In recent years, the use of unmanned aerial vehicles has entered all walks of life, and has also fallen from tall products to ordinary people's homes. The large-scale use of UAVs has brought many conveniences to people's production and life. At the same time, the uncontrolled flying of UAVs brings about potential risks that can not be underestimated. Whether it is the improper operation of ground personnel or the accidents caused by UAVs themselves, personal safety and property losses may be caused. By using UAV jamming equipment, the chaos of "black flying" of UAVs can be eliminated from the source, playing a great role in some areas requiring airspace control.

At present, the government has issued a policy that when using UAVs, they need to hold a UAV flight license, and apply to the civil aviation administration for a route before the UAV takes off. They are not allowed to fly randomly. If the UAV flies above a certain height, it will pose a great threat to civil aviation aircraft, especially around the airport. In order to prevent the sudden occurrence of UAV accidents, "no fly zones" are generally set up near the airport. In addition, the UAV carries a high-definition camera. If the UAV flies into a confidential unit to make illegal video recording, it will cause immeasurable losses to the authorities and units. Therefore, the use of UAV jamming equipment in these places will prevent the UAV from further flying into the "no fly zone". No matter what brand of UAV is used for navigation and operators, it can not be separated from the support of wireless signals. The UAV jamming equipment blocks the communication mode of UAV by interfering with the wireless signals, and interferes with the data and image transmission signals of UAV to achieve the purpose of countermeasures, so as to protect the safety in the area.

Blocking UAV communication is one of the many ways of anti UAV. By blocking the signals used by some UAVs, the communication link of the UAV will be affected, and the UAV equipment will lose control or crash land. In addition, UAV jamming equipment and other technologies are still developing. Only by establishing perfect UAV countermeasures, can we truly reduce the harm caused by UAVs.
