Autonomous Mobile System for Detecting and Jamming Cellular Network Signals Using a Software Defined Radio Integrated into a UAV Platform

The article presents a built-up model of a system for detecting and jamming radio communication in 2G / 3G / 4G / 5G cellular systems installed on an Unmanned Aerial Vehicle (UAV). The proposed approach was built according to a modular concept to increase its reliability, ease of changing individual components, possible quick technological upgrade, and accessible porting equipment to various mobile platforms. All used elements are the Commercial Off The Shelf (COTS) type. The used platform is a UAV that provides several advantages for the proposed solution, such as very high mobility, remote work, and the possibility of autonomous flight. All components have been integrated, and the developed proprietary application is used to define the mission's parameters and illustrate the current electromagnetic environment situation for the monitored frequency band of cellular systems. The proposed system can be included in the military operational and reconnaissance solutions category. After a short introduction and justification of the work undertaken, the developed concept, components of the proposed system, and then the solution implementation was presented. The research was conducted for the selected test scenario, which was used to develop conclusions and plan further work to develop a jammer operating in a smart manner.
