Existing infrastructure is 1130AG with A radios turned off - all autonomous and no wireless controller. What issues do I need to be aware of? We haven't made a decision as to a particular model (may not even be Cisco at this point), and I have yet to see an N WAP so forgive me if some of these questions seem simple.
I'm looking at adding 802.11n WAPs in a few areas that need increased bandwidth - conference and training rooms, and presentation areas.
Do all N WAPs support both 2.4 GHz and 5.0 GHz range, or does that need to be specified when ordering? I've seen some of the cheaper models that only list 2.4 GHz as the operating frequency and some that don't even specify a frequency.
Do the N WAPs become degraded if non-N clients associate? If so, is there a way to prevent non-N clients from associating? Some of these areas already have existing WAPs, so I need to determine if its okay to replace existing, or if these new WAPs will cause problems - both will be using the same SSID and authentication methods.
Or, am I better off using N in the 5 GHz space? Other than 1 or 2 Mac users, I'm not aware of any clients currently running N, so I don't know if they will support N at both 2.4 or 5.0, or if that is even an option. Do all N adapters automatically support both? Our previous testing with A in the 5.0 GHz range was not very satisfying, so I don't know if the range issue has been addressed in 802.11n.
