WiFi surveillance and wireless person identification explained with real research and chilling accuracy stats. How ordinary routers enable device‑free WiFi tracking technology, radio wave sensing, and indoor surveillance without your phone. Understand how WiFi spying works, what it means for privacy and surveillance tech, and what you can realistically do about it. What You'll Learn: * How modern wifi surveillance systems turn everyday 802.11ac routers into powerful wireless person identification tools. * The core physics of radio wave sensing and how WiFi motion detection can uniquely “fingerprint” your body and walking style. * The real capabilities and limits of current wifi tracking technology, including accuracy rates, training times, and indoor range. * Why device free tracking works even when your phone is off—and how indoor surveillance technology exploits normal WiFi traffic. * Concrete privacy concerns technology experts are raising, from home spying to workplace monitoring and state surveillance. * What existing laws do (and don’t) cover when it comes to WiFi spying and passive radio-based identification of people. * Potential countermeasures and practical steps you can take to reduce your exposure to WiFi-based surveillance at home and in public. * How this research fits into the broader evolution of privacy and surveillance tech, and what might come next in radio-based sensing.
