I am planning to replace my campus WiFi from Aruba IAP solution , currently IAP 225 and 325 are part of R&D.
I want to serve atleast 2000 concurrent users by 28 APs (24 indoors and 4 outdoors) , can aruba IAP solution full fill such requirement ? practically ? (i know 255 users per radio not interested in this answer).
i havent found much details about IAP-325 as its newly launched ,can we trust on 325 ?
i have seen 140 users on ruckus 7372 with default settings (not band steering enabled ,no channel fly enabled) .
Can we assume that SINGLE IAP-325 CAN CATER 300 USERS PRACTICALLY OR NOT ?????
any one having practical experience on this
can we say that ruckus is a high density solution and aruba is a solution where more fetures are required ?

We routinely see over 100 users per access point (AP225) in places like libraries and other large gatherings. The 325 is newer and can support 802.11ac wave 2 clients on top of the AP225s performance.
The key to large numbers of users is the applications they use. Web browsing and Email are fairly well-behaved applications that work in congested environments. Bandwidth and delay-sensitive applications like VOIP have more requirements and fewer of those calls can actually occur on a heavily-loaded AP, than a user who is using the web or email.
Long story short: The application decides how many users can be supported on an access point. From an RF, performance and Physics standpoint, for users to receive more throughput, fewer users will need to be on an access point because bandwidth is shared. So you can have 2000 people on 28 access points (that would be like 72/access point), but each person's bandwidth will be shared with 71 other people on the same access point, that is before factoring any interference (hello outdoors) that will undoubtedly bring the throughput down. If you have users streaming video, or needing to do anything that requires good bandwidth, you should improve the performance by adding extra access points. That is the story for all WLAN manufacturers.
We have a high density validated reference guide here; http://community.arubanetworks.com/t5/Validated-Reference-Design/High-Density-Wireless-Networks-for-Auditoriums/ta-p/155578 that mentions how to plan for high density.
