WebGround-wave transmission is used mainly for local communications. The sky wave is an electromagnetic wave propagated at such an angle that it travels up through the atmosphere, strikes its upper layer (the ionosphere), and refracts back toward the earth. Sky-wave transmission is used in long-distance communications.

WebSky Wave Propagation enables more efficient communication over larger distances and higher frequencies. Sky wave Propagation happens through utilisation of ionised layers of the Ionosphere due to the interaction of sun rays. It is imperative to understand the structure of the Ionosphere to properly understand the Sky wave Propagation.
