ATTACHMENT B to FCC Public Notice DA 19-172 Draft Proposals presented for information and not formally agreed by the World Radiocommunication Conference Advisory Committee DOCUMENT WAC/081 (11.03.19) UNITED STATES OF AMERICA PROPOSALS FOR THE WORK OF THE CONFERENCE Agenda item 10 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: Historically, aeronautical HF (High Frequency) Radio communications has been recognized as the primary long-range communication system for safe, efficient air travel in remote or oceanic areas beyond the range of ground-based VHF radios. Current HF analog single sideband systems are susceptible to static crashes from lightning and man-made noise, as well as selective fading as the atmosphere continually changes. Future HF voice systems can move to more advanced digital voice as many CODECS (Coder/Decoders) are now available commercially. Modem technology has evolved significantly over the last 27 years and techniques such as Automatic Link Establishment allow HF radios to find and link on the best available frequency at a given time. The use of spectrally efficient modulation techniques and bonding consecutive HF channels (for Wide-Band HF (WBHF)) will enable technology improvements that will support high rate data transmissions. Development of the next generation of HF data communications will enable achieving Required Communications Performance (RCP)-240 Manual on Required Communication Performance, ICAO Doc 9869 AN/462, 2006 compliance for the delivery of ATC traffic, provide for a digital voice capability that will address the frequent complaints about the noisy nature of analog HF voice communications and enable reduction in flight crew workload by automatically assigning frequencies to aircraft radios by leveraging modern protocols. This effort will allow Terrestrial HF and space-based systems (Satcom) to work well together in a complementary and synergistic fashion to offer better performance, reliability and availability than either system alone. Having both space-based and modernized terrestrial HF long range communication mitigates single point of failure concerns associated with vulnerabilities which differ for each system (e.g., solar events, rain fade, jamming, hardware failures, etc.). It is in the interest of administrations and industry to review and revise the ITU Radio Regulation Appendices 26 and 27 to provide the relevant regulatory framework to realize the above stated capabilities for aviation use (including aviation safety of life) and enable the coexistence of current HF systems alongside modernized HF systems that deliver the above mentioned capabilities. ICAO has considered modernization of the way HF spectrum is utilized and endorses FSMP-WG08-Flimsy07 WRC-23 Agenda Item for HF Rev1 - Final.docx a revision of Appendix 27 for a WRC-23 Agenda Item. Proposals SUP USA/10(XXX)/1 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. ADD USA/10(XXX)/2 DRAFT NEW RESOLUTION [USA-2023] Agenda for the 2023 World Radiocommunication Conference The World Radiocommunication Conference (Geneva, 2015), considering a) that, in accordance with No. 118 of the ITU Convention, the general scope of the agenda for a world radiocommunication conference should be established four to six years in advance and that a final agenda shall be established by the Council two years before the conference; b) Article 13 of the ITU Constitution relating to the competence and scheduling of world radiocommunication conferences and Article 7 of the Convention relating to their agendas; c) the relevant resolutions and recommendations of previous world administrative radio conferences (WARCs) and world radiocommunication conferences (WRCs), resolves to recommend to the Council that a world radiocommunication conference be held in 2023 for a maximum period of four weeks, with the following agenda: 1 on the basis of proposals from administrations, taking account of the results of WRC15 and the Report of the Conference Preparatory Meeting, and with due regard to the requirements of existing and future services in the bands under consideration, to consider and take appropriate action in respect of the following items: 1.[XXX] to consider, on the basis of ITU-R studies in accordance with Resolution [USA/10/WIDEBAND HF] (WRC-19), appropriate regulatory actions, updates to revise ITU - R Appendices 26 and 27 in support of Wideband HF; resolves further to activate the Conference Preparatory Meeting, invites the Council to finalize the agenda and arrange for the convening of WRC23, and to initiate as soon as possible the necessary consultations with Member States, instructs the Director of the Radiocommunication Bureau to make the necessary arrangements to convene meetings of the Conference Preparatory Meeting and to prepare a report to WRC23, instructs the Secretary-General to communicate this Resolution to international and regional organizations concerned. Reasons: The aeronautical use of the various HF frequency bands in the range 2 850 – 22 000 kHz is essential to long distance aeronautical communications in remote and oceanic areas. Since the last substantive review of Appendices 26 and 27 of the ITU Radio Regulations, use of HF by aviation has continued to change and grow, especially for HF Datalink (HFDL) services used by many aircraft. Aviation is evaluating future developments within the HF band, using new technology to significantly improve capacity, connectivity, and quality of service for aviation data and voice, including increased channel bandwidths for greater data throughput. Such developments within existing aviation HF allocations would provide aviation with additional capabilities, improving safety, global coverage and link diversity to L-band SATCOM systems thus allowing updated HF systems to work well together in a complementary and synergistic fashion with Satcom systems to better maintain communications at all times. In light of the evolving HF technologies, Appendices 26 and 27 need to be reviewed to ensure they meet the current and future aeronautical requirements by allowing for bonding contiguous HF channels and allow digital modulations that support higher data rates while ensuring that interference outside of the assigned multi-channel bands is no greater than the interference of individually utilized channels.

Background/reason: The aeronautical use of the various HF frequency bands in the range 2 850 – 22 000 kHz is essential to long distance aeronautical communications in remote and oceanic areas.

Some of this re-purposed spectrum is in the 600 MHz and 700 MHz bands which are heavily used by ENG. There is a general incompatibility in co-channel spectrum sharing between IMT and wireless ENG tools, particularly wireless microphones (where the definition of wireless microphones includes a wide variety of production tools such as intercom systems, in-ear monitors, and interruptible fold-back systems). For example, in the United States the repurposing of the 700 MHz band in 2010, and 600 MHz band currently in transition, not only has and will reduce TV broadcast spectrum, but will also displace a large portion of ENG operations. Other countries are now, or soon will be, undergoing a similar process. This re-purposing of spectrum from traditional TV broadcast to mobile broadband is an issue of the distribution of content. ENG fuels the creation of content and live event programs. Demand for news and entertainment content has never been more robust, and is accelerating. Wireless microphones are used in the creation of virtually all content today, regardless of how that content is consumed: through TV, radio, laptop, tablet, cell phone, or in person. Furthermore, productions are increasingly more sophisticated, requiring more audio channels, many of them with high definition resolution. This long-term trend is clear and will inevitably continue. Worldwide, virtually all professional wireless microphones currently operate in the UHF TV band because this spectrum fulfills the requirements of demanding microphone applications, but will need alternative spectrum because of declining available of UHF TV spectrum in the 600 and 700 MHz bands, and increasing demand for content. Some administrations, including the United States, have recognized the importance and ubiquitous nature of wireless microphones and are attempting to accommodate the strong demand for news and content creation by permitting wireless microphones to also operate in alternative bands, outside TV spectrum, that are suitable for ENG applications, including 169-172 MHz and 941.5-960 MHz. As other administrations also transition from analogue TV to digital TV and mobile broadband, it is in the interests of administrations and industry to study and harmonize frequency bands and tuning ranges, as intended by Resolution ITU-R 59-1. Harmonization would provide economies of scale and logistical practicality, especially for networks and production companies that must cover events in multiple countries, such as global news, elections, international sport events, conferences, and concert tours. ENG crews also provide early and essential disaster alert information. Proposal: SUP USA/10(XXX)/1 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. ADD USA/10(XXX)/2 DRAFT NEW RESOLUTION [USA-2023] Agenda for the 2023 World Radiocommunication Conference The World Radiocommunication Conference (Geneva, 2015), considering a) that, in accordance with No. 118 of the ITU Convention, the general scope of the agenda for a world radiocommunication conference should be established four to six years in advance and that a final agenda shall be established by the Council two years before the conference; b) Article 13 of the ITU Constitution relating to the competence and scheduling of world radiocommunication conferences and Article 7 of the Convention relating to their agendas; c) the relevant resolutions and recommendations of previous world administrative radio conferences (WARCs) and world radiocommunication conferences (WRCs), resolves to recommend to the Council that a world radiocommunication conference be held in 2023 for a maximum period of four weeks, with the following agenda: 1 on the basis of proposals from administrations, taking account of the results of WRC15 and the Report of the Conference Preparatory Meeting, and with due regard to the requirements of existing and future services in the bands under consideration, to consider and take appropriate action in respect of the following items: 1.[XXX] to consider, on the basis of ITU-R studies in accordance with Resolution [USA/10/XX] (WRC-19), appropriate regulatory actions, Studies on additional frequency bands outside the 600 MHz and 700 MHz bands between 150 MHz to 2 000 MHz, and worldwide and/or regional harmonization for terrestrial electronic news gathering systems; 1. ENG resolves further to activate the Conference Preparatory Meeting, invites the Council to finalize the agenda and arrange for the convening of WRC23, and to initiate as soon as possible the necessary consultations with Member States, instructs the Director of the Radiocommunication Bureau to make the necessary arrangements to convene meetings of the Conference Preparatory Meeting and to prepare a report to WRC23, instructs the Secretary-General to communicate this Resolution to international and regional organizations concerned. Reasons: Demand for ENG content is robust and accelerating. Currently, nearly all ENG audio tools (i.e., wireless microphones) operate in the UHF TV band, including the 600 MHz and 700 MHz bands that many administrations are re-allocating. As UHF spectrum is re-purposed from traditional analog TV to digital TV and mobile broadband, alternative suitable frequency bands are being made available for ENG applications. It is in the interests of administrations and industry to chart a smooth transition from the 600 MHz and 700 MHz to standardized alternate frequency bands that are suitable for ENG, i.e. between 150 to 2 000 MHz. ADD USA/10(XXX)/3 DRAFT NEW RESOLUTION [USA/10/XX] (WRC-19) RESOLUTION [xxx] Studies on additional frequency bands outside the 600 MHz and 700 MHz bands between 150 to 2 000 MHz, and worldwide and/or regional harmonization for terrestrial electronic news gathering For the purpose of this Resolution, ENG represents all audio applications ancillary to broadcasting and programme making (SAB/SAP), such as electronic news gathering, electronic field production, TV outside broadcast, Program Making and Special Events (PMSE), wireless radio microphones and radio outside production and broadcast. systems The World Radiocommunication Conference (Sharm El Sheikh, 2019), Considering a) A large portion of ENG production tools, such as radio microphones, operate in vacant channels (6 MHz or 8 MHz wide) within the 600 MHz and 700 MHz bands; b) that parts of these bands are being repurposed by many administrations from terrestrial TV to mobile broadband, resulting in loss of availability of many channels for ENG operations, approximately 60 MHz at typical locations; c) that the technical nature of most ENG tools results in a general incapability in co-channel spectrum sharing with mobile handsets; d) that administrations will have to transition a large portion of ENG operations to alternate suitable spectrum, outside the 600 and 700 MHz bands; e) that WRC-15 initiated studies concerned with spectrum usage and operational characteristics of portable and nomadic links for terrestrial ENG systems operation in spectrum already allocated for that purpose on a global basis, in accordance with Resolution 59-1; e) that modularization and miniaturization of terrestrial ENG systems has increased the portability for these systems and has thus increased the trend towards cross-border operation of ENG equipment; d) that the technical characteristics for television outside broadcast, ENG and electronic field production systems have been established in ITU-R Recommendations (e.g. ITU-R BT 1871), noting a) that studies undertaken by ITU-R indicate that national spectrum management could benefit from globally harmonized band planning for ENG systems; b) that ENG-related studies in ITU-R are based on data for current and anticipated ENG spectrum requirements collected from many administrations in all regions; c) that the lower frequency spectrum, i.e. less than 2 000 MHz tends to provide better propagation characteristics over obstructed paths, thereby increasing the reliability of ENG links operating in these bands; d) that the demand for ENG content is robust and accelerating, recognizing a) that the production of ENG content continues to become increasingly sophisticated, requiring more channel in higher audio and video resolution formats; b) that the dynamic nature of the use of ENG is driven in part by unscheduled and unpredictable events such as breaking news, emergencies and disasters; c) that news gathering and electronic production typically takes place in an environment where several television broadcasters/organizations/networks attempt to cover the same event, creating a demand for multiple ENG links and increased demand for access to spectrum in suitable frequency bands; d) that handheld and body pack transmitters as well as body worn receivers require compact size, battery operation, sufficient range and small, yet efficient antennas, frequency bands suitable for mobile audio ENG are primarily within the frequency bands of 150 MHz to 2 000 MHz; e) There is a general incompatibility in co-channel spectrum sharing between wireless ENG / PMSE tools and some services that operate in portions of the 150 MHz to 2 000 MHz range. These include IMT; aviation radio services and aeronautical mobile telemetry (AMT) Notwithstanding the “general incompatibility” of wireless microphone co-channel sharing with AMT, the United States administration has allocated spectrum from 1435 - 1525 MHz for AMT with a secondary allocation for wireless microphones. This is subject to stringent coordination requirements. ; Radio Navigation Satellite Service (e.g., GPS); and other satellite downlink bands. Thus, for purposes of global harmonization, the identification of suitable bands will require careful consideration and detailed compatibility studies to ensure protection of these services. f) some administrations have already identified such alternate, suitable spectrum between 150 MHz to 2 000 MHz for ENG (e.g. 941.5 - 960 MHz, 169 -172 MHz in the United States; 960 - 1 164 MHz in the United Kingdom; 1 350 – 1 400 MHz in portions of Region 1); g) Mobile ENG audio tools (i.e. wireless microphones) are low power devices, typically operating with transmitter output power of 50 mW – 250 mW, and have proven to pose a negligible risk of interference to services operating in adjacent channels (e.g. broadcast services); h) that access to globally harmonized spectrum is highly desirable to facilitate the rapid and less restricted deployment and operation of ENG systems from one country to another, resolves 1 that, based on studies undertaken by ITU-R, WRC-23 should address the feasibility of achieving a coordinated transition for ENG operations from the 600 MHz and 700 MHz bands to suitable alternate spectrum between 150 – 2 000 MHz. The amount of alternate spectrum should total approximately 72 MHz, contiguous or separate multiple 6 MHz or 8 MHz channels, to compensate for the loss within the 600 MHz and 700 MHz bands and to accommodate the robust demand for content creation. A portion of this alternate spectrum should be identified in a manner that results in a satisfactory degree of worldwide/regional harmonization of spectrum for ENG use in terms of the frequency bands and tuning ranges The term “tuning range” for ENG means a range of frequencies over which radio equipment is envisaged to be capable of operating; within this tuning range, the use in any one country of radio equipment from another country will be limited to the range of frequencies identified nationally in that one country for ENG, and will be operated in accordance with the related national conditions and requirements. ; 2 that methods should be identified for the possible harmonization of frequency bands and tuning ranges for ENG usage, invites ITU-R 1 to carry out studies of ENG regarding possible solutions for global/regional harmonization in frequency bands and tuning ranges, taking into account: – propagation characteristics at various frequencies; – available technologies to maximize efficient and flexible use of frequency; – system characteristics and operational practices which facilitate the implementation of these solutions; 2 to include in the studies referred to above, sharing and compatibility issues with services already having allocations in frequency bands and tuning ranges which have potential for ENG use; 3 to propose operational measures to facilitate operation of ENG equipment consistent with global circulation of radiocommunication equipment, taking into account Recommendation ITU-R M.1637; 4 to report the results of those studies to the World Radiocommunication Conference 2023 and identify ranges for regional and global harmonization, invites administrations to participate in the studies by submitting contributions to ITU-R. ATTACHMENT PROPOSAL FOR ADDITIONAL AGENDA ITEM TO IDENTIFY AND HARMONIZE FREQUENCY BANDS FOR ENG Subject: Proposed Future WRC Agenda Item for WRC-2023 studying harmonization Origin: United States of America Proposal: To review the frequency bands permitted for ENG, identify alternate bands outside of the 600 MHz and 700 MHz bands, and harmonize them among various administrations. Background/reason: Demand for ENG content is robust and accelerating. Currently, nearly all ENG audio tools (i.e., wireless microphones) operate in the UHF TV band, including the 600 MHz and 700 MHz bands that many administrations are re-allocating. As UHF spectrum is re-purposed from traditional analog TV to digital TV and mobile broadband, alternative suitable frequency bands are being made available for ENG applications. It is in the interests of administrations and industry to chart a smooth transition from the 600 MHz and 700 MHz to standardized alternate frequency bands suitable for ENG above 150 MHz and below 2 000 MHz.

ITU-R has conducted studies required by Resolution 162 (WRC-15). The results of analysis of additional spectrum needs are contained in DN Report ITU-R S.[SPECTRUM_NEEDS]. The results of sharing and compatibility studies with incumbent services including the fixed service (FS), mobile service (MS), Earth exploration-satellite service (EESS) (passive), radio astronomy service (RAS), and sharing with potential IMT-2020 applications are contained in PDN Report ITU-R S.[SPECTRUM_SHARING]. The spectrum needs were analyzed and it was concluded that the additional allocation to the FSS being considered is beneficial to make broadband connections accessible to communities as achieved by HTS (High Throughput Satellite) systems. Additionally, the outcome of the studies has demonstrated the possibility of sharing and compatibility with the appropriate protection measures. Studies included sharing and compatibility between FSS and other primary services in the band, such as fixed service and mobile service (including IMT-2020). Studies were also performed for the protection of Earth Exploration-Satellite Service (EESS) and Space Research Service (SRS) allocated in adjacent bands. Studies have considered FSS earth stations as small as 4.5 m but analysis of the various studies demonstrates the feasibility to use smaller FSS earth stations, as low as 2.4 m, with minimal impact. Based on the results of the sharing and compatibility studies this proposal supports an allocation of the frequency band 51.4-52.4 GHz to the fixed-satellite service (Earth-to-space), limited to FSS gateway links for geostationary orbit use while protecting currently allocated services in the same frequency band and in adjacent bands as follows: To protect FS stations, separation distances up to 33 km are required when assuming flat terrain and a 4.5 m earth station which means that the distance can be reduced when real terrain is taken into consideration. In the case of a 2.4 m earth station, the only impacting parameter is the change in FSS antenna peak gain and the resulting change in the transmitter power spectral density (assuming a fixed EIRP density) leading to a separation distance of 35 km. Regarding the possible IMT-2020 applications of the MS in the same frequency band, the required separation distances between FSS earth stations and IMT base station and IMT user equipment are 260 and 330 meters, respectively. The protection of non-GSO EESS (passive) sensors operating in the frequency band 52.654.25 GHz can be achieved by limiting the FSS earth station unwanted emissions falling in the passive band. Regarding the protection of future GSO EESS (passive) sensors, a footnote in article 5 will require coordination between a FSS network and a notified GSO EESS network when the orbital separation between the GSO EESS space station and the FSS space station is less than 1.8 degrees. Regarding protection of EESS (passive) sensors, studies have demonstrated that the FSS earth station antenna size has only a minimal impact on the results. It is then proposed to consider FSS earth station size as small as 2.4 m.

The “some cases” in which satellite-to-satellite links are included in the FSS are not elaborated in either the Radio Regulations or associated ITU publications. Nevertheless, the possibility for satellite-to-satellite links within the FSS exists. This possibility seems particularly reasonable in cases where a link from a space station in non-geostationary satellite orbit (non-GSO) is being transmitted in the same general direction (e.g., Earth-to-space) within the receive beam of a higher-altitude geostationary-orbit (GSO) space station using technical parameters identical or substantially similar to transmitting FSS ground stations within that GSO space station receive beam. As reported by the Director of the Radiocommunication Bureau to the final CPM for WRC-19, since 2014, there have been 27 submissions of advance publication information for non-GSO satellite systems under No. 4.4 of the Radio Regulations specifying use by a non-allocated space service of frequency bands allocated to another space service. See Document CPM19-2/017, at Section 3.1.3.2 (Preliminary Draft Report of the Director to WRC-19 on Activities of the Radiocommunication Sector). Notification information was subsequently filed for frequency assignments to 3 of these systems. The Director’s draft report states that “[n]one of these frequency assignments was reported to the BR as causing harmful interference to any service of another administration.” Document CPM19-2/017, at Section 3.1.3.2 The challenge comes, as the Director of the Radiocommunication Bureau has acknowledged, in finding a path to recognition in the Radio Regulations for such uses, where possible, based on the technical conditions derived from ITU-R studies. Because frequency bands allocated to the fixed-satellite service are used for links between space stations and earth stations, it is necessary to analyze the use of the same bands for satellite-to-satellite links to ensure compatibility and avoid harmful interference. The sharing scenario is likely to differ as the orbital characteristics of the linked satellites vary. Preliminary ITU-R studies have identified factors to be considered in assessing the compatibility of non-GSO satellite-to-GSO satellite links, in the Earth-to-space direction, with other FSS operations and other services in the 27.5 – 30 GHz frequency band. Continued development and completion of these studies will permit the development of appropriate ITU-R regulatory text to define the cases in which such transmissions may be provided within the fixed-satellite service and/or the inter-satellite service, and allow for a determination of whether the recognition of compatible links can be made via appropriate modifications to the studied FSS allocations in Article 5.

Advances in satellite technologies are allowing a variety of new services including innovative broadband, video and mobile services covering all corners of the globe and providing service to places and regions not covered by traditional terrestrial services and that, accordingly, are missing out on the benefits of new and innovative telecommunications services. The fixed-satellite service can support a number of important public interest initiatives including tele-health, tele-education and public protection and disaster relief. Just to name a few examples, high throughput satellites are bringing broadband connectivity to rural and remote areas, thereby advancing countries’ broadband objectives. New state of the art satellites that provide next generation satellite broadband, high quality video programming (including 3D and 4K programming), or the mobile-satellite service using Ka-band frequencies have recently been launched or will be launched shortly. This is not by chance; the technological progress in radio communication enables the satellite industry to offer much more capacity today with much less spectrum. This applies to the fixed-satellite service whether operating in the geostationary or non-geostationary orbits. The satellite industry takes this development into account by using the most spectrum efficient technologies, including advances in spot-beam technologies and frequency re-use. In addition, for some satellite applications, such as gateways, sharing with Radiocommunication services could be more easily accomplished. However, even with this efficiency, demand for fixed-satellite service outpaces the spectrum available for this service today. Nonetheless, there is growing demand for fixed-satellite service, including broadband and data services which in many rural and remote locations are the only ways of receiving these important communication services,. Today, with C, Ku and Ka bands reaching capacity, satellite frequencies are heavily used and are nearing saturation for many applications. Therefore, Satellite operators are seeking access to additional fixed-satellite service spectrum to satisfy existing and anticipated requirements for existing and new services, including broadband services. In the North America, for instance, over one million and a half customers currently rely on satellite broadband services and that number is growing each day. The United States proposes the 37.5-39.5 GHz frequency band for reverse direction operations for gateway earth stations. Other services shall be taken into account and this analysis shall include the possibility of sharing with existing uses of the bands.

This need can be provided by aeronautical and maritime earth stations in motion (ESIM), communicating with GSO space stations in the Fixed Satellite Service (FSS). The availability of the bands 10.7-10.95 GHz, 11.2-11.45 GHz, and 12.75-13.25 GHz, allocated to the FSS, for the use by aeronautical and maritime ESIM would allow satellite network operators to provide additional capacity for the growing needs in this sector. The frequency band 12.75-13.25 GHz is allocated on a primary basis to the fixed, fixed-satellite (Earth-to-space) The use of the band 12.75-13.25 GHz (Earth-to-space) by geostationary-satellite systems in the fixed-satellite service is in accordance with the provisions of Appendix 30B according to No. 5.441. , and mobile services, and on a secondary basis to the Space research (deep space) (space-to-Earth) services. The frequency bands 10.7-10.95 GHz (space-to-Earth) and 11.2-11.45 GHz (space-to-Earth) are allocated on a primary basis to the fixed, fixed-satellite (space-to-Earth) The use of the bands 10.7-10.95 GHz (space-to-Earth) and 11.2-11.45 GHz (space-to-Earth) by geostationary-satellite systems in the fixed-satellite service is in accordance with the provisions of Appendix 30B according to No. 5.441. , and mobile services except aeronautical mobile. Currently, satellite networks operating in this frequency band can provide services with aeronautical and maritime ESIM only under No. 4.4, which requires the associated transmissions not to cause harmful interference to, and not to claim protection from harmful interference caused by, a station operating in accordance with the Radio Regulations. Given the growing need for connectivity for aviation and maritime, it is proposed to study the viability of allowing the operation of aeronautical and maritime ESIM communicating with GSO space stations in the FSS in the 10.7-10.95 GHz (space-to-Earth), 11.2-11.45 GHz (space-to-Earth), and 12.75-13.25 GHz (Earth-to-space), frequency bands, with the aim of developing regulatory means and associated conditions for this type of application.

ATTACHMENT ANNEX 2 TO RESOLUTION 804 (REV.WRC12) Template for the submission of proposals for agenda items Subject: Developing technical conditions and regulatory provisions and associated conditions that allow for the operation of aeronautical and maritime ESIM communicating with geostationary space stations in the FSS in the frequency bands 10.7-10.95 GHz (space-to-Earth), 11.2-11.45 GHz (space-to-Earth), and 12.75-13.25 GHz (Earth-to-space) Origin: United States of America Proposal: To consider the use of the frequency bands 10.7-10.95 GHz (space-to-Earth), 11.2-11.45 GHz (space-to-Earth), and 12.75-13.25 GHz (Earth-to-space) by aeronautical and maritime ESIM communicating with geostationary space stations in the fixed-satellite service in accordance with Resolution [USA/10/FSS 12.75-13.25 GHZ] (WRC-19). Background/reason: According to the provisions of the Radio Regulations, FSS satellite networks operating in the 12.75-13.25 GHz frequency band can only provide services to aeronautical and maritime ESIM under No. 4.4. This provision requires the associated transmissions not to cause harmful interference to, and not to claim protection from harmful interference caused by, a station operating according to primary or secondary frequency allocations. Previous WRCs have adopted provisions to allow aeronautical and maritime ESIM to communicate with GSO space stations in the FSS in certain FSS frequency allocations provided they meet the technical requirements of fixed-satellite earth stations and other associated provisions. It may therefore be feasible to allow aeronautical and maritime ESIM to communicate with geostationary space stations in the FSS operating in the frequency bands 10.7-10.95 GHz (space-to-Earth), 11.2-11.45 GHz (space-to-Earth), and 12.75-13.25 GHz (Earth-to-space), which would allow the provision of such services with additional regulatory certainty. This additional use will not impact the Appendix 30B allotments/assignments. The earth stations on aircraft, similar to any other earth station operating in Appendix 30B frequency assignments, are to be operated within the service area and with the characteristics notified for earth stations of the GSO FSS system (i.e. within the interference envelope established for earth stations of the GSO FSS system). Such operation therefore should not cause interference to other allotments/assignments of Appendix 30B. Radiocommunication services concerned: FSS, FS, MS and SRS (deep space) Indication of possible difficulties: None foreseen Previous/ongoing studies on the issue: Previous WRCs have adopted technical and regulatory provisions that allow earth stations on aircraft to communicate with GSO space stations in the FSS. These decisions were based on studies carried out by the ITU-R. One of the regional organizations of ITU-R Region 1 has conducted technical studies on introducing earth stations on aircraft in the 12.75-13.25 GHz band concluding with the derivation of a pfd mask to ensure the protection (long term and short-term criteria) of terrestrial FS stations from the aggregated interference from earth stations on aircraft communicating with GSO and non-GSO space stations in the FSS. The above can be taken into account as proof of concept regarding the potential use of the band under consideration by aeronautical ESIM. Studies to be carried out by: SG4 with the participation of: ITU-R Study Groups concerned: SG5 and SG7 ITU resource implications, including financial implications (refer to CV126): Minimal Common regional proposal: Yes/No Multicountry proposal: Yes/No Number of countries: Remarks _________________________ DOCUMENT WAC/092 (11.03.19) 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-97, the Earth exploration-satellite (passive) service was upgraded from secondary to primary status in Region 2. In the 1997-2000 study period leading up to WRC-2000, SG-4 and SG-7 examined the technical and regulatory issues associated with considering the possible worldwide allocation for the earth exploration-satellite (passive) and space research (passive) services in the band 18.6 - 18.8 GHz. At the time, the allocation for the Earth exploration-satellite (passive) service was on a primary basis in Region 2, but on a secondary basis in Regions 1 and 3. These studies, performed under agenda item 1.17 (WRC-2000) which led to the establishment of the current footnote No. 5.522B, did not provide consideration for all types of non-geostationary (non-GSO) satellite systems that could operate in this band. During the studies, only one non-GSO satellite system was planning to use this band above an altitude of 20,000 km. Accordingly, the constraint was imposed without appropriate consideration of non-GSO systems operating with an apogee below 20,000 km. Since there is a growing demand for Low Earth Orbit (LEO) and Medium Earth Orbit (MEO) global satellite broadband services, revisiting the studies performed in the band 18.6-18.8 GHz while taking into account the latest technology developments, could help facilitate the deployment of non-GSO systems operating with an apogee below 20,000 km.

ATTACHMENT PROPOSAL FOR FUTURE AGENDA ITEM FOR [XXX] Subject: Proposed Future WRC Agenda Item for WRC-2023 to consider the results of studies on the … Revision to footnote No. 5.522A and 5.522B and Radio Regulations Article 21 power flux density limits regarding non-geostationary Fixed-Satellite Service systems with an apogee below 20 000 km that operate in the 18.6-18.8 GHz (space-to-Earth) band Origin: United States of America Proposal: Examine revision of Radio Regulation footnote 5.522A and 5.522B and Article 21, Table 21-4 regarding expansion of regarding non-geostationary Fixed-Satellite Service systems with an apogee below 20 000 km that operate in the 18.6-18.8 GHz (space-to-Earth) band. Background/reason: At WRC-97, the Earth exploration-satellite (passive) service was upgraded from secondary to primary status in Region 2. In the 1997-2000 study period leading up to WRC-2000, SG-4 and SG-7 examined the technical and regulatory issues associated with considering the possible worldwide allocation for the earth exploration-satellite (passive) and space research (passive) services in the band 18.6 - 18.8 GHz. At the time, the allocation for the Earth exploration-satellite (passive) service was on a primary basis in Region 2, but on a secondary basis in Regions 1 and 3. These studies, performed under agenda item 1.17 (WRC-2000) which led to the establishment of the current footnote No. 5.522B, did not provide consideration for all types of non-geostationary (non-GSO) satellite systems that could operate in this band. During the studies, only one non-GSO satellite system was planning to use this band above an altitude of 20,000 km. Accordingly, the constraint was imposed without appropriate consideration of non-GSO systems operating with an apogee below 20,000 km. Since there is a growing demand for Low Earth Orbit (LEO) and Medium Earth Orbit (MEO) global satellite broadband services, revisiting the studies performed in the band 18.6-18.8 GHz while taking into account the latest technology developments, could help facilitate the deployment of non-GSO systems operating with an apogee below 20,000 km. Radiocommunication services concerned: Earth Exploration Satellite, Fixed, Mobile, Fixed-Satellite, Space research Indication of possible difficulties: None foreseen Previous/ongoing studies on the issue: Studied in the 1997-2000 preparatory cycle leading up to WRC-2000 considering an allocation to EESS (passive) and SRS (passive). Studies to be carried out by: ITU-R Study Group 4 with the participation of: ITU-R Study Groups concerned: SG 5 and SG 7 ITU resource implications, including financial implications (refer to CV126): Minimal Common regional proposal: No Multicountry proposal: No Number of countries: One Remarks _______________________ DOCUMENT WAC/093 (11.03.19) 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: Non-geostationary (“NGSO”) satellite constellations in frequency bands 17.7-20.2 GHz (space-to-Earth) and 27.5-30 GHz (Earth-to-space) enable the provision of Internet connectivity and more of such NGSO systems offering broadband solutions are planned to be deployed in the near future in the same bands and in the 37.5-39.5 GHz (space-to-Earth), 39.5-42.5 GHz (space-to-Earth), 47.2-50.2 GHz (Earth-to-space) and 50.4-51.4 GHz (Earth-to-space). These constellations are designed to meet the consumer demand for access to broadband connectivity, regardless of location. One area of noticeable growth for NGSO connectivity is for earth stations in motion (“ESIM”). This market segment is particularly well served by satellites and in instances where lower latency matters, NGSO connectivity is there to deliver. For example, there is growing demand for high performance connectivity for users on maritime vessels and aircraft, as well as for other applications at both fixed locations and while in motion. New and next generation NGSO systems will be designed to serve smaller ESIM terminals and as such NGSO systems offer the potential to expand connectivity to new market segments rapidly. In order to facilitate the further deployment of ubiquitous broadband connectivity to ESIM services in the above mentioned frequency bands, there should be consideration on how to develop internationally harmonized spectrum technical and regulatory measures or frameworks that will enable and facilitate deployment of this critical and valuable service using NGSO satellites. It is proposed to carry out technical sharing studies between all types of ESIM communicating with NGSO FSS systems with other primary services in the frequency bands 17.7-20.2 GHz (space-to-Earth), 27.5-30.0 GHz (Earth-to-space), 37.5-39.5 GHz (space-to-Earth), 39.5-42.5 GHz (space-to-Earth), 47.2-50.2 GHz (Earth-to-space) and 50.4-51.4 GHz (Earth-to-space), in order to develop appropriate technical and regulatory requirements (which may include, but not limited to, off-axis EIRP density limits, minimum antenna elevation angles and power-flux densities) to facilitate the operations of such earth stations, while ensuring harmful interference is not caused to other primary services. This proposal does not call for the revision of the epfd limits in Article 22 of the Radio Regulations for the frequency bands of 17.8-18.6 GHz, 19.7-20.2 GHz (space-to-Earth) / 27.5-28.6 GHz, 29.5-30 GHz (Earth-to-space) and 17.8-18.4 GHz (inter-satellite) nor any provisions established by WRC-19 in consideration of Resolution 159 (WRC-15). In studying the frequencies 29.1-29.5 GHz for use by FSS NGSO ESIMs, it is necessary to first study the technical and regulatory measures necessary to allow other uses by FSS NGSO satellite systems not limited to MSS feeder links, subject to provision No. 22.2.

ATTACHMENT ANNEX 2 TO RESOLUTION 804 (REV.WRC12) Template for the submission of proposals for agenda items PROPOSAL FOR FUTURE AGENDA ITEM FOR [XXX] Subject: Proposed Future WRC Agenda Item for WRC-2023 to consider the results of studies on NGSO ESIM in the frequency bands 17.7-20.2 GHz (space-to-Earth), 27.5-30.0 GHz (Earth-to-space), 37.5-39.5 GHz (space-to-Earth), 39.5-42.5 GHz (space-to-Earth), 47.2-50.2 GHz (Earth-to-space) and 50.4-51.4 GHz (Earth-to-space) Origin: United States of America Proposal: Study and develop technical and regulatory measures or frameworks, as appropriate, to facilitate the use of the frequency bands 17.7-20.2 GHz (space-to-Earth), 27.5-30.0 GHz (Earth-to-space), 37.5-39.5 GHz (space-to-Earth), 39.5-42.5 GHz (space-to-Earth), 47.2-50.2 GHz (Earth-to-space) and 50.4-51.4 GHz (Earth-to-space) by NGSO ESIM. In studying the use of the frequency band 29.1-29.5 GHz by fixed-satellite service (FSS), it is necessary to study the technical and regulatory measures to allow other uses of these frequencies by NGSO satellite systems. Background/reason: Non-geostationary (“NGSO”) satellite constellations in frequency bands 17.7-20.2 GHz (space-to-Earth) and 27.5-30 GHz (Earth-to-space) enable the provision of Internet connectivity and more of such NGSO systems offering broadband solutions are planned to be deployed in the near future in the same bands and in the 37.5-39.5 GHz (space-to-Earth), 39.5-42.5 GHz (space-to-Earth), 47.2-50.2 GHz (Earth-to-space) and 50.4-51.4 GHz (Earth-to-space). These constellations are designed to meet the consumer demand for access to broadband connectivity, regardless of location. One area of noticeable growth for NGSO connectivity is for earth stations in motion (“ESIM”). This market segment is particularly well served by satellites and in instances where lower latency matters, NGSO connectivity is there to deliver. For example, there is growing demand for high performance connectivity for users on maritime vessels and aircraft, as well as on for other applications at both fixed locations and while in motion. New and next generation NGSO systems will be designed to serve smaller ESIM terminals and as such NGSO systems offer the potential to expand connectivity to new market segments rapidly. In order to facilitate the further deployment of ubiquitous broadband connectivity to ESIM services in the above mentioned frequency bands, there should be consideration on how to develop internationally harmonized spectrum technical and regulatory measures or frameworks that will enable and facilitate deployment of this critical and valuable service using NGSO satellites. It is proposed to carry out technical sharing studies between all types of ESIM communicating with NGSO FSS systems with other primary services in the frequency bands 17.7-20.2 GHz (space-to-Earth), 27.5-30.0 GHz (Earth-to-space), 37.5-39.5 GHz (space-to-Earth), 39.5-42.5 GHz (space-to-Earth), 47.2-50.2 GHz (Earth-to-space) and 50.4-51.4 GHz (Earth-to-space), in order to develop appropriate technical and regulatory requirements (which may include, but not limited to, off-axis EIRP density limits, minimum antenna elevation angles and power-flux densities) to facilitate the operations of such earth stations, while ensuring harmful interference is not caused to other primary services. This proposal does not call for the revision of the epfd limits in Article 22 of the Radio Regulations for the frequency bands of 17.8-18.6 GHz, 19.7-20.2 GHz (space-to-Earth) / 27.5-28.6 GHz, 29.5-30 GHz (Earth-to-space) and 17.8-18.4 GHz (inter-satellite) nor any provisions established by WRC-19 in consideration of Resolution 159 (WRC-15). In studying the frequencies 29.1-29.5 GHz for use by FSS NGSO ESIMs, it is necessary to first study the technical and regulatory measures necessary to allow other uses by FSS NGSO satellite systems not limited to MSS feeder links, subject to provision No. 22.2. Radiocommunication services concerned: Fixed, Mobile, Inter-Satellite, Broadcasting-satellite, MSS, FSS, Space Research (passive) and EESS (passive) Indication of possible difficulties: Technical and regulatory requirements too stringent to allow an efficient deployment of ESIM services. Previous/ongoing studies on the issue: Technical and operational requirements for ESIM (which were referred to as earth stations on mobile platforms (“ESOMPs”) prior to WRC-15) operating with NGSO FSS systems in the frequency bands 17.3-20.2 GHz, 27.5-29.1 GHz and 29.5-30.0 GHz have been discussed in the ITU-R and are reflected in the Report ITU-R S.2261. The Report identified the technical and operational requirements to be considered with the deployment of ESOMPs operating with NGSO FSS systems in the frequency bands 17.3-19.3 GHz, 19.7-20.2 GHz, 27.0-29.1 GHz and 29.5-30.0 GHz. The Report describes how ESOMPs operating in these frequency bands must be designed and operated to meet the existing technical and/or operational requirements applicable to FSS earth stations. Studies to be carried out by: ITU-R Study Group 4 with the participation of: ITU-R Study Groups concerned: SG-5 and SG 7 ITU resource implications, including financial implications (refer to CV126): minimal Common regional proposal: Yes/No Multicountry proposal: Yes/No Number of countries: Remarks ___________________________ DOCUMENT WAC/094 (11.03.19) 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, in accordance with Article 7 of the Convention; BACKGROUND INFORMATION: WRC-97 adopted 5.523A whereby the use of certain frequency bands by geostationary and non-geostationary fixed satellite service networks is subject to the application of the provisions of No. 9.11A and No. 22.2 does not apply. This WRC action allows non-GSO satellite systems to operate in the bands referred to in 5.523A subject to coordination on a first come first served basis with respect to GSO satellite networks. WRC-97 also adopted provisional equivalent pfd (epfd) and aggregate epfd limits to be met by NGSO satellite systems operating in certain frequency bands. WRC-2000 adopted definitive epfd limits and expanded the ranges of frequency where they would apply. A NGSO satellite system meeting the epfd limits in the relevant frequency bands is deemed to be compliant with Article 22.2 with respect to any GSO satellite network regardless of priority date. WRC-19 will review the results of the studies and will consider taking appropriate regulatory actions for non-GSO satellite systems in the 37-51.4 GHz frequency range by adopting aggregate criteria not to be exceeded by non-GSO FSS systems in order to protect GSO FSS and GSO BSS networks against interference. High mm-wave bands are particularly suitable for use as ultra-high capacity gateway links for large constellation non-GSO FSS systems using broadband service links. In addition, these frequency bands are potentially suitable for broadband links for consumer and enterprise customers. As a result, system trials of high mm-wave bands are progressing and technology prototypes are maturing. However, there are currently no mechanisms in the RR establishing coordination procedures applicable between NGSO systems, nor methods of ensuring satisfactory co-existence with GSO networks, operating in the frequency bands currently allocated to the FSS in the range from 71-76 GHz (space-to-Earth) and 81-86 GHz (Earth-to-space). This contributes to uncertainty with adopting high mm-wave gateway technology among potential operators of non-GSO satellite systems in these bands, which should be addressed by a competent WRC.

l) that the Radio Regulations should enable the introduction of new applications of radiocommunication technology to ensure the operation of as many systems as possible in order to ensure efficient use of the spectrum; m) that, unacceptable interference as per No. 22.2 is subject to interpretation and the performance and interference criteria of GSO and non-GSO links have not been established in these bands; n) that technical studies are required in order to ascertain the feasibility of, and conditions for, non-GSO FSS satellite systems sharing the frequency bands 71-76 GHz and 81-86 GHz as appropriate to the band), and 2) with other non-GSO FSS satellite systems;

Radiocommunication services concerned: Earth Exploration Satellite, Space research, Radio Astronomy, Fixed, Mobile, Fixed-Satellite Indication of possible difficulties: None foreseen Previous/ongoing studies on the issue: a) Studied in the 2015-2019 preparatory cycle leading up to WRC-2019 considering to adopt provisions to quantify No. 22.2, in order to establish protection of GSO FSS and BSS satellite networks from non-GSO FSS satellite systems in the 37-51.4 GHz frequency range; b) Studied in the 2015-2019 preparatory cycle leading to a Report ITU-R S.[E-band FSS characteristics] currently being developed to provide additional system characteristics of planned high mm-wave FSS network and systems Studies to be carried out by: ITU-R Study Group 4 with the participation of: ITU-R Study Groups concerned: SG 5 and SG 7 ITU resource implications, including financial implications (refer to CV126): Minimal Common regional proposal: No Multicountry proposal: No Number of countries: One Remarks __________________ DOCUMENT WAC/097 (11.03.19) Comments of IWG-4 on NTIA Agenda Item 10 Proposal in Doc. IWG-4/056 United States PROPOSALS FOR THE WORK OF THE CONFERENCE Agenda item 10 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 The 2007 World Radiocommunication Conference (WRC-07) modified Appendix 4 Annex 2 of the Radio Regulations to allow the characteristics of active and passive sensors to be filed in the ITU-R under the provisions of Articles 9 and 11 so they may be recorded in the Master International Frequency Register. Any frequency assignment recorded in the Master Register with a favourable finding under No. 11.31 shall have the right to international recognition. For such an assignment, this right means that other administrations shall take it into account when making their own assignments, in order to avoid harmful interference. (RR No. 8.3) Nevertheless, Nos. 5.28 to 5.31 place the conditions imposed on secondary services with regard to causing or claiming protection from harmful interference from other services. It is noted that passive remote sensors are detecting an increasing number of instances of interference events and the interference is distributed worldwide. Procedures are contained in Section VI of Article 15 to address the actions to be taken when harmful interference occurs between networks authorized by different Administrations. In particular, No. 15.27 states full particulars relating to harmful interference shall, whenever possible, be given in the form indicated in Appendix 10. As Appendix 10 was designed with terrestrial radiocommunication services in mind, its applicability related to harmful interference detected by EESS (passive) sensors is very limited. Passive sensors have unique characteristics to detect the particulars of the interference using different parameters from those of stations used for radiocommunication. Administrations have approved Recommendation ITU-R RS.2106-0 which provides data fields which should be used for reporting, detection and resolution of radio frequency interference to Earth exploration-satellite service (passive) sensors.

X.X1 to consider modifying RR Appendix 10 to improve the reporting and resolution of interference to Earth exploration-satellite service passive sensors in accordance with Resolution YYY (WRC-19), and without modification to the procedure for cases of harmful interference in Section VI of Article 15 of the Radio Regulations; Reasons: To establish a form suitable for the reporting of cases of harmful interference to Earth exploration-satellite service passive sensors which is not currently available through the existing provisions of the Radio Regulations ADD TBD/XXX/2 DRAFT NEW RESOLUTION [YYY] (WRC-19) Reporting of harmful interference to passive sensors in the Earth exploration-satellite service The World Radiocommunication Conference (Sharm el-Sheikh, 2019), considering a) that passive sensors provide information critical to maintaining and improving the accuracy of weather forecasts and climate models, which contribute to the protection of life and preservation of property throughout the world; b) that, in many cases, the frequencies used by Earth exploration-satellite service (passive) sensors are chosen to study natural phenomena producing radio emissions at frequencies determined by the laws of nature, and therefore shifting frequency to avoid or mitigate interference problems is not possible; c) that some passive remote sensor operations in some frequency bands are impaired by an increasing number of cases of interference, recognizing a) that Section VI of Article 15 of the Radio Regulations describes the procedure for the resolution of cases of harmful interference; b) that under No. 15.27, full particulars relating to harmful interference shall, whenever possible, be given in the form indicated in Appendix 10 to the Radio Regulations; c) that the applicability of the form in Appendix 10 to harmful interference detected by EESS (passive) sensors is very limited, further recognizing that Recommendation ITU-R RS.2106-0 “Detection and resolution of radio frequency interference to Earth exploration-satellite service (passive) sensors” provides a reporting form for recording and reporting the radio frequency interference to Earth exploration-satellite service (passive) sensors, noting a) that under RR No. 4.7 for the purpose of resolving cases of harmful interference, the earth exploration-satellite (passive) service shall be afforded protection from different services in other bands only to the extent that these different services are protected from each other; b) that RR Nos. 5.28 to 5.31 define the conditions imposed on secondary services with regard to causing or claiming protection from harmful interference from other services, resolves to invite the ITU-R to conduct and complete, in time for WRC-23, ITU-R technical and regulatory studies appropriate to developing a form suitable for reporting cases of harmful interference to passive sensors that can be used in the procedure for the resolution of cases of harmful interference in Section VI of Article 15 of the Radio Regulations, without modification to Article 15, invites the 2023 World Radiocommunication Conference to take into account the results of ITU-R studies in resolves to invite the ITU-R, and consider the possibility of including within Appendix 10 a form or forms suitable for reporting cases of harmful interference to passive sensors invites administrations to participate actively in the studies by submitting contributions to ITU-R, instructs the Secretary-General to bring this Resolution to the attention of the World Meteorological Organization (WMO) and other international and regional organizations concerned. Reasons: A resolution will support the ITU-R studies needed under the relevant WRC-23 agenda item. SUP TBD/XXX/3 RESOLUTION 810 (WRC15) Preliminary agenda for the 2023 World Radiocommunication Conference Reasons: This Resolution must be suppressed, as WRC-19 will create a new Resolution that will include the agenda for WRC-23. 46 ATTACHMENT PROPOSAL FOR ADDITIONAL AGENDA ITEM TO CONSIDER IMPLEMENTING A MECHANISM IN RR APPENDIX 10 TO IMPROVE THE REPORTING AND RESOLUTION OF INTERFERENCE TO EARTH EXPLORATION-SATELLITE SERVICE PASSIVE SENSORS Subject: Proposed future WRC agenda item for WRC-23 to consider the processes for reporting and resolving harmful interference to passive sensors Origin: [TBD] Proposal: To consider implementing a mechanism in RR Appendix 10 to improve the reporting and resolution of interference to Earth exploration-satellite service passive sensors in accordance with Resolution YYY (WRC-19). Background/reason: Procedures are contained in Section VI of Article 15 to address the actions to be taken when harmful interference occurs between networks authorized by different Administrations. In particular, RR No. 15.27 states full particulars relating to harmful interference shall, whenever possible, be given in the form indicated in Appendix 10. As Appendix 10 was designed with terrestrial radiocommunication services in mind, its applicability related to harmful interference detected by EESS (passive) sensors is very limited. Passive sensors have unique characteristics to detect the particulars of the interference using different parameters from those of stations used for radiocommunication. The ITU-R has approved Recommendation ITU-R RS.2106 which provides data fields which should be used for the detection and resolution of radio frequency interference to Earth exploration-satellite service (passive) sensors. Radiocommunication services concerned: Earth exploration-satellite service, fixed service, mobile service Indication of possible difficulties: None foreseen Previous/ongoing studies on the issue: ITU-R WP 7C has already developed Recommendation ITU-R RS.2106-0, Detection and resolution of radio frequency interference to Earth exploration-satellite service (passive) sensors Studies to be carried out by: WP 7C with the participation of: ITU-R Study Groups concerned: SG 1, SG 5 ITU resource implications, including financial implications (refer to CV126): Minimal Common regional proposal: Yes/No Multicountry proposal: Yes/No Number of countries: Remarks ______________
