Abstract
Communications signals are transmitted over a power distribution network. A plurality of communications stations which are coupled to the power lines are served by a base station. Communications signals are coupled between the base station and the distribution network, and the flow of the communications signals is controlled according to the station that it is desired to communicate with by preferentially transmitting along or receiving from a power line to which the desired communications station is coupled. The base station can be coupled to each of the power lines or to the busbars at a distribution station.
