Encrypted Data Transmission.

The Air-Link, 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.

Point to Point

Air Link

Safe and reliable

While point-to-point communication is susceptible to interference, Air-Link maintains stable communication within signal coverage.

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.
