Why COFDM & MANET?
Our systems are built on Coded Orthogonal Frequency Division Multiplexing (COFDM), the gold standard for wireless transmission in complex real-world environments where conventional radio fails.
Multipath Immunity
Spreads data across hundreds of subcarriers. When some are disrupted by reflections or obstructions, the rest carry the signal — no full link failure.
NLOS Non-Line-of-Sight
Maintains reliable links through buildings, terrain, and foliage where line-of-sight systems collapse entirely.
Self-Organizing MANET Mesh
Nodes automatically discover each other, form routes, and reroute in real time during movement — no fixed infrastructure required.
Military-Grade Encryption
AES 128/256 encryption with dynamic key management across all product lines as standard.
From Requirement to Deployment
Assess
We analyze your operational environment, frequency requirements, range, data payload, and security constraints.
Design
System architecture is configured — waveform, topology, antenna type, power level, and encryption protocol.
Deploy
Equipment is delivered tested and pre-configured. Plug-and-play setup minimizes on-site integration time.
Support
Ongoing technical support, firmware updates, and customization for evolving mission requirements.
Real-World Deployments
Fire & Emergency Rescue
Ad-hoc mesh networks enable frontline firefighters and commanders to share audio, video, and positioning data without fixed infrastructure — even inside structures.
Remote Power & Utility
Maintenance teams in signal-dead zones carry manpack MANET nodes. Video, sensor data, and voice relay to command centers via satellite or 4G/5G backhaul.
UAV Aerial Relay
Drones equipped with OEM COFDM boards extend ground mesh networks, provide aerial observation, and act as multi-hop relay nodes for terrain-obstructed areas.
Live Broadcast & TV Relay
Full HD 1080P transmission from mobile crews to broadcast trucks, deployed by TV organizations including international clients for on-location live coverage.
Maritime & Flood Control
Vehicle-mounted and manpack systems provide real-time video and data for water authority operations, coast guard patrols, and flood response coordination.
Industrial Automation
OEM modules and Ethernet broadband links deliver low-latency control data for industrial robots, automated production lines, and remote equipment monitoring.
