1 ATTACHMENT 2 to FCC Public Notice DA 14-88 Draft Proposals formulated and approved within the National Telecommunications and Information Administration: 2 WAC/057(27.01.14) Ms. Mindel De La Torre Chief of the International Bureau Federal Communications Commission 445 12th 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 the draft Executive Branch proposal for WRC-15 agenda item 1.1. NTIA proposes no change to the 2025-2110 and 2200-2290 MHz bands. NTIA considered the federal agencies’ input toward the development of U.S. proposals for WRC-15. NTIA forwards this package for your consideration and review by your WRC-15 Advisory Committee. Dr. Darlene Drazenovich is the primary contact from my staff.

Nebbia Associate Administrator Office of Spectrum Management 3 UNITED STATES OF AMERICA DRAFT PROPOSALS FOR THE WORK OF THE CONFERENCE Agenda Item 1.1: to consider additional spectrum allocations to the mobile service on a primary basis and identification of additional frequency bands for International Mobile Telecommunications (IMT) and related regulatory provisions, to facilitate the development of terrestrial mobile broadband applications, in accordance with Resolution 233 (WRC-12) Background Information: The 2012 World Radiocommunication Conference (WRC-12) recognized a need for additional radio spectrum to support the increasing mobile data traffic, and placed consideration of additional spectrum allocations for terrestrial mobile broadband applications on the agenda for WRC-15. CPM-15/1 tasked Working Party 5D (WP5D) to provide frequency ranges to Joint Task Group 4-5-6-7 (JTG) that would be suitable for IMT operations. WP5D included the ranges 2 025- 2 110 MHz and 2 200-2 290 MHz among the many frequency ranges below 6 GHz provided to the JTG. WRC-12 resolved to invite the ITU-R to carry out sharing and compatibility studies between IMT systems and systems of services already having allocations in potential candidate bands and in adjacent bands, as appropriate, taking into account the current and planned use of these bands by the existing services. CPM-15/1 tasked the JTG with carrying out the studies. Studies submitted to the JTG that assessed the feasibility for accommodation of IMT long-term evolution (LTE) systems in both the 2 025-2 110 MHz and 2 200-2 290 MHz frequency ranges have shown that sharing is not feasible with existing services in these frequency ranges. These studies reaffirmed earlier ITU studies that resulted in the adoption of No. 5.391 at WRC-97, which prohibits high-density mobile systems from operation within these frequency bands. The United States proposes no change to the frequency bands 2 025-2 110 MHz and 2 200-2 290 MHz. 4 Proposals: NOC USA/1.1/1 ARTICLE 5 Frequency allocations Section IV – Table of Frequency Allocations (See No. 2.1) 1 710-2 170 MHz Reasons: ITU-R studies have shown that sharing is not feasible between International Mobile Telecommunications (IMT) systems and systems of incumbent services in the 2 025-2 110 MHz band.

NTIA proposes no change to the table of allocations for agenda item 1.1 and 1.9.2. For agenda item 1.14, NTIA proposes a modification to Article 1 definition for Coordinated Universal Time and a consequential change to Article 2. Finally, NTIA proposes a future conference agenda item addressing Earth exploration-satellite service allocations at 460-470 MHz. NTIA considered the federal agencies’ input toward the development of U.S. proposals for WRC-15. NTIA forwards this package for your consideration and review by your WRC-15 Advisory Committee. Dr. Darlene Drazenovich is the primary contact from my staff. Sincerely, (Original Signed December 13, 2013) Karl B. Nebbia Associate Administrator Office of Spectrum Management 7 UNITED STATES OF AMERICA DRAFT PROPOSALS FOR THE WORK OF THE CONFERENCE Agenda Item 1.1: to consider additional spectrum allocations to the mobile service on a primary basis and identification of additional frequency bands for International Mobile Telecommunications (IMT) and related regulatory provisions, to facilitate the development of terrestrial mobile broadband applications, in accordance with Resolution 233 (WRC-12) Background Information: The ITU-R is considering the band 1 435-1 525 MHz as a potential candidate for a new mobile service allocation under the 2015 World Radiocommunication Conference agenda item 1.1. Some administrations utilize the band 1 435-1 525 MHz for flight- testing in the Americas. The band is critical for aerospace research and development, and aircraft safety standards certification. Flight testing requires real-time data for the protection of the pilot and aircrew, test aircraft, and people and property on the ground. Administrations performing such flight testing require transmission of this data in interference-free frequency bands to minimize the chance of disruption to critical safety communications. Thus, the use of the band 1 435-1 525 MHz for aeronautical mobile telemetry (AMT) systems is essential for the aerospace manufacturing industry in the Americas. No. 5.343 provides that “[i]n Region 2, the use of the band 1 435-1 525 MHz by the aeronautical mobile service for telemetry has priority over other uses by the mobile service.” ITU-R compatibility studies show that co-frequency sharing of IMT with AMT systems in Region 2, in the absence of very large exclusion zones, is not practical. This result is consistent with a study performed independently for Region 1 by another administration. The two studies independently arrive at comparable, very large protection distances (e.g. over 100 km in the case of IMT to AMT interference, and over 365 km in the case of AMT to IMT interference). Therefore, Region 2 requires no change to the table of allocations. 8 Proposal: NOC USA/1.1/1 ARTICLE 5 Frequency allocations 1 300-1 525 MHz Allocation to Services Region 1 Region 2 Region 3 … 1 429-1 452 FIXED MOBILE 5.343 5.338A 5.341 … 1 452-1 492 FIXED MOBILE 5.343 BROADCASTING BROADCASTING-SATELLITE 5.208B 5.341 5.344 5.345 … 1 492-1 518 FIXED MOBILE 5.343 5.341 5.344 ... … 1 518-1 525 FIXED MOBILE 5.343 MOBILE-SATELLITE (space-to-Earth) 5.348 5.348A 5.348B 5.351A 5.341 5.344 ... 9 Reasons: Based on studies submitted in ITU-R, co-frequency sharing between IMT and AMT is not practical. Due to the need for continued use of AMT within Region 2, the band 1435-1525 MHz should not be identified for IMT use in Region 2. 10 UNITED STATES OF AMERICA DRAFT PROPOSALS FOR THE WORK OF THE CONFERENCE Agenda Item 1.9.2: to consider, in accordance with Resolution 758 (WRC-12) … the possibility of allocating the bands 7 375-7 750 MHz and 8 025-8 400 MHz to the maritime-mobile satellite service and additional regulatory measures, depending on the results of appropriate studies Background Information: WRC-15 agenda item 1.9.2 directs consideration of allocating the bands 7 375-7 750 MHz and 8 025-8 400 MHz to the maritime mobile-satellite service (MMSS). The proposed allocation would effectively allow the entire 7 250-7 750 MHz (space-to-Earth) and 7 900-8 400 MHz (Earth-to-space) bands (subject to No. 9.21 agreement for bands 7 250-7 375 MHz and 7 900-8 025 MHz) to be accessible to the MMSS, making it identical to the existing fixed-satellite service (FSS) allocations. The Earth exploration-satellite service (EESS) (space-to-Earth) has a worldwide primary allocation in the band 8 025-8 400 MHz. This band supports the downlink of environmental and climate data from non-geostationary orbit (NGSO) satellites, which are often in polar orbits, to earth stations that may be located at high latitudes and/or near coastal areas. The space research service (SRS) (space-to-Earth) has a worldwide primary allocation in the adjacent band 8 400-8 500 MHz, with No. 5.465 limiting the band 8 400-8 450 MHz to deep space use. There is extensive use of the band 8 400-8 450 MHz at sites around the world, including in coastal locations, by the SRS (space-to-Earth) for deep space with very large antennas and sensitive receivers that are susceptible to possible interference from out-of-band emissions. ITU-R sharing studies demonstrate that the proposed MMSS uplinks in the 8 025-8 400 MHz bands will interfere with existing services in the band, specifically the EESS (space-to-Earth). The proposed satellite uplink transmissions will cause interference into EESS earth station receivers. Very large separation distances from shore required to mitigate this interference would make the use of MMSS impractical. ITU-R sharing studies demonstrate that the proposed MMSS uplinks in the 8 025-8 400 MHz bands will also interfere with the adjacent SRS (space- to-Earth) allocation in 8 400-8 500 MHz, specifically the 8 400-8 450 MHz sub-band limited to deep space research. Large separation distances and/or frequency separation would be required to mitigate interference. 11 Proposal: NOC USA/AI 1.9.2/1 ARTICLE 5 Frequency allocations Reasons: ITU-R studies indicate a potential for interference into existing services, both in-band and adjacent band. SUP USA/AI 1.9.2/2 RESOLUTION 758 (WRC-12) Allocation to the fixed-satellite service and the maritime- mobile satellite service in the 7/8 GHz range Reasons: This proposal is consequential to completion of the agenda item 1.9.2. This proposal does not reflect a position on studies under this Resolution for agenda item 1.9.1. 12 UNITED STATES OF AMERICA DRAFT PROPOSALS FOR THE WORK OF THE CONFERENCE Agenda Item 1.14: to consider the feasibility of achieving a continuous reference time-scale, whether by the modification of coordinated universal time (UTC) or some other method, and take appropriate action, in accordance with Resolution 653 (WRC-12) Background Information: Coordinated Universal Time (UTC) is the international standard time scale for practical timekeeping in the modern world. The basic unit of measurement is the internationally accepted Système International (SI) second, which is realized in practice by atomic clocks in national laboratories throughout the world. The Bureau International des Poids et Mesures uses clock information from these laboratories to coordinate the various national realizations of UTC. This process provides time with a stability of better than a billionth of a second per day for the international infrastructure that requires accurate timing information, such as communications, computer networks, navigation, and air traffic control. The Radio Regulations define UTC in No. 1.14 through incorporation by reference of Recommendation ITU-R TF.460-6. The International Radio Consultative Committee (CCIR) formally adopted the system for UTC in Recommendation 374 in 1963. The CCIR introduced leap seconds into the definition of UTC beginning on January 1, 1972. In its Recommendation 460, the CCIR stated that UTC is a timescale that uses the SI second. The CCIR also stated the accounting of those seconds will be adjusted, when necessary, in 1 second steps to compensate for the slowing of the Earth’s rotation rate. This version of the UTC system remains in use today, defined by ITU-R (formerly CCIR) Recommendation ITU-R TF.460-6. Since their introduction, leap seconds have been inserted into UTC at irregular intervals because the slowing of the Earth’s rotation rate is not uniform. Much of our international infrastructure relies on steady, accurate timing. Many of these systems view leap seconds as disruptions of the count in the time stream. Resolution 653 (WRC-12), considering e, states “that the occasional insertion of leap seconds into UTC may create difficulties for systems and applications that depend on accurate timing.” Given that our reliance on many of these systems and applications is both critical and growing with time, WRC-12 adopted agenda item 1.14 in order to consider the feasibility of achieving a continuous reference time-scale, whether by the modification of UTC or some other method. Given the results of studies, this proposal supports the adoption of UTC without leap seconds as the most feasible means for achieving a continuous reference time-scale for dissemination by radiocommunication systems. To ensure sufficient time for legacy systems to update hardware and/or software to accommodate the elimination of leap seconds from UTC, a period of five years from the date of entry into force of the Final Acts of WRC-15 will be the effective date of application of revisions to the Radio Regulations resulting from Resolution 653 (WRC-12). 13 Proposal: ARTICLE 1 Terms and definitions MOD USA/AI 1.14/1 Section I – General terms 1.14 Coordinated Universal Time (UTC): Time scale, based on the second (SI) and maintained by the Bureau International de Poids et Mesures (BIPM), that forms the basis for the coordinated dissemination of standard frequencies and time signals., as defined in Recommendation ITU-R TF.460-6. (WRC-03) For most practical purposes associated with the Radio Regulations, UTC is equivalent to mean solar time at the prime meridian (0° longitude), formerly expressed in GMT. Reasons: The modification removes the incorporation by reference of Recommendation ITU-R TF.460- 6, which defines the use of leap seconds in UTC. The modification also adds a reference to the international organization responsible for the maintenance of the UTC time scale. Finally, because UTC will no longer be tied to Earth’s rotation, the modification removes the equivalence between UTC and the mean solar time at the prime meridian. ARTICLE 2 Nomenclature Section II – Dates and times MOD USA/AI 1.14/2 2.5 Whenever a date is used in connection with Coordinated Universal Time (UTC), this date shall be that of the prime meridian, at the appropriate time taking into account the difference between UTC and the mean solar time of the prime meridian, the prime meridian corresponding to zero degrees geographical longitude. Reasons: Consequential change resulting from removing the equivalence between UTC and the mean solar time at the prime meridian in the definition of UTC. 14 MOD USA/AI 1.14/3 CHAPTER X Provisions for entry into force of the Radio Regulations (WRC-152) Reasons: To update the WRC where provisions for entry into force will be recorded for the final acts of the conference.

Additional provisions and abrogation for WRC-15 may be added to Resolution [USA/114/AAA]. SUP USA/AI 1.14/9 RESOLUTION 653 (WRC-12) Future of the Coordinated Universal Time time-scale Reasons: The required studies have been completed and this resolution is no longer needed. 17 UNITED STATES OF AMERICA DRAFT PROPOSALS FOR THE WORK OF THE CONFERENCE Agenda Item 10: 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: The 460-470 MHz band is allocated on a primary basis to the fixed and mobile services. The meteorological-satellite service currently has a secondary allocation in this band. Within this band, the Argos Data Collection System (ADCS) is used to monitor over 21,000 individual platforms around the globe for 1,900 operators in 118 countries. Critical applications of the ADCS include atmospheric & ocean monitoring/research, tropical cyclone forecasting, fishery management, oil spill tracking, fishing vessel tracking, search & rescue modeling (at sea), anti-piracy alerting, import/export & hazardous materials tracking, endangered species studies, migration mapping, and wildlife tracking and management. RF Central Station Alarm (CSA) systems operate on the same frequency as the ADCS downlink. Due to the potential for interference to the CSA systems, the operator turned off the ADCS on the NOAA-19 satellite. To provide additional protection to existing services in the band, the next generation of ADCS transmitters will implement a direct sequence spread spectrum in the satellite downlink to reduce the power flux density (pfd) in the 460-470 MHz band to flux < - 152 dBW/m2/4kHz. To protect the recent significant investment and expansion of the ADCS systems, this proposal advocates studying sharing between the existing meteorological-satellite (space-to-Earth) service and incumbent services in the 460-470 MHz band with a view to upgrading the meteorological- satellite service to primary and potentially adopting a pfd limit on the meteorological-satellite (space-to-Earth) service to protect the incumbent services. A co-primary allocation status would protect the ADCS from any new services entering the band. Proposal: MOD USA/10/1 RESOLUTION 806 (WRC-15) Agenda for the 2018 World Radiocommunication Conference The World Radiocommunication Conference (Geneva, 2015), 18 ADD USA/10/2 X.X to review the allocations to the meteorological-satellite service in the 460-470 MHz band with a view to upgrading service to a primary allocation. Reasons: To allow meteorological-satellite service to operate on a co-primary status with fixed and mobile. ADD USA/10/3 RESOLUTION AAA (WRC-15) Primary Allocation to the Meteorological Satellite Service in the 460 – 470 MHz Band The World Radiocommunication Conference (Geneva, 2015), considering a) that the Argos Data Collection System (ADCS) is used to monitor over 21,000 individual platforms around the globe for 1,900 operators in 118 countries; b) that the use of ADCS can provide spectrum efficiency by interrogating collection platforms prior to their transmission; c) that ADCS may be authorized to operate on a secondary basis with respect to the fixed and mobile services, recognizing a) that technology has been developed to provide more efficient use of the spectrum; b) that a digital spread spectrum scheme will be used to increase mitigation of potential interference to incumbents in the band; c) that the satellite-to-platform down-link at 465.9875 MHz significantly improves platform and system performance, including data latency and battery life; d) that due to the significant investment and expansion of ADCS, future conflicts or interference issues must be avoided, resolves that taking into account the results of ITU-R studies, WRC-18 consider upgrading the current secondary allocation of the meteorological-satellite service (space-to-Earth) to primary in the 460-470 MHz band, resolves to invite the ITU-R 1. to conduct in time for WRC-18, sharing studies between the meteorological-satellite service (space-to-Earth) and the fixed and mobile services in the band 460-470 MHz; 2 to complete the studies, taking into account the present use of the allocated band; 19 3 to determine the appropriate power flux density limit to be placed on the meteoroglical-satellite service (space-to-Earth) to protect the existing services in the band, invites administrations to participate actively in the studies and provide the technical and operational characteristics of the systems involved by submitting contributions to the ITU-R, instructs the Secretary General to bring this resolution to the attention of the Space Frequency Coordination Group (SFCG) and other international and regional organizations concerned. Reasons: A resolution will support the ITU-R studies needed under the relevant WRC-18 agenda item. 20 ATTACHMENT PROPOSAL FOR ADDITIONAL AGENDA ITEM STUDYING THE ALLOCATION OF THE METEOROLOGICAL-SATELLITE SERVICE IN THE 460-470 MHZ BAND Subject: Proposed Future WRC Agenda Item for WRC-2018 studying meteorological-satellite service in the 460-470 MHz band Origin: United States of America Proposal: To review the services in the 460-470 MHz band with a view to upgrading the meteorological satellite service to primary status.

Nebbia Associate Administrator Office of Spectrum Management 22 UNITED STATES OF AMERICA DRAFT PROPOSALS FOR THE WORK OF THE CONFERENCE Agenda Item 1.12: to consider an extension of the current worldwide allocation to the Earth exploration-satellite (active) service in the frequency band 9 300 – 9 900 MHz by up to 600 MHz within the frequency bands 8 700 – 9 300 MHz and/or 9 900 – 10 500 MHz, in accordance with Resolution 651 (WRC-12) Background Information: This agenda item considers extending the current Earth exploration- satellite service (EESS) (active) allocation in the range 9 300 – 9 900 MHz by an additional 600 MHz within portions of the range 8 700 – 10 500 MHz. Incumbent services in the 9 900 – 10 500 MHz range include the radiolocation, fixed, mobile, amateur, and amateur-satellite services. The radiolocation service is primary worldwide throughout the band. The fixed service is secondary worldwide from 9 900 – 10 000 MHz. The fixed and mobile services are primary in ITU Regions 1 and 3 from 10 000 – 10 450 MHz. The amateur service is secondary at 10 000 – 10 500 MHz worldwide, and the amateur-satellite service is secondary at 10 450 – 10 500 MHz worldwide. Currently, the 9 000 – 9 300 MHz range contains primary allocations to aeronautical and maritime radionavigation safety services. It is imperative to protect these safety service operations from harmful interference. There is potential interference to stations operating in the adjacent 10.5 – 10.7 GHz frequency range if the extension is made in the upper 9 900 – 10 500 MHz range, including stations in passive services (radio astronomy, Earth exploration- satellite (passive), and space research (passive). Similarly, there is potential interference to stations operating in the space research service in the band 8 400 – 8 500 MHz if the EESS allocation is extended to the lower 8 700 – 9 300 MHz frequency range. In accordance with Resolution 651 (WRC-12), the ITU conducted sharing studies to ensure the protection of existing in-band services and compatibility studies to address interference due to unwanted emissions into the services in the 10 600 – 10 700 MHz frequency range and the space research service in the 8 400 – 8 500 MHz band. Studies have demonstrated that sharing is possible between EESS (active) and the existing services in the 9 900 – 10 500 MHz frequency range and that passive services in the 10 600 – 10 700 MHz frequency range can be protected from unwanted emissions from a new EESS (active) allocation. Given the results of sharing studies, this proposal supports an allocation of an additional 600 MHz to the EESS (active) as a primary allocation in the frequency range 9 900 – 10 500 MHz. This proposal extends the protections for incumbent services in No. 5.476A to the new frequency allocations and indicates that the use of this frequency allocation extension may be limited to systems requiring a necessary bandwidth of 1 200 MHz that cannot be fully accommodated within the 9 300 – 9 900 MHz band, pending the results of ITU-R studies. This proposal supports no change to allocations in the 8 700 – 9 300 MHz frequency range because ITU-R studies show feasibility to make the entire 600 MHz extension to the EESS (active) in frequencies above the existing EESS (active) allocation 9 300 – 9 900 MHz. 23 Proposal: ARTICLE 5 Frequency allocations Section IV – Table of Frequency Allocations (See No. 2.1) MOD USA/AI 1.12/1 9 500-10 000 MHz Reasons: Studies have shown that sharing between the EESS (active) and other services in the frequency range of 9 900 – 10 500 MHz is feasible.

NTIA proposes no change to the table of allocations. NTIA considered the federal agencies’ input toward the development of U.S. proposals for WRC-15. NTIA forwards this package for your consideration and review by your WRC-15 Advisory Committee. Dr. Darlene Drazenovich is the primary contact from my staff. Sincerely, (Original Signed January 6, 2014) Karl B. Nebbia Associate Administrator Office of Spectrum Management 27 UNITED STATES OF AMERICA DRAFT PROPOSALS FOR THE WORK OF THE CONFERENCE Agenda Item 1.6.1: to consider possible additional primary allocations, to the fixed-satellite service (Earth-to-space and space-to-Earth) of 250 MHz in the range between 10 GHz and 17 GHz in Region 1; and review the regulatory provisions on the current allocations to the fixed- satellite service (FSS) within each range, taking into account the results of ITU-R studies, in accordance with Resolutions 151 (WRC-12) Background Information: The 14.5-15.35 GHz frequency range has allocations to the fixed and mobile radio services on a primary basis in all three ITU regions. The frequency band 14.5- 14.8 GHz also has an allocation to fixed-satellite service (FSS) on a primary basis in all three ITU regions subject to Radio Regulation No. 5.510. No. 5.510 limits FSS use to feeder links for the broadcasting satellite service outside Europe, which are subject to the Appendix 30A Broadcast Satellite Plan and associated procedures. The space research service has an allocation on a secondary basis in the frequency band 14.5-15.35 GHz in all three regions. Aeronautical mobile data links currently operate in the 14.5-15.35 GHz band under the mobile service (MS) allocation, the parent service to aeronautical mobile service (AMS). The band 15.4 – 17.0 GHz has allocations to the radiolocation service (RLS) on a primary basis in all three Regions and to the aeronautical radionavigation service on a primary basis in all three Regions. Some Administrations will operate airborne synthetic aperture radars worldwide as part of the global RLS allocation in the band 15.4-17 GHz. Some Administrations also operate an airport surface detection system on a co-primary basis with the primary RLS in the band 15.7- 16.2 GHz. ITU-R sharing studies demonstrate that the proposed FSS (Earth-to-space) links in the 10.0-17.0 GHz bands will interfere with existing authorized services in the bands 14.5-15.35 GHz and 15.4-17.0 GHz. The sharing studies’ results show that in order to protect the AMS receivers operating in the band 14.5-15.35 GHz band, there is a required separation distance of up to 577 km (not accounting for terrain obstruction). The studies also show that in order to protect radiolocation stations operating in the band 15.4-17.0 GHz, a separation distance of up to 420 km (not accounting for terrain obstruction) is required. Given the large, required separation distances around AMS and RLS receivers’ operational area and the mobile nature of AMS/RLS airborne receiver, the ubiquitous deployment of FSS transmitters would make mitigation and coordination approaches to permit sharing with the FSS very difficult or impractical. In addition, FSS space station receivers in the geostationary satellite orbit may be subject to unacceptable levels of interference from existing operations in these bands. With respect to FSS downlinks from Region 1 FSS satellites, ITU-R studies indicate radiolocation stations in Region 2 may receive unacceptable levels of interference from FSS space stations in the geostationary satellite orbit and FSS downlink earth stations may receive unacceptable levels of interference from airborne stations beyond the radio horizon. Mitigation techniques sufficient to protect the systems operating in the current allocations may impose severe if not impractical restrictions on new FSS systems that might operate in this band. 28 Proposal: ARTICLE 5 Frequency allocations Section IV – Table of Frequency Allocations (See No. 2.1) NOC USA/AI 1.6.1/1 14-15.4 GHz Reasons: ITU-R studies indicate a potential for interference into existing MS and AMS systems.
