3.11 Aircraft Communication Frequency Bands

The EVO Lite Enterprise Series multi-rotor drone is equipped with Autel SkyLink transmission technology, equipped with triple-frequency dual-transmit dual-receive capability, so that the communication distance between the aircraft and the RC can reach up to 12km. PDF p. 62

The system supports adaptive frequency hopping transmission across multiple frequency bands, selecting the optimal channel based on electromagnetic interference conditions and providing robust anti-interference capabilities. PDF p. 62

Real-time transmission quality reaches 1080p@30FPS, with a high transmission bitrate of 64Mbps and low-latency transmission characteristics. PDF p. 62

Data link transmission adopts AES-128 encryption method and data storage AES-256 encryption method, ensuring end-to-end data security. PDF p. 62

The transmission data is based on the RC and comes from test data, and the test environment and conditions are different, and the data may be different. PDF p. 62

The transmission range is provided for reference only, and during actual use, it is important to monitor the quality of the video transmission signal continuously. In the case of poor video transmission signals, it is recommended to promptly reduce the flight radius. For more information, please refer to “6.3 Status Notification Bar” in Chapter 6. PDF p. 62

In actual use, after the aircraft and the remote controller is turned on and matched in frequency, the flight application in the remote controller will automatically determine and select the radio communication frequency band that complies with local regulations for the specific country or region based on the GNSS information received by the aircraft. PDF p. 62

Before flight, please ensure that the aircraft receives a strong GNSS signal after being powered on. This allows the flight application to receive the proper communication frequency band. PDF p. 62

When the aircraft does not obtain GNSS positioning information after being turned on (for example, the aircraft enters visual positioning mode or attitude mode right after being turned on), the radio communication frequency band between the RC and the aircraft adopts 2.4G frequency band by default; when the aircraft enters the visual positioning mode or attitude mode from GNSS mode, its communication frequency band remains the same. PDF p. 62

The communication frequency bands of the aircraft comply with regulatory requirements worldwide. Please feel assured in using it. The relevant used frequency bands are listed in the table below. PDF p. 62

Users can choose legal image transmission frequency bands in the flight application on their own. For details, please refer to “6.5.4 Image Transmission Settings” in chapter 6. PDF p. 63

Some countries and regions have strict restrictions on the use of radio communication frequency bands. It is crucial to use them legally, and any modification of communication modules is strictly prohibited. PDF p. 63

If flying in any countries not listed in the above table, please consult the local communication management authorities to ensure that the aircraft communication frequency bands comply with local regulatory requirements. PDF p. 63

UAS will automatically match the legal frequency band based on GNSS positioning, so users can use it with confidence. PDF p. 63

The aircraft supports frequency matching with the RC, enabling remote communication control of the aircraft. PDF p. 63
