GLOBAL SYSTEM
FOR
MOBILE COMMUNICATION

Definition:
Global system for mobile communication (GSM) is a globally accepted
standard for digital cellular communication. GSM is the name of a
standardization group established in 1982 to create a common European
mobile telephone standard that would formulate specifications for a
pan-European mobile cellular radio system operating at 900 MHz. It is
estimated that many countries outside of Europe will join the GSM
partnership.

Global satellite system communication



INTRODUCTION

To make a satellite phone call today from a location that does not offer terrestrial wireline or wireless coverage requires the use of a large, costly terminal, and entails very high per minute charges. Further, the quality of service is relatively poor because of annoying echoes, large transmission delays, overtalk associated with satellite communications using geostationary satellites. The next generation of satellite commun ....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

Abstract
This report presents the design, implementation, and testing of a dual-band cell-phone jammer. This jammer works at GSM 900 and GSM 1800 simultaneously and thus jams the three well-known carriers in Jordan (Zain, Orange, and Umniah). This project went through two phases:
Phase one: studying the GSM-system to find the best jamming technique, establishing the system design and selecting suitable component ....etc

Enhanced Data rates for GSM Evolution (EDGE)

ABSTRACT
ENHANCED DATA RATES FOR GSM EVOLUTION
Enhanced Data rates for GSM Evolution (EDGE) (also known as Enhanced GPRS (EGPRS), or IMT Single Carrier (IMT-SC)) is a backward-compatible digital mobile phone technology that allows improved data transmission rates, as an extension on top of standard GSM. EDGE is considered a 3G radio technology and is part of ITU's 3G definition. EDGE was deployed on GSM networks beginning in 2003 initially by Cingular (now AT&T) in the United States.

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

Global politics names both the discipline that studies the political and economical patterns of the world and the field that is being studied. At the centre of that field are the different processes of political globalization in relation to questions of social power.

The discipline studies the relationships between cities, nation-states, shell-states, multinational corporations, non-governmental organizations and international organizations. Current areas of discussion include national and ethnic conflict regulation, democracy and the polit ....etc
