Patent ID: 7970374

Claim:
A network interface device comprising: a first block including a first Physical (PHY) layer in communication with a first Media Access Control (MAC) layer, the first block configured to implement a first wideband communication technology associated with a first wideband frequency range; a second block including a second PHY layer in communication with a second MAC layer, the second block configured to implement a second wideband communication technology associated with a second wideband frequency range that is separate from the first wideband frequency; a data distribution block in communication with the first and second MAC layers and configured to receive and distribute the data to the first and second blocks; a coupling/decoupling stage configured to couple signals within the first and second wideband frequency ranges onto an Alternating Current (AC) power line; a first analog passband filter disposed between the first PHY layer and the coupling/decoupling stage and configured to attenuate signals with frequencies outside of the first wideband frequency range; and a second analog passband filter disposed between the second PHY layer and the coupling/decoupling stage and configured to attenuate signals with frequencies outside of the second wideband frequency range.
