Radio propagation categories. There are a number of categories into which different types of radio propagation can be placed. These relate to the effects of the media through which the signals propagate. 1  Free space propagation: Here the radio signals travel in free space, or away from other objects which influence the way in which they travel. 2  It is only the distance from the source which affects the way in which the field strength reduces.
Radio waves are distinguished from other kinds of electromagnetic waves by their wavelength, a relatively long wavelength in the electromagnetic spectrum.Propagation is a term that describes the travel of electromagnetic waves, there being three main modes of propagation.
