Multichannel radio communication system for automated power line distribution networks

摘要: An automated electric power distribution network includes a radio communication system for transmitting multipurpose, multitone signals in one or more signaling channels over the auxiliary channel of commercial broadcast stations. Energy management terminals receive at remote locations served by network. Radio receivers have frequency selective detectors responsive to different signals. The allocation provides links effecting common energy usage related responses grouped separate locations. Complex address and/or function encoded signal information is reduced providing reception several available television station channel.
