20 Unifi AP's here, full site coverage, works like a dream!
Full coverage here with a managed wireless system - UniFi. >90 APs currently.
Full coverage with a managed ARUBA System. 18APs inc an external aerial
Part coverage, LEA support them.
Cisco 54G blanket wireless... Motorola "hotspots" for N coverage in a few places, no public WiFi.
Thanks for all the replies and votes. Very interesting to see the difference.
Just to add, we have quite good coverage in our main buildings and boarding houses but they are self managed plus we manually setup students own devices (currently about 300 units)
