Secure Wireless UGV/Drone Data Links for NLOS Communications Introduction FDM-66MN is the most advanced broadband digital data link designed
for mobile robotics and unmanned systems. It provides a secure
wireless link in triple frequency 800Mhz/1.4Ghz/2.4Ghz management
software selectable. FDM-66MN provides a long-range and high-throughput wireless video
and telemetry communications between one or more mobile units and a
control station in off-grid and disconnected environments. Key Features High Data Rate • Uplink and downlink 30Mbps Long Communication Distance • -Line of Sight (NLOS) and mobile environments: 500meters-3km • Air to ground line of sight: 10-15km • Extend the communication distance via adding power amplifier • External RF amplifiers support (provision for manual) High Security • Using proprietary waveforms in addition to AES 128 encryption Easy Integration • With standard interfaces and protocols • 3*Ethernet port for connecting external IP devices • OEM module for easy integration into various platform, and a
standalone connectivity solution. API Document Provided • FDM-66MN provides API for compatible with different operating
systems and platforms Low Latency • Slave node - master node transmission delay <=30ms Unrivaled Sensitivity • -103dbm/10MHz

Application The miniature, lightweight and software-defined radio link module
is a reliable communication partner for unmanned applications for
Unmanned BVLoS missions, UGV, Robotics, UAS and USV. The high
speed, long range capabilities of FDM-66MN allow simultaneous high
quality duplex transmission of multiple full HD video feed and
control and telemetry data. With external power amplifer, it can
provides a 50km long rang communication. Even work in crowded city
non-line-of-sight environment, it can also ensure more 20km
communication distance.
