 Thoroughly revised and updated, the scond edition offers a fundamental and comprehensive treatment of how mobile systems operate in a variety of scenarios. This unrivalled approach concentrates on the properties of the radio channel, a vital and central feature that place fundamental limitations on the performance of radio systems. * Features two new chapters: 'Multipath Mitigation Techniques' and 'Radio System Planning' * Surveys various alternative methods of predicitng the mean signal strength and its variability, and discusses their applications * Introduces ray-tracing methods in connection with indoor propogation * Discusses multipath and its effects on narrowband and wideband systems * Describes channel sounders and reviews methods of hardware and software simulation * Examines man-made noise and interference, and discusses the resulting performance degradation By equipping the reader with a thorough understanding of the physical processes that underlie the propogation of radio waves, this systematic approach will prove to be an authoritative and attractive text for researchers, systems designers, university academics and postgraduate students.
