    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 - "Don't Forget Spectrum" - DFS Testing

Cisco's short video on DFS and their wireless controller solution. Its a quick video on DFS and client capacity testing taking advantage of DFS UNII-2 Extended. 

 They also take a poke @ Aruba in the process... :P

The CDW price for an Cisco 1140 is $650. The CDW price for an Aruba 105 is $550 - $100 less.
The CDW price for an Aruba AP-120 is $650. You tested a grapefruit to an orange.

If you test the Aruba AP-120 you will find it does support (http://www.arubanetworks.com/product/aruba-ap-120-ap-121-access-points) the full 5 Ghz spectrum and it is half the size of the 1140 ( or 3500 ).

I manage 8 WISMs and a few 5508s with WCS & NCS so I am a Cisco fan but I also help manage a few Aruba 6000s w/Mk3s.

If you are going to do a "bakeoff" at least try to be equal in the products you select , hmmm ?

I can't check until next week - but I looked at some notes and I am pretty sure the Aruba 105 does support the portion of the spectrum you found missing.

It was pretty hard working with a school district who wanted to buy the AP-12x series (about 350 in 15 buildings ) when the Cisco 1250s required more power than any Cisco closet switch could deliver and would require replacing around 40 1 or 2 year old 3560s or adding the power injectors (how do you shut/no shut an AP?) or shutting down one of the radios. They also had 6500s but no Sup720s so they couldn't do Wisms and the 44xx line would have required 4 with no redundancy (5508s weren't out yet and when they did get released they only supported 256 APs so they would have needed 2 of those )

Do you have a graph or video that could help them find the extra money they needed ?
