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
