した無線電話機。 In an MCA wireless telephone consisting of a base unit and multiple mobile units, the base unit has a means for modulating and transmitting the received and demodulated signal, and the mobile unit has a means for modulating and transmitting a signal that has been received and demodulated, and the mobile unit has a means for modulating and transmitting a signal that has been received and demodulated. It is equipped with a transmitter/receiver unit that transmits and receives a communication channel consisting of two predetermined reception frequencies, a switch that stops the reception output only when a transmission input occurs on the communication channel, and a transmission unit that outputs a transmission output modulated by the transmission input. A wireless telephone is characterized in that it communicates via a base unit using one transmitting frequency and one receiving frequency that are shared by the mobile units.
