Using two ESP32-S3 modules you can get ~6000 packets per second with CSI data. I'm using this as a cheap replacement for specialty high-G gyroscope modules, but it could see use for this type of motion detection as well.

Are you using two separate S3s as a dedicated Transmitter/Receiver pair, or are both transmitting data simultaneously?

Transmitter/Reciever pair.
