Jamming detection systems are vital in environments relying on wireless connectivity, such as industrial control systems, smart cities, and military operations. These systems often employ spectrum analyzers and specialized algorithms to monitor radio frequencies for anomalies. For instance, in a drone delivery network, jamming detection can alert operators to attempts to disrupt drone navigation or communication with ground control.
