Lost in the city without GPS? Skyhook Wireless has launched a new Wi-Fi positioning system, (WPS), offering an alternative to GPS for finding exactly where you are.

The WPS database includes the position and unique network card code number for 1.5 million hotspots in 25 US cities. By monitoring several signals at once and using the database to perform a triangulation, WPS software triangulates your exact position.

The software runs on any Wi-Fi enabled laptop, PDA or smartphone. Skyhook claims that, unlike GPS, WPS doesn't suffer from dead spots in built-up areas and it works indoors.
