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 band is foreseen to be designated for NATO harmonised non-civil use.

Use of the bands 54.25 – 56.9 GHz, 57 – 58.2 GHz and 59 – 59.3 GHz by the inter-satellite service is limited to satellites in the geostationary-satellite orbit. The single-entry power flux-density at all altitudes from 0 km to 1 000 km above the Earth's surface produced by a station in the inter-satellite service, for all conditions and for all methods of modulation, shall not exceed –147 dB (W/(m2 100 MHz)) for all angles of arrival.

In the bands 55.78 – 58.2 GHz, 59 – 64 GHz, 66 – 71 GHz, 122.25 – 123 GHz, 130 – 134 GHz, 167 –174.8 GHz and 191.8 – 200 GHz, stations in the aeronautical mobile service may be operated subject to not causing harmful interference to the inter-satellite service (see No. 5.43 of RR).

In the band 59 – 64 GHz, airborne radars in the radiolocation service may be operated subject to not causing harmful interference to the inter-satellite service (see No. 5.43 of RR).
