This article discusses the deployment of a network of frequency jammers within Makala Central Prison, aimed at countering illegal communications that harm the security of the facility. The aim is to implement an effective solution to block mobile communication signals and reduce the risk of criminal coordination between inmates and outside contacts. The jamming system is equipped with advanced components, including a signal amplifier and specific antennas, allowing optimal coverage of target frequencies while minimizing external interference. Through technical analysis, this article explores aspects of deployment, such as selecting locations for maximum efficiency and managing potential impacts on neighboring infrastructure. The results show that the use of this jamming device significantly improves the security of the facility, limiting unauthorized communications and thus strengthening internal control. This article contributes to offering an innovative solution adapted to the security requirements of prison environments.
