1. A method for communication over a network of power lines, comprising:

  • establishing a communication link within a selected frequency band over the network of power lines between a first transceiver coupled to the network and a second transceiver coupled to the network; and

    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 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.
