Power line communication is the process of allowing Internet, computer network, or cable television signals to use existing alternating current (AC) lines. Leveraging the wiring present in every wall in every home using the HomePlug Standard, power line communication works to solve a variety of cabling issues. Using plug-in adaptors, this process simply uses a different transmission frequency than those generated by AC power, bypassing interference and increasing convenience.
