Isn't it only 20000 km to the other side of the world?

  This is to a satellite, so the distance is correct and has line of sight. The main enabler is a hack to the ESP firmware (done elsewhere) which changes the frequency from the WiFi frequency. [And it's morse code, which simplifies things a lot]
