Abstract
Due to technological advancement in the mobile phone industry, mobile phones have become a very vital communication device today with number of end user applications embedded. For instance; Games, online videos, e-commerce, social media like Facebook, whatsapp, twitter, to mention but a few. This has resulted to the use of mobile phones everywhere which become disruptive while praying, studying, in meeting, in court room, driving, examination rooms, etc.
The main purpose of this project was to design and build a system that can block the use of mobile phone by transmitting radio waves of the same frequencies as that of the mobile phone causing interference between mobile phone and the Base Transceiver Station, hence the mobile phone displays "NO NETWORK" on the screen so that it can be installed in places where the use of mobile phone is not required. Although different cellular systems process signals differently, all cell-phone networks use radio signals that can be interrupted or interfered. GSM technology used in digital cellular system and PCS-based systems, operates in the 900-MHz, 1800-MHz and WCDMA 2100 bands in Europe and Asia and in the 1900MHz band in the United States are some of the mobile phone networks. Jammers can broadcast on any mobile network frequency and are effective against WCDMA, GSM and DCS. This project discussed the design and development of GSM Mobile jammer which can avail the solution to problems stated earlier.
To come up with the above system, we carried out researches that enabled us to attain appropriate designs and there after the design, we were able to construct/build different parts of the system and interconnect them as one unit. Finally the system was tested for functionality, results were arrived at which fulfilled the concept of jamming by releasing same frequency as the one from BTS.
