The book describes how interference can be managed so that radio systems co-exist, without harmful mutual effects, within a finite amount of spectrum. This is timely in view of the increasing proliferation of wireless systems. It covers both the processes, such as regional or international coordination, as well as the engineering principles. Written by an author with extensive experience in the industry, it describes in detail the main methodologies for calculating or computing the interference between radio systems of the same type, and also between radio systems of different types

The RADC program, is a continuing study of electromagnetic interference pheonomena with the aim of developing radio frequency interference prediction and analysis methods. The work to be described was performed by Jansky and Bailey under Contract AF-30(602)-1934 and is presently being extended under Contract AF-30(602)-2665. The development of prediction and analysis methods is logically broken into two major fields of inquiry. First, what are the individual input factors which must be considered, what is their form and how may they be predicted? Second, once these input functions have been defined, how may they be combined to yield meaningful predictions of the interference likely to occur in any given stituation? This presentation represents Jansky and Bailey's fourth presentation in the area of interference prediction and analysis at the various RADC Contractor's Conferences held over the past few years. The first two presentations emphasized the input functions, their form and methods for evaluating them by prediction. Last year, the emphasis was upon the methodology of the prediction process itself.

Since interference is the main performance-limiting factor in most wireless networks, it is crucial to characterize the interference statistics. The main two determinants of the interference are the network geometry (spatial distribution of concurrently transmitting nodes) and the path loss law (signal attenuation with distance). For certain classes of node distributions, most notably Poisson point processes, and attenuation laws, closed-form results are available, for both the interference itself as well as the signal-to-interference ratios, which determine the network performance. This monograph presents an overview of these results and gives an introduction to the analytical techniques used in their derivation. The node distribution models range from lattices to homogeneous and clustered Poisson models to general motion-invariant ones. The analysis of the more general models requires the use of Palm theory, in particular conditional probability generating functionals, which are briefly introduced in the appendix.
