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.
