The General Packet Radio System (GPRS) is a new service that provides actual packet radio access for mobile Global System for Mobile Communications (GSM) and Time-Division Multiple Access (TDMA) users. The main benefits of GPRS are that it reserves radio resources only when there is data to send and it reduces reliance on traditional circuit-switched network elements. The increased functionality of GPRS will decrease the incremental cost to provide data services, an occurrence that will, in turn, increase the penetration of data s ....etc

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.Throughout the evolution of cellular telecommunications, various systems have been developed without the benefit of standardized s ....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 d ....etc

The motivations for security in cellular telecommunications systems are to secure conversations and signaling data from interception as well as to prevent cellular telephone fraud. With the older analog-based cellular telephone systems such as the Advanced Mobile Phone System (AMPS) and the Total Access Communication System (TACS), it is a relatively simple matter for the radio hobbyist to intercept cellular telephone conversations with a police scanner. A well-publicized case involved a potentially embarrassing cellular telephone conversation ....etc

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 ....etc
