Unfortunately, most IT managers are not equipped with the technical background you posses, nor do they have the time to thoroughly evaluate the various vendor solutions. Hence, I am working on a research report that will help the IT manager/Architect make sense of these solutions. Thanks Devin.

They even referenced a page of goo in a new book-of-RF-formulas. Then, they released a YouTube video, additional whitepapers, etc showing that ClientLink works through direct line-of-sight (which limits it to 3dB and isn't really beamforming at all). I posted a comment on that video, and they immediately made it private so that I could no longer see or access it. Not really sure what they're trying to hide, but they sure are hawking this "technology" to their VARs and customers. :( Cisco tried to sell me on the fact that in an indoor environment you could exceed 3dB gain because of all of the reflections.

Now they just need a viable solution with external antennas. I think the interesting part of this announcement is that Cisco tries to make this a technology announcement and the only real technology is ClientLink, and even that is a bit dubious. With 2 transmit chains beamforming can only give 3db gain, this doesn't really make up for the fact that all of Cisco's competitors have 3 transmit chains and CDD which can provide more than 3db gain over Cisco. As you correctly point out, it is going to be more and more difficult for the IT buyer to differentiate solutions as there is more and more innovation on the RF side. In the end I believe that this will lead to enterprises using benchmarking to compare solutions, much the way companies do when evaluating other IT solutions.
