We have a school site with 15 x Aruba iap 93's. Users are complaining of slow connection speeds and ipads not roaming well. From the GUI can see utilization is high (60-70%) on a number of APs. Even the APs with only a couple of clients attached are showing high utilization.
Firmware is the latest and the site only has approx 50-60 clients attached at the same time
Could this be just not enough APs ? Would it be worth trying to force the clients to use the 5ghz less conjested range ?
Any help much appreciated....

50 - 60 clients, depending on how much activity each client is doing, could be a little high.
What version of SW are you running? 22.214.171.124?
Is Client Match enabled?
5GHz will, generally, provide cleaner air than 2.4GHz; however, you coverage per AP is reduced. Have you done a site survey to see if you are getting interference from neighboring APs or other non-WiFi devices on 2.4? Not all devices support 5GHz so check the client types that are connecting.

I presume you have high utilization in terms of RF?
Since the IAP-93's are single radio dual band AP's they will operate in the 2.4GHz band only by default. Since 2.4GHz has a very limited spectrum its possible to experience high channel utilization (and possibly noise) in this band.
Is there any reason you have implemented IAP-93's instead of IAP-105's? IAP-105 can do 2.4GHz and 5GHz concurrently. 5GHz has way more spectrum to work with.
If you have overlap in the coverage of these IAP-93's you could possibly configure certain IAP-93's to be in the 5GHz-band, but this is probably not ideal nor practical.
