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.
