Power Line Communications (PLC) is used for information exchange over the lines installed for delivering the electrical power. In-home PLC is a technology which delivers telecom services to every corner of a household through already existing electrical wiring. The in-home PLC channel offers multiple signal feed ports as, usually, it comprises of three wires: Phase, Neutral and Protective Earth. The measurements and results presented in this paper shows the impact of load impedances connected to the electrical network on insertion gain and capacity for Multiple Input Multiple Output (MIMO) PLC channel.
