Non-civil Utilisation – Priority
Band reserved for non-civil utilisation. If civil utilisation is also stated with priority, the band is being used equally with civil utilisation on the basis of coordination.
Non-civil Utilisation – Subsidiarity
Non-civil stations can use the band with subsidiarity to civil ones (which use the band with priority), but must not interfere and do not have rihgt to protection against interference by civil utilisation.
Non-civil Utilisation – Not Used
Non-civil stations cannot use the band.

Civil stations cannot use the band.
Note 5.538
Additional allocation: the bands 27.500 – 27.501 GHz and 29.999 – 30.000 GHz are also allocated to the fixed-satellite service (space-to-Earth) on a primary basis for the beacon transmissions intended for up-link power control. Such space-to-Earth transmissions shall not exceed an equivalent isotropically radiated power (e.i.r.p.) of +10 dBW in the direction of adjacent satellites on the geostationary-satellite orbit.
Note 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.
Note 5.484A
The use of the bands 10.95 – 11.2 GHz (space-to-Earth), 11.45 – 11.7 GHz (space-to-Earth), 11.7 – 12.2 GHz (space-to-Earth) in Region 2, 12.2 – 12.75 GHz (space-to-Earth) in Region 3, 12.5 – 12.75 GHz (space-to-Earth) in Region 1, 13.75 – 14.5 GHz (Earth-to-space), 17.8 – 18.6 GHz (space-to-Earth), 19.7 – 20.2 GHz (space-to-Earth), 27.5 – 28.6 GHz (Earth-to-space), 29.5 – 30 GHz (Earth-to-space) by a non-geostationary-satellite system in the fixed-satellite service is subject to application of the provisions of No. 9.12 of RR for coordination with other non-geostationary-satellite systems in the fixed-satellite service. Non-geostationary-satellite systems in the fixed-satellite service shall not claim protection from geostationary-satellite networks in the fixed-satellite service operating in accordance with RR, irrespective of the dates of receipt by the Radiocommunication Bureau of ITU of the complete coordination or notification information, as appropriate, for the non-geostationary-satellite systems in the fixed-satellite service and of the complete coordination or notification information, as appropriate, for the geostationary-satellite networks, and No. 5.43A of RR does not apply. Non-geostationary-satellite systems in the fixed-satellite service in the above bands shall be operated in such a way that any unacceptable interference that may occur during their operation shall be rapidly eliminated.
Note 5.516B
The following bands are identified for use by high-density applications (HDFSS) 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 in RR does not establish priority among users of the bands. Administrations should take this into account when considering regulatory provisions in relation to these bands. See Resolution 143.
Note 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.
