Abstract:
Mobilejammer is used to prevent mobile phones from receiving or transmitting signal switch the base station.
This research presents the design of Jammer Cell-Phone. This research have implemented the First section of the device due limitations of obtaining the rest of the required components but the design and the calculations have been measured to achieve the full design. The design if manufactured correctly shall be capable of jamming the GSM 900 and GSM 1800 simultaneously and therefore jams the three well-known carriers in Sudan (MTN (Ariba), Zain, and Sudani).
This research went through two phases:
Phase one: Studying Jammers devices/circuits and GSM networks.
Phase two: studying the Radio frequency methodology and acknowledge its participation in our project and design. Then collecting the parts and studying their behavior in real-time Systems.
Only implemented design of jammer cellphone.
Keywords: Jammer, GSM
