I work for the City of Corpus Christi, and -supposedly- we have the largest WiFi network in the world.
Our network currently covers around 200 Sq. miles (fixing to be expanded to 630), and one of the things we are charged with is that "...anywhere you are in the coverage area you can get a 802.11/g connection...". We have roughly 1600 AP's currently, and we needed some way to be able to statistically validate our coverage. In order to do that, we have around 30 of the City maintenance trucks outfitted with tracing equipment which automatically monitor the system as the trucks are driven around the City, and report their statistics to our support server as they go. If the truck ever drives out of the coverage area, the units log where the coverage starts and ends, and sort of tracks the route of the truck so we can tell where the coverage failed.

We are already setting a bunch for them up to act as a active monitoring system [poll the APs, make sure they are alive, grab all data, send it all to a server to analyze it]. Sounds very similar to your system in fact. The "war driving" part is more of an exercise in mapping our coverage and range. Before I tell boss man to grab one of these GPS systems I want to make sure I have this right: I should be able to connect it via the Serial port on the back of my net4526-20 if the unit says it is serial Thanks On Mon, 2007-04-30 at 15:16 -0500, David Dudley wrote: > War Driving, huh ;-) > > We have a number of the net4801's in the field running kizmet and > NetBSD with a gps device that talks over the internal serial port. > > The gps's were provided by a contractor, and I've never been able to > get a model number from them that I can cross ref.
