Tired of crossing your fingers while trying to locate a WiFi signal? What if, instead, the WiFi could locate us?

The smart cats at MIT are on it.

In a new paper, a research team led by professor Dina Katabi of MIT's Computer Science and Artificial Intelligence Lab (CSAIL) presents a system that enables a single WiFi access point to locate users to within tens of centimeters, without any external sensors. The group demonstrated the system in an apartment and a cafe, while also showing off a drone that maintains a safe distance from its user with a margin of error of about four centimeters.

According to researchers the technology could mean safer drones, smarter homes and password-free WiFi...
