Unlike wireline communication channels whose propagation conditions are static, mobile radio channels present random propagation conditions. This is due to the fact that the channel is mobile in nature and the path between the transmitter and the receiver is not fixed. It can range from line-of-sight propagation in free space, to being severely blocked by buildings, terrain, foliage, and other obstacles. Modeling the effects of path loss is an important part of wireless communication system design. This paper will present the theory of mobile radio propagation, measurement techniques, modeling and simulation methods, and how these factors effect network design. Simulation of reflection, diffraction, and scattering is the main focus, however other models and aspects of radio channel propagation will be explored as time permits.
