Radio Propagation for Modern Wireless Systems

Chapter 8Site-Specific Propagation Prediction

In Chapters 6 and 7, the building environment was described in terms of statistical parameters, such as the average row spacing and the building height distribution, as a basis for making propagation predictions. As an alternative approach, in this chapter we discuss site-specific predictions that make use of a database of the actual shapes of buildings in the region under study. In this work we classify such predictions into three categories: two for outdoor propagation around and over buildings and a third dealing with propagation between subscriber and access point located inside a building or tunnel. One category of outdoor predictions applies to low antennas in a tall-building environment, where ...
