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.
The reason the FCC is only allowing the sale of state approved routers in the US?
Wifi tracking uses measurements of the interference caused when objects pass between connected devices and a router. For your neighbors to track your movements their router would have to be connected to a device in your house, or maybe in the other neighbor’s house on the far side of your house, so when you walk around it interferes with that signal.
my devices don’t, but unless I misunderstood it it does not matter whether you are connected to the neighbor’s router
