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.

Additional allocation: the bands 18 – 18.3 GHz in Region 2 and 18.1 – 18.4 GHz in Regions 1 and 3 are also allocated to the meteorological-satellite service (space-to-Earth) on a primary basis. Their use is limited to geostationary satellites.

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 use of the band 18.1 – 18.4 GHz by the fixed-satellite service (Earth-to-space) is limited to feeder links of geostationary-satellite systems in the broadcasting-satellite service.
