[2] JFMG was contracted by the communications regulator Ofcom to provide spectrum management and licensing services for Programme Making and Special Events (PMSE).
Coordinated licenses grant the holder exclusive use of specific frequencies or spectrum blocks at a particular location for a defined period.
[12] Licenses are required to use wireless microphones on vacant TV channels in the United States, as they are part of the Broadcast Auxiliary Service (BAS).
[16] This change is unrelated to, but often confused with, the White Space device debate currently taking place in the U.S.
The same Report and Order, issued on January 15, 2010, also permits most wireless microphones and other 'low power auxiliary stations' in the "core TV band" (TV channels 2 through 51, except 37) to operate with a transmit power of up to 50 mW without a license, under a special waiver of Part 15 rules.
Licenses for this band are only available to licensees of radio and TV stations, and broadcasters are likely to report unauthorized use due to the high potential for interference.
Starting in 2017, the amount of TV band spectrum available for wireless microphone use decreased as a result of the incentive auction, which was completed on April 13, 2017.
However, the responsibility falls on the user of the wireless microphone to resolve any interference caused to licensed radio communications services.
