Influence of load impedances on the quality of Power Line Communication

Advanced communication technologies have allowed power-line-communication (PLC) channel to be a transmission medium that enables the transfer of high-speed digital data over the classical indoor electrical wires. The development of PLC systems for Internet, voice, and data services requires measurement-based models of the transfer characteristics of the mains network suitable for performance analysis by simulation. This paper presents the impact of load impedances connected on the electrical network on insertion gain and capacity of the PLC link.
