Digital Train Solution

Future of Singapore’s Mass Transit System

Huawei’s Digital Train Solution automates processes and delivers services for the railway industry, providing reliable train-ground backhaul, high-density Wi-Fi coverage, and an onboard platform to keep pace with passenger demands for mobile Internet services. Huawei helps rail operators focusing on wireless communication and automated train control to overcome challenges such as:

  • Railways lack a high-density network that can provide reliable, continuous coverage for increasing mobile demands
  • Most onboard services are offline and lack real-time operation capabilities
  • Railways traverse complicated environments with numerous communications standards


Huawei developed its Digital Train Solution to deliver advancements in railway communications, including broadband ground-vehicle reliable backhaul, high-density Wi-Fi coverage, and onboard open platform. These innovations enable the rail industry to enrich the mobile travel experience for passengers and refine operations.

Reliable train-ground backhaul

LTE networks are deployed along railway lines, around railway stations, and in rolling stock depots. Locomotive status data is transmitted through the LTE networks in real-time to the central locomotive monitoring platform for processing. If abnormalities are detected, preventative measures are invoked to reduce waste and improve efficiency. In addition, network deployment is simplified as standard GSM cellular technology for Rail (GSM-R) and LTE networks share base stations and other network infrastructure. Multiple communications standards are supported along the entire railway line.

High-density Wi-Fi coverage

A number of proprietary Huawei technologies are used to enable Wi-Fi coverage on trains with high passenger density, including Clear Channel Assessment (CCA) optimization, offline control, and multi-user scheduling. Flexible networking is supported for various trains. The Wireless Distribution System (WDS) and mesh networking schemes can be implemented on new deployments or to change old train networks.

Easy scalability for onboard services

Huawei’s onboard gateway AR511 is integrated with the Android platform, has open standards, and can be flexibly configured to support third-party value-added services such as energy consumption monitoring and ticket booking.

Huawei Digital Train solution helps railway operators build a high-bandwidth train-ground communications platform with wireless onboard services for passengers to improve their travel experience and real-time locomotive status monitoring to improve operations.
