WRC-23 Agenda Item 1.14 Possible Adjustments to EESS (passive) Allocations
Current Use
231.5–252 GHz Review of EESS (passive) Allocations
"to review and consider possible adjustments of the existing or possible new primary frequency allocations to EESS (passive) in the frequency range 231.5-252 GHz, to ensure alignment with more up-to-date remote-sensing observation requirements, in accordance with Resolution 662 (WRC-19);"
WRC-27 study for radiolocation use
Proposed Use
231.5–275 GHz WRC-27 study for primary radiolocation allocation
WRC-27 agenda item 1.8:
to consider possible additional spectrum allocations to the radiolocation service on a primary basis in the frequency range 231.5-275 GHz and possible new identifications for radiolocation service applications in the frequency bands within the frequency range 275-700 GHz for millimetric and sub-millimetric wave imaging systems, in accordance with Resolution 663 (Rev.WRC-23)
