ATTACHMENT 2 to FCC Public Notice DA 10-1408 Draft Proposals formulated and approved within the National Telecommunications and Information Administration: 2 Document WAC/068(28.07.10) Ms. Mindel De La Torre Chief of the International Bureau Federal Communications Commission 445 12 th Street SW Washington, DC 20554 Dear Ms. De La Torre: The National Telecommunications and Information Administration (NTIA) on behalf of the Executive Branch agencies, approves the release of two draft Executive Branch proposals for WRC-12 agenda items 1.6 (Resolution 950) and 1.10. For agenda item 1.6 (Resolution 950), NTIA proposes to modify No. 5.565 to update the list of use of 275 – 3 000 GHz by the passive services. NTIA also proposes a mobile-satellite service (Earth-to-space) allocation for Appendix 18 Channels 75 and 76 to improve satellite detection of the Automatic Identification System under agenda item 1.10. NTIA considered the Federal agencies’ input toward the development of U.S. proposals for WRC-12. NTIA forwards this package for your consideration and review by your WRC-12 Advisory Committee. Dr. Darlene Drazenovich is the primary contact from my staff. Sincerely, (Original Signed February 25, 2010) Karl B. Nebbia Associate Administrator Office of Spectrum Management 3 UNITED STATES OF AMERICA DRAFT PROPOSAL FOR THE WORK OF THE CONFERENCE Agenda Item 1.6: to review No. 5.565 of the Radio Regulations in order to update the spectrum use by the passive services between 275 GHz and 3 000 GHz, in accordance with Resolution 950 (Rev.WRC 07), and to consider possible procedures for free-space optical-links, taking into account the results of ITU R studies, in accordance with Resolution 955 (WRC 07) Background Information: Agenda item 1.6 addresses two distinct issues. The content of this proposal addresses only the updating of No. 5.565 in accordance with Resolution 950 (Rev. WRC-07). The Table of Frequency Allocations establishes allocations at frequencies between 9 kHz and 275 GHz. No allocations currently exist above 275 GHz, although an entry in the Table for the range 275-1 000 GHz contains a reference to No. 5.565. Resolution 950 (Rev. WRC-07) calls for a re-examination of the frequency bands contained in No. 5.565 with a view to updating this footnote, including advice on the applications suitable for the range 275-3 000 GHz. Passive services such as the Earth exploration-satellite service (EESS), space research service (SRS), and radio astronomy service (RAS) already utilize portions of the 275-3 000 GHz range for scientific observation. Some of these operations measure spectral line and continuum emissions from space while others measure atmospheric and climate-related natural emissions from the Earth and its atmosphere. Resolution 950 (Rev. WRC-07) resolves to review No. 5.565 to update the information on spectrum use in the frequency range 275-3 000 GHz by the passive services, but specifically excludes allocations in this range. ITU-R studies of current and projected scientific needs for passive use of the frequency range 275-3 000 GHz resulted in new recommendations and reports. These studies revealed a need to update No. 5.565 through the addition of some new bands of interest and the deletion of some existing bands. Technical factors strongly influence use of the range 275-3 000 GHz. First, the Earth’s atmosphere absorbs signals at these frequencies, especially in the range 1 000-3 000 GHz where the atmosphere is nearly opaque. Second, antenna beamwidths are extremely narrow at such high frequencies. Interference from non-geostationary satellites into terrestrial stations is highly unlikely due to the above factors and the speed of the spacecraft relative to Earth. With regard to geostationary satellites, coordination would resolve the potential interference from the unlikely scenario of transmissions with maximum antenna coupling and minimum propagation loss. As a result, passive and active services can share frequencies above 1 000 GHz without constraints. 4 Proposal: ARTICLE 5 Frequency allocations Section IV – Table of Frequency Allocations (See No. 2.1) MOD USA/AI 1.6/1 5.565 A number of frequency bands in Tthe frequency band range 275-13 000 GHz may be are used by administrations for experimentation with, and development of, various active and passive services applications. In theis band frequency range 275-1 000 GHz a need has been identified for the following frequency bands for measurements by spectral line measurements for passive services: - radio astronomy service: 275-323 GHz, 327-371 GHz, 388-424 GHz, 426-442 GHz, 453- 510 GHz, 623-711 GHz, 795-909 GHz and 926-945 GHz; - Earth exploration-satellite service (passive) and space research service (passive): 275- 277286 GHz, 294296-306 GHz, 316313-334356 GHz, 342-349 GHz, 363361-365 GHz, 371369-389392 GHz, 397-399 GHz, 409-411 GHz, 416-434 GHz, 442439-444467 GHz, 496477-506502 GHz, 523-527 GHz, 546538-568581 GHz, 624611-629630 GHz, 634-654 GHz, 659657-661692 GHz, 684-692 GHz713-718 GHz, 730729-732733 GHz, 750-754 GHz, 771-776 GHz, 823-846 GHz, 851850-853854 GHz, 857-862 GHz, 866-882 GHz, 905-928 GHz, and 951-956 GHz, 968-973 GHz and 985-990 GHz. In the frequency range 1 000-3 000 GHz, passive services may use any band segment for ground- and space-based experimentation without constraints on any other services operating in this range. Future research in this largely unexplored spectral region may yield additional spectral lines and continuum bands of interest to the passive services. Administrations are urged to take all practicable steps to protect these passive services from harmful interference until the date when the allocation Ttable is established in the above-mentioned 275-3 000 GHz frequency rangeband. Reasons: Based on the studies performed, the list of EESS and SRS bands of interest in the range 275-1 000 GHz need to be updated in No. 5.565. ITU-R studies have shown that unconstrained sharing between passive and active services in the frequency range 1 000-3 000 GHz is feasible; therefore passive services should have use of any band segment in this frequency range for experimentation. SUP USA/AI 1.6/2 RESOLUTION 950 (Rev. WRC-07) Consideration of the use of the frequencies between 275 and 3 000 GHz Reasons: Required studies have been completed. The resolution is no longer needed. 5 UNITED STATES OF AMERICA DRAFT PROPOSALS FOR THE WORK OF THE CONFERENCE Agenda Item 1.10: to examine the frequency allocation requirements with regard to operation of safety systems for ships and ports and associated regulatory provisions, in accordance with Resolution 357 (WRC-07) Background Information: Modifying the Radio Regulations to reflect the satellite monitoring of Automatic Identification System (AIS) equipped vessels is critical to search and rescue, safety of navigation, and the safe movement and tracking of vessels. This proposal specifically adds a mobile- satellite service (MSS) (Earth-to-space) allocation to 156.775 MHz and 156.825 MHz (Appendix 18, Channels 75 and 76) for improved AIS satellite detection using message 27. This proposal satisfies the International Maritime Organization (IMO) Resolution MSC 74(69), which requires 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). Improved satellite detection of AIS will satisfy IMO functional requirements for collision avoidance, obtaining information about a ship and its cargo, and providing ship-to-shore traffic management. 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.[SAT-AIS], “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, 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. Precautions to avoid harmful interference to channel 16 are achievable by prohibiting message 27 transmissions within 40 nautical miles of coast stations. Therefore, the new proposed footnote r) is fully compliant with footnote n) in Appendix 18. 6 Proposal: ARTICLE 5 Section IV – Table of Frequency Allocations (See No. 2.1) MOD USA/AI 1.10/1 148-223 MHz Allocation to services Region 1 Region 2 Region 3 156.7625-156.8375 MARITIME MOBILE (distress and calling) 5.111 5.226 ADD 5.XYZ Reasons: Proposed changes reflect the allocation of 156.7625-156.8375 MHz to the required services in Article 5 to support maritime safety and vessel tracking requirements. ADD USA/AI 1.10/2 5.XYZ Additional allocation: the bands 156.775 MHz and 156.825 MHz are also allocated to the Mobile-Satellite Service (Earth-to-space) for the reception of automatic identification system (AIS) emissions, using solely message 27 as specified in Recommendation ITU-R M.1371, from stations operating in the maritime-mobile service (see Appendix 18). Reasons: Proposed changes reflect the allocation of 156.775MHz and 156.825 MHz to the required services in Article 5 to support maritime safety and vessel tracking requirements.

NTIA proposes modifications to Appendix 17 of the Radio Regulations, along with other changes, that would provide HF frequencies for new digital technologies in the maritime mobile service.

Dr. Darlene Drazenovich is the primary contact from my staff. Sincerely, (Original Signed March 17, 2010) Karl B. Nebbia Associate Administrator Office of Spectrum Management 10 UNITED STATES OF AMERICA DRAFT PROPOSALS FOR THE WORK OF THE CONFERENCE Agenda Item 1.9: to revise frequencies and channelling arrangements of Appendix 17 to the Radio Regulations, in accordance with Resolution 351 (Rev.WRC-07), in order to implement new digital technologies for the maritime mobile service Background Information: The introduction of new data exchange technologies 1 in the HF maritime mobile service is providing an alternative to narrow-band direct printing (NBDP) technology. According to the International Maritime Organization, current NBDP applications include maritime safety information (MSI) broadcasts, ship reporting, weather forecasts and business communications (e.g. fishing fleets). Since alternative data communication technologies for these functions are available, NBDP equipment use is in rapid decline. However, NBDP telegraphy remains essential for distress communications in the polar regions (sea area A4) where geostationary satellites cannot provide coverage and other terrestrial means of communication are unreliable. The global maritime community intends to improve efficiency and flexibility in the HF maritime mobile service spectrum by designating certain assignable frequencies in Appendix 17 to data transmissions using new data exchange technologies. This proposal would: 1) significantly reduce the number of NBDP frequencies to those actually used for NBDP telegraphy and the GMDSS/NBDP core frequencies (Appendix 15); 2) allow for the use of the current NBDP bands for digital data transmissions, subject to not claiming protection from nor causing harmful interference to other stations in the maritime mobile service using NBDP technology until December 31, 2014; 3) make new digital data transmissions primary in the current NBDP bands effective January 1, 2015, though stations could use NBDP technology subject to not claiming protection from nor causing harmful interference to stations in the maritime mobile service using digital data transmissions; 4) re-designate the frequencies currently assignable to stations using facsimile, wide-band telegraphy and Morse telegraphy A1A/A1B to stations using data transmission without a transition period; 5) neither specify nor limit the bandwidth of new digital transmissions; 6) allow stations using wide-band telegraphy or Morse telegraphy A1A/A1B to continue on their currently assigned frequencies subject to not claiming protection from nor causing harmful interference to stations in the maritime mobile service using digital data transmissions; 7) not modify Appendix 25 radiotelephony bands, but would allow for the use of digital data transmissions in the radiotelephony bands in accordance with the Appendix 25 allotment plan; and 8) provide some flexibility to administrations in portions of the bands 4 MHz, 6 MHz and 8 MHz to assign new simplex radiotelephony frequencies in accordance with No. 52.177, subject to not claiming protection from stations in the maritime mobile service using digital data transmissions. 1 See Recommendation ITU-R M.1798 Characteristics of HF radio equipment for the exchange of digital data and electronic mail in the maritime mobile service 11 Proposal: MOD USA/AI 1.9/1 APPENDIX 17 (Rev.WRC-0312) Frequencies and channelling arrangements in the high-frequency bands for the maritime mobile service (See Article 52) PART A – Table of subdivided bands (WRC-0312) In the Table, where appropriate 1 , the assignable frequencies in a given band for each usage are: – indicated by the lowest and highest frequency, in heavy type, assigned in that band; – regularly spaced, the number of assignable frequencies ( f.) and the spacing in kHz being indicated in italics.

NTIA proposes modifications to Appendix 18 (Rev. WRC-07) of the Radio Regulations, Table of transmitting frequencies in the VHF maritime mobile band. NTIA considered the Federal agencies’ input toward the development of U.S. proposals for WRC-12. NTIA forwards this package for consideration and review by your WRC-12 Advisory Committee. Dr. Darlene Drazenovich is the primary contact from my staff. Sincerely, (Original Signed April 12, 2010) Karl B. Nebbia Associate Administrator Office of Spectrum Management 26 UNITED STATES OF AMERICA DRAFT PROPOSALS FOR THE WORK OF THE CONFERENCE Agenda Item 1.10: to examine the frequency allocation requirements with regard to operation of safety systems for ships and ports and associated regulatory provisions, in accordance with Resolution 357 (WRC-07) Background Information: Simplex Use of Duplex Channels The Radio Regulations Board approved a Rule of Procedure after WRC-07 regarding simplex use in Appendix 18, effectively implementing this part of the enclosed proposal. WRC-07 revised Appendix 18 to allow simplex use of channels 01, 07, 19, 20, 21, 60, 66, 78, 79, 80, and 81 subject to coordination with affected administrations (Note m). However, WRC-07 omitted placing an "x" in the "Single frequency" column against affected channels in Appendix 18, thereby unintentionally omitting this from the Radio Regulations. Expansion of optional simplex use of duplex channels (add more “x” designations to duplex channels) in Appendix 18 will provide further benefits to maritime radiocommunications by relieving current congestion in the VHF maritime mobile bands in accordance with Recommendation ITU-R M.1084-4. Report ITU-R M.2010-1, a study on efficiency in the VHF maritime mobile band, concluded that this spectrum efficiency option expands the number of usable communications channels with the minimum of compatibility issues. The analogue VHF radio on board vessels that travel internationally would have access to both the original two-frequency channels and their single-frequency derivatives, thus allowing port operations on two or single frequency channels. Channels for E-Navigation (e-Nav) Designating in Appendix 18 six channels for E-Navigation (eNAV) * data exchange responds to the International Maritime Organization’s (IMO) E-Navigation initiatives for future VHF data exchange. Technical studies are ongoing within the International Association of Marine Aids to Navigation and Lighthouse Authorities (IALA) E-Navigation Committee with close coordination between IALA and the ITU-R. Recommendation ITU-R M.1842-1 provides examples of potential VHF E-Navigation systems and recommends the use of Appendix 18 channels for the exchange of data for E-Navigation to support future digital technologies in the maritime mobile service VHF bands. The ITU-R summarizes E- Navigation spectrum requirements in a liaison statement to IALA (5B/417 Annex 28) and proposes continued cooperative efforts between the two maritime organizations. Adding a new Note s) to the table of Appendix 18 and to the section “Notes referring to the Table” supports the identification six channels (24, 25, 26, and 27) for potential E-Navigation systems. Protection of Channels AIS 1 and AIS 2 Protecting the Automatic Identification System channels (AIS 1 and AIS 2) from harmful interference would ensure the future safety of maritime mobile radiocommunications for these channels. Report ITU- * eNAV – From IMO: “E-Navigation is the harmonised creation, collection, integration, exchange and presentation of maritime information onboard and ashore by electronic means to enhance berth to berth navigation and related services, for safety and security at sea and protection of the marine environment”. 27 R M.2122 “EMC assessment of shore-based electronic navigation (eNAV) infrastructure and new draft standards for data exchange in the VHF maritime mobile band (156-174 MHz)” describes the susceptibility of AIS 1 and AIS 2 to interference from the adjacent duplex channels. This Report also provides technical guidelines for the electromagnetic compatibility between AIS and systems that use channels 27 and 28. Thus, modifying Note c) in the section “Notes referring to the Table” of Appendix 18 is necessary for protecting AIS. Non-Application of Channel Interleaving Recommendation ITU-R M.1084-4 describes the advantages of increased spectrum efficiency by channel interleaving 12.5 kHz channels with 25 kHz channels. The current Appendix 18 excludes maritime mobile service safety channels from 12.5 kHz channel interleaving (See Note e)). By modifying Note e) in the section “Notes referring to the Table” of Appendix 18, the non- application of channel interleaving extends to the exclusion of AIS 1 and AIS 2, and the proposed channels for E-Navigation discussed above. Long-Range Detection of AIS Recommendation ITU-R M.1371-3 provides technical and operational characteristics for designing systems intended for long-range detection of AIS. Modifying Note n) in the section “Notes referring to the Table” of Appendix 18 identifies the use of AIS for long-range detection for channels 75 and 76 and ensures the protection of these channels from harmful interference. Proposal: MOD USA/AI 1.10/1 APPENDIX 18 (REV.WRC-0712) Table of transmitting frequencies in the VHF maritime mobile band (See Article 52) NOTE A – For assistance in understanding the Table, see Notes a) to q) below. (WRC-07) NOTE B – The Table below defines the channel numbering for maritime VHF communications based on 25 kHz channel spacing and use of several duplex channels, but and also allows the simplex use of 12.5 kHz channel spacingduplex channels. The channel numbering for 12.5 kHz channels and the conversion of two-frequency channels for single-frequency operation of duplex channels shall be in accordance with Recommendations ITU-R M.493 and 1084 (Latest versions)-4 Annex 4, Tables 1 and 3. (WRC-0712) Reasons: Proposed changes to NOTE B will allow for more flexibility for simplex (single- channel) use of duplex channels. 28 MOD USA/AI 1.10/2 Transmitting frequencies (MHz) Inter-ship Port operations and ship movement Channel designator Notes From ship stations From coast stations Single frequency Two frequency Public corres- pondence 60 m), o) 156.025 160.625 x x x 01 m), o) 156.050 160.650 x x x 61 m), o) 156.075 160.675 x x x 02 m), o) 156.100 160.700 x x x 62 m), o) 156.125 160.725 x x x 03 m), o) 156.150 160.750 x x x 63 m), o) 156.175 160.775 x x x 04 m), o) 156.200 160.800 x x x 64 m), o) 156.225 160.825 x x x 05 m), o) 156.250 160.850 x x x 65 m), o) 156.275 160.875 x x x 06 f) 156.300 x 66 m), o) 156.325 160.925 x x x 07 m), o) 156.350 160.950 x x x 67 h) 156.375 156.375 x x 08 156.400 x 68 156.425 156.425 x 09 i) 156.450 156.450 x x 69 156.475 156.475 x x 10 h), q) 156.500 156.500 x x 70 f), j) 156.525 156.525 Digital selective calling for distress, safety and calling 11 q) 156.550 156.550 x 71 156.575 156.575 x 12 156.600 156.600 x 72 i) 156.625 x 13 k) 156.650 156.650 x x 73 h), i) 156.675 156.675 x x 14 156.700 156.700 x 74 156.725 156.725 x 15 g) 156.750 156.750 x x 75 n) 156.775 156.775 x 29 Transmitting frequencies (MHz) Port operations and ship movement Channel designator Notes From ship stations From coast stations Inter-ship Single frequency Two frequency Public corres- pondence 16 f) 156.800 156.800 DISTRESS, SAFETY AND CALLING 76 n) 156.825 156.825 x 17 g) 156.850 156.850 x x 77 156.875 x 18 m) 156.900 161.500 x x x 78 m) 156.925 161.525 x x x 19 m) 156.950 161.550 x x x 79 m) 156.975 161.575 x x x 20 m) 157.000 161.600 x x x 80 m) 157.025 161.625 x x x 21 m) 157.050 161.650 x x x 81 m) 157.075 161.675 x x x 22 m) 157.100 161.700 x x x 82 m), o) 157.125 161.725 x x x 23 m), o) 157.150 161.750 x x x 83 m), o) 157.175 161.775 x x x 24 m), o), s 157.200 161.800 x x x 84 m), o), s 157.225 161.825 x x x 25 m), o), s 157.250 161.850 x x x 85 m), o), s 157.275 161.875 x x x 26 m), o), s 157.300 161.900 x x x 86 m), o), s 157.325 161.925 x x x 27 r) 157.350 161.950 x x 87 157.375 157.375 x 28 r) 157.400 162.000 x x 88 157.425 157.425 x AIS 1 f), l), p) 161.975 161.975 AIS 2 f), l), p) 162.025 162.025 Reasons: Proposed changes to the Table will allow for more flexibility for simplex (single- channel) use of duplex channels.

MOD USA/AI 1.10/4 e) Administrations may apply 12.5 kHz channel interleaving on a non-interference basis to 25 kHz channels, in accordance with the most recent version of Recommendation ITU-R M.1084, provided: – it shall not affect the 25 kHz channels of the present Appendix maritime mobile distress and safety, AIS, and E-Navigation data exchange frequencies, especially the channels 06, 13, 15, 16, 17, and 70, 24, 25, 26, 84, 85, 86, AIS 1 and AIS 2, nor the technical characteristics set forth in Recommendation ITU-R M.489-2 for those channels; – implementation of 12.5 kHz channel interleaving and consequential national requirements shall be subject to coordination with affected administrations. (WRC-07) Reasons: Proposed changes to Note e) identify AIS and E-Navigation channels as additional channels requiring protection from channel interleaving. MOD USA/AI 1.10/5 n) The use of these channels (75 and 76) should be restricted to navigation-related communications only and all precautions should be taken to avoid harmful interference to channel 16, e.g. by limiting the output power to 1 W or by means of geographical separation. These channels are also used for long range detection of AIS in accordance with recommendation ITU-R M.1371. Reasons: Proposed change protects the channels intended to be used for long-range detection of AIS from harmful interference. 31 ADD USA/AI 1.10/6 r) When using these channels (27 and 28), all precautions should be taken to avoid harmful interference to AIS 1 and AIS 2.

NTIA proposes no change for some of the candidate frequency bands for potential mobile-satellite services allocations. NTIA considered the Federal agencies’ input toward the development of U.S. proposals for WRC-12. NTIA forwards this package for consideration and review by your WRC-12 Advisory Committee. Dr. Darlene Drazenovich is the primary contact from my staff. Sincerely, (Original Signed July 13, 2010) Karl B. Nebbia Associate Administrator Office of Spectrum Management 33 UNITED STATES OF AMERICA DRAFT PROPOSALS FOR THE WORK OF THE CONFERENCE Agenda Item 1.25: to consider possible additional allocations to the mobile-satellite service, in accordance with Resolution 231 (WRC-07) Background Information: WRC-12 will consider possible allocations to the mobile-satellite service (MSS), particularly in the 4-16 GHz range, based on the results of ITU-R sharing and compatibility studies and without placing undue constraints on the existing services. The ITU-R studies to date on some of the possible bands indicate difficulties in sharing with existing services. For other possible bands, the ITU-R did not conduct studies. Therefore, this proposal advocates no change in the spectrum allocations listed below due to the results of the ITU-R sharing studies. 5 150 – 5 250 MHz Band Some administrations are considering the band 5 150-5 250 MHz for MSS downlinks. This band is allocated to the aeronautical radionavigation service (ARNS), the fixed-satellite service (FSS) (Earth-to- space) and the mobile (except aeronautical mobile) service on a primary basis. This band is also allocated to the aeronautical mobile service on a primary basis in some countries through No. 5.446C. The ITU-R has not conducted studies between the MSS and ARNS. The ITU-R identified this ARNS allocation as a candidate band for UAS sense and avoid (S&A) applications. The ITU-R conducted studies between the MSS (geostationary orbit (GSO) spacecraft utilizing multi-beam downlink antennas) and FSS (feeder uplinks to non-GSO MSS systems). The ITU-R studies do not fully quantify the constraints necessary on the proposed MSS downlinks to avoid interference to the FSS (MSS Feeder uplinks) space station receiver, especially if the MSS system uses non-GSO satellites. Radio local area network (RLAN) systems operate in this band, limited to indoor use and power constraints through Resolution 229 (WRC-03). The MSS Earth Stations (MESs) may receive interference from the RLANs in certain circumstances. 7 055 – 7 250 MHz Band Some administrations are considering the band 7 055 – 7 250 MHz for MSS downlinks. The entire band is allocated to the fixed and mobile services. The ITU-R conducted limited studies between the MSS (GSO) and fixed service (FS) indicating sharing difficulties. Studies of non-GSO MSS systems may produce similar results. Systems in the FS between 7125 – 7250 MHz operate point-to-point microwave data communication links for backbone networks to transport voice, video, and data traffic to support various missions, including air traffic control information. These links are critical for control of aircraft during all phases of flight and under all weather conditions. The point-to-point microwave communication links also interconnect multiple local vessel traffic systems (VTS) radar and radio communications sites important for marine traffic in enclosed waterways. The sub-band 7 145 – 7 235 MHz band is allocated to the space research service (SRS) (Earth-to-space). ITU-R studies have shown a strong potential for interference into the SRS space stations from MSS satellites unless extraordinary mitigation techniques are applied. Large exclusion zones are needed around SRS earth stations to prevent interference with MESs. 34 8 400 – 8 500 MHz Band Some administrations are considering the band 8 400 – 8 500 MHz for MSS uplinks. This band is allocated to the fixed, mobile, and space research (space-to-Earth) services. The 8 400 – 8 450 MHz sub-band is used for SRS deep space applications. Large exclusion zones (several hundred km over land, longer over water) are needed around SRS earth stations to prevent interference from MESs. The required separation distances would make large areas unavailable for MSS use, despite the relatively low number of SRS earth stations. The MSS satellites could be subject to excessive interference during SRS mission phases when the SRS spacecraft is in the near-Earth environment. In conjunction with the frequency band 7125 – 7250 MHz, systems operating in this band perform point- to-point microwave data communications links for backbone networks to transport voice, video, and data traffic to support various missions, including air traffic control information. These links are critical for control of aircraft during all phases of flight and under all weather conditions. The point-to-point microwave communications links also interconnect multiple local VTS radar and radio communications sites important for marine traffic in enclosed waterways. The ITU-R has conducted limited studies between the MSS and FS, which indicate sharing difficulties. As with the 7 055 – 7 250 MHz band, the ITU-R only conducted studies in the 8 400 – 8 500 MHz band for GSO MSS systems and it is likely that studies of non-GSO systems will produce less favorable results. 10.5 – 10.6 GHz Band Some administrations are considering the band 10.5-10.6 GHz for MSS downlinks. The band is allocated to the fixed and mobile services. In the sub-band 10.5-10.55 GHz, the band is allocated to the radiolocation service on a secondary basis in Region 1 and on a primary basis in Regions 2 and 3. In the sub-band 10.55-10.6 GHz, radiolocation is secondary. The ITU-R has not conducted studies between the MSS and radiolocation. 13.25 – 13.4 GHz Band Some administrations are considering the band 13.25 – 13.4 GHz for MSS downlinks. The band is allocated to the Earth exploration-satellite service (EESS) (active) and space research service (SRS) (active) on a primary basis. The band is also allocated to the aeronautical radionavigation service on a primary basis, limited to use for Doppler navigation aids through No. 5.497. Airborne Doppler navigation systems installed in aircraft for this band (helicopters as well as certain airplanes) perform specialized applications such as continuous determination of ground speed and drift angle information of an aircraft with respect to the ground. The Radio Technical Commission for Aeronautics (RTCA) has developed a standard for this equipment: DO-158 - Minimum Operational Performance Standards (MOPS) – Airborne Doppler Radar Navigation Equipment. ITU-R studies did not evaluate the effects of the MSS on the EESS and SRS, to include the three types of EESS (active) instruments: scatterometers, altimeters and precipitation radars. MESs will also be susceptible to interference from the EESS (active) and SRS (active) space stations. The ITU-R has not conducted studies between the MSS and the Doppler radars. The ITU-R has also identified this band for potential UAS S&A applications under agenda item 1.3. 35 15.43 – 15.63 GHz Band Some administrations are considering the 15.43-15.63 GHz band for MSS uplinks. The band is allocated to FSS (Earth-to-space), limited to feederlinks for non-GSO MSS systems through No. 5.511A. The band is also allocated to ARNS and provision No. 4.10 of the RR applies. ITU-R studies show co-coverage sharing between the MSS and aircraft landing systems (ALS) and aircraft multipurpose radars (MPR) will be difficult. There is no evidence of FSS use of this band. WRC-12 agenda item 1.21 considers an allocation in the 15.4-15.7 GHz band to the radiolocation service. Preliminary ITU-R studies between MSS and radiolocation indicate a single MES will cause interference into the radar, with additional MESs causing more interference. WRC-12 agenda item 1.3 considers a portion of the 15.4-15.7 GHz band for UAS S&A applications in the existing ARNS allocation or UAS command applications in a new aeronautical mobile-satellite (route) service allocation.

NTIA proposes to modify Nos. 11.41 and 11.43C. NTIA considered the Federal agencies’ input toward the development of U.S. proposals for WRC-12. NTIA forwards this package for consideration and review by your WRC-12 Advisory Committee. Dr. Darlene Drazenovich is the primary contact from my staff. Sincerely, (Original Signed July 14, 2010) Karl B. Nebbia Associate Administrator Office of Spectrum Management 39 UNTIED STATES OF AMERICA DRAFT PROPOSALS FOR THE WORK OF THE CONFERENCE 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) Background Information: The Working Party of the Special Committee on Regulatory and Procedural Matters (SC-WP) is considering the application of Nos. 11.41 and 11.42, in particular, the case of an interference complaint received within the four month period indicated in No. 11.41. The BR’s initial proposal suggested that: “[i]f the interference is not eliminated by the end of the four-month period envisaged for simultaneous operation, the Bureau cancels the “incoming” assignment (i.e. the one recorded under No. 11.41) and informs the concerned administration accordingly.” The BR proposal provides excessive control to the administration claiming interference, since there is no requirement to present proof of harmful interference. In the case of actual harmful interference, it may take considerable time to establish the source of interference potentially resulting in automatic cancellation in case of unresolved complaints under the BR and SC-WP proposal. The SC-WP also considered complaints of interference received after the four-month period. The BR’s initial proposal suggested that: “For complaint received beyond the four month period indicated in No. 11.41, it requests the administration responsible for the “incoming” assignment (i.e. the one recorded under No. 11.41) to eliminate the harmful interference immediately under No. 11.42. The matter is thereafter dealt with in accordance with the procedures set forth in Article 15 of the Radio Regulations.” In summary, if an interference complaint is received against a new assignment within the first four months of a new assignment and the interference is not eliminated, the BR will cancel the new assignment. If an interference complaint is received after the first four months, the BR will ask the new assignee to eliminate the interference immediately and Article 15 applies. Also, the BR addressed definitive and provisional recordings of frequency assignments and related articles of the Radio Regulations. An assignment receiving an unfavorable finding for not completing coordination and filing under No.11.41 is considered as “provisional.” If no interference has occurred between the provisional assignment and any assignment for which was the basis for the unfavorable finding during the four month period, then the provisional is changed to “definitive.” An assignment recorded under No. 11.41, even if the status changes from provisional to definitive, is still considered by the BR at a lower status to the assignment for which the unfavorable finding was based under No.11.32A. There should be no difference in treatment applied to situations where the interference complaints occur within or outside the four-month period. Therefore, an assignment recorded under No. 11.41 should be equal to the status of the existing assignment which was the basis for the unfavorable findings under No.11.32A if coordination with the latter is completed and should not be seen as “always lower.” This could be a disincentive to complete coordination. 40 This proposal modifies Article 11 of the Radio Regulations to clarify that interference complaints related to Nos. 11.41 and 11.42 should be treated equally following the provisions of Article 15. The status of an assignment initially recorded under No. 11.41 should be equal to the status of the existing assignment which was the basis for the unfavorable findings under No. 11.32A if coordination is later completed with respect to that existing assignment. Proposals: ARTICLE 11 Notification and recording of frequency assignments 1, 2, 3, 4, 5, 6, 7 (WRC-07) Section II – Examination of notices and recording of frequency assignments in the Master Register MOD USA/7/1 11.42 Should harmful interference be caused by an assignment recorded either provisionally or definitively under No. 11.41 to any recorded assignment which was the basis of the unfavourable finding, the station using the frequency assignment recorded under No. 11.41 shall, upon receipt of advice thereof under the provisions of Article 15, immediately eliminate this harmful interference. Reasons: To clarify that the harmful interference situations addressed in No.11.42 should be addressed treated equally following the provisions of Article 15 instead of using a specific procedure applicable only to such situations. MOD USA/7/2 11.43C Where the notifying administration resubmits the notice and the Bureau finds that the coordination procedures specified in No. 11.32 have been successfully completed with all administrations whose space or terrestrial radiocommunication stations may be affected, the assignment shall be recorded in the Master Register. The date of receipt by the Bureau of the original notice shall be entered in the appropriate column of the Master Register. The date of receipt by the Bureau of the resubmitted notice shall be entered in the “Remarks” column and any conditions related to initial recording under No. 11.41 shall be removed. Reasons: To ensure the status of an assignment initially recorded under No. 11.41 is equal to the status of the existing assignment which was the basis for the unfavourable findings under No. 11.32A if coordination is later completed with respect to that existing assignment. _____________________
