That's a fine combination for business, as it promises the chance to serve users with fewer access points than are required today
I doubt it. At our place (and I suspect many others) the issue that jacks up the number of APs is signal propagation. We have locations where we have an AP per room or two (which may only have one or two people per room) to get decent coverage. All this fancy high speed tech won't help the signal propagation - in fact it'll probably hinder the propagation even more.
The places that will benefit are more likely to be large, high density communal areas. (e.g. Canteens, lecture theatres, etc)
