Wi Fi networks can now detect human presence and movement through walls by analyzing subtle signal changes, turning wireless waves into a powerful sensing tool without cameras or visual data. This works using Wi Fi Channel State Information, which tracks tiny variations in phase, amplitude, and timing as signals bounce off the human body, while multiple devices send and receive data that machine learning models learn to interpret accurately in real time. It is still experimental, but it could reshape search and rescue, elder care, and smart buildings by enabling privacy friendly security systems that sense presence, breathing, and movement without relying on cameras at all. #AI #Tech #Future_Tech #Innovation
