Abstract
A local area network (60) within a residence or other building, including both wired (5) and non-wired segments (53). The wired segments are based on new or existing wires (5a, 5b, 5c, 5d, 5e) in the building, wherein access to the wires is provided by means of outlets (61a, 61d), such as a telephone system, electrical power distribution system, or cable television wiring system. The non-wired segments are based on communication using propagated waves such as radio, sound, or light (e.g. infrared). The wired and non-wired segments interface in the outlet, using a module (50) that serves as mediator between the segments. The module can be integrated into the outlet, partially housed in the outlet, or attached externally to the outlet. Such a network allows for integrated communication of data units (24b) connected by wires and data units (24a, 24d) connected without wires.
