   The last I checked this process was years ago, but what the process was, as   
   I recall, was you first get a free key from Google.   
      
   Then you use that key to query an online database of BSSID location   
   information that Google provides to all free of charge.   
      
   As a rudimentary security measure that I doubt Google Maps has to follow,   
   you have to give it TWO BSSIDs which must be in close proximity to each   
   other in the Google database, and a signal strength (which can be bogus).   
      
   Under those circumstances, as I recall, Google will give you the location.   
      
   But all that only works if you're already on the net, which is not possible   
   for a tablet that has no cellular capability and which is driving down the   
   road (unless it's fleetingly connecting to unsecured wide-open access   
   points).   
      
   Hence the question is how does Google /still/ know your location?
