As public transportation including metro, light rail and BRT accelerates digital transformation, stable high-speed network communication has become increasingly critical. Such scenarios feature harsh environments and mission‑critical services, where traditional devices often cause network congestion, downtime and security risks. This paper presents an integrated solution based on industrial‑grade switches and fiber transceivers to overcome these pain points. It summarizes core challenges including severe environment, high reliability, high bandwidth & low latency, compliance & security and flexible deployment requirements.
With the digital transformation of public transportation (metro, light rail, BRT), the demand for stable, high-speed network communication is increasingly urgent. Public transportation scenarios feature harsh environments (vibration, EMI, wide temperature fluctuations) and mission-critical services (train control, HD surveillance, PIS). Traditional equipment fails to adapt, causing congestion, downtime and security risks. An integrated solution based on industrial-grade switches and fiber transceivers has been developed to address these issues.
Core Challenges in Public Transportation Network Communication
Public transportation networks face unique challenges different from conventional networks:
Harsh Environment: On-board/wayside equipment must withstand -40℃~+75℃ temperatures, vibration, EMI, dust and moisture, which ordinary commercial equipment cannot handle.
High Reliability: Mission-critical services (CBTC, surveillance) require 24/7 operation; legacy networks lack redundancy, leading to prolonged downtime.
High Bandwidth & Low Latency: 4K surveillance and real-time data demand high bandwidth, while train control needs millisecond-level latency, beyond traditional gigabit equipment.
Compliance & Security: Equipment must meet EN50155, EN50121 and CRCC standards; network security against unauthorized access is critical.
Flexible Deployment: Large coverage requires flexible, easy-to-maintain equipment for diverse scenarios (on-board, wayside, tunnel).
