The MatThe Matrice 350 RTK uses the O3 wireless transmission industry version, supporting three-channel 1080p high-definition transmission[5] with a transmission distance of up to 20 kilometers[6]. Both the aircraft and the remote controller are equipped with a four-antenna transceiver system, which can intelligently select the two antennas with the best signal strength to transmit signals and simultaneously receive signals from all four antennas. This significantly enhances anti-interference capabilities and ensures more stable transmission. Moreover, the O3 video transmission signal can also work in conjunction with the 4G network[7]. When the O3 video transmission signal is interfered with, the MatThe Matrice 350 RTK can still ensure the stability of video transmission through the 4G network and can easily cope with signal interruption in complex environments such as urban buildings.
