Another communication patent find from wonderful Barry Fox for NewScientist.
"The layer of the atmosphere known as the ionosphere, at an altitude of 50 kilometres, is already used as a radio reflector, bouncing low frequency radio signals from one side of the world to the other.
Researchers at Samsung in Korea are now working on a way to turn the ionosphere into an antennaand have filed a patent.
Samsung sees the system as a cheap way to broadcast signals, or communicate over long distances, without needing to launch expensive satellites."
