Patent ID: 8325693

Claim:
A system carrying concurrently a LAN signal in a LAN frequency band and a radio frequency signal in a first intermediate frequency band different from and non-interfering with, the LAN frequency band over LAN wiring in a building, the system comprising: a first device and a second device connected by the LAN wiring; the first device including a high pass filter, connected to the LAN wiring and passing only signals in the first intermediate frequency band to a first signal frequency converter, the first signal frequency converter converting the radio frequency signal in the first intermediate frequency band received from the LAN wiring to a radio frequency band signal for transmission through an antenna to a wireless terminal and converting a radio frequency band signal received though the antenna from the wireless terminal to a first intermediate frequency band signal for transmission over the LAN wiring; the first device further including a low pass filter connected to the LAN wiring and passing signals in the LAN frequency band to a first network device connected to the first device; and the second device including a high pass filter, connected to the LAN wiring and a network interface adapted to the second device to an external network; wherein the high pass filter passes only signals in the first intermediate frequency band between a processor and the LAN wiring and the processor converts the radio frequency signal in the first intermediate frequency band received from the LAN wiring to a network signal and converts a received network signal from the external network to a radio frequency signal in the first intermediate frequency band signal for transmission over the LAN wiring.
