This text surveys the principle tools used in the planning of micro/pico cellular systems for personal communication networks. It offers readers an accurate analysis of radio propagation in cellular networks using the proven techniques described in this book, and explores how to use specific computer codes to perform a reliable analysis of the major apsects of micro/pico cellular design including propagation, fading estimation, mutual interference, cell geometry, teletraffic, and channel allocation. The text also explores how to improve the design of microcellular network systems by combining propagation models with topographical/morphological databases and ray-tracing acceleration techniques. The authors explain physical optic, geometric optic and the uniform theory of diffraction for the analysis of propagation in complex urban or indoor scenarios. Also included are computer models and applications to PCS planning, a tutorial presentation of the application of UTD to wireless problems and ray-tracing algorithms.
