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

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 5.525
In order to facilitate interregional coordination between networks in the mobile-satellite and fixed-satellite services, carriers in the mobile-satellite service that are most susceptible to interference shall, to the extent practicable, be located in the higher parts of the bands 19.7 – 20.2 GHz and 29.5 – 30 GHz.
Note 5.526
In the bands 19.7 – 20.2 GHz and 29.5 – 30 GHz in Region 2, and in the bands 20.1 – 20.2 GHz and 29.9 – 30 GHz in Regions 1 and 3, networks which are both in the fixed-satellite service and in the mobile-satellite service may include links between earth stations at specified or unspecified points or while in motion, through one or more satellites for point-to-point and point-to-multipoint communications.
Note 5.527
In the bands 19.7 – 20.2 GHz and 29.5 – 30 GHz, the provisions of No. 4.10 of RR do not apply with respect to the mobile-satellite service.
Note 5.528
The allocation to the mobile-satellite service is intended for use by networks which use narrow spot-beam antennas and other advanced technology at the space stations. Administrations operating systems in the mobile-satellite service in the band 19.7 – 20.1 GHz in Region 2 and in the band 20.1 – 20.2 GHz shall take all practicable steps to ensure the continued availability of these bands for administrations operating fixed and mobile systems in accordance with the provisions of No. 5.524 of RR.
Note 5.484A
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.
Note 5.516B
The following bands are identified for use by high-density applications (HDFSS) in the fixed-satellite service:
17.3 – 17.7 GHz (space-to-Earth) in Region 1,
18.3 – 19.3 GHz (space-to-Earth) in Region 2,
19.7 – 20.2 GHz (space-to-Earth) in all Regions,
39.5 – 40 GHz (space-to-Earth) in Region 1,
40 – 40.5 GHz (space-to-Earth) in all Regions,
40.5 – 42 GHz (space-to-Earth) in Region 2,
47.5 – 47.9 GHz (space-to-Earth) in Region 1,
48.2 – 48.54 GHz (space-to-Earth) in Region 1,
49.44 – 50.2 GHz (space-to-Earth) in Region 1,
And
27.5 – 27.82 GHz (Earth-to-space) in Region 1,
28.35 – 28.45 GHz (Earth-to-space) in Region 2,
28.45 – 28.94 GHz (Earth-to-space) in all Regions,
28.94 – 29.1 GHz (Earth-to-space) in Region 2 and 3,
29.25 – 29.46 GHz (Earth-to-space) in Region 2,
29.46 – 30 GHz (Earth-to-space) in all Regions,
48.2 – 50.2 GHz (Earth-to-space) in Region 2.
This identification does not preclude the use of these bands by other fixed-satellite service applications or by other services to which these bands are allocated on a co-primary basis and in RR does not establish priority among users of the bands. Administrations should take this into account when considering regulatory provisions in relation to these bands. See Resolution 143.
Note 5.484B
Resolution 155 (WRC-15) shall apply.
Note 5.527A
The operation of earth stations in motion communicating with the FSS is subject to Resolution 156 (WRC-15).
