The most comprehensive reference available on GSM applications and services, this new title is intended to build on the basic technical information in the authors' original bestseller, An Introduction to GSM (Artech House, 1995). 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.
