Non-civil Utilisation – Priority

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 Utilisation – Subsidiarity

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 Utilisation – Not Used

Non-civil stations cannot use the band.

Civil Utilisation – Priority

Band reserved for civil utilisation. If non-civil utilisation is also stated with priority, the band is being used equally with non-civil utilisation on the basis of coordination.

Civil Utilisation – Subsidiarity

Civil stations can use the band with subsidiarity to non-civil ones (which use the band with priority), but must not interfere and do not have rihgt to protection against interference by non-civil utilisation.

Civil Utilisation – Not Used

Civil stations cannot use the band.

Note 5.547

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.

Note 5.550C

The use of the frequency bands 37.5-39.5 GHz (space-to-Earth), 39.5-42.5 GHz (space-to-Earth), 47.2- 50.2 GHz (Earth-to-space) and 50.4-51.4 GHz (Earth-to-space) by a non-geostationary-satellite system in the fixed-satellite service is subject to the application of the provisions of No. 9.12 for coordination with other non-geostationary satellite systems in the fixed-satellite service but not with non-geostationary-satellite systems in other services. Resolution 770 (WRC-19) shall also apply, and No. 22.2 shall continue to apply. (WRC-19)

Note 5.550B

The frequency band 37-43.5 GHz, or portions thereof, is identified for use by administrations wishing to implement the terrestrial component of International Mobile Telecommunications (IMT). This identification does not preclude the use of this frequency band by any application of the services to which it is allocated and does not establish priority in the Radio Regulations. Because of the potential deployment of FSS earth stations within the frequency range 37.5-42.5 GHz and high-density applications in the fixed-satellite service in the frequency bands 39.5-40 GHz in Region 1, 40-40.5 GHz in all Regions and 40.5-42 GHz in Region 2 (see No. 5.516B), administrations should further take into account potential constraints to IMT in these frequency bands, as appropriate. Resolution 243 (WRC-19) applies. (WRC-19)
