HackRF

HackRF is an inexpensive, versatile software-defined radio (SDR) device that enables users to transmit and receive radio signals across a wide range of frequencies, from 1 MHz to 6 GHz. It essentially functions as a flexible radio receiver and transmitter, allowing experimentation with various wireless communications such as FM radio, television, GPS, and amateur radio signals. By connecting HackRF to a computer and software, users can analyze, decode, or simulate radio signals for research, development, or educational purposes. Its open-source nature encourages innovation and learning in wireless technology.
