DdlMesh Wireless Digital Data Link Series – Ultra-Low Latency, Long-Range, Multi-Channel Bidirectional Radio
Ultra low delay, Long range,Bidirectional multi channel Radio
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 based on 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.
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 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.
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.).
The system can simultaneously transmit three IP/HDMI/SDI/CVBS HD video and multiple two-way transparent data(such as flight control/pod, BD/GPS, voice, etc.). AES encryption ensures transmission security.
Radio the transmission power of the station can reach up to 40W, providing a stable and reliable communication link.
