Advanced Broadband Digital Data Link For Unmanned Systems In Tri-Bands

The FDM-66MN is an advanced broadband digital data link designed for secure wireless communication in mobile robotics and unmanned systems. It supports triple frequency bands—800MHz, 1.4GHz, and 2.4GHz—and can be managed via software for frequency selection, offering flexibility in various operational environments.

Key Features:

Triple Frequency Support: Selectable 800MHz, 1.4GHz, and 2.4GHz frequency bands to adapt to different communication needs and environments.

• Long-Range and High-Throughput: Provides reliable wireless video and telemetry communications with high throughput, ideal for both NLOS (Non-Line-of-Sight) and long-range applications.

• Secure Communication: Ensures secure data transmission for critical applications, making it suitable for sensitive operations like surveillance or inspection.

• IP-Based Serial Data Transmission: Allows control stations to manage and control multiple mobile robots (UGVs, drones, etc.) by transmitting serial data via IP addresses.

• Compact Design: With a size of 60 x 55 x 5.7mm, it is the smallest OEM wideband radio module, making it ideal for integration into small unmanned systems.

• Versatile Applications: Well-suited for use in swarming drones, UGVs, and other robotic systems, especially in environments such as indoor building inspections or tunnel explorations where traditional communication systems may not be viable.

Conclusion:

The FDM-66MN offers a compact, high-performance solution for secure wireless communication in mobile robotics and unmanned systems, particularly in challenging environments such as indoor inspections or NLOS scenarios. Its small form factor and triple frequency support make it an ideal choice for system integration into small drones, UGVs, and other mobile autonomous units.
