    Shawn Jackman (Jack) CWNE#54 is a personal friend and has been a mentor to me for many years.  I've had the pleasure and opportunity to work with Jack for 4 years. Jack is a great teacher who takes complex 802.11 standards and breaks them down so almost anyone can understand the concept at hand. I'm excited for you brother. Great job and job well done! Put another notch in the belt!

Article Excerpt:

 

Geo – “Another ratified standard indirectly related to wireless this week. Those of us who have used the Cisco 1252 “brick” access points know these puppy’s require the additional power also known at 802.3at, when running both radios.  “

http://www.my80211.com/home/2009/9/14/8023at-2009-power-over-ethernet-poe-plus-standard-ratified.html

The IEEE recently ratified 802.3at, a new Power over Ethernet Plus standard. The IEEE 802.3at-2009 Power over Ethernet (PoE) Plus standard defines the technology for powering a wide range of powered devices at up to 25W over existing CAT5e and above cables.

Mike McCormack, Chair of the IEEE P802.3at Task Force said, "IEEE 802.3at uses the Link Layer Discover Protocol (LLPD) from IEEE Std 802.1AB, which allows dynamic power allocation and negotiation down to 1/10th of a Watt, and associated technology including Type, Length, Values (TLVs) from IEEE 802.3bc, which was also recently approved. This will allow equipment manufactures to manage their power supply costs and efficiencies at levels not possible with previous standards, and to cut their costs in the process."
