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.
These waves carry with them information from the layers they pass through â including the mantle and the core.
