Maritime Ship Wireless Transmission Solution

I. Industry Background and Challenges

As a major coastal and border defense nation, China boasts over 18,000 kilometers of continental coastline and vast maritime territories. The complex and dynamic marine environment makes real-time monitoring through traditional networks challenging. During missions in uncovered areas (e.g., border control, coastal defense, and maritime support), border and coastal defense forces urgently require rapid deployment of efficient communication systems to ensure seamless transmission of critical services such as video, voice, and command dispatching, thereby enhancing emergency response capabilities and safeguarding personnel and operations.

II. Application Scenarios and Requirements

1. Existing Communication Systems

Current maritime communication networks rely on the following technologies:

  • Maritime Wireless Communication: Covers near-shore vessel-to-shore interactions;
  • Satellite Communication: Supports offshore and oceanic communication needs;
  • Shore-based Mobile Communication: Provides regional supplementary coverage.
  • This system is widely used in maritime supervision, oil and gas exploration, and marine research. However, challenges remain, including limited interoperability and flexibility.

2. Core Requirements

  • Rapid Networking: Establish a decentralized dynamic network without relying on public infrastructure;
  • High Reliability: Ensure stable communication links in complex environments;
  • Multi-service Support: Simultaneous transmission of video, voice, and command data;
  • Security and Control: Data encryption and network protection capabilities;
  • Flexible Scalability: Support dynamic node addition/removal and relay-based expansion.

Andaxu’s self-organizing network (SON) communication system excels in non-line-of-sight transmission. It enables rapid formation of a decentralized network through Andaxu MESH products without relying on public facilities (e.g., power grids or networks). All node locations and statuses are aggregated in real time to a backend management system for unified scheduling, management, and control.

III. Core Advantages of the Solution

1. Intelligent Mesh Self-Organizing Network Technology

  • Dynamic Networking: Devices automatically search for nodes upon startup, supporting direct/multi-hop connections without pre-configuration;
  • Decentralized Architecture: No reliance on base stations, with self-healing and self-balancing capabilities to ensure uninterrupted communication even during node failures;
  • Non-Line-of-Sight Transmission: Overcomes terrain and obstacle limitations, adapting to complex maritime environments.

2. High Bandwidth and Long-Distance Transmission

  • Extended Coverage: Point-to-point transmission distance ≥50 km, expandable via multi-hop relays;
  • High Speed: Peak rate of 150 Mbps, with COFDM technology enabling 70 Mbps throughput to support simultaneous HD video streams.

3. Multi-Layered Security

  • Hardware Binding: Unique MAC address authentication for nodes;
  • Network Encryption: AES128/AES256 encryption ensures data security;
  • Hierarchical Protection: Third-party devices enhance network access control to prevent unauthorized intrusion.

4. Full-Service Compatibility and Flexibility

  • Multi-Service Support: Voice intercom, HD video, document transmission, and WiFi terminal access;
  • Open Protocol: Full IP transparent transmission, compatible with TCP/IP for seamless integration with command systems or public networks;
  • Rapid Customization: Modular design supports on-demand functional expansion and quick deployment for mobile operations.

IV. Solution Value

This solution leverages Mesh SON technology and high-reliability design to achieve:

  • Enhanced Emergency Response: Rapid deployment of temporary networks to accelerate mission readiness;
  • Improved Coordination: Break communication barriers among ships, islands, and shore-based units;
  • Ensured Continuity: Automatic link switching in complex environments to minimize downtime;
  • Cost Reduction: Reduce reliance on high-cost satellite communication and optimize resource allocation.
