The GSM, DCS, UMTS and LTE systems which constitute a very vast telecommunication world remain in continuous evolution with regard to the greatest number of regions and sites coverage in Cote dIvoire. All these cell phone systems use radio signal that can be completely interrupted for specific goals. Indeed, at ESATIC, a project has enabled the design and implementation of a simple and inexpensive mobile phone jammer that aims to provide a solution to the cheating problem through cell phones during students national exams. The Denial of Service (DOS) jamming technique which blocks communications absolutely has been used to implement this device. Here, the jamming principle consists in releasing an important noise at the same frequency as that used by the mobile operator in order to completely block the user signal. In fact, satisfactory jamming of the various mobile signals has been observed by blocking these signals in the jammer action areas. The experiment was carried out on the 2G, 3G and 4G networks operated by the three main national operators: ETISALAT, MTN and ORANGE. However, the general recommendation of this project is to use higher capacity power amplifiers to achieve the effective range of 50 meters, especially for DCS 1800, UMTS 2100 and LTE 2600 systems.
