Background

FCC rules provide that certain unlicensed radio transmitters (TV White Space Devices) can operate on broadcast television spectrum when that spectrum is not used by a licensed service (TV white spaces).  Since LPADs including wireless microphones also operate on broadcast television spectrum, they can receive interference from these unlicensed TV white space devices. The FCC has set aside channels that can be used by LPADs including wireless microphones and established a process for registration of these devices to prevent interference from TV white space devices.
