ABSTRACT:
Systems, methods and apparatus for improving the coverage of a wireless network based on 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. The frequency shifting may make use of a conventional frequency shifting schemes such as mixer/filter and heterodyne. In one embodiment the wireless signal is frequency shifted by converting it to other representing signals (such as I/Q components) and forming the frequency-shifted signal from the representations. The system is may be used to increase in-door or outdoor coverage, as well as bridging between in-door and outdoor networks. 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. Methods and other systems with different advantageous configurations are also described. This abstract is not intended to limit or construe the scope or meaning of the claims.
