Abstract
Communication apparatus, comprising: a network of power lines; and first, second and third transceivers, coupled to the network, the first transceiver being adapted to transmit a first signal over the network to the second transceiver within a selected frequency band at a transmission power level sufficiently strong that the first signal can be decoded by the second transceiver, but is attenuated sufficiently when it reaches the third transceiver 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.
