Secure Wireless UGV/Drone Data Links for NLOS Communications

Model: FDM-66MN

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.

Obtain serial port information via IP allows one control station to control multiple mobile robotics. It is particularly suited to use on swarming drones, UGV, unmanded vehicles and other short to medium range robotics applications.

60*55*5.7mm size makes it the smallest OEM wideband radio module and ideal candidate for system integration into small unmanned systems to perform in challenging environments, like indoor inspection of buildings or tunnels.
