Ultra Long Range Low Latency Data Radio: China Factory Suppliers for DDLmesh Wireless Mesh HD Video & Data Link Solutions
Next-Generation Wireless Digital Data Link
The new DDLmesh series wireless digital data link is a low-cost long-distance video & data transmission product with small size, light weight, 2×2 MIMO, complete functions and abundant frequency bands. DDLmesh series is based on the SDR software defined radio platform with 2×2 MIMO. It adopts Beamforming, Maximal Ratio Combining (MRC), Maximal Likelihood (ML) algorithm, low density parity check (LDPC) coding, intelligent frequency selection, and autonomous frequency hopping technology to achieve strong radio frequency performance and strong anti-jamming capabilities.
DDLmesh series data link radio provides ultra-long distance, low latency, bidirectional multi-channel network video, data, and voice integrated wireless transmission. The world's leading code-modulated physical layer waveform technology and flexible anti-jamming and secure encryption design for the unmanned field are applied to reliable remote data links for UAVs, helicopters, robots, unmanned ships, unmanned vehicles, and special vehicles.
System Composition:
The application system is mainly composed of the airborne radio with the airborne camera, and the ground radio with the ground computer, as well as the necessary accessories (including power supply, antenna feed system, connection lines, and connectors, etc.).
Transmission Capabilities:
The system can simultaneously transmit three IP/HDMI/SDI/CVBS HD videos and multiple two-way transparent data (such as flight control/pod, BD/GPS, voice, etc.). AES encryption ensures transmission security. The transmission power of the station can reach up to 40W, providing a stable and reliable communication link.
