A researcher duo at the University of California, Santa Barbara has developed a new system by means of which a pair of drones can peek into a closed building by using just Wi-Fi signals. The approach holds promise for indoor mapping and emergency situations when it’s not possible to enter a closed structure to know what’s happening inside.

The two drones work in tandem, with one of them blasting the Wi-Fi signals through the walls and the other picking them up to map the interiors, notes The Tech Portal.

The system, built using off-the-shelf devices, doesn’t require any prior measurement of the site nor does the objects inside must be moving for 3D modeling, writes Tech Crunch.
