If you are using a linux system, you can get the information by looking at
/proc/net/wireless, or by running iwlist scan.
If you're running mac os, there's a command line program for doing
wirelessy things -
/System/Library/PrivateFrameworks/Apple80211.framework/Resources/airport
You can scan for access points by running airport -s . This will give list
the access points with their signal strength.
Extra information is available if you run airport -s -x , which returns an
xml .plist file.
There is a man page. It's special.
You might want to write extra code to automatically generate a critical
ticket with the networking department if the signal strength drops below a
justifiable-to-management level. NOC based monitoring may improve soon
thereafter.

Hi,
Is there an automated way of monitoring (and notifying) when a wireless
network goes down? I'm looking for something like Nagios, but for wireless
(or can Nagios do this too?)
I don't manage our network--our ITS department does. They seem to think
it's adequate that I'm the monitoring system but I'm finding this extremely
frustrating.
Nagios can monitor *anything* so long as you can write a script that'll
get you some status back.
If you have a command line way of getting signal strength for the network,
that'd likely be best, but you could also just test to see if you can ping
out on the right interface.
