Wi-Fi could soon have a very detailed geofence, if MIT researchers have their way. They’ve introduced a new project named ‘Chronos’ that helps Wi-Fi signals locate you within “tens of centimeters.” The team managed this by monitoring several Wi-Fi bands, then cobbling the data together to find out how long a signal takes to find the end user. In knowing the time and distance it takes for a Wi-Fi signal to travel, MIT can create advanced geofencing. In an experiment, MIT tracked users in a two bedroom apartment, and found Chronos could correctly identify the location of those users 94…
