Custom Product

As part of a major rail transit modernization project in China, we developed a customized high-performance 5G communication solution deeply integrated into the train control and management system. The project required a reliable “train-to-ground” data transmission architecture capable of supporting continuous real-time communication between moving trains and station data centers.

By leveraging the high bandwidth and ultra-low latency characteristics of 5G technology, the system enables automatic real-time upload of operational data, including train status, onboard diagnostics, environmental monitoring, and equipment performance metrics. Maintenance teams can now analyze massive volumes of data instantly, shifting from reactive troubleshooting to predictive maintenance strategies. This significantly reduces operational risks, lowers maintenance workload, and improves fault diagnosis and response efficiency.

Custom Hardware Development Challenges

Unlike standard industrial communication deployments, rail transit environments impose extremely demanding requirements on hardware reliability, electromagnetic compatibility, and long-term operational stability. During product development, several key challenges had to be addressed:

• High-Speed Mobility Stability
  Maintaining uninterrupted 5G connectivity under high-speed train movement required extensive RF optimization and antenna tuning to ensure stable handovers between base stations.

• Harsh Electromagnetic Environment
  The onboard electrical systems generated strong electromagnetic interference. Additional shielding design and EMC optimization were implemented to guarantee communication reliability.

• Wide Temperature and Vibration Resistance
  Railway equipment operates continuously under vibration, shock, and fluctuating temperatures. The hardware platform was reinforced with industrial-grade components and enhanced structural protection.

• Deep System Integration
  The communication module needed to interface seamlessly with existing train control systems and legacy infrastructure while maintaining strict data transmission reliability and cybersecurity requirements.

• Real-Time Data Reliability
  Critical operational data could not tolerate packet loss or latency spikes. The solution incorporated optimized network failover mechanisms and edge-side buffering strategies to maintain data integrity.

Project Outcome

The customized 5G communication platform successfully improved operational visibility and enabled smarter railway maintenance management. The deployment demonstrated how tailored industrial communication hardware can accelerate the digital transformation of modern rail transportation systems while meeting stringent industry reliability standards.
