Why is it generally reported that the jamming effect of UAV jamming equipment on DJI Mavic Air2 is not satisfactory?

  • 2022-07-28

There are many types of UAV jamming equipment, including handheld, portable, vehicle-mounted or fixed-mounted, but some customers have reported that they are testing many brands or types of drones After interfering with the device, I always feel that the interference effect on the Mavic Air2 is good. Under the same test environment, test method, and test standard, the Mavic Air2 can be driven away or forced to land in the same mode. The interference effect (effective interference distance) is obviously lower than that of DJI Phantom 3, Phantom 4 or other drones of the same type. What is the reason for the unsatisfactory interference effect only for Mavic Air2?

The reason is actually very simple, that is, the Mavic Air2 drone uses a different frequency hopping technology than other models. UAV jamming devices are usually equipped with jamming modules for WiFi2.4G and WiFi5.8, and the frequency bands for flight control and image transmission of Mavic Air2 are frequency hopping switching between these two bands. In order to improve the anti-interference ability, its frequency hopping rate is extremely high. If the frequency sweep rate of the jamming signal emitted by the UAV jamming device is lower than the UAV's frequency hopping rate, this will significantly reduce the jamming effect.

There is another situation: there are still a few overseas versions of F in the Mavic Air2, which use the 5.3G communication frequency band. If there is no jamming module for 5.3G installed in the drone jamming device, then Naturally, there is no way to achieve effective interference.

When customers encounter the problem of unsatisfactory interference effect on DJI Mavic Air2, is there any solution? There must be a way. We will give detailed answers and explanations on how to adjust the configuration of the UAV jamming equipment and improve the jamming effect.
