Patent GB-2050124-A (GB)
Title: Carrier current communications system
IPC: H04B3/54
Filed: 1978-11-29
Abstract: A plurality of transmitters and receivers arranged for carrier current communications are generally placed throughout a large building and are coupled to selected portions of the power distribution system at stairwell exit and lighting risers. Coupling circuits are applied to both remote transceivers and the central station transceivers to insure that remote station receivers always present high impedance to the power line at the carrier frequencies and that remote transmitters do not load the lines. At the central station, a bridge arrangement of the networks couples energy to and from the lines, with additional isolation between receiver and transmitter circuits. Mutual interference of transmitted and received signals is avoided by taking advantage of the impedance in the length of line from the central station to coupling and line conditioning circuits, and capacitor tuning to the center frequency of the transmitter line and to the center frequency of the receiver circuits.
