Promoting Spectrum Access for Wireless Microphone Operations

In this document, the Commission addresses several petitions for reconsideration regarding recent decisions regarding wireless microphones. Specifically, the Commission makes technical revisions to the spurious emission limits that it had adopted for licensed wireless microphone operations in several frequency bands, and for unlicensed wireless microphone operations in the TV bands and in the 600 MHz guard band and duplex gap. The Commission also clarifies output power measurements and how certain antenna-related part 15 rules apply with respect to unlicensed wireless microphones, and revises and clarifies requirements for existing and legacy unlicensed wireless microphones during and after the post-incentive auction transition period. This action promotes the Commission's goal of accommodating wireless microphone users' needs through access to spectrum resources following the incentive auction and reconfiguration of the TV bands.
