Answer:Thermosphere

Explanation:

In the Thermosphere, ultraviolet radiation causes photodissociation of gases. The temperature increases with hieght and gases are present as dissociated ions. This is a very high temperature region, it is here that radio waves are transmitted. The electrically charge particles multiply refract radio waves causing them to be received across the horizon.
