Here is the most comprehensive reference available on GSM applications and services that?s intended to build on - not replace - the basic technical information in the authors? original bestseller, An Introduction to GSM. The book provides a close-up look at this hot technology, offers in-depth discussions of the features and services available through GSM, and includes new and more in-depth coverage of applications and implementations of the GSM standard. It also explains how GSM has succeeded in becoming the major digital wireless standard - and addresses both past and future standardization, regulation, and development issues. The book uses non-technical language and unique technical implementation and performance figures to: show how intelligent mobile networks function - and what benefits they provide to users, compare PCS to GSM and other competing digital radio systems, examine the technology and techniques used in PCS handsets. The book is an up-to-date, single-source guide for engineers, technical managers, and consultants at communications manufacturing and network operating sites who need a technical background on services, features, and implementation - or information on the adoption of GSM and competitive technologies. It is also a valuable source for marketing and sales professionals, university lecturers, and post-graduate students who need to acquire background knowledge of GSM technology or services.
