The HomePlug® Powerline Alliance Conducts Second Annual "Plugfest" for High Speed Powerline Networking Chipsets

Testing of HomePlug AV Chips Ensures Interoperability and Compliance with HomePlug AV and IEEE 1901 International Powerline Networking Standards

Portland, Ore. - September 14, 2010 - The HomePlug® Powerline Alliance today announced that three different chipset vendors - Atheros Communications, Gigle Networks and SPiDCOM Technologies - are participating in the second annual silicon vendor plugfest for interoperability and compliance testing for the HomePlug AV specification, including compliance with the new IEEE 1901 powerline networking standard. The event is taking place this week in Tours, France with testing performed by the Laboratoire des Applications Numériques (LAN) using advanced testing tools from Spirent Communications plc.

The HomePlug chipset interop plugfest is the world's only testing event for broadband, multimedia-class powerline networking with multiple vendors to help ensure interoperability and compliance with global standards.

"More than 50 million HomePlug chips have been deployed, and that number is expected to reach 100 million by the end of 2011," said Rob Ranck, president of the HomePlug Powerline Alliance. "A robust testing and certification program is essential to ensure multivendor interoperability and provide a reliable foundation for the market. We have the industry's largest broadband-speed powerline testing and certification program and have certified over 215 HomePlug products to date."

HomePlug devices account for more than 80 percent of the world's broadband-speed powerline communications market. The HomePlug standards family includes HomePlug AV for broadband applications such as HD Video streams, HomePlug Green PHY (GP) for smart grid applications, and HomePlug AV2, the next-generation Gigabit-class broadband standard. HomePlug AV, AV2 and GP are fully interoperable with each other and the IEEE 1901 powerline standard.

The alliance works with key stakeholders to ensure all of its specifications are designed to meet the requirements of IPTV service providers, power utilities, equipment and appliance manufacturers, consumer electronics and other important stakeholders. HomePlug operates the leading Compliance and Interoperability Certification Program for powerline networking to help ensure true multi-vendor co-existence and interoperability.
