Scientists develop an approach which uses WiFi signals to trace still objects.
WiFi can read through the walls. A team of researchers has developed a new method that can replicate the image of a still object from behind a wall using WiFi. Does this mean we can spy on our neighbors next door? Quite unlikely.
Sensing moving things using WiFi signals has shown promise; there’s a challenge in doing the same for non-moving objects because they lack motion, enabling calls to track them, explain the researchers in the press release.
