Actually not really for all APs...i have used APs that run on 2.4 and
handles way over 400 concurrent

and anything north of about 200 is virtually unusable at 5Ghz.

sure know APs that do way more than 400 users (although within a single AP
exist a bonded set of APs)

I think it is in the best interests of the region to remove barriers to

Hmm...the thing is HEIs are "arguably" closer to the not-for-profit arena,
so extending this policy to say private sectors may not worth it as they
are making money an should be able to afford as much. Also still in the HEI
line...perhaps extending to Secondary schools may also be good (although i
don't know of a secondary school having such a need in my region)
