ATTACHMENT B to FCC Public Notice DA 18-1017 Draft Proposals formulated and approved within the National Telecommunications and Information Administration: DOCUMENT WAC/061 (16.08.18) Mr. Tom Sullivan Chief, International Bureau Federal Communications Commission 445 12th Street, SW Washington, DC 20554 Dear Mr. Sullivan: The National Telecommunications and Information Administration (NTIA), on behalf of the Executive Branch agencies, approves the release of the enclosed proposals for the 2019 World Radiocommunication Conference (WRC-19) which address: 1) Agenda Item 1.16 – Radio Local Area Networks studies at 5 150-5 925 MHz; 2) Agenda Item 9, Issue 9.1.5 - Incorporation of Recommendations M.1638-1 & M.1849-1 in Nos. 5.447F & 5.450A by reference; and 3) Agenda Item 10 – Earth Exploration-Satellite Service allocation in the frequency range 40-50 MHz. NTIA considered the federal agencies’ input toward the development of these U.S. proposals for WRC-19. NTIA forwards this package for your consideration and review. If you have any questions, please contact Mr. Charles Glass, our WRC Coordinator, who can be reached at (202) 482-1896 or cglass@ntia.doc.gov. Sincerely, Peter A. Tenhula Acting Associate Administrator Office of Spectrum Management Enclosures (3) WAC/062 (06.09.18) UNITED STATES OF AMERICA PROPOSALS FOR THE WORK OF THE CONFERENCE Agenda Item 1.16: To consider issues related to wireless access systems, including radio local area networks (WAS/RLAN), in the frequency bands between 5 150 MHz and 5 925 MHz, and take the appropriate regulatory actions, including additional spectrum allocations to the mobile service, in accordance with Resolution 239 (WRC-15). Background Information: Resolution 239 (WRC15) calls for ITU-R to study WAS/RLAN technical characteristics and operational requirements in the 5 GHz frequency range. The resolution also calls for ITU-R to perform sharing and compatibility studies between WAS/RLAN applications and incumbent services in these frequency bands: · 5 150-5 350 MHz · 5 350-5 470 MHz · 5 7255 850 MHz · 5 850-5 925 MHz The studies are to be performed to: 1) ensure the protection of incumbent services, including their current and planned use; 2) consider enabling outdoor WAS/RLAN operations in the band 5 150-5 350 MHz; 3) potentially add mobile service allocations to accommodate WAS/RLAN operations in the 5 350-5 470 MHz and 5 725-5 850 MHz bands; and 4) identify potential WAS/RLAN use in the 5 850-5 925 MHz band. This document proposes NOC for the 5 250-5 350 MHz, 5 350-5 470 MHz, 5 725-5 850 MHz, and 5 850-5 925 MHz bands. Proposal: Article 5 Frequency Allocations Section IV – Table of Frequency Allocations (See No. 2.1) NOC USA/1.16/1 5 250-5 570 MHz Allocation to services Region 1 Region 2 Region 3 5 250-5 255 EARTH EXPLORATION-SATELLITE (active) MOBILE except aeronautical mobile 5.446A 5.447F RADIOLOCATION SPACE RESEARCH 5.447D 5.447E 5.448 5.448A 5 255-5 350 EARTH EXPLORATION-SATELLITE (active) MOBILE except aeronautical mobile 5.446A 5.447F RADIOLOCATION SPACE RESEARCH (active) 5.447E 5.448 5.448A … Reasons: Since the adoption of Resolution 229 (Rev. WRC-12) at WRC-03, millions of WAS/RLAN (such as Wi-Fi) devices have been deployed in the band 5 250-5 350 MHz. Studies in response to invite c of Resolution 229 have shown that changing the WAS/RLAN operating conditions in the band 5 250-5 350 MHz would not ensure protection of incumbent radiodetermination services and EESS (active) sensors. Furthermore, the studies confirmed that the current WAS/RLAN operating conditions in the band 5 2505 350 MHz are sufficient for WAS/RLAN users. NOC USA/1.16/2 5 250-5 570 MHz Allocation to services Region 1 Region 2 Region 3 … 5 350-5 460 EARTH EXPLORATION-SATELLITE (active) 5.448B RADIOLOCATION 5.448D AERONAUTICAL RADIONAVIGATION 5.449 SPACE RESEARCH (active) 5.448C 5 460-5 470 EARTH EXPLORATION-SATELLITE (active) RADIOLOCATION 5.448D RADIONAVIGATION 5.449 SPACE RESEARCH (active) 5.448B … Reasons: Previous ITU-R studies show that sharing between WAS/RLAN and the EESS (active) systems or between WAS/RLAN and different radar systems in the band 5 350-5 470 MHz would not be feasible unless WAS/RLAN implement additional mitigation measures. After further review of currently available mitigation measures, study results show that there are no feasible mitigation techniques to facilitate sharing between WAS/RLAN and EESS (active) or between WAS/RLAN and radar systems in the 5 350-5 470 MHz band.

In Region 2, the band 5 725-5 825 MHz is also used by WAS/RLAN. NOC USA/1.16/4 5 570-6 700 MHz Allocation to services Region 1 Region 2 Region 3 … 5 850-5 925 FIXED FIXED-SATELLITE (Earth-to-space) MOBILE 5 850-5 925 FIXED FIXED-SATELLITE (Earth-to-space) MOBILE Amateur Radiolocation 5 850-5 925 FIXED FIXED-SATELLITE (Earth-to-space) MOBILE Radiolocation 5.150 5.150 5.150 … Reasons: The mobile service is co-primary in the 5 850-5 925 MHz band. Various countries have already implemented RLAN applications under the mobile allocation in this band. Therefore, any sharing analysis carried out under this agenda item should not prejudice usages of the mobile service and should not consider imposing any additional constraints on other allocated services in the band. Since multiple applications are being considered for implementation in this band, it is premature to consider regulatory changes at this time. ____________________ UNITED STATES OF AMERICA PROPOSALS FOR THE WORK OF THE CONFERENCE Agenda Item 9.1 issue 9.1.5: Consideration of the technical and regulatory impacts of referencing Recommendations ITU-R M.1638-1 and ITU-R M.1849-1 in Nos. 5.447F and 5.450A of the Radio Regulations (WRC-15). Background Information: WRC-03 allocated the 5 150-5 350 MHz and 5 470-5 725 MHz frequency bands to the mobile service on a primary basis for the implementation of Wireless Access Systems (WAS) including Radio Local Area Networks (RLANs) subject to Resolution 229 (Rev. WRC-12). WRC-03 also decided that the radiolocation service, the Earth exploration-satellite service (active), the space research service (active) (No. 5.447F), and the radiodetermination service (No. 5.450A) shall not impose on the mobile service more stringent protection criteria, based on system characteristics and interference criteria, than those stated in Recommendations ITU-R M.1638-0 and ITU-R RS.1632-0, which are incorporated in the Radio Regulations by reference. Since WRC-03, millions of RLAN devices have been deployed worldwide. ITU-R revised Recommendation M.1638-0 during the WRC-15 study cycle. The revised recommendation (M.1638-1) included several new radars with different system characteristics, and removed the technical characteristics and protection criteria for ground-based meteorological radars, which were placed in Recommendation ITU-R M.1849-1 instead. Several new meteorological radars were also added to Recommendation ITU-R M.1849-1 during this revision process. This document proposes to modify Nos. 5.447F and 5.450A to remove the references to Recommendations ITU-R M.1638-1 and M.1849-1 while retaining the same regulatory status for the allocated services. Proposal: Article 5 Frequency Allocations Section IV – Table of Frequency Allocations (See No. 2.1) MOD USA/9.1.5/1 5.447F In the frequency band 5 250-5 350 MHz, stations in the mobile service shall not claim protection from the radiolocation service, the Earth exploration-satellite service (active) and the space research service (active) while the radiolocation service, the Earth exploration–satellite service (active) and the space research service (active) shall not impose more stringent technical and operational limits upon the mobile service than those in 5.446A. Reasons: The proposed changes will allow the allocated services to retain the same regulatory status without referencing the subject recommendations in the footnotes of the Radio Regulations. As the responsible ITU-R group routinely updates radar characteristics based on administration proposals, this solution will ensure timely consideration of radar characteristics changes without requiring conference action to modify the footnotes that reference the recommendations. MOD USA/9.1.5/2 5.450A In the frequency band 5 470-5 725 MHz, stations in the mobile service shall not claim protection from radiodetermination service while the radiodetermination service shall not impose more stringent technical and operational limits upon the mobile service than those in 5.446A. Reasons: The proposed changes will allow the allocated services to retain the same regulatory status without referencing the subject recommendations in the footnotes of the Radio Regulations. As the responsible ITU-R group routinely updates radar characteristics based on administration proposals, this solution will ensure timely consideration of radar characteristics changes without requiring conference action to modify the footnotes that reference the recommendations. ____________________ UNITED STATES OF AMERICA 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, in accordance with Article 7 of the Convention. Background Information: At WRC-15 CITEL put forward Inter-American Proposals for an item to be placed on the draft agenda of WRC-23 and a resolution calling for supporting studies. These proposals, agreed at WRC-15, supported an allocation to the Earth exploration-satellite (active) service in the frequency range 40-50 MHz. The draft agenda item is number 2.2 in Resolution 810 (WRC-15), and the supporting studies are called for in Resolution 656 (WRC-15). The United States continues to support the retention of this item on the agenda of WRC-23. There is an interest among space agencies in using active spaceborne sensors in the 40-50 MHz frequency range for measurements of the Earth’s subsurface to provide radar maps of subsurface scattering layers with the intent to locate water/ice deposits. Measurements at the 40-50 MHz frequency range allow the discernment of details at more than 30 meters below the surface of the Earth for favorable ground conditions. Use of frequencies below 40-50 MHz would require larger antenna, which would present difficulties to spaceborne missions implementing this application. Use of frequencies above 40-50 MHz would reduce the depth at which the spaceborne radar sounder could provide measurements. Use of a frequency range other than 40-50 MHz would require new aeronautical campaigns at the different frequency in order to assess and calibrate the measurements at that frequency for use in a spaceborne radar sounder mission. The information obtained from a spaceborne radar sounder operating in the 40-50 MHz frequency range would be of great value to ongoing global climate change studies, and to administrations in their assessment of below surface water resources within their territories. Repetitive measurements of worldwide subsurface water deposits can only be practically implemented using spaceborne active sensors. The 40-50 MHz frequency range is allocated to the fixed, mobile and broadcasting services on a primary basis. The uses of the 40.98 to 41.015 MHz frequency band by space research service are on secondary basis. Country footnotes in the Table of Frequency Allocations for the 40-50 MHz frequency range provide primary allocations for aeronautical navigation and radiolocation services in certain parts of the world. Recommendation ITU-R RS.2042-0 provides typical technical and operating characteristics for spaceborne radar sounder systems in the 40-50 MHz band for use in interference and compatibility studies. This future conference agenda item proposes to study the compatibility of spaceborne radar sounder operations in the 40-50 MHz frequency range with the existing allocated services. In addition, it would investigate a potential modification to the Table of Frequency Allocations to add an allocation to the Earth exploration-satellite service (active). This allocation would allow for the operation of spaceborne radar sounder systems in the 40-50 MHz frequency range. Proposals: ADD USA/10/1 DRAFT NEW RESOLUTION [USA-AXXX] Agenda for the 2023 World Radiocommunication Conference The World Radiocommunication Conference (Sharm el-Sheikh, 2019), ... X.X1 to conduct, and complete in time for WRC-23, studies for a possible new allocation to the Earth exploration-satellite (active) service for spaceborne radar sounders within the range of frequencies around 45 MHz, taking into account the protection of incumbent services, in accordance with Resolution 656 (WRC-15); Reasons: To conduct studies to examine the compatibility of spaceborne radar sounder operations in the 40-50 MHz frequency range with existing allocated services and to potentially modify the Table of Frequency Allocations to add an allocation to the Earth exploration-satellite service (active) allowing for the operation of spaceborne radar sounder systems in the 40-50 MHz frequency range. NOC USA/10/2 RESOLUTION 656 (WRC15) Possible allocation to the Earth exploration-satellite service (active) for spaceborne radar sounders in the range of frequencies around 45 MHz The World Radiocommunication Conference (Geneva, 2015), Reasons: Resolution 656 (WRC-15) calls for the studies supporting this agenda item. Consequential changes are unnecessary. SUP USA/10/3 RESOLUTION 810 (WRC15) Preliminary agenda for the 2023 World Radiocommunication Conference The World Radiocommunication Conference (Geneva, 2015), Reasons: This Resolution must be suppressed, as WRC-19 will create a new Resolution that will include the agenda for WRC-23. DOCUMENT WAC/062 (06.09.18) September 6, 2018 Mr. Tom Sullivan Chief, International Bureau Federal Communications Commission 445 12th Street, SW Washington, DC 20554 Dear Mr. Sullivan: The National Telecommunications and Information Administration (NTIA), on behalf of the Executive Branch agencies, approves the release of the enclosed proposals for the 2019 World Radiocommunication Conference (WRC-19) which address: 1. Agenda item 1.13 – International Mobile Telecommunications (IMT) studies between 24.25 GHz and 86 GHz with proposals for the 31.8-33.4 GHz, 45.5-47 GHz, and 47-47.2 GHz bands 2. Agenda item 9.1, issue 9.1.6 – Urgent studies for Wireless Power Transfer (WPT) for electric vehicles NTIA considered the federal agencies’ input toward the development of these U.S. proposals for WRC-19. NTIA forwards this package for your consideration and review. If you have any questions, please contact Mr. Charles Glass, our WRC Coordinator, who can be reached at (202) 482-1896 or cglass@ntia.doc.gov. Sincerely, Peter A. Tenhula Acting Associate Administrator Office of Spectrum Management Enclosures (2) Attachment 1 United States PROPOSALS FOR THE WORK OF THE CONFERENCE Agenda item 1.13 1.13 to consider identification of frequency bands for the future development of International Mobile Telecommunications (IMT), including possible additional allocations to the mobile service on a primary basis, in accordance with Resolution 238 (WRC-15); Background Information: Resolution 238 (WRC-15) invites ITU-R to conduct and complete in time for WRC-19 appropriate studies to determine the spectrum needs for the terrestrial component of IMT in the frequency range between 24.25 GHz and 86 GHz, as well as sharing and compatibility studies, taking into account the protection of services to which the frequency band is allocated on a primary basis, for the frequency bands: – 24.25-27.5 GHz “When conducting studies in the frequency band 24.5-27.5 GHz, to take into account the need to ensure the protection of existing earth stations and the deployment of future receiving earth stations under the EESS (space-to-Earth) and SRS (space-to-Earth) allocation in the frequency band 25.527 GHz.” , 37-40.5 GHz, 42.5-43.5 GHz, 45.5-47 GHz, 47.2-50.2 GHz, 50.452.6 GHz, 66-76 GHz and 81-86 GHz, which have allocations to the mobile service on a primary basis; and – 31.8-33.4 GHz, 40.5-42.5 GHz and 47-47.2 GHz, which may require additional allocations to the mobile service on a primary basis. The Resolution further invites WRC-19 to consider, based on the results of these studies, additional spectrum allocations to the mobile service on a primary basis and identification of frequency bands for the terrestrial component of IMT. The bands to be considered are limited to part or all of the bands listed above. 31.8-33.4 GHz: Sharing and compatibility studies were conducted between IMT-2020 systems and the following systems in the 31.8-33.4 GHz range: radionavigation service (RNS), space research service (Deep Space) (SRS), Earth exploration-satellite (EESS) (passive), and radio astronomy service (RAS). The results are briefly summarized as follows: Ø RNS: The studies show that sharing between IMT-2020 systems and the radionavigation service within 31.8-33.4 GHz is not feasible Ø SRS: The study results indicate that the separation distances needed to protect these particular facilities are relatively small; consequently, the protection of these stations could be considered on a national or bilateral/multilateral level. Ø EESS (passive): The studies show interference exceedance. Ø RAS: The studies show that separation distances of 19-49 km are needed. 45.5-47 GHz: No studies were performed between IMT-2020 systems in this band and the relevant incumbent services. 47-47.2 GHz: No studies were performed between IMT-2020 systems in this band and the relevant incumbent services.

SUP USA/4773A13/3 RESOLUTION 238 (WRC15) Studies on frequency-related matters for International Mobile Telecommunications identification including possible additional allocations to the mobile services on a primary basis in portion(s) of the frequency range between 24.25 and 86 GHz for the future development of International Mobile Telecommunications for 2020 and beyond The World Radiocommunication Conference (Geneva, 2015), Reasons: The studies called for under the agenda item for most of the bands have been completed. The fact that no studies on the 45.5-47 GHz band or the 47-47.2 GHz band, which were called for under the agenda item, have been performed indicates no interest in these bands for IMT-2020. There is no need to retain Resolution 238 (WRC-15). ____________________________________________________ 30 Attachment 2 United States PROPOSALS FOR THE WORK OF THE CONFERENCE Agenda item 9, Issue 9.1.6 9 to consider and approve the Report of the Director of the Radiocommunication Bureau, in accordance with Article 7 of the Convention: 9.1 on the activities of the Radiocommunication Sector since WRC-15; 9.1 (9.1.6) Resolution 958 (WRC-15) - Annex item 1) Studies concerning Wireless Power Transmission (WPT) for electric vehicles: a) to assess the impact of WPT for electric vehicles on radiocommunication services; b) to study suitable harmonized frequency ranges which would minimize the impact on radiocommunication services from WPT for electrical vehicles. These studies should take into account that the International Electrotechnical Commission (IEC), the International Organization for Standardization (ISO) and the Society of Automotive Engineers (SAE) are in the process of approving standards intended for global and regional harmonization of WPT technologies for electric vehicles; Background Information: WPT technologies are being developed worldwide to support many applications to transfer power without employing any wired connection. WPT for electric vehicles (WPT EV) applications are part of the WPT development efforts. The objectives of WPT EV developments are to reduce EV battery size, increase the driving distance between charging, and improve the practicality by making EV charging stations more available and accessible for consumers, governments, and other public transit authorities. WRC-15 adopted Resolution 958 (WRC-15) to examine the possible impact of WPT EV charging on the radiocommunication services. Annex item 1 of the resolution requests, as a matter of urgency, that ITU-R study the impact of WPT EV on radiocommunication services and study suitable harmonized frequency ranges that would minimize this impact. ITU-R identified two frequency ranges for EV charging that might be suitable for harmonization: the 79-90 kHz frequency range for medium power and 19-25 kHz for high power. ITU-R conducted a number of impact studies between WPT EV and radiocommunication services to assess the potential interference impact of WPT EV applications operating within the 19-25 kHz and 79-90 kHz frequency ranges. These analyses are included in Report ITU-R SM.2303, [the working document towards a preliminary draft new] Report SM.[WPT_SPEC_MNGM], and [the working document towards a preliminary draft revision of] Recommendation ITU-R SM.2110. Upon approval of these documents, the urgent studies requested in Resolution 958 (WRC-15) Annex 1 (b) will have been addressed. The power level of WPT EV selected to charge an EV battery will depend on the circumstances and requirements of the users. In most cases for electric vehicles, the charger will be located in a residential setting, with power levels between 3.3 kW and 22 kW. It will likely take a number of hours to fully charge the EV battery within this power range. These characteristics provide a suitable balance between domestic electrical load limitations, charging time considerations, and other regulations governing electrical installations for domestic use. However, where users need higher charging rates to satisfy specific heavy-duty vehicle use (such as buses, trams, and trucks), much higher power levels may be needed to reduce the charging times to satisfy commercial and operational demands. A minimum of 75 kW equivalent charging power is likely to be required initially, and the requirement will increase to several hundred kW for certain intensively used heavy-duty vehicles. WPT does not have any status in the Radio Regulations; therefore, it should not cause interference to radiocommunication services. For the frequency ranges proposed for harmonized WPT EV use, Nos. 15.12 and 15.12.1 apply to ensure that electrical apparatus of any kind does not cause harmful interference to a radiocommunication service and that administrations should be guided by the latest ITU-R Recommendations in this matter. Recommendation ITU-R SM.2110 provides further information on the regulatory status of WPT. NOC USA/4775A21A6/1 ARTICLE 5 Frequency allocations Reasons: Based on ITU-R studies conducted and analyses made per Resolution 958 (WRC-15) Annex 1, the impact on radiocommunication services from WPT EV can be minimized by the application of power limits, separation distances, and careful control of harmonic energy, including the selection of WPT EV fundamental frequency within the frequency ranges. The fundamental frequency selection may need to take into account regional differences. Further, [working document towards a preliminary draft new] Report ITU-R SM.[WPT_SPEC_MNGM] provides the required power limitations and associated frequency ranges. Therefore, it is unnecessary to make any modifications to the Radio Regulations or to the regulatory status of WPT for the introduction of WPT EV applications. These applications can be developed, deployed, and used effectively within the existing regulatory framework in accordance with Nos. 15.12 and 15.12.1 and regional and individual administration’s authorization requirements. Additional guidance for administrations wishing to deploy WPT EV applications can be found in ITU-R Reports and Recommendations, including [the working document towards a preliminary draft new] Report ITU-R SM.[WPT_SPEC_MNGM] and the latest version of Recommendation ITU-R SM. 2110.

Tenhula Acting Associate Administrator Office of Spectrum Management Enclosures (17) United States PROPOSALS FOR THE WORK OF THE CONFERENCE Agenda item 1.2 Agenda Item 1.2: to consider in-band power limits for earth stations operating in the mobile-satellite service, meteorological-satellite service, and Earth exploration-satellite service in the frequency bands 401-403 MHz and 399.9-400.05 MHz, in accordance with Resolution 765 (WRC-15) BACKGROUND: Resolution 765 (WRC-15) resolves to invite the WRC-19 to take into account the results of ITU-R studies and consider the possibility of establishing in-band power limits for Earth stations in the EESS and MetSat in the frequency bands 401- 403 MHz and in the MSS frequency band 399.9-400.05 MHz. Earth stations operating in the Earth exploration-satellite service (EESS) and meteorological-satellite service (MetSat) in the frequency band 401-403 MHz and in the mobile-satellite service (MSS) in the frequency band 399.9-400.05 MHz are used for data collection systems (DCS) uplinks. These DCS usually operate most efficiently together by using moderate to low equivalent isotropic radiated power (e.i.r.p) levels, resulting in small link margins. Recommendation ITU-R SA.2045 provides information on the performance and interference criteria for relevant geostationary-satellite orbit (GSO) and non-geostationary satellite (non-GSO) DCS in the frequency band 401-403 MHz. Recommendation ITU-R SA.2044 provides information on the current and future usage of non-GSO DCS in the frequency band 401-403 MHz, and the portioning of the frequency band to allow all DCS equal access to the spectrum. Recommendation ITU-R M.2046 provides a description, and the corresponding protection criteria for broadband noise and narrowband interference, of one MSS system that uses the frequency band 399.9-400.05 MHz (Earth-to-space). Tens of thousands of DCS stations communicating with GSO and non-GSO satellites are deployed worldwide for the purpose of collecting essential weather and climate data. The Data Collection Platforms (DCP) gather information activity related to the Earth, environmental and scientific applications, weather, environment observation: meteorological and oceanographic, seismic observation, volcanology, geodesy and geodynamics, fishing vessel monitoring, wildlife tracking, homeland security, law enforcement, test/evaluation, monitoring shipments of dangerous goods, humanitarian applications, managing water resources or tsunami warning system, etc. The data collected by DCPs are transmitted to satellites in visibility of these platforms that relay the retrieved information to dedicated earth stations. EESS, MetSat, and MSS systems are indispensable for monitoring and predicting climate change; monitoring oceans, weather, and water resources. Additionally, these systems assist in protecting biodiversity, and improve maritime safety, and security. There is a growing number of satellite operators planning to use these frequency bands for telecommand purposes under the EESS, MetSat, and MSS allocations. The output power levels of these Earth stations at the antenna port for telecommand links (Earth-to-space) can be much higher than the moderate to low power levels traditionally used for the operation of EESS, MetSat, and MSS DCS systems, in the frequency bands 401-403 MHz and 399.9-400.05 MHz. ITU-R study is considering specific in-band power limits for earth stations operating in the frequency ranges 399.9-400.05 MHz in the MSS and 401-403 MHz in the EESS and MetSat services.

ADD USA/AI 1.2/3 5.B102 In the frequency band 401-403 MHz, the maximum e.i.r.p. transmission at the input of the antenna from any Earth stations (Earth-to-space) in the meteorological-satellite service and the Earth exploration-satellite service shall not exceed 22 dBW for geostationary-satellite orbit systems and non-geostationary-satellite orbit systems with an orbital apogee equal to or greater than 35 786 km and 7 dBW for non-geostationary-satellite orbit systems with an orbital apogee lower than 35 786 km. These provisions shall apply to all Earth stations (Earth-to-space) in the meteorological-satellite service and the Earth exploration-satellite service operating in this frequency band after 1 January 2024. These limits shall not apply to all Earth stations (Earth-to-space) of associated satellite systems in the meteorological-satellite service and the Earth exploration-satellite service in this frequency band for which complete notification information has been received by the Radiocommunication Bureau before 22 November 2019. Reasons: Establish Earth station e.i.r.p. limits to ensure the operations of both GSO and non-GSO data collection systems in the 401-403 MHz frequency band. ADD USA/AI 1.2/4 5.C102 In the frequency band 401.898-402.522 MHz, the maximum e.i.r.p. transmission at the input of the antenna from Earth stations (Earth-to-space) of associated satellite system for which complete notification information was received by the Radiocommunication Bureau on 28 April 2007, may continue to operate at their current level. Reasons: This provision provide flexibility to existing Earth station(s) of associated non-GSO system and it ensure the continued operation of this non-GSO data collection systems. SUP USA/AI 1.2/5 RESOLUTION 765 (WRC-15) Establishment of in-band power limits for earth stations operating in mobile-satellite service, the meteorological-satellite service and the Earth exploration-satellite service in the frequency bands 401-403 MHz and 399.9-400.05 MHz Reasons: Consequential actions to establishing in-band power limits for Earth stations operating in the mobile-satellite service, the meteorological-satellite service and the Earth-exploration-satellite service in the frequency bands 399.9-400.05 MHz and 401-403 MHz. __________ United States PROPOSALS FOR THE WORK OF THE CONFERENCE Agenda item 1.3 Agenda Item 1.3: to consider possible upgrading of the secondary allocation to the meteorological-satellite service (space-to-Earth) to primary status and a possible primary allocation to the Earth exploration-satellite service (space-to-Earth) in the frequency band 460-470 MHz, in accordance with Resolution 766 (WRC-15) BACKGROUND: The 460-470 MHz frequency 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. Under No. 5.289, “Earth exploration-satellite service applications, other than the meteorological-satellite service, may also be used in the bands 460-470 MHz for space-to-Earth transmissions subject to not causing harmful interference to stations operating in accordance with the Table”. Within this frequency band, the Argos Data Collection System (ADCS) monitors more than 21,000 active Argos platforms collecting data for over 2,000 distinct projects in 100+ countries. The administration of the Argos program is under a joint agreement between the National Oceanic and Atmospheric Administration (NOAA) within the United States and the French Space Agency, Centre National d’Etudes Spatiales (CNES). Additional partners include the European Organization for the Exploitation of Meteorological Satellites (EUMETSAT), and the Indian Space Research Organization (ISRO). Critical applications of the ADCS include atmospheric and ocean monitoring/research, tropical cyclone forecasting, fishery management, oil spill tracking, fishing vessel tracking, search and rescue modeling (at sea), anti-piracy alerting, import/export and hazardous materials tracking, endangered species studies, migration mapping, and wildlife tracking and management. The meteorological-satellite (space-to-Earth) service operates on a secondary basis relative to the fixed and mobile services and thus it must not interfere with these services. To protect the fixed and land mobile services within the United States, a power flux density (pfd) of -152 dB(W/(m2∙4kHz)) has been imposed on the meteorological-satellite (space-to-Earth) service. In accordance with Resolution 766 (WRC-15), the ITU-R has conducted sharing studies to ensure the protection of incumbent services and to develop a pfd limit that will protect incumbent services globally from potential interference in the frequency band 460 – 470 MHz. Studies have demonstrated that sharing is possible between meteorological-satellite (space-to-Earth)/earth-exploration-satellite (space-to-Earth) services and the incumbent services in the 460 – 470 MHz frequency band if the pfd limits proposed below are applied. Based on the results of sharing studies, this proposal supports an allocation upgrade from secondary to a primary for the meteorological-satellite service (space-to-Earth) and a new primary allocation to the earth-exploration-satellite (space-to-Earth) service in the frequency band 460 – 470 MHz band. This proposal applies a set of elevation angle dependent pfd limits to the meteorological-satellite and earth exploration-satellite services to protect the incumbent services globally. Proposal: ARTICLE 5 Frequency allocations Section IV – Table of Frequency Allocations (See No. 2.1) MOD USA/AI 1.3/1 460-470 MHz Allocation to services Region 1 Region 2 Region 3 460-470 FIXED MOBILE 5.286AA METEOROLOGICAL-SATELLITE (space-to-Earth) EARTH-EXPLORATION-SATELLITE (space-to-Earth) 5.287 5.288 5.290 ADD 5.A103 ADD 5.B103 ADD 5.C103 Reason: The upgrade from the secondary MetSat and EESS allocations to primary will bring regulatory stability and certainty to the space agencies involved in Satellite Data Collection Programs. With this upgrade, inclusion of this band in footnote 5.289 is no longer necessary. Also, this upgraded allocation will ease coordination effort for Administrations. .

If an administration believes that, in this band transhorizon systems need to be considered, the parameters associated with the frequency band 2 500-2 690 MHz may be used to determine the coordination area. 2 A: analogue modulation; N: digital modulation. 3 E is defined as the equivalent isotropically radiated power of the interfering terrestrial station in the reference bandwidth. 4 This value is reduced from the nominal value of 50 dBW for the purposes of determination of coordination area, recognizing the low probability of high power emissions falling fully within the relatively narrow bandwidth of the earth station. 5 The fixed-service parameters provided in the column for 163-167 MHz and 272-273 MHz are only applicable to the band 163-167 MHz.

ADD USA/AI 1.3/6 DRAFT NEW RESOLUTION [B103] (WRC-19) Implementation of satellite networks and systems of the meteorological-satellite service (space-to-Earth) and the Earth exploration-satellite service (space-to-Earth) in the frequency band 460-470 MHz The World Radiocommunication Conference (Sharm el-Sheikh, 2019), considering a) that data collection systems (DCS) operate on geostationary and non-geostationary orbits in the meteorological-satellite service (MetSat) and the Earth exploration-satellite service (EESS) (Earth-to-space) in the frequency band 401-403 MHz; b) that DCS are essential for monitoring and predicting climate change, monitoring oceans, and water resources, weather forecasting and assisting in protecting biodiversity, improving maritime security; c) that most of these DCS have implemented satellite downlinks (space-to-Earth) in the frequency band 460-470 MHz which bring significant improvements to the operation of satellite DCS, such as the transmission of information to optimize the usage of the terrestrial data collection platforms; d) that the frequency band 460-470 MHz is also used for the downlink of mission and telemetry data for meteorological and earth exploration purposes; e) that the frequency band 460-470 MHz is allocated to the fixed and mobile services on a primary basis and is widely used by these services; f) that the WRC-19 has upgraded the secondary allocation of the MetSat (space-to-Earth) to primary status and added a primary allocation to the EESS (space-to-Earth) in the frequency band 460-470 MHz, and established the power flux-density (pfd) limit to provide protection of existing terrestrial services; g) that the priority of MetSat systems over EESS systems in the frequency band 460-470 MHz is provided to ensure protection of MetSat systems from interference from the increasing number of small satellite systems operating in the EESS; h) that WRC-19 suppress No. 5.290 and the relevant parameters in Table 8a of Appendix 7, which identified some administrations that already have a primary allocation to the MetSat (space-to-Earth), subject to agreement obtained under No. 9.21, in the light of the upgrade mentioned in considering f) above, and that it is necessary to provide some regulatory measures for satellite systems which operate in accordance with No. 5.290 to retain their regulatory status after the end of WRC-19, noting a) that several EESS and MetSat satellite systems in the frequency band 460-470 MHz were notified and brought into use; b) that some of these EESS and MetSat satellite systems above may not meet the pfd limit in considering f), but there is a need to authorize them under the previous provision in order to continue their operations, resolves 1 that in the frequency band 460-470 MHz, in order to protect systems of the fixed and mobile services, the power flux-density at the Earth’s surface produced by stations in the meteorological-satellite (space-to-Earth) and earth exploration-satellite (space-to-Earth) services shall comply with the limits listed below under assumed free-space propagation conditions for all methods of modulation: For non-GSO space stations: pfd dBWm2 · 4kHz=-157 &0°≤<5° -157+0.5α-5 5°≤<15°-152 15°≤≤90° And for GSO space stations: pfd (dBW/(m2.4kHz))=-162 &0°≤a≤15° -162+0.5α-15 15°
