This topical new book builds upon an earlier IEE text Personal mobile radio systems@ by the same editor@ which set out the fundamental issues in a discipline that appeared to have global expansion potential. That potential has now become a reality@ and something more than a new edition of the previous book was needed to bring it up to date. This book is completely new@ drawing on the experience and the many intensive studies that have been concentrated in this field in the past five years. The book gives a clear and detailed insight into the fundamental problems and solutions found in modern personal communications: service requirements@ coverage problems@ multipath interference@ cellular architectures and signalling@ network management@ data and supplementary services@ satellite services. In particular it describes the approach of the GSM methodology@ as one of the most intensively developed standards@ to some of these problems@ although the same principles also apply to DCS 1800 and other technologies.
