Abstract
A method and device for communicating over a power line is provided. In one embodiment, the device includes a multiband media access control (MAC) layer configured to select one of a plurality of frequency bands for communication and a multiband physical layer configured to communicate directly with said multiband MAC layer and to communicate over the power line via any one of the plurality of frequency bands. The multiband MAC layer may include a power control module configured to provide information to said physical layer to control the transmission power of data transmitted by said physical layer and a modulation control module configured to select one of plurality of modulation schemes for data transmitted by said physical layer. The physical layer may include a plurality of physical drivers with each physical driver configured to transmit and/or receive data in a different one of the plurality of frequency bands.
