8 APG Structure for WRC-07 and Preliminary Views (as at APG2007-3)

9 APT Conference Preparatory Group for WRC (APG) APT assigned WRC-07 Agenda Items to the Working Parties (WPs) to reflect the CPM-06 Chapter structure WP1: Mobile, aeronautical, radio navigation and radiolocation services –WRC-07 Agenda Items 1.3, 1.4, 1.5 and 1.6 (CPM-06 Chapter 1) – APG Output document APG2007-3/147 (Rev.1) available from: 3/Documents/APG2007-3DocList.htmAPG2007-3/147 (Rev.1) 3/Documents/APG2007-3DocList.htm

10 APT Preliminary Views for WRC (as at APG2007-3) Agenda Item 1.3 – Primary RLS MHz and MHz and 200 MHz for EESS and SRS above or below MHz Bands used internationally for aeronautical radionavigation including airborne weather radar, precision approach radar, surface movement radar and Airport Surface Detection Equipment Also used for Govt (radiolocation) & Maritime (radionavigation) radars Aeronautical radionavigation ground- based radars critical to airport ops during poor weather. Standard & mandated aircraft weather radar for Regular Passenger Transport (RPT) aircraft in many countries. Safety of life aspects, careful consideration required so that the use and development of the radionavigation service is not interfered with or constrained.

11 APT Preliminary Views for WRC (as at APG2007-3) Agenda Item 1.3 – Primary RLS MHz and MHz and 200 MHz for EESS and SRS above or below MHz a. Upgrading of radiolocation APT Administrations are of the view that the upgrading of radiolocation service to primary would be supported, subject to agreed ITU-R studies indicating that sharing with the radionavigation service is possible. These studies to be done by ITU-R needs to take into account measurement tests. It is also required that the radiolocation service operating in the MHz and MHz bands should not cause harmful interference to, nor claim protection from, the radionavigation service, operating in accordance with the Radio Regulations. This could be accomplished by an appropriate footnote to protect the aeronautical radionavigation and radionavigation systems. One Administration is considering if this or another method would best achieve its objectives.

12 APT Preliminary Views for WRC (as at APG2007-3) Agenda Item 1.3 – Primary RLS MHz and MHz and 200 MHz for EESS and SRS above or below MHz b. The extension of EESS and Space Research Service by 200 MHz APT Members are of the view that they support ongoing ITU-R compatibility studies between the existing systems operating in the radiolocation and radionavigation services in the – MHz band and the spaceborne radar systems operating under EESS (active) and SRS (active). Any expansion of the EESS (active) and SRS (active) allocation beyond the band MHz should ensure that the incumbent services are protected. Should an expansion be granted to the EESS (active) and SRS (active) to operate spaceborne radar, some APT Administrations consider at this time that the lower portion ( MHz) are preferable due to the fact that the band MHz, fixed systems are operating or planned to be operated in some APT Administrations. Necessary regulatory text will be required to ensure protection to incumbent services.

13 APT Preliminary Views for WRC (as at APG2007-3) Agenda Item 1.5 – to consider spectrum requirements and possible additional spectrum allocations for aeronautical telecommand and high bit-rate aeronautical telemetry, in accordance with Resolution 230 (WRC 03) Spectrum required for Unmanned Aerial Vehicles (UAV), flight testing of modern aircraft and other civil and Govt aerospace platforms Studies focusing on short/medium term below 16 GHz and long term below 30 GHz (technology constraints) Bands being studied MHz, MHz, MHz, MHz, GHz, GHz and GHz

14 APT Preliminary Views for WRC (as at APG2007-3) Agenda Item 1.5 – to consider spectrum requirements and possible additional spectrum allocations for aeronautical telecommand and high bit-rate aeronautical telemetry, in accordance with Resolution 230 (WRC 03) a. APT Administrations support the studies under Resolution 230 (WRC–03) into the requirements for justifiable wideband aeronautical mobile telemetry (AMT) and associated telecommand spectrum above 3 GHz, and notes that considering (d) of this Resolution identifies a need to protect existing services. These studies will need to take into account: a)the bandwidth demand for wideband AMT and associated telecommand; and b)where appropriate, existing ARNS and FSS allocations, including the existing and planned usage by each service; and c)possible developments under Agenda item 1.6 (Resolution 414 (WRC–03)) in the MHz and other aeronautical radionavigation bands between 3 and 6 GHz. Any allocation to AMT in an ARNS or AM(R)S band should be conditional upon the completion of rigorous and conclusive ITU-R studies first which demonstrate that sharing will not have any implications for the safety of operations of affected aviation systems. In these studies all bands above 3 GHz should be considered under Resolution 230 (WRC-03), including possible additional allocations under Resolves 3, unless completed ITU-R studies show that it is not possible to use those particular bands for wideband AMT and associated telecommand.

15 APT Preliminary Views for WRC (as at APG2007-3) Agenda Item 1.5 – to consider spectrum requirements and possible additional spectrum allocations for aeronautical telecommand and high bit-rate aeronautical telemetry, in accordance with Resolution 230 (WRC 03) b. Regarding the resolve 4, APT could support to give a priority to the designation of frequency bands already allocated to mobile service between 16 and 30 GHz for wideband aeronautical telemetry and associated telecommand on a primary basis. Any action in regard to this agenda item must take into account the existing services to which this frequency band is allocated and fully protect them. Appropriate revision/modification of footnotes to The Table of Frequency Allocations, Article 5 RR, might be required (i.e , 5.343, 5.348B, 5.394, 5.395). Frequency band – MHz Study the feasibility of co-band sharing of AMT and incumbent radio services in the bands MHz and MHz Frequency bands above 6 GHz Study the feasibility of wideband aeronautical telemetry and associated telecommand using the bands GHz, GHz and GHz. Support the designation of frequency bands already allocated to mobile service between 16 and 30 GHz for wideband aeronautical telemetry and associated telecommand on a primary basis.

16 APT Preliminary Views for WRC (as at APG2007-3) Agenda Item 1.6 – to consider additional allocations for the aeronautical mobile (R) service in parts of the bands between 108 MHz and 6 GHz, in accordance with Resolution 414 (WRC 03) –VHF congestion (Europe and USA) and new ATM and Aeronautical operation control (AOC) requirements VHF comms band nearing saturation even with 8.33 kHz channelling ATM: increased use of datalinks - air-derived data, separation and self- separation of aircraft AOC: Dispatch, Flight Planning, and other airline operational comms – Airport Wireless and Security Applications High integrity WLANs with connected grids of distributed sensors - reduce runway incursions, increased comms capacity at airports secure air-ground radio link with key security information in encrypted form to decision-makers –UAT requires AM(R)S allocation –UAV telemetry/telecommand links for safety and regularity of flight

17 APT Preliminary Views for WRC (as at APG2007-3) Agenda Item 1.6 – to consider additional allocations for the aeronautical mobile (R) service in parts of the bands between 108 MHz and 6 GHz, in accordance with Resolution 414 (WRC 03) a. APT Administrations support global allocations to the aeronautical mobile (R) service in the frequency bands MHz and MHz if shown to meet global CNS/ATM requirements and future trends on the basis of compatibility with the existing services and it cannot operate in existing aeronautical mobile (R) spectrum. In the MHz band compatibility will be required with FSS Earth-to-space feeder links. Some Administrations in APT has operational feeder links in this band. It is also recognized that there is a need to maintain compatibility with services in adjacent bands. In particular, any allocation changes in the MHz band must be compatible with terrestrial broadcasting systems and place no additional constraints on the broadcasting service in the band MHz.

18 APT Preliminary Views for WRC (as at APG2007-3) Agenda Item 1.6 – to consider additional allocations for the aeronautical mobile (R) service in parts of the bands between 108 MHz and 6 GHz, in accordance with Resolution 414 (WRC 03) b. The frequency band MHz is allocated to RNSS and is either currently used or is to be used by some systems. If this band were to be considered for the provision of AM(R)S services it has to be ensured that it does not place any additional constraint on RNSS systems. In the event that spectrum is made available for use by UAVs, APT Administrations are of the view that appropriate spectrum should also be made available for telecommand purposes to facilitate the safe operation of UAVs, subject to not adversely affecting existing or planned services. One Administration also supports a global allocation to the aeronautical mobile (R) service in the frequency bands MHz. Another Administration does not support the allocation of the aeronautical mobile (R) service to MHz due to its extensive use of this band for Distance Measuring Equipment (DME).

19 APT Preliminary Views for WRC (as at APG2007-3) Agenda Item 1.6 – to study current satellite frequency allocations, that will support the modernization of civil aviation telecommunication systems, taking into account Resolution 415 (WRC 03) –Proposed by Kenya and Uganda as a method of improving developing countries CNS/ATM aviation infrastructure by reducing reliance on expensive and unreliable terrestrial systems –Studies considering the recognition of satellite communication systems such as VSAT for aeronautical safety applications –Also a proposal for an AMSS (s-E) secondary allocation to compliment the existing AMSS (E-s) secondary allocation in the band GHz. Not intended for aeronautical SOL communications

20 APT Preliminary Views for WRC (as at APG2007-3) Agenda Item 1.6 – to study current satellite frequency allocations, that will support the modernization of civil aviation telecommunication systems, taking into account Resolution 415 (WRC 03) a. APT Administrations are of view that 1.existing Fixed Satellite Service (FSS) spacecraft and appropriate earth stations can be used to create, augment or enhance infrastructure to support civil aviation telecommunications services, including ICAO CNS/ATM applications. 2.the use of satellite-based facilities in connection with civil aviation applications will contribute to the overall improvement of the aviation communications infrastructure in developing countries and remote areas. However, it should be ensured that these applications are consistent with existing satellite frequency allocations. 3.guidance material in the form of an ITU-R Recommendation or handbook should be prepared detailing the spectrum management issues associated with using VSAT networks for aeronautical telecommunication applications, noting that this spectrum may also support other non-aviation users.

21 APT Preliminary Views for WRC (as at APG2007-3) Agenda Item 1.6 – to study current satellite frequency allocations, that will support the modernization of civil aviation telecommunication systems, taking into account Resolution 415 (WRC 03) b. One Administration expressed their support to the allocation of the following bands for the use of the aeronautical mobile-satellite service on a secondary basis: Region 1: GHz and GHz (s-E) Region 2: GHz (s-E) Region 3: GHz and GHz (s-E), as the companion downlink allocation to the existing AMSS uplink allocation in the band GHz, providing such allocation does not have any adverse impact on existing services in these bands. This allocation is not intended to be used for aeronautical safety-of-life ICAO CNS/ATM communications. One Administration expressed different view that does not support the opening of the issue relating to the secondary 14 GHz uplink allocation to AMSS adopted by WRC-03. Such allocation to the uplink AMSS was done with considerable difficulties at WRC-03 under Agenda Item 1.11 of the Conference. Now that, by a way of consensus, the uplink allocation is made, we do not support any argument that one needs to allocate a secondary downlink at GHz to complement the above-mentioned uplink. The agreement reached at WRC-03 for the uplink on 14 GHz, secondary basis, was on the assumption that its associated downlink would operate under RR 4.4.

22 APT Preliminary Views for WRC (as at APG2007-3) Agenda Item 1.4 – to consider frequency-related matters for the future development of IMT 2000 and systems beyond IMT 2000 taking into account the results of ITU R studies in accordance with Resolution 228 (Rev.WRC 03); An extract … APT administrations are of the view that the bands currently allocated to aeronautical mobile (R) services and aeronautical radio determination services related to safety of life should not be identified for use for IMT applications.

23 APT Conference Preparatory Group for WRC (APG) Next APG2007 Meeting APG scheduled for 8-12 January 2007, Bangkok, Thailand. Will concentrate on assessing the draft WRC-07 Conference Preparatory Meeting (CPM) text based on the results of completed ITU-R studies. Based on the methods proposed in the draft CPM text preliminary common APT positions will be updated and proposals developed for the CPM meeting in March 2007.
