Abstract:
1. A multi-tone modem with a plurality of shared and discrete components forming a transmit path and a receive path configured to couple to an alternating current (AC) power line wired communication medium to communicate at least one multi-tone modulated communication channel thereon, and the multi-tone modem comprising: at least one multi-tone modulator component configured for multi-tone modulation and demodulation of a transmitted and received communication channel at a base band frequency range; at least one configurable frequency up converter component coupled to the multi-tone modulator to selectably up convert the frequency range of the transmitted base band signal from the at least one multi-tone modulator to that of a selected communication band and down convert received signals from the selected communication band to the base band for demodulation by the multi-tone modulator, thereby allowing the multi-tone modem to support communications on at least any selected one of a plurality of frequency bands supported by the power line; and a line interface for connecting to the power line through an AC power socket.
