Another take on this paper would read, “Engineeers have created a way to weaponize Wi-Fi signals for invisible and invasive surveillance”.

This turns consumer level tech into a militant authoritarian’s dream. Have they also developed ways to identify when this technology is being used surreptitiously?

This method appears to just measure the Tx and Rx paths on an off-the-shelf modem, so you'd have to physically check the router, or I'm sure this could be handled in firmware. They're measuring phase and amplitude differences from unmodified traffic on 2.4GHz so you can't detect it as an outsider.
