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 bands 31.8 – 33.4 GHz, 37 – 40 GHz, 40.5 – 43.5 GHz, 51.4 – 52.6 GHz, 55.78 – 59 GHz and 64 –66 GHz are available for high-density applications in the fixed service (see Resolution 75). Administrations should take this into account when considering regulatory provisions in relation to these bands. Because of the potential deployment of high-density applications in the fixed-satellite service in the bands 39.5 – 40 GHz and 40.5 – 42 GHz (see No. 5.516B of RR), administrations should further take into account potential constraints to high-density applications in the fixed service, as appropriate.

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).

Use of the band 56.9 – 57 GHz by inter-satellite systems is limited to links between satellites in geostationary-satellite orbit and to transmissions from non-geostationary satellites in high-Earth orbit to those in low-Earth orbit. For links between 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, for all conditions and for all methods of modulation, shall not exceed –147 dB(W/m2 100 MHz) for all angles of arrival.
