Introduction

Saudi Railway Company (SAR) and Ericsson have agreed to incorporate 5G technology into SAR’s rail operations through a memorandum of understanding (MoU).

5G Technology Implementation

The MoU establishes a framework for the deployment of advanced 5G infrastructure and Future Railway Mobile Communication Systems (FRMCS). This initiative aligns with Saudi Arabia’s National Transport and Logistics Strategy, under Vision 2030.

Ericsson’s Role and Scope

Ericsson will furnish 5G solutions, infrastructure, and technical expertise to enhance SAR’s rail network communications. The aim is to establish secure and dependable 5G services essential for rail operations.

Planned Developments and Applications

The collaboration involves developing and testing FRMCS-based applications, high-speed passenger broadband solutions, and digital tools. These tools are intended for train control, staff communications, real-time video streaming, and onboard Internet of Things (IoT) connectivity. Additional plans include establishing a laboratory or innovation centre to validate 5G applications within a rail environment and providing training programmes to equip SAR staff with skills in FRMCS and 5G technologies.

Operational Deployment and Infrastructure Updates

The partnership includes a trial deployment of technology on an operational SAR railway line to evaluate system integration and performance. The legacy GSM-R communication system will be replaced with 5G technology. FRMCS is slated for deployment across approximately 200,000 km of mainline railways to modernize communication and operations.
