A communication system is disclosed for providing broadband multimedia services using one or more high-voltage cables of a power distribution network, while the power distribution network is supplying electrical power. A radio-frequency signal at a first location is coupled to the high-voltage cable, transported over the high-voltage cable, and then coupled from the high-voltage cable at a second location. The radio-frequency signal at the first location is modulated with information and demodulated at the second location, thereby providing broadband multimedia service between the two locations. The broadband multimedia communications system may be used for a variety of communication needs, such as telephone service, video service, internet service, and other services requiring high-speed data transfers.
