MMW COALITION

So much more spectrum exists above 100 GHz. Currently RR 5.340 presently prohibits "all emissions" in several forbidden bands (shown in dark gray) to protect radio astronomy and passive satellite sensors which detect very low levels of energy and might be harmed by interference if special care was not taken to protect such passive systems. The ITU agreed in Resolution 731, at the request of the US and European countries, to study if and under what conditions sharing the ten forbidden bands may be shared. The issue of out of band emissions (OOBE) into the passive bands is also an important study area to assure that adjacent terrestrial transmissions do not leak into or interfere with satellite sensors and studies of limits on such emissions to protect nearby passive bands are beginning. The mmWave coalition is fostering a constructive and win-win approach to learning about these issues and developing technologies that will allow successful commercialization of the spectrum above 100 GHz..
