I believe we have narrowed it down to Aruba, HP Procurve (we use HP switch gear), and Meraki. I have two questions: 1. Are there any hidden costs we should watch out for with any of these (particularly Aruba.) Will we hit major costs other than the up front cost for the APs and the controllers? 2. I know a lot of schools are very happily using Aruba, but I haven't heard of any schools using HP and very few using Meraki. Are there any schools who have gone with Aruba and regretted it? If so, why? Are there any schools out there using HP Procurve (formerly Colubrius) or Merkai? What do you think of them? Did you have any surprises after you deployed?

This should provide a decent access for b/g users and a fast lane for n users. I'm not sure that best effort on b/g will be good enough when you consider devices like Iphones or future Voice over WiFi devices. One aspect of this kind of approach will be the performance of coverage algorithms. n has such a wierd shape compared to b/g or a...I'm a little suspicious as how vendors will deal with n's behavior! As a side note: We are testing in our info-commons (the worse enviroment you can think of...tons of users and tons of APs) 802.11n APs from Aruba and Meru (we have just replaced locations of our existing Proxim APs with the test APs, and those n APs are surrounded by legacy Proxim APs as well) One week with Aruba, one week with Meru.

Philippe Although the issue of co-channel interference is an important one, I think it may be reasonable to assert that its importance will be reduced with the adoption of 5 GHz 802.11n. With over 20 non-overlapping channels, I believe it will be possible to design high-density, micro-cellular WLANs that do not suffer from performance degradation as a resulting of co-channel interference. Over time, I believe 2.4 GHz will be thought of as a best-effort legacy technology for most enterprises.

RE: [WIRELESS-LAN] Deploying 802.11a alongside b/g
In order to service the dense environment adequately in a campus classroom/commons/lecture-hall environment - all available a b/g channels should be used simultaneous in every given Wi-Fi cell. With that being said - it is the station chipset mfg who determines which band a or b/g is selected as default if both are available - you will find that there are many variances here between station vendors. When designing for a - you will need roughly twice (2x) the number of traditional AP's to cover the same given environment (Similar RSSI) - due to significant attenuation impact on 5Ghz over 2.4. If you have all of the intelligence in the edge of the Wi-Fi network (in the AP) - and manage all MAC processing for all AP's in a given area in a single hardware processor - then you can have infinite MAC layer control when associating users and you can then more seamlessly load-balance b/g clients to a radios during that process. Also keep in mind - if line-rate QoS and Encryption are available in your device and processed at the edge (not the controller) - then there is no problem running voice in both bands simultaneously.
