ABSTRACT:
One end of a balanced line is connected to a base station. A transmitting and receiving antenna is connected to the other end of the balanced line. The balanced line not only transmits a signal sent from the base station to the transmitting and receiving antenna and at the same time leaks a part of the transmitted signal as the radio waves, but also transmits the received signal at the transmitting and receiving antenna to the base station. In a room where the balanced line is laid, wireless communication terminals are provided. The wireless communication terminals transmit and receive radio waves to or from either the balanced line or the transmitting and receiving antenna.
