ABSTRACT
The expressions for path loss discussed in Chapter 5 will yield values for average path loss. Actually, real values of path loss will be larger or smaller than the average value, depending on the mix of buildings on a particular path between the base station antenna and the mobile. If the design of a cell phone system only allows for the average value of path loss, the expected probability of a successful call would be only 50%. This is unsatisfactory, and one must learn how to compensate for the stochastic component of path loss. We begin by reviewing some fundamental concepts in statistical analysis.
