    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!

Cisco – 802.11n shootout with Aruba,Motorola and HP

I just stumbled on a 4 part youtube video I believe posted by Cisco on a side by side “shootout” of 802.11n performance testing between Cisco, Aruba, Motorola and HP, 802.11n offerings. Their testing was conducted in a greenfield environment and deployed various tools to monitor performance. Cisco came out smelling like a dozen roses (no, let me take that back, 2 dozen roses) as they conducted the test themselves. But needless to say, I think there is value in watching the videos. They have a solid test approach with added real world examples, or should I say test samples.

HP took two black eyes and a bloody nose in these videos. Gezzz…

Btw, I would hate to be the poor soul sitting underneath that 1252 access point hanging from the t-bar.
