I can not speak to WPA, I'm not sure I know that protocol, but if have a 
cell phone that that can do HTTP GET requests to a server, you can 
trivially write a php page the gets the url and writes the fields to a 
database and have mapserver display that. So that is pretty real-time.

So you phone would ping a url like 
http://yourserver.com/track.php?lat=<lat>&lon=<lon>&device=<uid>&...

And then write a track.php to fetch the paramaters and stuff them into 
the DB.
