Abstract
Development of high-speed railways set up challenges for new communication technologies. With the increase in speed, new requirements for communication systems have emerged that HSR requires greater reliability, capacity and shorter response time for efficient and safe operations. Mobile communication systems are crucial for the competitiveness of the railway industry and therefore have become one of the priorities addressed by the participants in the railway system to take advantage of technological opportunities to improve operational processes and the quality of provided transport services. The European Rail Traffic Management System (ERTMS) uses the Global System for Mobile Communications for Railways (GSM-R) for voice and data communication to communicate between trains and control centers. The International Railway Union is exploring new ways of communicating for high-speed railways because as speed increases this system becomes unreliable in information transmission. This paperwork presents an analysis of the evolution of communications on European railways since the usage of GSM-R. In addition, an overview of the various alternative solutions proposed during the time (LTE-R, Future Railway Mobile Communication System) as possible successors to GSM-R technology is given.
Highlights
Communication technologies have always played a key role in the railway system due to its size, long distances, large number of employees and passengers, and constant mobility
It is based on Global System for Mobile Communications (GSM) mobile phone network standards but uses other carrier frequencies designated for rail traffic and there are several additional functions adjusted to rail traffic
For the Global System for Mobile Communications for Railways (GSM-R) new digital radio standard for European railways, specifications have been developed in the Union Internationale des Chemins de Fer (UIC) project EIRENE (European Integrated Railway Radio Enhanced Network) which defines the requirements that railway radio communication systems must meet in order to ensure interoperability between national railways
Summary
Communication technologies have always played a key role in the railway system due to its size, long distances, large number of employees and passengers, and constant mobility. GSM-R (Global System for Mobile communications Railway) is the first international mobile communication system developed for the requirements of railways It is based on GSM mobile phone network standards but uses other carrier frequencies designated for rail traffic and there are several additional functions adjusted to rail traffic. These additional functions provide the possibility of voice communication between the train operator and the control/monitoring centers of the railway traffic, as well as the transmission of the maximum permitted speeds in certain sections to the control cabin of the train. With the era of the 5G mobile network, 5G-based rail communication technology will become a trend and a key generation for rail-mobile communication technology
