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.

The use of the bands 137 – 138 MHz, 148 – 150.05 MHz, 399.9 – 400.05 MHz, 400.15 – 401 MHz, 454 – 456 MHz and 459 – 460 MHz by the mobile-satellite service is limited to non-geostationary-satellite systems.

The band 449.75 – 450.25 MHz may be used for the space operation service (Earth-to-space) and the space research service (Earth-to-space), subject to agreement obtained under No. 9.21 of RR.

The use of the bands 454 – 456 MHz and 459 – 460 MHz by the mobile-satellite service is subject to coordination under No. 9.11A of RR.

The frequency band 450-470 MHz is identified for use by administrations wishing to implement International Mobile Telecommunications (IMT). See Resolution 224 (Rev.WRC-19). 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.
