Ultra Long-Range Wireless Mesh/Data Link - HD Video & Data Transmission by China Suppliers and Factory
The new DDLmesh series wireless digital data link is a low-cost long-distance video & data transmission product featuring small size, light weight, 2×2 MIMO, complete functions, and abundant frequency bands. 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 robust anti-jamming capabilities.
DDLmesh series data link radio provides ultra-long distance, low latency, bidirectional multi-channel network video & data & voice integrated wireless transmission. The world's leading code-modulated physical layer waveform technology, combined with flexible anti-jamming and secure encryption design, makes it ideal for reliable remote data links in UAVs, helicopters, robots, unmanned ships, unmanned vehicles, and special vehicles.
