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 bands 1 525 – 1 544 MHz, 1 545 – 1 559 MHz, 1 626.5 – 1 645.5 MHz and 1 646.5 – 1 660.5 MHz shall not be used for feeder links of any service. In exceptional circumstances, however, an earth station at a specified fixed point in any of the mobile-satellite services may be authorized by an administration to communicate via space stations using these bands.

In applying the procedures of Section II of Article 9 of RR to the mobile-satellite service in the bands 1 530 – 1 544 MHz and 1 626.5 – 1 645.5 MHz, priority shall be given to accommodating the spectrum requirements for distress, urgency and safety communications of the Global Maritime Distress and Safety System (GMDSS). Maritime mobile-satellite distress, urgency and safety communications shall have priority access and immediate availability over all other mobile satellite communications operating within a network. Mobile-satellite systems shall not cause unacceptable interference to, or claim protection from, distress, urgency and safety communications of the GMDSS. Account shall be taken of the priority of safety-related communications in the other mobile-satellite services. The provisions of Resolution 222 shall apply.

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.

Mobile earth stations in the mobile-satellite service operating in the bands 1 631.5 – 1 634.5 MHz and 1 656.5 – 1 660 MHz shall not cause harmful interference to stations in the fixed service operating in the countries listed in No. 5.359 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.
