Detail of Frequency Band
Non-civil Utilisation – Priority
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 Utilisation – Subsidiarity
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 Utilisation – Not Used
Non-civil stations cannot use the band.

The following frequency bands in the range 275-1 000 GHz are identified for use by administrations for passive service applications:
- radio astronomy service: 275 – 323 GHz, 327 – 371 GHz, 388 – 424 GHz, 426 – 442 GHz, 453 –510 GHz, 623 – 711 GHz, 795 – 909 GHz and 926 – 945 GHz;
- Earth exploration-satellite service (passive) and space research service (passive): 275-286 GHz, 296-306 GHz, 313-356 GHz, 361-365 GHz, 369-392 GHz, 397-399 GHz, 409-411 GHz, 416-434 GHz, 439-467 GHz, 477-502 GHz, 523-527 GHz, 538-581 GHz, 611-630 GHz, 634-654 GHz, 657-692 GHz, 713-718 GHz, 729-733 GHz, 750-754 GHz, 771-776 GHz, 823-846 GHz, 850-854 GHz, 857-862 GHz, 866-882 GHz, 905-928 GHz, 951-956 GHz, 968-973 GHz and 985-990 GHz.
The use of the range 275-1 000 GHz by the passive services does not preclude use of this range by active services. Administrations wishing to make frequencies in the 275-1 000 GHz range available for active service applications are urged to take all practicable steps to protect these passive services from harmful interference until the date when the Table of Frequency Allocations is established in the above-mentioned 275-1 000 GHz frequency range.
All frequencies in the range 1 000-3 000 GHz may be used by both active and passive services.
