The history of Software-Defined Radios (SDRs) is a captivating journey, evolving from a conceptual idea into a game-changer for wireless communication during the late 20th and early 21st centuries. Originally envisioned for military and defense purposes, SDRs rapidly expanded their influence, revolutionizing civilian communication. The proposed work includes applications like Spectrum Scanning, which enables real-time monitoring and optimization of the radio frequency spectrum and passive microwave remote sensing by finding signals of opportunity, Contraband Cellphone Detection, enhancing security efforts in detecting unauthorized cellphones in secure facilities, and Human Activity Recognition through Wi-Fi signals. SDRs, with their flexibility, provide valuable information about human activities within physical spaces, from smart building management to healthcare — offering potentially life-saving applications, particularly in environments like nursing homes.
