Probably shared here before. Much interest for me as I've been working on projects that tracks people by their wifi signal and also being able to see number of people in a room and where they are positioned.(through walls)

Do yourself a favour and turn off WiFi scanning in your improve location accuracy setting. And wifi when not in use (phone)

Apologies if already posted but another article about using wifi signal to see through walls. And our friends at Carnegie Mellon University are working on the technology.
The technology works by sending a low-powered WiFi signal through a wall, which reverberates around the room. It detects all the objects in the room, cancels out the static objects, and when the signal bounces back, uses the reflection of moving objects to generate a radar-like image. It can work through standard drywall, wooden fences, and even concrete walls, though the range and accuracy depend on the type of wall.
The Carnegie Mellon researchers believe that WiFi signals “can serve as a ubiquitous substitute” for normal RGB cameras.
A breakthrough system can see through walls by using Wi-Fi routers
The method detects all the objects in the room and cancels out the static objects.
