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 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

ABSTRACT

With the Information age in full and rapid development, users are becoming accustomed to having immediate access to information. Users demand more capabilities from every kind of electronic devices, more processing power, more features and better connectivity. Users are also realizing the benefits of collaborating with others in their communities to help expand the body of knowledge. One user that understands the benefits of information sharing is the United States Department of Defense. The DoD s Networks-centric enterprise ....etc

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

Abstract
LEO is Low Earth Orbit satellite.It circulates on a lower orbit in a shorter period . Additionally LEO systems try to ensure a high elevation for every spot of the earth to provide a highquality communication page link . The networks will play an important role in the evolving information infrastructure . It provides communication with shorter endto- end delays and e_ciency frequency usages . Some problems need to be solved before LEO satellite system can be successfully deployed . One of these problems is handover management . Even ....etc
