  6. Agenda Item 1.6 - (3) Resolution 950 (Rev.WRC‑07) : Consideration of the use of the frequencies between 275 and 3 000 GHz resolves • to review No. 5.565 of the Radio Regulations, excluding frequency allocations, in order to update the spectrum use between 275 GHz and 3 000 GHz by the passive services at WRC‑11, taking into account the result of the ITU-R studies; • that administrations may submit for inclusion in the Master International Frequency Register details on systems which operate between 275 and 3 000 GHz and which may be recorded by the Radiocommunication Bureau under Nos. 8.4, 11.8 and 11.12, invites ITU‑R to conduct the necessary studies in time for consideration by WRC‑11 with a view to the modification of No. 5.565, including advice on the applications suitable for the band 275‑3 000 GHz,

  7. Agenda Item 1.6 – RR 5.565 Related footnote RR5.565  The frequency band 275-1000 GHz may be used by administrations for experimentation with, and development of, various active and passive services. In this band a need has been identified for the following spectral line measurements for passive services:  Radio astronomy service : 275-323 GHz, 327-371 GHz, 388-424 GHz, 426-442 GHz, 453-510 GHz, 623-711 GHz, 795-909 GHz and 926-945 GHz  Earth exploration-satellite service (passive) and space research service (passive) : 275-277 GHz, 294-306 GHz, 316-334 GHz, 342-349 GHz, 363-365 GHz, 371-389 GHz, 416-434 GHz, 442-444496-506 GHz, 546-568 GHz, 624-629 GHz, 634-654 GHz, 659-661 GHz, 684-692 GHz, 730-732 GHz, 851-853 GHz and 951-956 GHz

  8. Agenda Item 1.6 - (4) Resolution 955 (Rev.WRC‑07) : Consideration of procedures for free‑space optical links resolves • to consider possible procedures for free-space optical links, taking into account the results of ITU-R studies covering at least sharing aspects with other services, a clear definition of the band limits and measures to be considered if allocations to various services in the Radio Regulations above 3 000 GHz are considered feasible, invites ITU‑R to conduct the necessary studies in time for consideration by WRC‑11.

  9. Agenda Item 1.6 – (5) Related ITU-R Recommendation ITU-R RS.1804 (Technical and operational characteristics of Earth exploration-satellite service (EESS) systems operating above 3 000 GHz) (2007) recommends • that operators of EESS systems operating above 3 000 GHz should take into account the possibility of interference from transmitters of the science services (including those of EESS) in their selection of mission requirements and choices of sensor design; 2 that studies of interference to and from EESS systems operating above 3 000 GHz should take into account the technical and operational parameters provided in Annex 1.

  10. Agenda Item 1.11

  11. Agenda Item 1.11

  12. Agenda Item 1.11 - (1) NOTE : RG WP7B CG WP 4A, WP 5C

  14. Agenda Item 1.11 - (3) Resolution 753 (Rev.WRC‑07) : Use of the band 22.55-23.15 GHz by the space research service resolves • to invite ITU-R to conduct sharing studies between space research service systems operating in the Earth-to-space direction and the fixed, inter-satellite and mobile services in the band 22.55-23.15 GHz, to recommend appropriate sharing criteria for an allocation to the space research service in the Earth-to-space direction; • to invite WRC‑11 to review the results of the studies under resolves 1 and consider the inclusion of the sharing criteria within the Radio Regulations and appropriate modifications to the Table of Frequency Allocations,

  15. Agenda Item 1.12

  19. Agenda Item 1.12 - (3) Resolution 754 (Rev.WRC‑07) : Consideration of modification of the aeronautical component of the mobile service allocation in the 37-38 GHz band for protection of other primary services in the band resolves • to invite ITU‑R to conduct appropriate studies involving the aeronautical mobile service and the affected primary services in the band 37-38 GHz in order to determine the compatibility of the aeronautical mobile service with these other services; • to invite WRC‑11 to review the results of the studies under resolves 1 and consider the inclusion of any appropriate compatibility criteria within the Radio Regulations or appropriate modifications to the Table of Frequency Allocations,
