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.

In the bands 1 400 – 1 727 MHz, 101 – 120 GHz and 197 – 220 GHz, passive research is being conducted by some countries in a programme for the search for intentional emissions of extraterrestrial origin.

In the frequency bands:
137-138 MHz,
157.1875-157.3375 MHz,
161.7875-161.9375 MHz,
387-390 MHz,
400.15-401 MHz,
1 452-1 492 MHz,
1 525-1 610 MHz,
1 613.8-1 626.5 MHz,
2 655-2 690 MHz,
21.4-22 GHz,
Resolution 739 (Rev.WRC-19) applies. (WRC-19).

The use of the bands 1 164 – 1 300 MHz, 1 559 – 1 610 MHz and 5 010 – 5 030 MHz by systems and networks in the radionavigation-satellite service for which complete coordination or notification information, as appropriate, is received by the Radiocommunication Bureau of ITU after 1 January 2005 is subject to the application of the provisions of Nos. 9.12, 9.12A and 9.13 of RR. Resolution 610 shall also apply; however, in the case of radionavigation-satellite service (space-to-space) networks and systems, Resolution 610 shall only apply to transmitting space stations. In accordance with No. 5.329A of RR, for systems and networks in the radionavigation-satellite service (space-to-space) in the bands 1 215 – 1 300 MHz and 1 559 – 1 610 MHz, the provisions of Nos. 9.7, 9.12, 9.12A and 9.13 of RR shall only apply with respect to other systems and networks in the radionavigation-satellite service (space-to-space).

Use of systems in the radionavigation-satellite service (space-to-space) operating in the bands 1 215 –1 300 MHz and 1 559 – 1 610 MHz is not intended to provide safety service applications, and shall not impose any additional constraints on radionavigation-satellite service (space-to-Earth) systems or on other services operating in accordance with the Table of Frequency Allocations.
