Wireless Microphone Beacon

摘要

Disclosed is a method and system for a radio beacon to protect wireless microphones from interference. One embodiment involves providing each wireless microphone system with a signal detector that detects interfering signals and a 'beacon' transmitter that sends a multitone beacon signal. Users that transmit on a potentially interfering frequency employ a beacon detector that 'listens' for the beacon signal. The users inhibit transmission if such a signal is detected.
