## 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.

### COFDM vs. Conventional Radio — Key Differences

| Capability | COFDM | Conventional |
|---|---|---|
| Subcarrier count | Hundreds | 1 |
| NLOS capability | Strong | Poor |
| Multipath resistance | Excellent | None |
| Mobility support | High-speed | Stationary only |
| Spectrum efficiency | High | Low |

### Technology Highlights

**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.

## Sectors Served

- **Military & Defense** — Tactical MANET mesh, soldier-worn radios, encrypted data links for combat operations.
- **Public Safety & Fire** — Ad-hoc networks for first responders, firefighting, disaster response, and emergency command.
- **Unmanned Systems** — Low-latency COFDM drone downlinks, UAV telemetry, and relay node integration for aerial operations.
- **Broadcast & Media** — HD 1080P live relay transmission for sports, news, and remote broadcast environments.

## Deployment Process

1. **Assess** — We analyze your operational environment, frequency requirements, range, data payload, and security constraints.
2. **Design** — System architecture is configured — waveform, topology, antenna type, power level, and encryption protocol.
3. **Deploy** — Equipment is delivered tested and pre-configured. Plug-and-play setup minimizes on-site integration time.
4. **Support** — Ongoing technical support, firmware updates, and customization for evolving mission requirements.

## Application Cases

- **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.
