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

General Safety

It is important to follow any special regulations regarding the use of radio equipment due in particular to the possibility of
radio frequency, RF, interference. Please follow the safety advice given below carefully.
Switch OFF your GSM Modem when in an aircraft. The use of cellular telephones in an aircraft may endanger the
operation of the aircraft, disrupt the cellular network and is illegal. Failure to observe t ....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

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
