1. A wireless microphone system comprising:
- a signal detector configured to detect signals that interfere with a first microphone frequency of a wireless microphone;
a beacon generator, configured to generate a plurality of beacon signals, each at a different frequency; and
a transmitter configured to transmit the beacon signals upon the signal detector detecting signals that interfere with the first microphone frequency of the wireless microphone.

Abstract
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.
