ABSTRACT:
A communication system arrangement uses powerline distribution systems to broadcast a signal from the distribution station to individual households. The signal is coded, using a spread spectrum technique and the receiving arrangement is designed to process the signal quickly for transmission to downstream households. In a preferred embodiment equipment, within each household is able to initiate a communication to a predetermined computer for reporting in accordance with an instruction signal received over the powerline system. With this system, a narrow band broadcast signal arrangement is realized, which does not require extensive modification to the distribution system.
