SiRF teams with Skyhook Wireless to deliver GPS-Wifi hybrid to accelerate location-based services

San Jose, USA, 9 February 2007 – SiRF Technology Holdings, Inc., a provider of GPS-enabled silicon and premium software location platforms, and Skyhook Wireless, Inc., provider of the Wi-Fi Positioning System (WPS), has announced that SiRF has licensed the WPS in order to create a single positioning system for wireless carriers that combines the best of both GPS and Wi-Fi technologies.

This 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/Wi-Fi 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 Wi-Fi 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 Wi-Fi-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 Wi-Fi location data to get us a step closer to achieving 100 percent availability of accurate positioning,” said Kanwar Chadha , Founder and Vice President of Marketing for SiRF.

SiRF will be offering the new technology to mobile handset makers using SiRF SiRFstarIII GPS chip sets and 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 Wi-Fi radio subsystem built in will be able to take advantage of this new technology by including the client software.
