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 designing systems for the inter-satellite service in the band 32,3 – 33 GHz, for the radionavigation service in the band 32 – 33 GHz, and for the space research service (deep space) in the band 31.8 – 32.3 GHz, administrations shall take all necessary measures to prevent harmful interference between these services, bearing in mind the safety aspects of the radionavigation service (see Recommendation 707).

Administrations should take practical measures to minimize the potential interference between stations in the fixed service and airborne stations in the radionavigation service in the 31.8 – 33.4 GHz band, taking into account the operational needs of the airborne radar systems.
