CitationI recently had a strong interest in software-defined radio technology (SDR), and I was interested in one of the popular SDR platforms (HACKRF), which received a range of frequencies between 1MHz ~6ghz (wider). There is also a need to mention an interesting and useful attack method, that is, to re-send the attack, of course, it can be understood to record a simple signal, and then broadcast it. I wil
