MVDS at 12 GHz [microwave video distribution services]

In August 1989 the UK Government announced a tranche a spectrum of 40 GHz to be used for a microwave video distribution service (MVDS). Although it was stated that the UK Government saw 40 GHz as the long term permanent home for MVDS it also stated that the Government had decided to leave open for perhaps the next year a decision on whether spectrum at 12 GHz should be made available to MVDS in addition to the tranche at 40 GHz. In the light of this decision the UK Government commissioned further studies on MVDS at 12 GHz. The author reports on these studies, addressing a number of sharing issues that arise in the 12 GHz band
