HomePlug
Résumé
HomePlug is the family name for various power line communications specifications under the HomePlug designation, each with unique capabilities and compatibility with other HomePlug specifications.
Some HomePlug specifications target broadband applications. For instance in-home distribution of low data rate IPTV, gaming, and Internet content, while others focus on low power, low throughput and extended operating temperatures for applications such as smart power meters and in-home communications between electric systems and appliances. All of the HomePlug specifications were developed by the HomePlug Powerline Alliance, which also owns the HomePlug trademark.
On 18 October 2016 the HomePlug Alliance announced that all of its specifications would be put into the public domain and that other organizations would be taking on future activities relating to deployment of the existing technologies. There was no mention in the announcement of any further technology development within the HomePlug community.
The HomePlug Powerline Alliance was formed to develop standards and technology for enabling devices to communicate with each other and the Internet over existing structure/house electrical wiring.
One of the greatest technical challenges was finding a way to reduce sensitivity to the electrical noise present on power lines. HomePlug solved this problem by increasing the communication carrier frequencies so that the signal is conveyed by the neutral conductor which is common to all phases.
The first HomePlug specification HomePlug 1.0 was released in June 2001. The HomePlug AV (for audio-video) specification released in 2005 increased physical layer (PHY) peak data rates from approximately 13.0 Mbit/s to 200 Mbit/s. The HomePlug Green PHY specification was released in June 2010 and targets Smart Energy and Smart Grid applications as an interoperable "sibling" to HomePlug AV with lower cost, lower power consumption and decreased throughput.
In 2010, the IEEE 1901 was approved and HomePlug AV as baseline technology for the FFT-OFDM PHY within the standard and became an international standard.
