HomePlug

A powerline network that is designed to run Ethernet over the existing electrical system and use AC wall outlets as connecting points. HomePlug provides a non-wireless alternative to stringing network cables to all the rooms in the house. It is very often used with an existing, wired Ethernet network to connect a computer in a distant room without going wireless. All computers and network devices (routers, switches) plug into HomePlug adapters, also known as "HomePlug bridges," that plug into the wall outlet.

HomePlug 1.0 and HomePlug AV
HomePlug 1.0 provides an effective data rate of 8.2 Mbps, while HomePlug AV (HPAV) offers quality of service (QoS) and 150 Mbps for video streaming. Both versions use OFDM modulation and the CSMA/CA access method used in wireless Ethernet (802.11).

HomePlug transmits low-energy signals in the 4.5MHz to 21MHz frequency range, way above the 60Hz and 50Hz of AC power. HomePlug AV uses 2MHz to 28MHz. For more information, visit the HomePlug Powerline Alliance at www.homeplug.com. See powerline network. See also HomePNA.
