Footnotes


5.516B The following bands are identified for use by high-density applications in the fixed-satellite service:

17.3-17.7 GHz(space-to-Earth) in Region 1,
18.3-19.3 GHz(space-to-Earth) in Region 2,
19.7-20.2 GHz(space-to-Earth) in all Regions,
39.5-40 GHz(space-to-Earth) in Region 1,
40-40.5 GHz(space-to-Earth) in all Regions,
40.5-42 GHz(space-to-Earth) in Region 2,
47.5-47.9 GHz(space-to-Earth) in Region 1,
48.2-48.54 GHz(space-to-Earth) in Region 1,
49.44-50.2 GHz(space-to-Earth) in Region 1,
and
27.5-27.82 GHz(Earth-to-space) in Region 1,
28.35-28.45 GHz(Earth-to-space) in Region 2,
28.45-28.94 GHz(Earth-to-space) in all Regions,
28.94-29.1 GHz(Earth-to-space) in Region 2 and 3,
29.25-29.46 GHz(Earth-to-space) in Region 2,
29.46-30 GHz(Earth-to-space) in all Regions,
48.2-50.2 GHz(Earth-to-space) in Region 2.

This identification does not preclude the use of these bands by other fixed-satellite service applications or by other services to which these bands are allocated on a co-primary basis and does not establish priority in these Regulations among users of the bands. Administrations should take this into account when considering regulatory provisions in relation to these bands. See Resolution 143 (WRC-03).

5.523C No. 22.2 shall continue to apply in the bands 19.3-19.6 GHz and 29.1-29.4 GHz, between feeder links of non-geostationary mobile-satellite service networks and those fixed-satellite service networks for which complete Appendix 4 coordination information, or notification information, is considered as having been received by the Bureau prior to 18 November 1995.

5.523E No. 22.2 shall continue to apply in the bands 19.6-19.7 GHz and 29.4-29.5 GHz, between feeder links of non-geostationary mobile-satellite service networks and those fixed-satellite service networks for which complete Appendix 4 coordination information, or notification information, is considered as having been received by the Bureau by 21 November 1997.

5.535A The use of the band 29.1-29.5 GHz (Earth-to-space) by the fixed-satellite service is limited to geostationary-satellite systems and feeder links to non-geostationary-satellite systems in the mobile-satellite service. Such use is subject to the application of the provisions of No. 9.11A, but not subject to the provisions of No. 22.2, except as indicated in Nos. 5.523C and 5.523E where such use is not subject to the provisions of No. 9.11A and shall continue to be subject to Articles 9 (except No. 9.11A) and 11 procedures, and to the provisions of No. 22.2.

5.539 The band 27.5-30 GHz may be used by the fixed-satellite service (Earth-to-space) for the provision of feeder links for the broadcasting-satellite service.

5.540 Additional allocation: the band 27.501-29.999 GHz is also allocated to the fixed-satellite service (space-to-Earth) on a secondary basis for beacon transmissions intended for up-link power control.

5.541 In the band 28.5-30 GHz, the earth exploration-satellite service is limited to the transfer of data between stations and not to the primary collection of information by means of active or passive sensors.

5.541A Feeder links of non-geostationary networks in the mobile-satellite service and geostationary networks in the fixed-satellite service operating in the band 29.1-29.5 GHz (Earth-to-space) shall employ uplink adaptive power control or other methods of fade compensation, such that the earth station transmissions shall be conducted at the power level required to meet the desired link performance while reducing the level of mutual interference between both networks. These methods shall apply to networks for which Appendix 4 coordination information is considered as having been received by the Bureau after 17 May 1996 and until they are changed by a future competent world radiocommunication conference. Administrations submitting Appendix 4 information for coordination before this date are encouraged to utilize these techniques to the extent practicable.
