Autel SkyLink Image Transmission Function
The Autel Alpha aircraft is equipped with Autel SkyLink 3.0 image transmission technology and
has 4 image transmission antennas, with 2 channels of transmitting signals and 4 channels of
receiving signals, so that the communication distance between the aircraft and the remote
controller can reach up to 15 kilometers.
It supports adaptive frequency hopping transmission of multiple frequency bands, selects the
optimal channel according to the electromagnetic interference situation, and has strong anti-
interference ability.
The quality of real-time transmission reaches 1080p/30fps, and it has a high transmission bit
rate of 64Mbps and low-latency transmission characteristics.
Data link transmission uses AES-128 encryption, and data storage uses AES-256 encryption to
ensure end-to-end data security.
