Product Detail


●Self-Forming and Self-Healing Capabilities

FD-61MN builds a continually adapting mesh network, which allows nodes to join or leave at any time, with a unique decentralized architecture that provides continuity even when one or more nodes are lost.

Strong stable data transmission ability
Using coding adaptive technology to automatically switch coding and modulation mechanisms according to signal quality to avoid large jitter in the transmission rate as the signal changes.

●Long Range Communication

1. Strong NLOS Ability
2. For unmanned ground vehicles, non-line-of-sight 1km-3km
3. For unmanned aerial vehicles, air to ground 10km

Precisely Control UAV Swarm Or UGV Fleet

Serial port 1: Sending and receiving (serial data) through IP (address + port) in this way, one control center can precisely control multiple units UAV or UGV.
Serial port 2: Transparent transmission and broadcast sending and receiving control data

●Easy Management
1. Management software to manage all the nodes and monitoring the real time topology, SNR, RSSI, distance between nodes, etc.
2. API provided for third-party unmanned platform integration
3. Self-organizing network and not require user interaction during working

Frequency hopping, adaptive modulation, adaptive RF transmitting power and MANET routing ensures connectivity also during electronic warfare conditions.
