Anti-Interference UAV Video & Data Link Module
Overview
The DV2111 Anti-Interference UAV Video & Data Link Module is a compact, lightweight wireless communication solution designed for industrial drones and other unmanned systems operating in challenging RF environments. It combines HD video transmission with bidirectional data communication, helping maintain a reliable connection between airborne equipment and ground control stations.
Operating in the 1350–1450 MHz frequency band, the DV2111 uses adaptive modulation, interference detection, forward error correction, and dynamic link adaptation to improve communication reliability as channel conditions change.
With dual-channel 500 mW transmission, support for Ethernet, RS232, TTL, and SBUS, and a specified line-of-sight communication range of 30–50 km, this module is suitable for long-range UAV video and telemetry applications.
