Overview
This system adopts a new type of broadband “wireless mesh network” based on mesh networking.
As a mobile self-organizing network, this product does not depend on the existing network infrastructure and supports any network topology. Unlike traditional wireless networks, it is a centerless, distributed, multi-hop relay, dynamic routing, and invulnerable The wireless broadband system with strong performance and good scalability uses its own routing protocol internally to complete the wireless communication between nodes through wireless multi-hop forwarding. An ad hoc distributed broadband wireless network transmission system with an efficient MAC layer transmission protocol and a two-layer routing protocol.
All nodes are completely peer-to-peer without any infrastructure. It can quickly build a dedicated self-organizing network between mobile nodes, provide instant adaptive communication, have excellent broadband performance, and support real-time transmission of multimedia information such as video coding and audio coding. The system technology has the advantages of strong anti-interference ability, high spectrum efficiency, long transmission distance, anti-fading ability, and strong diffraction ability.
It can realize real-time and high-quality wireless two-way data transmission functions in complex and non-line-of-sight environments.
For emergency individual soldiers and vehicle-mounted platform information communication transmission in complex environments, we follow the design principles of generalization, modularization, and standardization to realize the information coordination and interaction function of personnel on duty, and the system can work continuously, stably, and reliably for a long time.
