Wireless Microphone Operation for Mega-Events in the 1425-1525 MHz Band

Due to the repurpossing of the 600 MHz band that is scheduled to be completed in July 2020, the alternate 1435 – 1525 MHz band will be more heavily used by broadcasters for wireless microphones to cover mega-events such as the Superbowl, World Series, Kentucky Derby, national elections, the Academy Awards, etc. This band has been used for wireless microphones through the use of special temporay authorization (STA) granted by the FCC. This procedure will effectively by normalized through an approval process with the Aerospace and Flight Test Radio Coordinating Council (?AFTRCC?), the agency that coordinates aeronautical mobile telemetry (i.e. flight training), the primary service in this band. Wireless microphone equipment must incorporate location, date, and time awareness. AFTRCC will provide a digital code (i.e. an electronic key) that will unlock the equipment, enabling it to work at the approved time and location. This paper and presentation will detail the regulations, eligilibity, and procedure for operating wireless microphones in this frequency band.
