Positioning System Uses Wi-Fi, Not Satellites
Skyhook Wireless Monday launched [.pdf] a positioning service that uses Wi-Fi instead of satellites, which it claims will be simpler and less expensive in many environments.
The Wi-Fi Positioning System (WPS) initially is being rolled out in 25 metropolitan areas, the company said in a statement. It enables the monitoring of any Wi-Fi-enabled device such as smartphones, PDAs and laptops, the company said. The client software access a database of more than 1.5 million WLAN access points in the initial 25 coverage areas, which it uses to calculate location within 40 meters, the company said in a statement.
The company said that the old GPS systems required separate hardware and line-of-site access to satellites. Such systems also are unreliable in some urban aras, according to Skyhook. The WLAN-based location system eliminates those problems.
