No, but it sends out an identifier. When people know where they are (e.g.  
through GPS, or manual tracking of their location) and pick up a  
signalfrom your wifi point, they can add it to a database.

Using triangulation, they should be able to get a pretty accurate fix on  
it if they want one. But equally, with so many wifi points in the world,  
there is plenty of scope for getting a location wrong from time to time.
