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 use of the band 400.15 – 401 MHz by the mobile-satellite service is subject to coordination under No. 9.11A of RR. The power flux-density limit indicated in Annex 1 of Appendix 5 of RR shall apply until such time as a competent world radiocommunication conference revises it.

In making assignments to space stations in the mobile-satellite service in the frequency bands 137- 138 MHz, 387-390 MHz and 400.15-401 MHz and in the maritime mobile-satellite service (space-to-Earth) in the frequency bands 157.1875-157.3375 MHz and 161.7875-161.9375 MHz, administrations shall take all practicable steps to protect the radio astronomy service in the frequency bands 150.05-153 MHz, 322-328.6 MHz, 406.1-410 MHz and 608-614 MHz from harmful interference from unwanted emissions as shown in the most recent version of Recommendation ITU-R RA.769. (WRC-19)

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 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 400.15 – 401 MHz is also allocated to the space research service in the space-to-space direction for communications with manned space vehicles. In this application, the space research service will not be regarded as a safety service.
