The Fundamentals of Radio Wave Propagation
How do radio waves get from one location to another? Why does a signal at generated at Point A, which is several thousand miles away, reach Point B without a complicated myriad of connecting wires? The answer, in three words, is radio wave propagation. Radio wave propagation theory is of particular importance to wireless communications, for, without a preliminary understanding of the physical nature of wave propagation it is impossible to ensure that communications can be established at all.
