Seeing Through Walls Using Radio Waves

If I told you that you could see through walls, would you believe me? Turns out radio frequency sensing signals that we use to communicate can now be used to map the world in immaculate detail. We can use it to detect change, measure heartbeats, and identify individuals. It's extremely powerful, like that scene from Batman where he uses every single cell phone device as a sonar to find the Joker. That's becoming more and more like reality. A lot of the discourse online seems to get into hyperbole but there is a foundation of real research, which is what we'll get to in the short and the full video from the lineage of DARPA projects to the patents underpinning them, as well as the latest cutting-edge research that's making consumer and enterprise applications increasingly science fiction today
