Network combining wired and non-wired segments
View Patent ↗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 ( 5 a, 5 b, 5 c, 5 d, 5 e ) in the building, wherein access to the wires is provided by means of outlets ( 61 a, 61 d ), 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 ( 24 b ) connected by wires and data units ( 24 a, 24 d ) connected without wires.
