Hocell fiber optic cellular signal jammer can disrupt mobile communication services, including voice, SMS and data, by jamming downlink signals of mobile phones. It supports jamming all frequency bands in 2G/3G/4G/5G and WIFI network modes. The solution achieves precise jamming through distributed jammers and antennas, and is highly scalable to adapt to various jamming areas by employing different number of extension. Abstract—The paper presents the existing possibilities of dis-rupting the operation of optical/optoelectronic telecommunication networks in a physical layer, distinguishing between passive and active attacks. The NE555 timer generates oscillating signals, which are tuned, amplified, and transmitted via an.
