HomePlug is the name of the specification that defines the home networking technology that connects devices to each other through the power lines in a home (see power line networking). HomePlug certified products connect PCs and other devices that use Ethernet, USB and 802.11 Wi-Fi technologies to the power line via a HomePlug bridge or adapter. Some products have HomePlug technology built-in.
HomePlug uses Intellon's PowerPacket solution as its baseline technology. Intellon created and patented the baseline technology for the HomePlug 1.0 standard and introduced the first HomePlug 1.0-based IC in June 2001.
