ABSTRACT:
A home area network system and method uses existing plain old telephone system (POTS) wiring to network computers in a home without disrupting conventional telephone services. The home area network assigns a network address to each computer coupled to the network and communicates using a broadband communication method occupying the portion of the spectrum above the baseband portion used by ordinary telephone service. The home area network employs quadrature phase shift keying (QPSK) modulation on unshielded twisted pair (UTP) wiring arranged in an arbitrary topology. The home area network additionally employs adaptive equalization for each computer pair coupling as well as adaptive error correction.
