There are over 4,000 antenna patterns, with the relative gain of the best
ones up to 10dBi... the magic is though that the AP also uses the patterns
they transmit on to receive on... so the gain is bi-directional instead of
blasting the signal out but not having any mechanism in place for the client
to be heard.  The AP can also selectively put noise in up to a -15dBi
null... which can be helpful.

I would be curious in what indoor environment there isn't multi-path :-)

Anyways, if you have doubts... Tom's Hardware (which is as unbiased as it
gets) did some testing against Cisco and Aruba.  If you want to see the
power of beamforming, I'd encourage you to read this article all the way
through.  It gives a very detailed explanation of the magic behind Ruckus.

Does Ruckus state their antenna gain anywhere? If their "beam forming"  gain
isn't all that much higher than the competition's omni gain then the
performance couldn't be all that much better unless there's noise or multi
path issues.
