Method for communication channel coordination between nodes, each node including at least one of a transmitter and a receiver, for transmitting and receiving signals over residential electrical cables. The residential electrical cables include at least one active wire, one neutral wire and one ground wire, at least two of the wires forming wire pairs. The method includes the procedures of, for a given one of the receiver, examining the transmitter in each one of the nodes which communicates with the receiver, selecting one of the examined transmitters as a primary transmitter, determining an optimal receive wire pair for the receiver to receive the signals transmitted between the primary transmitter and the receiver, informing all the examined transmitters of the determined optimal receive wire pair, and tracking at least one communication characteristic over the determined optimal receive wire pair.
