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 11.7 – 12.5 GHz in Regions 1 and 3, the fixed, fixed-satellite, mobile, except aeronautical mobile, and broadcasting services, in accordance with their respective allocations, shall not cause harmful interference to, or claim protection from, broadcasting-satellite stations operating in accordance with the Regions 1 and 3 Plan in Appendix 30 of RR.

Additional allocation: in Region 1, the band 11.7 – 12.5 GHz, in Region 2, the band 12.2 – 12.7 GHz and, in Region 3, the band 11.7 – 12.2 GHz, are also allocated to the fixed-satellite service (space-to-Earth) on a primary basis, limited to non-geostationary systems and 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 broadcasting-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 in this case. 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.

Assignments to stations of the broadcasting-satellite service which are in conformity with the appropriate regional Plan or included in the Regions 1 and 3 List in RR Appendix 30 may also be used for transmissions in the fixed-satellite service (space-to-Earth), provided that such transmissions do not cause more interference, or require more protection from interference, than the broadcasting-satellite service transmissions operating in conformity with the Plan or the List, as appropriate.
