W3C Geolocation API
The W3C Geolocation API is an effort by the World Wide Web Consortium (W3C) to standardize an interface to retrieve the geographical location information for a client-side device. It defines a set of objects, ECMAScript standard compliant, that executing in the client application give the client's device location through the consulting of Location Information Servers, which are transparent for the application programming interface (API). The most common sources of location information are IP address, Wi-Fi and Bluetooth MAC address, radio-frequency identification (RFID), Wi-Fi connection location, or device Global Positioning System (GPS) and GSM/CDMA cell IDs. The location is returned with a given accuracy depending on the best location information source available.
== Deployment in web browsers ==
Web pages can use the Geolocation API directly if the web browser implements it. Historically, some browsers could gain support via the Google Gears plugin〔(【引用サイトリンク】title=Geolocation API: Gears API: Google Code )〕 but this was discontinued in 2010 and the server-side API it depended on stopped responding in 2012.〔(GeolocationAPI - gears - Provides the geolocation of a device running a Gears-enabled web browser. - Improving Your Web Browser - Google Project Hosting ).

The Geolocation API is ideally suited to web applications for mobile devices such as personal digital assistants (PDA) and smartphones. However, there is not yet widespread support on such platforms due to the wide variety of devices and mobile browsers, which usually lack a plugin architecture. On desktop computers, the W3C Geolocation API works in Firefox since version 3.5, Google Chrome,〔(【引用サイトリンク】title=A new Chrome stable release: Welcome, Mac and Linux! )〕 Opera 10.6, Internet Explorer 9.0, and Safari 5. On mobile devices, it works on Android (firmware 2.0 +), iOS, Windows Phone and Maemo. The W3C Geolocation API is also supported by Opera Mobile 10.1 — available for Android and Symbian devices (S60 generations 3 & 5) since November 24, 2010.〔(【引用サイトリンク】author=Opera.com )〕
Google Gears provided geolocation support for older and non-compliant browsers, including Internet Explorer 7.0+ as a Gears plugin, and Google Chrome which implemented Gears natively. It also supported geolocation on mobile devices as a plugin for the Android browser (pre version 2.0) and Opera Mobile for Windows Mobile. The Google Gears Geolocation API is incompatible with the W3C Geolocation API.
