not want to cooperate in the resolution of the problems in the
manner foreseen under No. 9.53.
Reason: As the new provision footnote No. 9.52.1 above proposes to lift the mandatory nature of
No. 9.52for the coordination category ofNo. 9.7 (GSO/GSO), this category has to be excluded
from the currentformulation ofNo. 9.60. However, the possibility for the initiating
administration to ask the Bureau's assistance in case ofdifficulties should be maintained.
MOD
9.62 Ifthe administration concerned sttH-fails to respond within thirty days of the
Bureau's action under No. 9.61, the provisions of Nos. 9.48 and 9.49 shall apply.
Reason: The word "still" is not applicable to the situation addressed in the last sentence ofthe
modified No. 9.60.

UNITED STATES OF AMERICA
DRAFT PROPOSAL FOR WRC-ll
AGENDA ITEM 7: to consider possible changes in response to Resolution 86 (Rev. Marrakesh,
2002) of the Plenipotentiary Conference: "Advance publication, coordination, notification and
recording procedures for frequency assignments pertaining to satellite networks", in accordance
with Resolution 86 (Rev.WRC-07)
ISSUE: List of networks with which coordination needs to be effected (No. 9.36 of RR)
BACKGROUND: For the coordination between geostationary satellite networks (No.
9.7), the Bureau identifies the administrations with which coordination has to be effected
as well as the respective satellite networks. However, the list of identified satellite
networks is for information only. Coordination would be facilitated if, after receiving
comments from all interested administrations, the Bureau would render definitive the list
of networks with which coordination has to be effected. This proposal contains the
necessary changes to the Radio Regulations in order to achieve this goal.
The regulations currently in force - namely provisions Nos. 9.36 and 9.36.2 - indicate that the
Bureau, when it examines a request for coordination in application of Nos. 9.34 - 9.38, shall
identify any administration with which coordination may need to be effected.
Provision No. 9.36.2 further specifies that "in the case ofcoordination under Nos. 9.7, 9.7A and
9.7B, the Bureau shall also identify the specific satellite networks or earth stations with which
coordination needs to be effected. In the case ofcoordination under No.9. 7 the list ofthe
networks identified by the Bureau under No. 9.27 is for information purposes only, to help
administrations comply with this procedure. "
In this context, for sake of discussion assume that the coordination request of a network of
administration A has been published and that administration B has been identified by the Bureau
under No. 9.7 as one of the administrations with which coordination has to be effected.
As the list of the satellite networks of administration B provided by the Bureau is "for
information purposes only", administration A will not necessarily know the complete list of
networks of administration B that have to be considered until bilateral coordination between A
and B is conducted. This is not desirable, especially because detailed coordination is often
conducted between operators, whereas satellite networks are submitted to the ITD by
administrations. Operator-to-operator coordination agreements are subsequently ratified by the
administrations involved and a formal coordination meeting between administrations may never
happen. Therefore the operator of administration A associated with the satellite network under
consideration may never know the complete list of networks of administration B with which
coordination is required.
Provision No. 9.36.2 stipulates that the Bureau identifies the satellite networks with which
coordination needs to be effected in the framework of the coordination procedure foreseen in
Article 9 (Section II) for the coordination forms 9.7 to 9.7B. The Bureau uses for this
46
identification either the "coordination arc" (CA) concept or the method described in Appendix 8
(t1.TIT> 6%). On the above basis, the BR establishes the list of affected administrations (No.
9.36) and a list of satellite networks which may be affected by the network contained in the
"incoming" coordination request. The latter list, however, may not be complete or definitive for a
given coordination request. Under the provisions of No. 9.41 the administrations which are not
included in the list under No. 9.36 may request their inclusion in this list, identifying networks
outside the coordination arc for whjch the value of t1.TIT calculated by the method in Appendix 8
exceeds 6%.
In addition, administrations which are included in the list of 9.36 may at a later time request that,
in addition to the networks included in the list of No. 9.36.2, other networks should also be
included in the coordination process. The latter case does not seem to be covered by the
provisions of No. 9.41 which treats only cases of administrations not included in the first list
established under No. 9.36 rather than the networks. Consequently, this problem needs to be
solved by the admjnistrations during bilateral coordination discussions. A further difficulty is that
the additions under No. 9.41 to the list of the affected administrations can only be handled by
addenda to the BR first publication under No. 9.38 at different times, after the first publication
(see Nos. 9.41 and 9.42). While the additionally affected administrations are in this way
published and consequently known by all the administrations after the 4 month comment period,
the complete list of networks to be considered is not available, as the list of networks originally
published under No. 9.36.2 is not updated.
Having experienced the above difficulties, a Rule of Procedure (RoP) concerning the application
of Provisions Nos. 9.41 and 9.42 has been established. This RoP is attached to the present
document for information. (Annex 1). The RoP recognizes that under the current regulations the
list of affected networks (No. 9.36.2) cannot be considered as exhaustive. In addition, it is also
recognized that when administrations disagree on the list of networks to be considered the
problem can only be solved by the Bureau at the very end of the notification process (Article 11,
Nos. 11.32A, and probably 11.41)
It is noted that the wording of No. 9.41 excludes from its application those administrations which
have been selected for inclusion in the list of affected administration under No. 9.36. These
administrations may also find that some of their networks which were not included in the list of
No. 9.36.2 - since they were outside the coordination arc - should be included into the
coordination procedure as their t1.TIT value exceeds the threshold value of 6%. Logically for these
administrations the concept of No. 9.41 should also apply. The current Rule of Procedure on
Nos. 9.41- 9.42 recognizes this problem (see §.2.1 of the RoP in Annex 1) and suggests that such
cases should be considered under No. 9.52 (disagreement communicated to the initiating
administration). For such a case the Rule states that the administration should, "while applying
No. 9.52 and without having to apply No. 9.41, bring into the bilateral coordination discussion
any oftheir networks located outside the coordination arc which meet the iJTfT > 6% criterion. "
In view of the above considerations, it seems logical and necessary to open the application of the
concept of No. 9.41 also for those administrations which have already been identified as affected
administrations under No. 9.36, to allow for the possible addition of networks which were not
identified under No. 9.36.2 where the only criterion applied was the coordination arc.
In summary, an improvement to the process would be for the list of networks identified under
No. 9.36.2 with respect to coordination under No. 9.7 to be considered provisional and not "for
information only". Currently, according to No. 9.41, within the period of four months following
the publication of a coordination request, administrations are able to request that an
administration be added or removed from the list generated by the Bureau. In an improved
process, this possibility would be expanded so that requests could also be made to add or remove
47
networks from the list generated by the Bureau.' The Bureau would then study all these requests
(see No. 9.42) and subsequently publish, at the earliest possible date, a definitive list of
administrations and corresponding satellite networks with which coordination would be required.
Consequential changes to Article 9 and Appendix 5 of the Radio Regulations will be required in
order to implement these proposals.
u.s. PROPOSAL: In view of the above the United States proposes that changes to Article 9 and
Appendix 5 of the Radio Regulations be introduced in order to allow that a definitive list of
administrations and corresponding satellite networks with which coordination needs to be
effected be generated as early as possible in the coordination process. These changes are
specified in Annex 2.
Requests for addition of an administration should also include the specification of the networks of
this administration to be considered in the coordination.
48
Annex 1
Extracts from the Rules of Procedure
~9.41 - 9.42 i
1 The Board has closely studied the situation and the reasons that led to the adoption of the
coordination arc (CA) principle at WRC-2000 and in particular Nos. 9.41 and 9.42. In doing so,
it was guided by recognizing and considering of Resolution 55 (WRC·2000), by Article 9 in
general, and by Nos. 9.36, 9.36.2 and Appendix 5.
2 The Board has accordingly arrived at the following conclusions regarding the application
of the provisions of No. 9.41 by an administration which considers that its name should have been
identified under No. 9.36 in the context of a request for coordination stemming from the
application of No. 9.7 (including for cases not having to do with application of coordination arc):
2.1 Once an administration has been identified and included in the coordination
requirements of a particular assignment published in a coordination special section,
coordination is to be effected between administrations (not between networks) who
decide, based on Appendix 5, which networks they wish to take into account in their
bilateral discussions. The list of satellite networks published under No. 9.36.2 is intended
for information purposes only, and thus should not be considered as exhaustive.
Administrations identified on the basis of CA can, while applying No. 9.52 and without
having to apply No. 9.41, bring into the bilateral coordination discussions any of their
networks located outside of the coordination arc which meet the fj,TlT > 6% criterion. In
this case, no action is undertaken by the Bureau under No. 9.42.
2.2 Administrations not identified by CA are entitled, based on the fj,T/T > 6%
criterion, to be included in coordination, in application of Nos. 9.41 and 9.42. Requests
under No. 9.41 must be substantiated by fj,T/T > 6% calculations. To minimize the
administrative burden on the Bureau and administrations, it shall be deemed sufficient for
an administration wishing to be added in a coordination request under No. 9.41 to provide
fj,T/T> 6% calculations for only one pair of assignments for each satellite network to be
further considered in the coordination process (a pair consisting of one assignment of the
published network and one assignment of the network of the requesting administration);
the Bureau will then examine all assignments of the specific networks of the requesting
administration and then establish coordination requirements for all the assignments of the
network referred to in the publication vis-a.-vis the requesting administration under
No. 9.42 commensurate with the results of such examination.
3 In case of continuing disagreement between the administration of the published network
and an administration involved in coordination under Nos. 9.7 or 9.42, which cannot be resolved
between them at coordination stage, the two administrations may communicate to the Bureau
a mutually agreed list of networks to be taken into account for examination under No. 1l.32A at
notification stage. Ifthe two administrations cannot agree on such a list, the Board decided that
examination under No. 11.32A at notification stage will be carried out with respect to all
networks of the latter administration, indicated in application of § 2 of this Rule, whose
assignments, identified in accordance with § 1 of Appendix 5, have /)'T/T greater than 6%.

Annex 2
Proposed Modifications to Some Provisions of the Radio Regulations
MOD
21 9.36.2 In the case of coordination under Nos. 9.7, 9.7A and 9.7B, the Bureau shall
also identify the specific satellite networks or earth stations with which coordination
needs to be effected. (See also No. 9.42.1.) In the case of coordination under No. 9.7 the
list of the netv/orks identified by the Bureau under No. 9.27 is for information purposes
only, to help administrations comply with this procedure.
Reason: To make the list ofaffected networks an exhaustive, official listfor the
coordination under 9.7and therefore avoid unnecessary discussions between
administration concerning the status ofthe assignments/networks which are to be
included or not in the bilateral coordination negotiations. According to the addition
proposed under No. 9.42.1 hereafter this list will be updated after each action under Nos.
9.41-9.42, and at the end ofthis procedure, will be made available to the administrations
as an exhaustive and official list ofnetworks with which coordination needs to be
effected.

administration believing that an administration or any of its networks identified under No. 9.36 in
accordance with the provisions of No. 9.7 (GSa/GSa) (items 1) to 8) of the frequency band
column), No. 9.7A (GSa earth station/non-GSa system) or No. 9.7B (non-GSa system/GSa
earth station) of Table 5-1 of Appendix 5 should not have been included in the request, shall,
within four months of the date of publication of the relevant BR IFIC, inform the initiating
administration or the identified administration, as appropriate, and the Bureau, giving its technical
reasons for doing so, and shall request that its name and the complete associated list of its
networks be included or that the name of the identified administration or any of its networks be
excluded, as appropriate.
Reason: To allow the initiating administration to propose changes not only to the list of
administrations identified by the BR but also to the list ofnetworks associated with these
administrations. To require that an administration that wants to be included in the
coordination, but has not been identified by the BR, also identify all ofits specific
networks to be considered.
ADD
9.41A Following receipt of the BR !FIe referring to requests for coordination
under Nos. 9.7 to 9.7B, an administration already identified under No. 9.36 as an affected
administration, may propose changes to the list of its networks provisionally identified by
the BR. In particular, if this administration considers that the value of f..T/T calculated by
the method in § 2.2.1.2 and 3.2 of Appendix 8 exceeds 6% for some other network(s)
outside the coordination arc in addition to those included in the provisional list of
networks under No. 9.36.2, it may request the inclusion of this (these) other network(s) in
the list. This administration shall, within four months of the date of publication of the
50
relevant BR !FIC, inform the initiating administration and the Bureau of any proposed
changes to the list established under No. 9.36.2, giving its technical reasons for doing so.
Reason: To make available for administrations already identified as affected
administration under No. 9.36 (because oftheir networks within the coordination arc)
the possibility ofadding networks outside the coordination arc provided the trigger level
off1T/T is exceededfor these networks and ofproposing any other changes to the list of
networks identified by the BR.
MOD
9.42 The Bureau shall studyth~tsinformation received under Nos. 9.41 and 9.41A on
the basis of Appendix 5 and shall inform both administrations of its conclusions. Should the
Bureau agree to include or exclude, as appropriate, the administration and/or associated networks
in the request, it shall publish an addendum to the publication under No. 9.3S
22A
Reason: To make explicit reference to the two preceding provisions as now both are concerned
and that inclusions and exclusions to the list may refer to administrations and/or networks.
Reason: To update the list originally established under No. 9.36.2 with the inclusions and/or
exclusions ofadministrations and/or networks submitted by administrations under Nos. 9.41 and
9.4lA and considered justifiable after studied by the BR under No. 9.42. The administration may
use this list in their coordination negotiations as an exhaustive list of networks with which
coordination has to be effected.
ADD
9.43A The list of networks identified for those administrations not responding under
No. 9.41A within the time limit specified therein shall be regarded as definitive.
Reason: To make explicit that lack ofa reply from an administration under No. 9.4lA will be
understood by the BR as agreement ofthat administration with its inclusion in the provisional list
as well as with the associated list ofits networks.

United States of America
DRAFT PROPOSALS FOR THE WORK OF THE CONFERENCE
Agenda Item 8.2: to recommend to the Council items for inclusion in the agenda for the
next WRC, and to give its views on the preliminary agenda for the subsequent conference and on
possible agenda items for future conferences, taking into account Resolution 806 (WRC 07).
Background information
In Resolution 806 (WRC-07), "Preliminary agenda for the 2015 World Radiocommunication
Conference," WRC-07 included preliminary Agenda Item 2.2 dealing with the review of the use
of the band 5091-5150 MHz by the fixed-satellite service (FSS) for feeder links to non-GSO,
mobile-satellite service systems.
At WRC-95, allocation was made to the fixed-satellite service in the 5091-5150 MHz band for
feeder links to non-GSO mobile-satellite service systems, in the Earth-to-space direction, on a
primary basis under No. 5.444A.
The 5091-5150 MHz band was originally designated for expansion of the international standard
Microwave Landing System (MLS) and Recommendation ITU-R S.1342 describes a method for
determining coordination distances between international standard MLS stations operating in the
band 5030-5090 MHz and FSS stations providing Earth-to-space feeder links in the 5091-5150
MHz band.
At WRC-07, an additional allocation was made, in the 5091-5150 MHz band, to the aeronautical
mobile service (AMS) for use by aeronautical telemetry for flight test, aeronautical mobile (route)
service and aeronautical security applications. Compatibility between the newly allocated
aeronautical mobile service planned usage and the existing fixed-satellite service usage was
demonstrated by extensive studies carried out by the ITU-R in the lead up to WRC-07.
This allocation is currently used by the HIBLEO-4FL network and has been used compatibly with
other services since 1998. The extensive studies undertaken in preparation for WRC-07 resulted
in the creation of No. 5.444B and Resolutions 748(WRC-07), 418(WRC-07) and 419(WRC-07)
and demonstrated compatibility between the fixed-satellite service and the aeronautical mobile
(route) service, the planned usage by the aeronautical mobile service used for aeronautical
mobile telemetry for flight test, and aeronautical security transmissions, respectively.
The operator of the HIBLEO-4FL network has embarked on the replenishment of its satellite
constellation with the expected entry into service of new spacecraft during 2010. As these new
spacecraft will be replacements for existing equipment, they will also utilize the 5091-5150 MHz
range for feeder links in the Earth-to-space direction. The replacement satellites are expected to
remain in service beyond the year 2025.
As a result of these developments, continued FSS use of the 5091-5150 MHz band for feeder
links of the MSS, Earth-to-space, is required. Taking into account the time constraints contained
in No. 5.444A, it is necessary to comply with Resolution 114 (WRC-03) prior to 2018.
Recognizing the considerable effort expended in studying the compatibility between feeder links,
Earth-to-space, for MSS systems and the Aeronautical Mobile Service in preparation for WRC 
07, and since the interference budgets and scenarios studied before remain the same for the
HIBLEO-4FL replacement spacecraft, study of technical and operational issues can and should be
limited to the sharing of this band between new systems of the aeronautical radionavigation
service and the FSS providing feeder links of the non-GSO systems in the MSS.
53
The continued use of this allocation by feeder uplinks is of great importance in providing
continuing service by MSS systems to developing countries, under-served areas and critical
response in the event of natural disasters and other civil emergencies.
Proposal:
Agenda Item 8.2
RESOLUTION 806 (WRC-07)
Preliminary agenda for the 2015 World
Radiocommunication Conference
NOCUSMx~l
2.2 to review the use of the band 5091-5 150 MHz by the fixed-satellite
service (Earth-to-space) (limited to feeder links of the non-GSa mobile-satellite service) in
accordance with Resolution 114 (Rev.WRC-03);
Reasons: Maintaining this item on the Agenda for the 2015 World Radiocommunication
Conference will allow studies of compatibility between the aeronautical radionavigation service
and FSS feeder links of non-GSa mobile-satellite service systems and allow uninterrupted
operation of MSS systems into the future.
