The remote wireless speakerphone system comprises a base receiver for direct connection to telephone company lines to receive and transmit voice information over the lines. The base receiver has a speaker which has sufficient power to make voice information received on the telephone line audible in a room. The system also includes a transmitter unit sized to be carried on the person of the user. The transmitter unit includes a microphone positioned to take up the speaking voice of the user and a radiotransmitter which transmits this signal to the receiver. The receiver delivers this voice information to the telephone company line. In this way, the user is free of wires connecting him to the base unit and can conduct two-way conversation by listening to the speaker on the base unit and speaking into the microphone he carries.
