Claim:
A wireless communication system comprising: a main wireless communication apparatus; and a sub-wireless communication apparatus adjacent to said main wireless communication apparatus and connected with said main wireless communication apparatus via a dedicated line, each of said main wireless communication apparatus and said sub-wireless communication apparatus including: a receiver for reproducing audio signals from radio signals received by an antenna; a transmitter for converting audio signals to radio signals and transmitting the radio signals from the antenna as a transmission; a controller for controlling operation of said receiver and said transmitter, and for controlling a power supply to said receiver and said transmitter; an output portion for outputting signals from said controller; and an input portion for inputting signals into said controller; wherein said main wireless communication apparatus and said sub-wireless communication apparatus are configured and interconnected such that: upon a start of power supply to said transmitter of said main wireless communication apparatus, said controller of said main wireless communication apparatus continuously transmits reception limit signals to said controller of said sub-wireless communication apparatus via said dedicated line until the power supply to said transmitter of said main wireless communication apparatus is stopped; upon receiving the reception limit signals from said controller of said main wireless communication apparatus and until the reception limit signals are no longer received from said controller of said main wireless communication apparatus, said controller of said sub-wireless communication apparatus stops a power supply to said receiver of said sub-wireless communication apparatus; upon elapse of a predetermined period of time after the start of power supply to said transmitter of said main wireless communication apparatus, said controller of said main wireless communication apparatus allows said transmitter of said main wireless communication apparatus to start the transmission of the radio signals while the power supply to said receiver of said sub-wireless communication apparatus remains stopped by said controller of said sub-wireless communication apparatus due to receipt of the reception limit signals from said controller of said main wireless communication apparatus; and when the reception limit signals from said controller of said main wireless communication apparatus are no longer received by said controller of said sub-wireless communication apparatus, said controller of said sub-wireless communication apparatus provides a power supply to said receiver of said sub-wireless communication apparatus.
