Others have already covered most of the same ground I would on collecting SNMP
data sets and actively looking where users are stubbornly sulking ("why didn't
anyone fix this problem I didn't tell anyone about!?"), but if you have at
least a little budget and some time you could put a decent system together
yourself. Most of the fancy tools out there aimed at this problem like
7signals and NetBeez are just fancy agents running on Raspberry Pis. If I
were in your situation, and wanted to gather hard data, here's what I would do:
* Get hold of a few of them, and set them up in some of your higher profile
locations (libraries, student centers, larger classrooms, etc) with a wireless
adapter
* Use a wired connection for backhaul and management. If you can put them
on a PoE port, you can get a splitter that will allow you to power the Pi off
of PoE, making deployment a little simpler.
* Use a combination of smokeping and regularly scripted iperf tests, dumped
into something like graphite. Throwing in some tests for common services
(school web site, email, etc) wouldn't hurt either.
These can give you some hard metrics on latency and throughput, which can go a
long way in figuring out whether wireless complaints are really about
wireless, or something else in the chain.

have any ideas/formulas to try to calculate something like this? Thanks for
any ideas that you care to share.
