Product Description
DDLmesh Wireless Mesh/Data Link Handheld & Backpack Series
Ultra Long Range, Low Latency, Low Cost HD Video & Distant Data Transmission Multi-channel Data Link
Product Overview
The DDLmesh series wireless digital data link is a low-cost, long-distance video and data transmission solution featuring compact size, lightweight design, 2×2 MIMO technology, comprehensive functionality, and multiple frequency bands. Built on an SDR software-defined radio platform with 2×2 MIMO, it incorporates advanced technologies including Beamforming, Maximal Ratio Combining (MRC), Maximal Likelihood (ML) algorithm, low density parity check (LDPC) coding, intelligent frequency selection, and autonomous frequency hopping for superior RF performance and robust anti-jamming capabilities.
This data link radio provides ultra-long distance, low latency, bidirectional multi-channel network video, data, and voice integrated wireless transmission. Featuring world-leading code-modulated physical layer waveform technology with flexible anti-jamming and secure encryption design, it delivers reliable remote data links for UAVs, helicopters, robots, unmanned ships, unmanned vehicles, and special vehicles.
System Configuration
The application system consists of airborne radio with airborne camera, ground radio with ground computer, and necessary accessories including power supply, antenna feed system, connection lines, and connectors. The system can simultaneously transmit three IP/HDMI/SDI/CVBS HD video streams and multiple two-way transparent data channels (flight control/pod, BD/GPS, voice, etc.) with AES encryption ensuring transmission security. Transmission power can reach up to 40W, providing stable and reliable communication links.
