(U) Wifi-based geolocation has the advantage that it does not require a GPS or cellular
chip on the device - only a common wifi interface. However, geolocation is at the mercy
of the quality of the database. If the database isn't up to date over the entire geographic
region of interest then geolocation results will be poor.
(U) A simple test to determine whether a region has good wifi-based geolocation
coverage is as follows:
1. In the region of interest, open a recent version of the Chrome or Firefox
browser on a machine with a wifi interface and Internet connection
2. Navigate to maps.google.com
3. Click on the 'locate me' button above the zoom slider
4. If prompted, allow the browser to access your location
5. If the map accurately displays your location, then coverage is good
(U) It is worth noting that under the w3c geolocation API the web browser, not the site, is
responsible for resolving geolocations. If you click 'locate me' in google maps on IE9 , a
request will be sent to Microsoft's servers, not Google's. At the time of writing Firefox,
Chrome and Opera all use Google's database.
