There is none. A phone indoors gave up a person&rsquo;s breathing to a receiver three meters outside the wall.</p> <p>The radio waves coming out of your router do not stop at the wall. They go through it, bounce off the floor, the cupboard and the person walking to the kitchen, and arrive at your phone along dozens of paths at slightly different times. Something in the room moves, those paths change, and the receiving device measures that change constantly, because it needs to know which speed and which antenna to use.</p>
