Microwaves are a form of electromagnetic radiation with wavelengths ranging from one meter to one millimeter; with frequencies between 300 MHz (100 cm) and 300 GHz (0.1 cm).[1][2][3][4][5] Different sources define different frequency ranges as microwaves.
That means means that microwave stations use line-of-sight transmission and signals travel in straight line. The two types of microwave transmission are terrestrial and satellite:
Terrestrial microwave transmissions are sent between two microwave stations on the earth (earth station).
