Rosum's Alloy chip promises 'precise' location using TV signals
Though plenty of firms (including some big ones) have been trying to commercialize consumer-facing indoor positioning technologies for years, none have succeeded on a wide scale -- which certainly seems to leave the door wide open for a system that actually works to be wildly successful, doesn't it? Rosum has been toying with the idea of using plain old TV signals to accurately locate people and objects within GPS-hating structures for years, and with today's launch of its so-called Alloy system with partner Siano, the company could be closer to wide-scale deployment. Basically, Alloy combines AGPS (for maximum precision outdoors and in marginal areas) with support for a variety of types of TV signals to enhance coverage and provide <150 meter accuracy even in the deepest, darkest, dankest corners of your home where traditional GPS would never dream of going. What's more, Rosum touts that TV positioning is several orders of magnitude more power-efficient than AGPS, music to the ears of anyone who's struggling to get a full day's battery out of their phone. They're sampling chipsets beginning this month, but don't expect it in handsets right away -- Rosum's primary target appears to be femtocell makers. The devices traditionally require GPS reception, requiring unsightly remote GPS antennas if you're not interested in balancing the cell on a window sill, so a technology like this should let you properly bury that network extender behind a bookshelf where it belongs.
