The new HomePlug wideband PLC arena provides the key advantage of the ‘no-new-wire’ approach to users. High-speed home networks can be created by using the power sockets and wiring infrastructure that already exist in the home.
HomePlug is also an industry-wide alliance (www.homeplug.org
) whose sponsors include STMicroelectronics. The Alliance's mission is to enable and promote rapid availability, adoption and implementation of cost effective, interoperable and standards-based home powerline networks and products. The HomePlug technologies are fully compliant to the IEEE1901 standard for broadband-over-powerline networks (Medium Access Control and Physical Layer Specifications) and offer a complete ecosystem of interoperable technologies ensuring the forward migration path to Gigabit-class service.
There are two major variants within HomePlug standard, and they are interoperable:
• HomePlug GP (Green PHY), which targets ‘smart Grid’ and smart-energy applications
• HomePlug AV (Audio/Video), which is the consumer standard, aimed primarily at home networking.
Recently, the HomePlug Alliance received a letter from the Coordination Office Charging Interface, Carmeq GmbH, representing five German automakers stating that these OEMs had selected PLC IEEE1901 Profile Green PHY (HomePlug GP) as the communication technology between plug-in electric cars and charging stations. GM, Ford and Toyota followed by adopting HomeplugGP shortly after, making HomepluGP the de facto
standard for EV charging.
