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.

The use of the bands 1 525 – 1 559 MHz and 1 626.5 – 1 660.5 MHz by the mobile-satellite services is subject to coordination under No. 9.11A of RR.

The use of the band 1 645.5 – 1 646.5 MHz by the mobile-satellite service (Earth-to-space) and for inter – satellite links is limited to distress and safety communications (see Article 31 of RR).

For the use of the bands 1 518 – 1 544 MHz, 1 545 – 1 559 MHz, 1 610 – 1 645.5 MHz, 1 646.5 –1 660.5 MHz, 1 668 – 1 675 MHz, 1 980 – 2 010 MHz, 2 170 – 2 200 MHz, 2 483.5 – 2 520 MHz and 2 670 – 2 690 MHz by the mobile-satellite service, see Resolutions 212 and 225.
