HomePlug AV2

Posted by Sam Churchill on

The HomePlug Powerline Alliance today announced the HomePlug AV2 specification, designed to meet the expanding requirements of the connected digital home. The AV2 specification claims to deliver a 5x increase in performance over current HomePlug AV solutions and offer significant improvements in whole home coverage.

The new spec enables reliable delivery of multiple streams of 1080p HD video and broadband Internet, says the organization. Current estimates state that it will around 600 Mbps. HomePlug AV2 is fully interoperable with the original HomePlug AV standard (pdf) and will be brought into the IEEE P1901 standard.

The HomePlug 1.0 specification was released in June of 2001, which was followed by HomePlug AV in 2005, and HomePlug Command and Control in 2007.

“More than 50 operator/service providers have deployed HomePlug AV powerline networking solutions as a means to expand services,” said Kurt Scherf, vice president, principal analyst, Parks Associates.

Major powerline enhancements in the developing HomePlug AV2 specification include:

  • MIMO (Multiple-Inputs Multiple-Outputs): For significant increases in link throughput and range. MIMO allows the data signal to propagate from multiple outputs to multiple inputs and enable more reliable and expanded home coverage.
  • Increased MAC (Medium Access Control): Lower overhead and expanded throughput.
  • Increased operating spectrum: The specification will expand operations into an additional spectrum, up to an order of magnitude beyond current powerline technology.
  • Extending coverage: Can use repeating and routing technology in networks of three or more nodes.

The HomePlug AV2 specification is expected to deliver a 5x increase in performance over current HomePlug AV solutions at the application layer to offer significant improvements in whole home coverage. These advancements are necessary to meet the increasingly demanding Quality of Experience (QoE) requirements of service providers and consumer electronics companies.

HomePlug’s Technical Working Group conducted extensive international field testing and channel characterization and simulations. HomePlug plans to finalize the specification in the first quarter of 2011.

Last year, the number of U.S. households using Web-connected game consoles rose by 64% from 2008, while the number of households connecting a PC to a TV increased by 36%, according to Parks Associates. iSuppli also found that Internet-enabled TVs are the leading and fastest-growing approach to accessing the Web on television. InStat predicts over one-half billion web-enabled consumer electronic devices in operation by 2013
