Proxion provides measurement service for mobile networks throughout the whole 6 000 kilometre railways in Finland for Digirail

Proxion has been selected to provide a mobile network measurement service for the suitability and capability of public operators’ networks to operate as a mobile network for a new pan-European traffic management system promoted by the Digirata project.

In the tender for Fintraffic Raide Oy, an operator was sought to measure the entire public railway network managed by the Finnish Rail Administration, Väylävirasto, a total of almost 6,000 kilometers, during 2022. The pioneering nature of Proxion’s digital rail traffic services in providing a mobile metering service for the radio network ensured that the company won the competition. The agreement between Proxion and Fintraffic includes an option from 2023.

– Old radio network-based systems have been based on traditional GSM networks. With the help of our measurement service, we measure and seek confirmation that the mobile networks of public operators such as Elisa, DNA and Telia are suitable for data transmission of the new European rail traffic management system, ERTMS, describes Kimmo Kolehmainen, Project manager for mobile 5G-laboratory at Proxion.

One of the goals of the Digirata alliance project between Fintraffic and the Finnish Railways is that the ERTMS system can be implemented on the mobile networks of public operators, without the need to build its own 4G / 5G / 6G network. The implementation differs from other European countries, where a separate radio network is being built for the system.

– Proxion’s measurement services are able to provide high-quality information for the use of the Digirata project in order to ensure the adequacy of public operators’ telecommunications networks throughout geographically wide Finland, Kolehmainen continues. The measurement system developed by Proxion is a comprehensive solution that is especially suitable for measuring the communication and radio networks of critical systems and for testing components.
