Can AI use WiFi to visualise people in a room?
Can AI use WiFi to visualise people in a room?
Saw it on TikTok that when a camera and WiFi are active, and then the camera removed, AI can visualise people in the room
Steve Mould did a great video explaining this: https://youtu.be/QtMTvsi-4Hw
2Sure. WiFi is just using radio waves, and if the software is advanced enough, you could potentially use wifi signals as a form of radar to map things. Not sure how great the resolution could potentially be though.
1A thing to keep in mind is that wifi signals pass through human bodies prettty well, which reduces its ability to detect them clearly.

This has been a “thing” for a while now. Here’s a Hackaday article on it from 2018:

0We really just sleepwalking into a Cyberpunk dystopia huh?
1You better start believing in cyberpunk dystopias, matey.
You're living in one.

To be clear, this is using the same frequencies WiFi uses, but customized hardware and software to accomplish the task. Those frequency bands can of course penetrate walls. It's why we picked them for network connectivity.
It's a long jump from yet another method to detect things using EM radiation to plugging an AI into your WiFi router to spy on people.
