Abstract

PURPOSE:To attain radio communication between isolated locations with a low cost and a weak radio wave by connecting a repeater to an optional position of an electric wire installed between plural locations and sending/receiving a signal by a radio transmitter-receiver. CONSTITUTION:A sender side repeater 5 receives a radio wave having communication information sent from a radio transmitter 1, converts the wave into an AC electric signal having an information signal and sends the result to an electric wire 3. A receiver side repeater 7 extracts only communication information among high frequency component of a reception signal propagated through the electric wire 3, converts it into a radio wave having communication information and sends the result into air. Sender A or B of a floor F1 or F2 connects a sender repeater 5 to one of AC receptacles 4, operates the radio transmitter-receiver 1 to send the radio wave having communication information. On the other hand, a receiver C on a floor F3 connects a receiver side repeater 7 to one of the AC receptacle 6. Thus, the signal is received by a radio receiver 2 possessed by the receiver C.
