Using Wi-Fi to Get 3D Images of Surrounding Location

Posted on by

Interesting research: The radio signals emitted by a commercial Wi-Fi router can act as a kind of radar, providing images of the transmitter’s environment, according to new experiments. Two researchers in Germany borrowed techniques from the field of holography to demonstrate Wi-Fi imaging. They found that the technique could potentially allow users to peer through walls and could provide images… Continue reading Using Wi-Fi to Get 3D Images of Surrounding Location→
