Abstract: A method for communication over a network of power lines (34), including establishing a communication link within a selected frequency band over the network between a first transceiver (32B) coupled to the network and a second transceiver (32C) coupled to the network. The method further includes transmitting a first signal over the link from the first transceiver to the second transceiver at a transmission power level that is sufficiently strong that the signal can be decoded by the second transceiver, but is attenuated sufficiently when it reaches a third transceiver (32E) coupled to the network so that the third transceiver can receive a second signal over the network in the selected frequency band substantially without interference by the first signal.

Abstract: A method for communication includes establishing a data link between first and second transceivers (32, 34) over an electric power line (24). A sequence of data packets is received for transmission over the data link, the sequence belonging to a session of a connectionless real-time network protocol. Responsive to a first packet in the sequence, a reliable connection channel for the session is established over the data link between the first and second transceivers. The packets in the sequence are transmitted from the first to the second transceivers (32, 34) over the reliable connection channel.
