GSM, GPRS and EDGE Performance - Second Edition provides a complete overview of the entire GSM system. GSM (Global System for Mobile Communications) is the digital transmission technique widely adopted in Europe and supported in North America. It features comprehensive descriptions of GSM’s main evolutionary milestones - GPRS, (General Packet Radio Services) is a packet-based wireless communication service that promises data rates from 56 up to 114 Kbps and continuous connection to the Internet for mobile phone and computer users. AMR and EDGE (Enhanced Data GSM Environment), and such developments have now positioned GERAN (GSM/EDGE Radio Access Network) as a full 3G radio standard. The radio network performance and capabilities of GSM, GPRS, AMR and EDGE solutions are studied in-depth by using revealing simulations and field trials. Cellular operators must now roll out new 3G technologies capable of delivering wireless Internet based multimedia services in a competitive and cost-effective way and this volume, divided into three parts, helps to explain how: 1. Provides an introduction to the complete evolution of GSM towards a radio access network that efficiently supports UMTS services (GERAN). 2. Features a comprehensive study of system performance with simulations and field trials. Covers all the major features such as basic GSM, GPRS, EDGE and AMR and the full capability of the GERAN radio interface for 3G service support is envisaged. 3. Discusses different 3G radio technologies and the position of GERAN within such technologies. Featuring fully revised and updated chapters throughout, the second edition contains 90 pages of new material and features the following new sections, enabling this reference to remain as a leading text in the area: Expanded material on GPRS Includes IMS architecture (Rel’5) and GERAN (Rel’6) features Presents field trial results for AMR and narrowband Provides EGPRS deployment guidelines Features a new chapter on Service Performance An invaluable reference for Engineering Professionals, Research and Development Engineers, Business Development Managers, Technical Managers and Technical Specialists working for cellular operators
The Global System for Mobile Communication (GSM) is undoubtedly the most successful second generation digital mobile radio system. One of the key factors for this exceptional performance is the constant evolution of the GSM systems and its derivatives DCS-1800 and PCS-1900. The objective of the book is to address new concepts in the GSM system, dealing with both standardised features as well as theoretically and technologically feasible improvements, which contribute to evolutionary changes in general. Dynamic evolution of GSM presents a platform for the Universal Mobile Telecommunication System (UMTS) introduction and major trends in UMTS development will be addressed in this book, in particular progress towards new radio interface. The book is the collection of individual contributions from a number of authors. The intention of the editors was to gather the most prominent specialist in the GSM area. Ongoing efforts in GSM standardisation are focused on Phase 2+ with items planned to be added gradually on demand. Being mostly independent of each other, each of them could be introduced with little impact on the rest of the system. Speech remains the prime service of cellular systems with ongoing work on spectral efficiency taking into account the trade-off between cost of the system and transmission quality. Most notable result from novel speech service implementations is the introduction of new Enhanced Full Rate (EFR) speech coder. International railway organisation (Union Internationale des Chemins de Fer - UIC) has influenced the development of Advanced Speech Call Items (ASCI).

This book explains the evolutions of architecture for mobiles and summarizes the different technologies: – 2G: the GSM (Global System for Mobile) network, the GPRS (General Packet Radio Service) network and the EDGE (Enhanced Data for Global Evolution) evolution; – 3G: the UMTS (Universal Mobile Telecommunications System) network and the HSPA (High Speed Packet Access) evolutions: - HSDPA (High Speed Downlink Packet Access), - HSUPA (High Speed Uplink Packet Access), - HSPA+; – 4G: the EPS (Evolved Packet System) network. The telephone service and data transmission are the two main services provided by these networks. The evolutions are fundamentally dictated by the increase in the rate of data transmission across the radio interface between the network and mobiles. This book is intended as a readily understandable support to help students and professionals wishing to quickly acquire the main concepts of networks for mobiles understand the technologies deployed.
