Samsung working on atmospheric broadcasting

Researchers and employees of Korean company Samsung are devising a method to use the ionosphere as a medium for 'long distance communication' without the need for expensive satellites.

The ionosphere already plays a role in communications as a 'radio reflector' for shortwave signals.

But by launching UHF signals behind a 1GHz carrier signal, scientists hope to alter the behaviour of the ionosphere to create an alternating current, which can then be modulated at a particular frequency in order to create an antenna of global proportions.
