Performance study of LANs that use intra-building power lines for data transmission

Abstract

Intra-building power lines provide a readily available channel for LANs (Local Area Networks) communications within a building. However, power lines, which were not designed for data communications, are found to suffer from high and unpredictable variations in impedance, signal attenuation and noise. To overcome noise, especially impulse noise, the report recommended that a direct sequence spread spectrum encoding technique be used in the power line transceiver design.
