The Ethernet Alliance has announced that the IEEE P802.3at task force has created IEEE P802.3at/Draft 3.0 and has submitted it to the IEEE 802.3 working group ballot for technical review of the draft standard. This task force expects to complete standard ratification by 2009.
The IEEE 802.3 working group created the PoE Plus study group in November 2004 to evaluate the technical and economic feasibility of providing increased power to devices over Ethernet, and 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 24W of power using Category 5 cables.
IEEE Std. 802.3af-2003 (Power over Ethernet) helped consolidate voice and data services using a converged network infrastructure, giving customers enormous savings and greater capabilities from their networks. PoE Plus promises to add video services in the same converged networks such as those requiring high-end, pan-tilt-zoom video cameras.
