Gsm

Global System for Mobile (GSM) has captured a large share of the global cellular market. This book explains, technologies used, Operation of GSM systems and GSM _cellular technical specification. It describes the Base Station Subsystem Engineering aspects of GSM as a whole, covering GSM evolution,GSM network architecture, Radio Interface and resources,Um radio interface and signal processing, The Abis, Data Transmission and securities, Radio Cellular Engineering fundamentals, Network Operations,GPRS overview and Operations Case Studies. Explained are the physical and logical radio channel structures of the GSM system along with the basic frame and slot structures. Described are the fundamental capabilities and operation of the GSM radio channel including channel coding, speech coding, RF power control, Handover types and algorithms and signaling at BSS. You will discover that the GSM system essentially separates circuit switched (primarily voice) and packet switched (primarily data) services. Described are key functional sections of a GSM network and how they communicate with each other. You will learn how and why GSM is evolving into 3rd generation broadband systems including GPRS, EDGE, and UMTS.
