Nokia, a Finnish telecoms equipment supplier, has announced that it will build an SA 5G network for the 23-kilometer line of the S-Bahn Line 21, which starts in Berliner Tor, a key transport hub in Hamburg, Germany,media reported. As part of the Digitale S-Bahn Hamburg project, the line will operate driverless trains and share data entirely through the SA 5G network by 2021.
Part of the demonstration will include automatic air transfer in the area near the Bergedorf station, which is achieved by transmitting vehicle control data via this SA 5G mobile network.
Nokia’s 5G solution is the evolution of the 3GPP 5G mobile network standard, enabling self-driving trains to share data over 5G networks. Such a system has many benefits for rail service operators and consumers, including making cross-border operations smoother, increasing rail infrastructure capacity, and increasing punctuality, resulting in an improved customer experience.
As the first of its kind, the project will serve as a case study of 5G’s maturity and future potential in providing connectivity for digital rail operations. Therefore, the results of this project are critical to the development of the 5G-based future railway mobile communication system (FRMCS) standard, which is the successor to the GSM-R standard.
Kathrin Buvac, President and Chief Strategy Officer, Nokia’s Corporate Business, said: “We are delighted to be a partner of the German Federal Railways to bring digital technology to the forefront of the S-Bahn network and rail systems in Hamburg. Together, our commitment to research, development and delivery of the world’s first 5G-based automated railway operating communications system is an important milestone to FRMCS and an important step towards Industry 4.0. “
