Abstract
A wireless extension telephone system including a base unit connected to a telephone line and a remote extension unit. Both base and remote units each include a radio receiver and a radio transmitter. Also included in the remote unit is a modulator connected to said remote unit radio transmitter and circuitry limiting the amplitude of the modulated signals produced by said transmitter. A dialing circuit connected to said modulator causes the amplitude of each outgoing dial pulse to be transmitted at a level substantially higher than when no dial pulses are present.
