Converged Communication Multi-Scenario Full-Domain Communication Assurance System: Rocket Launch Full-Link Communication Dead-Zone-Free Solution

The Converged Communication Multi-Scenario Full-Domain Communication Assurance System builds a four-layer communication architecture of "Backbone Network + Public Network Collaboration + Private Network Fallback + Extreme Emergency", covering communication requirements across all scenarios of rocket launch missions, ensuring the command link remains unobstructed throughout and instructions are delivered with precision.

I. High-Speed Optical Fiber Backbone Communication Network: Core Cornerstone for Long-Distance Communication

Leveraging the IDM OSN-5GE multi-link aggregation device to build a dedicated optical fiber communication network, establishing a high-speed transmission channel between the base command center and remote sites 800 kilometers away:

- Multi-link aggregation technology is adopted to achieve bandwidth stacking and redundant backup, ensuring low-latency, stutter-free real-time transmission of high-definition audio/video and high-volume business data;

- As the core support for long-distance cross-regional communication, it provides a stable and reliable high-speed communication link for remote observation and cross-regional command collaboration, solidifying the communication foundation for full-domain rocket launch command.

II. 4G/5G Public Network Collaborative Communication Network: Cross-Standard Converged Dispatch in Public Network Areas

Equipped with multi-mode terminals and the IDM RG-3200 converged dispatch integrated gateway, barriers between different communication standards are broken down, enabling full-terminal collaboration in public network coverage areas:

- Supports unified access and dispatch of all terminal types including digital trunking, traditional fixed-line telephones, and mobile phones, eliminating compatibility obstacles between communication devices;

- Leveraging high-speed public network bandwidth, it meets the audio/video dispatch and data interaction requirements of multiple nodes such as command centers, vehicle-mounted terminals, and on-site personnel, improving command collaboration efficiency in public network coverage areas.

III. Satellite/Ad-Hoc Network Private Network Fallback Network: Communication Assurance in Areas Without Public Network

For field, remote, and other areas without public network signals, an independent private communication network is built through satellite broadband terminals and ad-hoc network devices, achieving dead-zone-free full-domain communication:

- Satellite broadband terminals provide wide-area coverage communication capability, while ad-hoc network devices enable node interconnection in local areas; the combination of the two forms a "wide-area + local-area" private network coverage;

- It also supports interconnection and interworking of digital trunking, telephones, and mobile terminals, ensuring that command instructions are still delivered with precision in environments without public networks, guaranteeing uninterrupted communication for remote observation points and field operation scenarios.

IV. Extreme No-Network Emergency Communication: The Final Command Defense Line

Using shortwave radio stations as emergency communication relays, a narrowband voice communication link is established in extreme scenarios with completely no network coverage:

- Leveraging the anti-interference and long-distance transmission characteristics of shortwave communication to achieve stable voice transmission of command instructions;

- As the final communication guarantee in extreme environments, it ensures that when extreme communication interruptions occur during rocket launch missions, the command link can still maintain basic connectivity, providing critical support for emergency response.
