In October we published a post here entitled
This dealt with proposals from European and Asian ITU members to put on the WRC-19 agenda new allocations up to 450 GHz and 1000 GHz, respectively. As far as we can tell the US WRC-15 was totally blindsided by this issue and had no position on it going into this year's conference. We believe that this is partly due to a fundamental flaw in US WRC preparation at both FCC and DOS that is nominally transparent but in actuality is stacked in favor of deep pocket major entities with little or no outreach to other US interests.
The main US deep pocket entities are focused, like most of US industry, on near term gains. They are not apposed to moving the upper limits of spectrum allocations above the present 275 GHz and probably do not even oppose new FCC service rules above 95 GHz, but don't want it to detract from their near term gratification at lower frequencies. Thus given limited resources at FCC and DOS such long term issues get little or no attention.
So as a public service we are linking here to the agenda item for WRC-19 that deals with new allocations in the 275-450 GHz range in the hope that it stimulates interest when WRC-19 preparation begins.
