LTE LINK SE 4G Video & Data Transmission Module
- 60ms ultra-low latency data transmission.
- Automatic recording upon takeoff.
- HD image transmission with 250ms low latency.
- 4G signal communication, unrestricted by distance.
- Encrypted data transmission, ensuring secure communication data.






Encrypted Data Transmission.
The lLTE-LINK SE, client, and server all adopt a session-based dual-key mechanism using symmetric encryption algorithms such as CHACHA20_POLY1305 and AES_128_GCM. This ensures robust data security during drone communication, prevents data tampering and unauthorized interception, and effectively safeguards against network man-in-the-middle (MITM) attacks.


CUAV Cloud
Unlimited interconnection
Relying on the advanced 4G communication network, the anti-interference ability is strong, the data security level is high, and the area covered by the 4G signal can communicate. The client operates the drone without the limitation of distance and area, realizing the real drone networking.
Multi-client support
It not only supports CUAV self-developed client, but also supports two open source ground stations of QGroundControl and MissonPlanner, and allows users to customize the client supporting Mavlink protocol.

Flight video auto save
Built-in memory card, the aircraft will automatically record after the flight takes off and save the original video in the memory card for you to view at any time.
HD 1080P image transmission, 250ms low latency
LTE LINK SE products support 1080P real-time high-definition image transmission with low latency, ideally as low as 250ms
