Wireless mics have become essential audio tools in movies, television, and live situations, since the actors or announcers can move freely anywhere on the stage or set without having to deal with a mic , the broadcast spectrum allocated to wireless microphones has been shrinking year after year as the Federal Communications Commission, the FCC, has re-allocates portions to be used for other wireless FCC has suggested that perhaps wireless mics could more efficiently use their portion of the spectrum by multiplexing several mics on the same frequency, as cell phones and other digital devices issue with this is that this multiplexing would create latency, which may not be a problem for cell phones or other devices, but would render wireless mics unusable for many of the uses they currently fill now. For instance, the latency would cause on-camera announcers to be out of sync with the picture, or live presenters in a theatrical situation to have “ball-park or stadium-like” delay on their of wireless mics need to be vocal advocates to preserve their portion of the spectrum, so that wireless mics can continue to be used in the future.
