Scientists in Germany have demonstrated a startling new form of surveillance: identifying people using nothing more than ordinary WiFi signals. By analyzing how radio waves bounce around a room, researchers can effectively “see” and recognize individuals — even if they are not carrying a device and even if their phone is turned off.
Damn. Put a faraday cage around the router and plug in your own router to a LAN port.
Wrap it in aluminum foil.
Whilst this sounds a lot like a foil hat joke, that’s literally the easiest way to wrap something in a conductive material cage (i.e. a faraday cage).
If you don’t want it to look ridiculous, put it inside a box whose inside has been lined with aluminum foil.
Mind you, personally I too would just cancel that shit, but the option is there to carry on using it whilst blocking its radio emissions.
