“…Similar studies of the resistance of the 5G TDD system operating in the 3.6 GHz band to jamming, but within a narrower scope, are presented in [34], [35], [37]. In these cases, the tests concerned a 5G private network in the Standalone (SA) mode of operation.…”

under project no. UGB/22-863/2023/WAT on "Modern technologies of wireless communication and emitter localization in various system applications."ABSTRACT Fourth-generation (4G) mobile networks are successively replaced by fifth-generation (5G) ones, based on the new releases of the 3rd Generation Partnership Project (3GPP) standard. 5G generation is dedicated to civilian users and the conducted analytical work shows that it has numerous technological gaps that prevent its direct implementation in military communications systems. However, the recent armed world conflicts showed that closed or public mobile networks are willingly used by soldiers for both private and business communications, and to conduct defensive and offensive operations as well. From the military operation viewpoint, jamming both civil and military systems is one of the essential elements of electronic warfare. This paper focuses on the practical trial of low-energy and smart jamming on a 5G private network using narrowband signals, which facilitates the reduction of the available throughput, e.g. in the time division duplex -uplink (TDD-UL) by 99%, or by 82% in the frequency division duplex -downlink (FDD-DL). This type of jamming also allows for reaching up to 25 dB of energy gain comparing to barrage jamming. The authors moreover investigated jamming the Narrowband IoT radio interface using synchronized, selective jamming. The goal was to propose energy efficient methods that will allow the jammers to work longer and be mounted on a small unmanned aerial vehicle (UAV) that can operate near the gNB. The generation of low-power jamming signals in the gNB vicinity successfully hinders detecting the jammer by the enemy's electronic reconnaissance systems. The proposed solutions are compared with the test results for other types of jamming methods.INDEX TERMS Electronic warfare, low-energy jamming, narrowband jamming, NB-IoT, 5G private network, smart jamming.

“…In these cases, the tests concerned a 5G private network in the Standalone (SA) mode of operation. In [37], the authors used GNU Radio software and a SDR (Software Defined Radio) platform, USRP (Universal Software Radio Peripheral) B210 as a jammer to disrupt the 5G SA network. Three types of techniques, i.e.…”
