Propagation Modelling

Ever since Personal Communication Systems appeared there is an increasing demand for effective tools to model radiowave propagation. The purpose of this chapter is to give an overview of existing models, with particular emphasis placed on deterministic (theoretical), site-specific approaches. Other techniques will be briefly mentioned as well, but with less attention, as the way in which they describe the radio channel does not always provide sufficient information for the planning of modern wideband wireless systems. To better understand the idea behind these models, some place will be devoted to the analysis of physical phenomena which assist the propagation of the electromagnetic (EM) waves and their interactions with the environment.
