Hi everybody! I have heard that this new kind of tracking will use TV signals to find out where exactly are people inside the building. Is it even possible at all?

Indoor tracking is a popular tech trend nowadays. There are many different companies, both small and big ones, are trying to become the first one in this type of location tracking for many years. One of those companies that is called Rosum made some progress in this field, but this progress is quite unusual. They are planning to use mobile TV signals to enhance tracking indoors.
Rosum developed an absolutely new system that they have called ALLOY. Their partner is a company called Siano that specializes on quality mobile TV no matter where you are - indoors or outdoors. So those two companies have combined their efforts to make this new technology and develop new way of tracking people and other objects inside different buildings.
Their ALLOY indoor tracking technology works in this way: the A-GPS signal that is used for precise outdoor tracking will do the first part of the location finding job, and the mobile TV signals will be used for further location alignment inside the building where GPS tracking is almost helpless. So in that way ALLOY will know exact spot where you are in the building.
Rosum will manufacture first chips with ALLOY technology inside this month, but they will be femtocell-oriented, so do not expect this technology on handsets soon. Nevertheless, tracking technology is constantly developed so if this tracking will succeed then it may appear on smartphones in the next year maybe. But jamming technology is also developed at the same time. As long as there is no point in jamming all TV signals in your house, you can just block Rosum ALLOY indoor tracking signal by jamming its A-GPS part and leaving mobile TV signals to work like they should, i.e. as an ordinary mobile TV signals.
