This kit provides the DJI Cellular Dongle and mounting bracket, enabling the aircraft to access 4G networks for Enhanced Transmission when used in conjunction with a remote controller connected to the internet. The Enhanced Transmission feature can balance O3 video transmission quality and 4G data consumption, intelligently utilizing the optimal link between the 4G network and O3 video transmission system. This ensures a separate 4G link that remains operational even if the O3 video transmission link is disconnected, allowing the Matrice 350 RTK to effortlessly overcome scenarios of signal obstruction, thus enhancing flight safety.
