  16. Preparation of CPM Report

  17. Part of CPM Report Agenda Items 1.3, 1.4, 1.5, 1.6 Chapter 1 Chapter 2 1.2, 1.20, 1.21 1.7, 1.9, 1.11, 1.17 Chapter 3 Chapter 4 1.8, 1.18, 1.19 1.13, 1.14, 1.15, 1.16 Chapter 5 1.10, 1.12, 7.1 Chapter 6 2, 4, 5, 6, 7.1, 7.2 Chapter 7 Structure and Contents of CPM Report • Mobile, aeronautical mobile, radionavigation and radiolocation services • Space science services • FSS, MSS and BSS below 3 GHz • Fixed service including HAPS and FSS above 3 GHz • Services in LF, MF and HF bands and maritime mobile service • Regulatory procedures and associated technical criteria applicable to satellite networks • Future WRC programmes and other issues

  18. Chapter 2 of CPM Report WRC-07 Agenda items • Space science services • Rapporteur: Mrs. Shayla Taylor (USA) 1.2, 1.20, 1.21 • 1.2: Allocations and related regulatory issues for EESS (passive), SRS (passive) and Meteo-Sat in 18.1 – 18.4 GHz, 10.6 – 10.68 GHz and 36 – 37 GHz • 1.20: Protection of EESS (passive) (bands 1400 – 1427 MHz, 23.6 – 24 GHz, 31.3 – 31.5 GHz, 50.2 – 50.4 GHz) from unwanted emissions of active services • 1.21: Compatibility between RA and active space services (bands referred to in Res740) in order to review and update the threshold levels used for consultation (Annex to Res739)

  19. AI 1.2: Allocations and related regulatory issues for EESS (passive), SRS (passive) and MetSat in 18.1–18.4 GHz, 10.6–10.68 GHz and 36–37 GHz (1) • Current results of studies (18.1-18.4 GHz): • the addition of 100 MHz seems feasible under certain conditions (but compatibility between MetSat and NGSO FSS not studied); • proposes additional allocation, either 18.0-18.1 or 18.3-18.4 GHz; • indication that 18.0-18.1 GHz option may impose minor constrains on MetSat orbital positions due to operation of BSS feeder-links of networks belonging to Regions 1 and 3 BSS Plans/Lists (Appendix 30A)

  20. AI 1.2: Allocations and related regulatory issues for EESS (passive), SRS (passive) and MetSat in 18.1–18.4 GHz, 10.6–10.68 GHz and 36–37 GHz (2) • Current results of studies (10.6-10.68 GHz and 36-37 GHz): • interference from FS in 10.6-10.68 GHz band may exceed limits for EESS sensors by ~17 dB; mitigation therefore necessary; • preliminary sharing criteria proposed for 36-37 GHz band, but not to be applied to terrestrial systems brought into use before WRC-07

  21. AI 1.20: Protection of EESS (passive) (bands 1400 – 1427 MHz, 23.6 – 24, 31.3 – 31.5, 50.2 – 50.4 GHz) from unwanted emissions of active services • Current results of studies: • TG 1/9 revising Rec. ITU-R SM.1633, which should be used as a basis for developing EESS protection criteria; • proposed to include unwanted emission power [limit /level] in RR; sensors protected but some limitation on future active systems; • still at a preliminary stage.

  22. AI 1.21: Compatibility between RA and active space services (Res.740) in order to review and update threshold levels used for consultation (Annex to Res.739) • Current results of studies: • proposed PFD threshold levels for RAS protection from interference from different services; • 3 methods are under consideration: • 1st –add approved thresholds in Res.739 and apply them (RAS protected, but more work for ADMs due consultation); • 2nd similar to 1st but RNSS is not covered (no burden for ADMs but RAS may not be protected in 1559-1610 MHz); • 3rd no incorporation of thresholds (TBD).

  23.
