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 band 6 425 – 7 075 MHz, passive microwave sensor measurements are carried out over the oceans. In the band 7 075 – 7 250 MHz, passive microwave sensor measurements are carried out. Administrations should bear in mind the needs of the Earth exploration-satellite (passive) and space research (passive) services in their future planning of the bands 6 425 – 7 025 MHz and 7 075 – 7 250 MHz.

In making assignments in the band 6 700 – 7 075 MHz to space stations of the fixed-satellite service, administrations are urged to take all practicable steps to protect spectral line observations of the radio astronomy service in the band 6 650 – 6 675.2 MHz from harmful interference from unwanted emissions.

The space-to-Earth allocation to the fixed-satellite service in the band 6 700 – 7 075 MHz is limited to feeder links for non-geostationary satellite systems of the mobile-satellite service and is subject to coordination under No. 9.11A of RR. The use of the band 6 700 – 7 075 MHz (space-to-Earth) by feeder links for non-geostationary satellite systems in the mobile-satellite service is not subject to No. 22.2 of RR.

The use of the bands 4 500 – 4 800 MHz (space-to-Earth), 6 725 – 7 025 MHz (Earth-to-space) by the fixed-satellite service shall be in accordance with the provisions of RR Appendix 30B. The use of the bands 10.7 – 10.95 GHz (space-to-Earth), 11.2 – 11.45 GHz (space-to-Earth) and 12.75 – 13.25 GHz (Earth-to-space) by geostationary-satellite systems in the fixed-satellite service shall be in accordance with the provisions of RR Appendix 30B. The use of the bands 10.7 – 10.95 GHz (space-to Earth), 11.2 – 11.45 GHz (space-to-Earth) and 12.75 – 13.25 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.
