📡 HOW DOES IT WORK?
WiFi signals bounce off walls, objects, and people. By analyzing tiny disturbances in those signals(e.g., through the Doppler effect or signal distortion), AI algorithms can detect:
- If someone is moving
- Where they are in the house
- How fast and in what direction they’re moving
- In some cases, even heart rate and breathing

🧠 SCIENTIFIC DEVELOPMENTS
Research from institutions like MIT and Carnegie Mellon shows that WiFi routers, combined with machine learning, can:
- Distinguish between individuals
- Detect activities such as walking, sitting, or falling
- Monitor breathing and heart rate remotely (using millimeter-wave radar)
📚 Study: “DensePose from WiFi” (2023) – Researchers managed to reconstruct a skeletal human figure using WiFi, similar to how a camera with AI detects body posture.

🔒 PRIVACY RISKS
This raises real concerns:
- You don’t even need to carry a device
- It can happen without your consent if someone has access to the network
- Smart devices (like smart speakers) could theoretically be used for this as well
⸻
🛡️ WHAT CAN YOU DO?
- Turn off WiFi when not in use
- Use routers without advanced tracking or radar features
- Prefer ethernet cables where possible
- Monitor and restrict unknown devices connected to your network
- But to be fair you can’t do anything about it, it’s scary what they can do
