Answer 1

It is done a few different ways. A radio repeater is used, you could think of it as playing whisper down the lane with a device that listens and repeats what it hears. The other main method is to bounce it off the ionosphere, this is kind of like trying to bounce a ball around a corner by using the wall opposite the corner.
