Skyhook Wireless has announced the launch of its Wi-Fi Location Service (WFS), an alternative to GPS that maps a client's location by triangulating against 802.11 access points.
Skyhook promotes its service as more effective than GPS in congested urban areas, where tall, tightly packed buildings can block GPS signals. Among its potential uses, according to Skyhook, are E911 location, enhanced driving directions, and asset tracking when coupled with RFID tags.
Skyhook has mapped 25 major US cities, and plans to increase its coverage to 100 US cities and select European cities by year's end.
