The ionosphere as a giant wireless antenna

First there was HAARP messing with the ionosphere - now it is an electronics company wanting to provide blanket wi-fi coverage!

'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 antenna. A patent application filed by the company reveals plans to direct higher frequencies radio signals, at about 1 gigahertz, at the ionosphere, to alter its behaviour.'
