Skyhook Wireless (formerly known as Quarterscope) is a Boston-based company that developed a technology for determining geographical location using Wi-Fi as the underlying reference system. Using the MAC addresses of nearby wireless access points and proprietary algorithms, Skyhook's Wi-Fi Positioning System WPS can determine the position of a mobile device within 10–20 meters. It provides service similar to GPS without GPS hardware and can also integrate with GPS-enabled devices to provide hybrid positioning. Skyhook Wireless claims that with sub-second time-to-first-fix, supposed 10–20 meter accuracy and near 100% availability indoors and in dense urban areas.
Skyhook's database is gathered through wardriving,[1] and includes more than 250 million wi-fi access points and covers 70 percent of population centers in the United States, Canada, Western Europe and selected Asian countries..[2]
Skyhook Wireless offers Loki[3], a free 'virtual GPS' toolbar that automatically integrates a user's location with web content such as Google Maps, Fandango, Weather.com, etc. It has been now replaced by a "Find Me" page on the website, as well as tools and SDK's used for adding location-based data to sites such as WeatherBug.com.
Skyhook announced a partnership to help users in geotagging their pictures.[4]
At the Macworld Conference & Expo in January 2008, Apple CEO Steve Jobs announced that both the iPhone and iPod Touch would use Skyhook's WPS as the primary location engine for Google Maps and other applications.[5] All Apple devices utilized Skyhook's WPS until the iPhone/iPad software 3.2 release in April 2010, which utilized Apple's own location technologies.[6]

[edit] Public SDK
Skyhook offers a software development kit (SDK), which allows developers to create location-enabled applications. This uses Skyhook's software-only Wi-Fi Positioning System on the platform of their choice. The software development kit is compatible with all GPS NMEA applications, and provides excellent accuracy[citation needed] and confidence estimation.
The SDK supports Windows XP, Vista and Mobile, as well as Symbian OS, Mac OS X, and Linux platforms.[7]
[edit] Privacy and hacking
An article[8] written in February 2008 by Terry Stenvold, and published in the summer 2008 edition of the magazine 2600, describes how to use the Skyhook database with an iPhone and a laptop running Linux to identify the location of any router's MAC address. There is an associated YouTube video[9] showing how to trick Skyhook's Location Service: the user searches Google for the router's MAC address, sets his/her laptop to broadcast that other MAC address, and thereby fool their iPhone or iPod Touch's Location Services into thinking it's at the other router's location.
The same exploit was published in April 2008 by a team led by Srdjan Capkun at the Department of Computer Science, ETH Zurich.[10]
A 2008 article[11] exposes the underlying protocol to query the Skyhook database for the physical location of any MAC address.
