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.
In general talk, people mean Wifi access points when they talk about routers though. That’s what matters, not what it “really” means.
There are many other types of routers, a large portion of them without any wireless. You only know household shiz. ALL routers have been banned. This is a huge problem industrywide.
