Because you use light to communicate in sign language, and light is just an electromagnetic wave like radio but on another frequency. You just need to be in line of sight

Really, radio communication is about creating and transmitting those radio waves. Sign language relies on reflected light waves so it’s actually a form of RADAR 😀
