Hi all
Feedback from my Aruba SE is as follows.
The AP228 lets you break out the 2.4GHz and 5Ghz radios independently.
This can be done, but I had one or two people express reservations about this type of solution from support perspective.
A good suggested alternative was the following:
AP 367 for P2P
AP 305\207 for coverage for clients
Cost wise it is probably the same as 228 but offers a much better solution to the customer as in Clients get 5Ghz coverage also
