A system for communicating signals and data without the need for continuous telephone lines is described. This system provides a base unit connected to incoming signals, such as cable, satellite, PCS, cellular, fiber optics, XDSL, ISDN, etc, one or more extension units connected to the users telephone or electronics equipment and a communication link between the base unit and the one or more extension units. The preferred communication link employs a combination of an A/C power line carrier and a wireless RF channel. This system provides for the communication signals from a variety of sources throughout a building or office without requiring either dedicated telephone lines or the availability of AC power outlets near the user's telephone extension equipment. This invention, in its preferred embodiments, is specifically adapted to meet the technical requirements of A/C power line communications, while taking advantage of RF communication within buildings or facilities.
