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.

All emissions are prohibited in the following bands:
1 400 – 1 427 MHz,
2 690 – 2 700 MHz, except those provided for by No. 5.422 of RR,
10.68 – 10.7 GHz, except those provided for by No. 5.483 of RR,
15.35 – 15.4 GHz, except those provided for by No. 5.511 of RR,
23.6 – 24 GHz,
31.3 – 31.5 GHz,
31.5 – 31.8 GHz, in Region 2,
48.94 – 49.04 GHz, from airborne stations,
50.2 – 50.4 GHz,
52.6 – 54.25 GHz,
86—92 GHz,
100 – 102 GHz,
109.5 – 111.8 GHz,
114.25 – 116 GHz,
148.5 – 151.5 GHz,
164 – 167 GHz,
182 – 185 GHz,
190 – 191.8 GHz,
200 – 209 GHz,
226 – 231.5 GHz,
250 – 252 GHz.
The allocation to the Earth exploration-satellite service (passive) and the space research service (passive) in the band 50.2 – 50.4 GHz should not impose undue constraints on the use of the adjacent bands by the primary allocated services in those bands.

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.
