'''GNU Radio''' is a [[free software]] development toolkit that provides signal processing blocks to implement [[software-defined radio]]s and [[signal processing]] systems. It can be used with external [[radio frequency]] (RF) hardware to create software-defined radios, or without hardware in a simulation-like environment. It is widely used in hobbyist, academic, and commercial environments to support both wireless communications research and real-world radio systems.
