SiRF Teams with Skyhook to Deliver GPS-WiFi Hybrid Positioning

February 9, 2007

The technology will be applied to SiRF's client software for mobile handsets, which synthesizes GPS and WiFi measurements, and to SiRF's SiRFLoc Server to enable it to establish precise positioning from the measurements.


SAN JOSE, CA and BOSTON /PRNewswire-FirstCall/ -- SiRF Technology Holdings Inc., a leading provider of GPS-enabled silicon and premium software location platforms, and Skyhook Wireless Inc., provider of the Wi-Fi Positioning System (WPS), announced that SiRF has licensed the WPS to create a single positioning system for wireless carriers that combines the best of both GPS and WiFi technologies. The system, which is scheduled for release as part of SiRF's Multimode Location Platform later this year, promises to boost the availability and adoption of location-based services. The two companies will present a demonstration of the new hybrid GPS-WiFi location technology at the 3GSM World Congress 2007 being held February 12-15 in Barcelona, Spain.

The technology will be applied to special client software from SiRF for mobile handsets that synthesizes GPS and WiFi measurements, as well as to SiRF's SiRFLoc Server to enable it to establish precise positioning from these measurements. As handset makers roll out a new generation of WiFi-enabled mobile phones to enhance both data and voice communications, the SiRF-Skyhook hybrid technology will leverage this hardware ecosystem to provide greatly enhanced positioning availability and accuracy for location-based services. Using this new technology, carriers can boost their revenues by offering enhanced location-based services that are easier to use; handset makers can better differentiate their products; and application developers can create exciting new services that work anywhere, even when GPS signals are not present. The system will benefit consumers by enabling them to more quickly and reliably perform tasks such as planning a trip, finding friends nearby, or locating the closest ATM machine.

"Our strategy is to enhance consumer experience with location-enabled content and services by combining multiple sensors and signals to provide accurate location information everywhere. This is the first time a single positioning system has combined both GPS and WiFi location data to get us a step closer to achieving 100% availability of accurate positioning," said Kanwar Chadha, co-founder and vice president of marketing for SiRF. "By complementing our industry-leading GPS performance with Skyhook's WiFi positioning in our Multimode Location Platform, SiRF is continuing to broaden its product line and pursue its mission to bring the benefits of location awareness to mainstream consumers."

SiRF will be offering the new technology to mobile handset makers using SiRF's SiRFstarIII and GSCi-5000 chips sets, as well as to wireless carriers using its SiRFLoc Server, a carrier-class, standards-compliant, multimode assisted-GPS location server that incorporates SiRF's patented multimode technology. Any SiRF-based mobile handset with a WiFi radio subsystem built in will be able to take advantage of the new technology by including the client software.

"This partnership creates an availability breakthrough for location-based services, offering handset makers and carriers a new hybrid GPS-WiFi technology for anytime, anywhere location reliability," said Ted Morgan, founder and CEO of Skyhook Wireless. "WiFi and GPS are ideal complementary technologies for mobile handsets, enabling a more comprehensive location solution and a more robust infrastructure for exciting new location-based applications."
