MESH Bidirectional Network Transmission System

Das Bidirektionales Netzwerkübertragungssystem MESH is an advanced wireless communication solution designed for long-distance, hohe Geschwindigkeit, and reliable data transmission in both line-of-sight (DAS) und ohne Sichtverbindung (NLOS) Umgebungen. This self-organizing network system leverages TDD-COFDM (Time Division Duplex – Coded Orthogonal Frequency Division Multiplexing) transfer protocol, providing superior performance in complex and challenging environments. Its design emphasizes Robustheit, Flexibilität, und Skalierbarkeit, making it suitable for professional UAV, UGV, USV operations, industrielle Überwachung, und Sicherheitsanwendungen.

Haupteigenschaften

1. TDD-COFDM Transfer Protocol – The system adopts a TDD-COFDM protocol, which allows simultaneous bidirectional communication with strong resilience to multipath interference, Fading, and signal obstruction. This enables stable video and data transmission even in urban or heavily forested areas.
2. Long-Distance Video Transmission – Designed to transmit images and video over long distances, the system supports distances of up to 1.5 km NLOS (non-light-of-sight) und bis zu 30 km LOS. This ensures real-time monitoring for applications such as drones, Industrieanlagen, Sicherheit, and emergency response operations.
3. Mesh Networking Capability – The system supports peer-to-peer and point-to-multipoint communication, forming a dynamic, self-organizing MESH network. Each device functions as a node that can relay signals to extend coverage and maintain connectivity in areas where direct communication is impossible.
