A wireless microphone system, also termed "radio microphone" or "rf microphone" is essentially a miniaturized version of an FM radio broadcasting system. In a commercial radio system, a disc-jockey speaks into a microphone that is connected to a high-power transmitter. The transmitted radio waves are picked up by an FM receiver and converted into the audio signal, heard through a loudspeaker. Handheld wireless systems are commonly found in rock-and-roll applications, where singers like to wander around the stage making lewd motions with their free hand whist lying on their back.
They are also used extensively in television production, where talk-show hosts can roam the audience with impunity. The transmitter electronics and battery by which the transmitter and microphone receive their power are built into the casing of the microphone. There are many standards and frequencies in wireless microphones. They can transmit, for example, in radiowaves UHF, VHF, FM, AM, and some cheap models, in infrared light. The infrared microphones have the disadvantage that they require a line of sight between the microphone and the receiver, while more expensive radio frequency models don't.
