Aruba, Cisco and Trapeze wireless LANs

I've been trying to find out more about how local LANs around a VSAT might be set up and managed and found this page:
https://www.trapezenetworks.com/news/pressreleases/?NewsId=133

It is by Trapeze, so emphasises their merits and compares with Cisco and Aruba alternatives.

Quote "In the small business configuration comprising 10 access points and 250 users, the Yankee Group found that a WLAN built around the Trapeze Networks MX-8 controller provided the lowest TCO, with first year costs of $23,367 "

I guess most VSAT community networks might have rather less than this, with between 1 and 5 wireless access points and with 10 to 100 users.

If you have experience with any of these alternatives (or others) please say.

Cardiff University is implementing a Trapeze Ringmaster LAN with 1300 access points and 35000 PCs.  This is 200 - 1000 times the size of what we are looking for, but what lessons can we learn ?  ref: https://news.thomasnet.com/companystory/523903
