Skyhook Wireless developed an original and innovative way to determine geographic location, by using Wi-Fi signals instead of Global Positioning System (GPS). There are certain advantages of using Wi-Fi over the GPS: it has higher accuracy, and it is more energy efficient.
To pinpoint location, Skyhook uses a reference network composed of the known locations of over 700 million Wi-Fi access points and cellular towers. Skyhook’s coverage area includes most major metro areas in North America, Europe, Asia, and Australia. Skyhook’s system can also be used to enhance the capabilities and performance of GPS enabled devices where GPS reception is weak, for example: indoors, downtown, and crowded areas. Skyhook offers a Software Development Kit (SDK), which allows developers to create location-enabled applications. This uses Skyhook’s software-only Hybrid Positioning System on the platform of their choice.
Currently, Skyhook Wireless offers vital features that allow one to enhance marketing efficiency and develop interconnectional techniques such as geo-fencing, location-based reminders, location-control notification, and georeferenced targeting.
