Chronos: MIT tracking system behind the walls

MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) has created a new system called . The new technology can pinpoint the location of a person or object within a room using only Wi-Fi signals.chronos

The Chronos system works without the aid of secondary sensors, using a technology called time-of-flight calculation, which measures the time it takes να ταξιδέψουν από το σημείο πρόσβασης του WiFi στη of the user.

According to MIT researchers, this new system is 20 times more accurate than the current WiFi tracking systems. Researchers report that Chronos showed a success rate of 94%, detecting a person in exactly where it is in a room, and a 97% if the customer of a store was in or out of the store.

Researchers report that coffee shops and they can benefit from a technology like Chronos, because it will allow them to use WiFi connections that do not require passwords and will only be directed to their customers, and not to those who wander aimlessly around the premises and within the range of the Wi-Fi .

Another use of Chronos could be if it was placed on unmanned aircraft (drones) to allow its pilots to scan and explore indoors by discovering faces from above.

Chronos needs only one access point. Previous WiFi tracking systems required at least four connections, which, in various combinations, performed triangular work to locate a person's room in a room.
