I’ve been seeing research on this for a few years now, crazy it’s come this far. You can track the movement of people in a home pretty accurately using WiFi like a radar
i proof-read a dissertation on that very subject 10 years ago. it was using Bluetooth Low-Energy but the principle was the same. works through walls as well.
Not at all in this case since it works by watching how the signals bounce around in a space. I believe any large object could be tracked by this. You could then use the phone in their pocket to identify the large object

Bluetooth is often used when tracking movement and wait times through queue lines in airports.
