Alloy Chip Leverages Mobile TV for Location and Synchronization

Rosum Corporation has announced the launch of Alloy, a location and synchronization solution for indoor and urban environments. The Alloy chip, which was developed in partnership with Mobile TV chip-maker Siano, uses broadcast TV signals to provide precise frequency, timing and location information.
Rosum says the 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, using broadcast TV signals for seamless delivery.
Prior to the launch of Alloy, says Rosum, there was no single location solution that worked across all environments, noting that 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 in a hybrid TV-GPS solution which works across all types of environments, including rural, suburban, urban, and indoor. Broadcast TV signals enjoy a 100,000x power margin advantage over GPS, says Rosum, 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. He says: 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).
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. Rosum cites a number of use-case examples. For example, it says, Femtocells require accurate timing, frequency and location for quick start-up, interference management, and E911 (emergency services) location. It notes that competing solutions can require 60-90 minutes or more to start-up and require placement by the window. Alloy reduces this time dramatically (typically to around three minutes) and extends coverage deep indoors, where femtocells are most valuable.
Additionally, says Rosum, tracking service providers require continuous tracking across all environments outdoor, indoor, and urban.  High-value assets and people tend to be indoors or in urban areas where GPS signals are often unavailable, but TV signals are abundant, enabling Alloy to continue to monitor assets and people in areas where GPS-based solutions fail.
Finally, says Rosum, Alloy can be used to deliver location-enabled TV services and generate new and expanded revenue streams for broadcasters and operators.
Rosums technology opens a new era in location-based applications and services, says Siano CEO, Alon Ironi. Our cooperation with Rosum will enable every user of a handheld device to not only watch TV everywhere, but also benefit from an abundance of location-based services everywhere, even where the line-of-sight to the global positioning satellites is blocked.
