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.

01

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.

02

NLOS Non-Line-of-Sight

Maintains reliable links through buildings, terrain, and foliage where line-of-sight systems collapse entirely.

03

Self-Organizing MANET Mesh

Nodes automatically discover each other, form routes, and reroute in real time during movement — no fixed infrastructure required.

04

Military-Grade Encryption

AES 128/256 encryption with dynamic key management across all product lines as standard.

COFDM vs. Conventional Radio — Key Differences
Subcarrier count Hundreds vs. 1
NLOS capability Strong vs. Poor
Multipath resistance Excellent vs. None
Mobility support High-speed movement OK
Narrowband operation 1–8 MHz
Link recovery Auto re-route
Encryption standard AES 128 / 256
Protocol Standard TCP/IP
