jammer

With the development of drones, new changes have been brought to society. It not only penetrates into multiple scenes such as aerial photography, commercial performances, leisure and entertainment, but also enriches the service content and form of the consumer industry. But at the same time, it also brings hidden dangers to social security. Unsafe factors such as secret photography, transportation of drugs, and illegal flights are increasingly threatening public security. Therefore, drone confrontation has increasingly become an indispensable consideration in major venues such as public security, railways, urban security, forests, prisons, industrial areas, and sports events. So what is drone jamming?

Most of the control signals used by the drone jammer system are in conventional civil frequency bands such as 2.4GHz and 5.8GHz. With the rapid development of open source hardware and the popularization of software-defined radio technology, the technology to crack the UAV radio communication protocol has gradually developed. This technology is one of the advanced technologies in the field of UAV confrontation at home and abroad. By cracking the UAV signal communication protocol, imitating the remote control to send control signals to the UAV without affecting the normal operation of other devices. However, with the improvement of communication encryption technology, it is more and more difficult to crack, and it needs to adapt to various drones on the market, and the models of drones sold need to be updated regularly, and the cost is high.
