Future Railway Mobile Communication System (FRMCS)

Ensure safe, dependable operations with FRMCS based on 5G

Put your railway on the fast track to the FRMCS with our proven 5G solutions, railway communications expertise and Nokia Bell Labs innovations. Our comprehensive approach will help you modernize your GSM-R networks and take your operations into the digital age.


What is FRMCS?

FRMCS is set to become the global standard that will revolutionize railway communications. This mobile broadband-ready technology will enable you to improve safety and operational efficiency, support innovative passenger services and accelerate your digital transformation, all of which will help you compete for travelers. FRMCS also minimizes network latency and uses cloud technology, which will help you automate train operation and support broadband M2M communication.


5G is a critical enabler for FRMCS

5G can help you get the most from FRMCS migration. It offers high capacity, performance and reliability, along with support for massive MTC and IoT. With FRMCS based on 5G, you can support ultra-reliable, low-latency mission-critical communications. And you can build a platform for innovative applications – from group video calling and automated train control to predictive maintenance and fast on-board Wi-Fi – that will reduce operating costs and enhance the passenger experience.

The right architecture for 5G FRMCS

Clear your path to 5G and FRMCS by providing an intelligent and dynamic communications platform that supports all railway systems, processes and activities. It will enable you to create new efficiencies and support new applications by providing secure and reliable connectivity for people, sensors, trains, video monitors and automated train control systems.

Features and benefits

Our solutions accelerate your digital transformation and help you prepare for the future by giving you more flexibility to meet the performance, reliability and connectivity requirements of FRMCS.

Support multiple spectrum bands

Take advantage of any available spectrum band between 600 MHz and 90 GHz, including licensed, shared access and unlicensed FDD and TDD bands.

Maintain the highest reliability

Ensure up to 99.9999 percent availability with a network that supports capabilities such as path redundancy, stateful virtualization and cloud core concepts. Our solutions also support 5G ultra-reliable low-latency communication (URLLC), a critical enabler for mission-critical communication and automation applications.

Use multiple access technologies

Flexibly support 3GPP and non-3GPP access technologies simultaneously. Our solutions support LTE, 5G, Wi-Fi and satellite connectivity and ensure a smooth migration to 5G.

Meet new critical communication demands

Prepare for mission-critical communication needs. Our solutions support LTE and 5G QoS features and ease application integration.

Shift to distributed networking

Boost scalability, performance and flexibility with an architecture that supports centralized and distributed deployment options. With a distributed deployment, you can deliver the ultra-low latency required for applications such as CCTV and video analytics.

Strengthen your cyber defense

Keep your networks, communications, assets and devices safe with an end-to-end security approach that combines a variety of techniques to provide an in-depth defense against cyberattacks.

Prioritize QoS for critical applications

Provide guaranteed bit rates for mission-critical services with flexible flow-based QoS, a 5G capability that separates critical and non-critical applications and data.

Slice your network

Use one common network infrastructure to provide cost-effective support for a wide range of railway applications. With 5G network slicing, you can create separate, dedicated railway operator networks or use public mobile operator slices to run non-mission-critical services.

Maintain performance at high speeds

Compensate for Doppler effects with features that ensure that your communication systems can perform reliably at speeds of more than 500 km/h.
