==Implementation==

Though the implementation is not specified, W3C Geolocation API is built on extant technologies, and is heavily influenced by Google Gears Geolocation API. Example: Firefox's Geolocation implementation<ref>{{cite web |url=https://support.mozilla.org/en-US/kb/does-firefox-share-my-___location-websites?redirectslug=does-firefox-share-my-___location-web-sites&redirectlocale=en-US|title=Does Firefox share my ___location with websites? {{!}} Mozilla Support|work=Mozilla Firefox|author-link=Mozilla Firefox|publisher=Mozilla|date=n.d.|access-date=2021-04-21}}</ref> uses Google's network ___location provider.<ref name="code-google-gear-geo-api">{{cite web |url=https://code.google.com/apis/gears/geolocation_network_protocol.html|url-status=dead|archive-url=https://web.archive.org/web/20151222162645/https://code.google.com/p/gears/wiki/GeolocationAPI|title=GeolocationAPI - gears - Provides the geolocation of a device running a Gears-enabled web browser. - Improving Your Web Browser - Google Project Hosting|work=Google Code|archive-date=2015-12-22|date=n.d.|access-date=2021-04-21}}</ref> Google Gears Geolocation works by sending a set of parameters that could give a hint as to where the user's physical ___location is to a network ___location provider server, which is by default the one provided by Google (code.l.google.com).<ref>{{cite web |url=http://webscannotes.com/?page_id=425|url-status=dead|archive-url=https://web.archive.org/web/2014042118490720121112035756/http://webscannotes.com/geolocation-api/|title=WebScanNotes.com: W3C Geolocation API|work=WebScanNotes|date=n.d.|archive-date=2012-0311-0612|access-date=2021-04-21}}</ref> Some of the parameters are lists of sensed mobile cell towers and Wi-Fi networks, all with sensed signal strengths. These parameters are encapsulated into a JavaScript Object Notation ([[JSON]]) message and sent to the network ___location provider via HTTP POST. Based on these parameters, the network ___location provider can calculate the ___location. Common uses for this ___location information include enforcing access controls, localizing and customizing content, analyzing traffic, [[contextual advertising]] and preventing identity theft.<ref>{{cite web|url=https://papers.ssrn.com/sol3/papers.cfm?abstract_id=1622411|ssrn=1622411 |title=Personal Jurisdiction, Internet Commerce, and Privacy: The Pervasive Legal Consequences of Modern Geolocation Technologies|first=Kevin F.|last=King|date=2010-06-08|publication-date=2010-06-09|access-date=2021-04-21}}</ref>
