Apparatus and method for frequency shifting of a wireless signal and systems using frequency shifting
First Claim
1. A network for wireless communication of a wireless signal in a wireless frequency band between at least one first wireless unit and a plurality of second wireless units, said network comprising:
- a plurality of distinct wired mediums for interconnecting the first and second wireless units, the wired mediums providing a wired frequency band distinct from, and lower in frequency than, the wireless frequency band, each wired medium having first and second ends;
a center device coupled to the at least one first wireless unit and connected to the first end of each of the wired mediums, said center device being operative to frequency shift the wireless signal between the wireless frequency band and the wired frequency band, and said center device being further operative to couple the at least one first wireless unit to each of said wired mediums; and
a plurality of remote devices, each connected to a second end of a respective one of said wired mediums and each coupled to a respective one of the plurality of second wireless units, each of said remote devices being operative to frequency shift a signal between the wireless frequency band and the wired frequency band, wherein;
said network is operative to allow said center device to receive the wireless signal in the wireless band from the at least one first wireless unit, to down frequency shift the wireless signal to the wired frequency band, and to transmit the shifted wireless signal to all connected wired mediums;
each of said remote devices is operative to up frequency shift the shifted wireless signal from said center device to the wireless frequency band, to reconstruct the wireless signal, and to transmit the reconstructed wireless signal to the respective one of the plurality of second wireless units;
said network is operative to allow one of said remote devices to receive a wireless signal in the wireless band from the one of the plurality of second wireless units coupled thereto, to down frequency shift the received wireless signal to the wired frequency band, and to transmit the shifted wireless signal to the connected wired medium; and
said center device is operative to up frequency shift the received shifted wireless signal to the wireless frequency band to reconstruct the wireless signal, and to transmit the reconstructed first wireless signal to the at least one first wireless unit.

Abstract
Network providing improved coverage based on a frequency shifting scheme. A wireless signal in a frequency band is shifted to another distinct band, and carried in the shifted band, using wired or wireless mediums, to another location, wherein the wireless signal is shifted back to the original frequency band. In one embodiment, the wireless signal is frequency shifted by converting it to other representing signals and forming the frequency-shifted signal from the representations. The medium may use dedicated wiring or existing service wiring in a residence or building, including LAN, telephone, AC power and CATV wiring. The system (in whole or in part) may be enclosed as a stand-alone unit, housed in integrated form as part of a service outlet or as a snap-on/plug-in module.
