Abstract

PURPOSE:To realize an effective use of the frequency band as well as to enable a large capacity exchange connection for the mobile radio communication, by carrying out the multiplication through the time division. CONSTITUTION:Transmitter 5, receiver 6 and control circuit 14 to decide the using frequency and the time slot are installed at the terminal unit side; and transmitter 9, receiver 10, control circuit 15 to decide the using frequency and the time slot and exchange unit 11 for the radio circuit and the wire circuit are provided at the master station side. In case the call or the information is transferred, the information is sent via time slot t1 within the f1 frequency band. And the information is sent out from the unit of the master station via frequency band f2 and time slot t2. Thus, the multiplication is carried out through the time-division method.
