DEVELOPMENT OF GSM JAMMERThe widespread usage of Mobile Stations (MS) in Improvised Explosive Devices (IEDs)is becoming a common mean of detonated bomb attacks by terrorists, to createinstability and havoc. To prevent such activities from occurring GSM jammers haveacquired great importance.The principal goal of our project is to ensure the provision of compact, cost effectivemobile GSM jamming devices that are affordable by the general public. These devicesare meant to be handheld and used by the ground forces in the field area or by ordinarypeople while moving from place to place.Devices operating in the mobile GSM range or being operated by mobile devices can berendered ineffective if the communication within the specific region, in which theexplosive device is placed, is hindered. The project focuses on the implementation ofDenial Of service (DoS) Jamming technique whereby the downlink bands of the GSM900 and GSM 1800 are targeted and jammed respectively because of which the mobilephones are denied of service. A jamming signal, being a noise signal, distorts thecommunication signal thus denying the serviceA prototype GSM jammer is being designed and built which is capable of jamming boththe GSM 900 and GSM 1800 bands, currently being used in Pakistan. This prototypeconsists of three parts namely a power supply, a sweep generator and an RF section.Syndicate Members: Muaaz Ahmed BhattiIbrahim Hanif SahafHamza Mehboob ChaudhryHassan IrshadSupervisor:Asst Prof Raja Iqbal28
