PoE Plus Draft 3.0 Ready For Technical Review

The Ethernet Alliance announced that the IEEE P802.3at task force has written IEEE P802.3at/Draft 3.0 and submitted it to the IEEE 802.3 working group for technical review. The task force expects to complete the ratification process by 2009.

The IEEE 802.3 working group created the PoE (power over Ethernet) Plus study group in November 2004 to evaluate the technical and economic feasibility of providing increased power to devices over Ethernet. The group approved the creation of the IEEE P802.3at task force in July 2005. The task force has been working with key vendors and customers to deliver a solution for providing up to 30 W of power using Category 5 cables.

The Ethernet Alliance is supporting the IEEE P802.3at task force through its PoE/PoE Plus subcommittee. Subcommittee members promote the benefits and value of PoE and PoE Plus through activities that include interoperability demonstrations, plugfests, technology demonstrations, webinars, and white papers. The PoE/PoE Plus subcommittee plans to hold a plugfest and webinar on PoE Plus this year.

“PoE Plus brings value to Ethernet by enabling key video services such as perimeter security, video conferencing, and video-based IP phones for video collaborations,” said Val Oliva, president of the Ethernet Alliance. “The Ethernet Alliance is proud to support the IEEE P802.3at task force in its process of creating and ratifying the IEEE P802.3at draft standard.”
