1. A local area network for data communication, sensing, and control comprising at least three serial intelligent cells interconnected exclusively by electrically-conducting media into at least two communicating pairs, wherein:

  • (a) each of said electrically-conducting media physically interconnects no more than two of said serial intelligent cells;

    (b) each of said at least one communicating pair includes one of said electrically-conducting media and exactly two of said serial intelligent cells;

    (c) each of said at least one communicating pair engages in a full duplex communication exclusively over said electrically-conducting media; and

    (d) each of said at least one communicating pair is operative to engage in said communication bidirectionally and independently of the communication of any other of said at least one communicating pair;

    wherein at least one of said electrically-conducting media includes electrical power wiring of a building;

    wherein at least one of said electrically-conducting media is used to carry both local area network data and electrical power; and

    wherein the local area network data and electrical power are combined using frequency-domain multiplexing.
