ABSTRACT

Propagation in wireless communication can be defined as the means the radio waves travel through free space or the medium, which in this case is represented by the air, from a source to a destination. Depending on the way these waves travel their signal strength might be affected. As radio signals propagate through the environment they may penetrate through obstacles that appear in their path. However, due to the conductive nature of the various obstacles' materials, the radio signals might be more or less weakened or even completely blocked. The radio signals can be reflected by buildings or diffracted around sharp edges which weakness the strength of the signal. This chapter aims to introduce the reader to the basic concepts in signal propagation as well as different radio propagation models. Additionally, practical use-case scenarios are introduced to study the impact of various radio propagation models using Altair WinProp software.
