Detail of Frequency Band

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 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 stations cannot use the band.

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.

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.

 Resolution 155 (WRC-15) shall apply.

The operation of earth stations in motion communicating with the FSS is subject to Resolution 156 (WRC-15).
