The FCC has approved new rules allowing for the use of Wireless Multi-Channel Audio Systems (WMAS) technology, which increases the efficiency of wireless microphones. This technology enables more microphones to operate without requiring additional spectrum allocation. WMAS can now operate on both licensed and unlicensed bases while maintaining the spectrum rights of other users.
The rules permit WMAS operation in broadcast TV bands, the 600 MHz duplex gap, and other designated frequency bands. These changes aim to meet the growing demand for wireless microphones across various settings. The decision was made by the FCC on February 15, 2024.
