System and Method for Carrying a Wireless Based Signal Over Wiring
First Claim
1. A device adapted to be connected to a network over LAN wiring in a building, the LAN wiring concurrently carrying a LAN signal in a LAN frequency band and a radio frequency signal in an intermediate frequency band different from and non-interfering with, the LAN frequency band, the device comprising:
- a first LAN connector connectable to the LAN wiring;
a high pass filter, coupled to the first LAN connector, passing only signals in the intermediate frequency band; and
an antenna;
a signal frequency converter coupled to the high pass filter, the signal frequency converter converting the radio frequency signal in the intermediate frequency band received from the LAN wiring to a radio frequency band signal for transmission through the antenna and converting a radio frequency band signal received from the antenna to an intermediate frequency band signal for transmission over the LAN wiring.

Abstract
A device, network and method wherein a standard wireless modem is coupled to wiring for carrying a wireless baseband signal that may be OFDM based, and may be directly generated by the wireless IF modem, or extracted from the modem RF signal. The wiring may be a building utility wiring, such as telephone, AC power or CATV wiring. The baseband signal is carried simultaneously with the utility service signal over the utility wiring using Frequency Division Multiplexing. The device may be enclosed with a data unit, a standalone dedicated enclosure, within an outlet or as a plug-in outlet adapter. Data units may couple the device by a wiring port such as standard data connector, or via wireless connection. The device may be locally powered or via a power signal carried over the wiring.
