Can I see through the walls and see the neighbours walking?
Apparently you can! Jeija is a YouTuber from Germany and in this video he shows how the Wifi signal is behaving indoors, with reflections and behind the walls. He uses a ESP32 Array antenna and overlays the visualized Wifi signal over the real picture.
Later in the video he takes you a level deeper into the behavior and propagation and the setup of the measurement. All with all an interesting experiment for those interesting in Electromagnetic propagation.
