Global System For Mobile(GSM)

Global system for mobile(GSM) is a second generation cellular system standard that was developed to solve the fragmentation problems of the first cellular systems in Europe's is the world's first cellular system to specify the digital modulation and network level architecture and services. Before GSM, European countries used different cellular standards throughout the continent, and it was not possible for customer to use a single subscriber unit throughout Europe. GSM's success has exceede ....etc

Introduction:
Background and Requirements:
At the beginning of the 1980s it was realized that the European countries were using many different, incompatible mobile phone systems. At the same time, the needs for telecommunication services were remarkably increased. Due to this, CEPT (Conf rence European Posts Telecommunications) founded a group to specify a common mobile system for Western Europe. This group was named Groupe Sp ciale Mobile and the system name GSM arose. This abbreviation has since been i ....etc
