Abstract

A radio bus system formed by combining a spread spectrum (SS) communication radio bus system with an electrical power line bus system using a spread spectrum modulated signal of the same signal format as that used in the radio bus system. An information signal transmission system is formed which transmits an information signal between a controller and a device which may or may not be connected to the electrical power line bus system, the information signal to be transmitted being converted into a spread spectrum modulated signal by an SS modem on a transmitter side and being succeedingly converted into a radio signal in a radio transmitter part of the transceiver section on the transmitter side for radiating the radio signal. The received radio signal is then converted on the receiver side into a spread spectrum modulated signal in a radio receiver part of the transceiver section and converted into the information signal by the SS modem on the receiver side for transmission through the electrical power line.
