Omnidirectional electromagnetic interference equipment is deployed in specific protection areas to build an all-weather no-fly zone for drones, forming a targeted and effective barrier. The system emits interference signals to block the remote control link, image transmission link and navigation signal of the unmanned aerial vehicle, forcing the unmanned aerial vehicle to make an emergency landing or drive away. Each frequency band works independently according to the software platform control, and the product is modularly designed to facilitate network deployment.
