HomePlug Powerline Alliance Adopts France Telecom's Turbo Code

The HomePlug Powerline Alliance, an industry consortium that promotes standards-based powerline communications technologies, will implement a forward error correction (FEC) technology originally developed by France Telecom as part of its HomePlug AV specification. HomePlug AV provides broadband home networking, enabling connectivity and distribution of HDTV, Digital Audio, and Internet access throughout the home via existing power lines.


The advanced preliminary specification for HomePlug AV aims to deliver data rates of up to 200 Mbps to support multiple HDTV streams and the distribution of data throughout a home over existing power lines and at a low price point. The specification will leverage "Turbo Codes" technology licensed from France Telecom.


France Telecom said its Turbo Codes is a form of forward error correction (FEC) that offers power efficiencies approaching the theoretical "Shannon limit." Turbo Codes is also used in other communications standards ranging from cellular telecommunications (CDMA2000 and W-CDMA), satellite (DVB-RCS, CCSD) to broadband wireless (802.16).
