Abstract: The present invention relates to a system for networking electrical devices to provide interactive communication therebetween utilizing the existing power distribution network installed in a building or structure. Each device utilizes employs an RF transmitter/receiver, a power line coupler and circuitry to regulate the 120v, 60 Hz power being distributed through the network. The RF transmitter/receiver at each device convert the information signal generated in the device, to a signal which is supplied to the power coupler. The power coupler introduces the RF signal to the power distribution network. A display device containing a like power coupler and RF transmitter/receiver receives the signal from the distribution network. The display device converts the signal back to a signal format used to display the information. The physical location of the display device can be anywhere within the building since the signal has been transmitted over the installed power distribution network.
