Rosum Corporation and Siano Take GPS Indoors Using TV Signals

Mon, 03/01/2010 - 9:23am
SUNNYVALE, Calif., March 1 /PRNewswire/ -- Rosum Corporation announced today the launch of ALLOY™, a revolutionary location and synchronization solution for indoor and urban environments. The ALLOY™ chip, which was developed in partnership with Siano, the leading supplier of Mobile Digital TV receiver chips for handsets, laptops, PNDs, and other mobile devices, utilizes broadcast TV signals to provide precise frequency, timing and location information.

The breakthrough chip opens up a multitude of new commercial opportunities by enabling femtocell synchronization and location, tracking of people and assets, and localized advertising over mobile TV devices in deep indoor locations such as shopping malls, hotels, campuses and factories with seamless delivery leveraging broadcast TV signals.

Until today, there was no single location solution that worked across all environments. Traditional positioning systems are satellite-based, designed for outdoor applications and have limitations both indoors and in urban environments. The ALLOY™ client combines the ALLOY chip with a high-sensitivity A-GPS chip into a tightly-coupled hybrid TV-GPS solution which works across all types of environments: rural, suburban, urban, and indoor.

Broadcast TV signals enjoy a 100,000x power margin advantage over GPS, and this extends location and synchronization capabilities deep into buildings and urban environments.

According to Dominique Bonte, Practice Director, Telematics and Navigation, for ABI Research, the market for wireless location-based applications is expected to reach $14.5 Billion in 2014.

"The success of these applications will depend on the pervasive availability of the location technologies that enable them. Alternative positioning technologies such as ALLOY are critical (in addressing the limitations of GPS)."

"Femtozone location based applications provide an enhanced value proposition in addition to the voice and data services which are being currently rolled out. By 2014, ABI Research expects 40 million unit shipments for femtocells.

Applications of ALLOY include femtocell synchronization and location, indoor and urban tracking of people and assets, and location-based services and advertising for mobile TV devices.
