LTE for Railways: Impact on Performance of ETCS Railway Signaling

Due to its shortcomings, in terms of capacity and data transmission capabilities, the Global System for Mobile Communications-Railways (GSM-R) is moving into obsolescence and becoming the element which limits the number of trains running in areas, such as major train stations, with high train concentration. Furthermore, advanced data services cannot be supported by GSM-R. As a result, long-term evolution (LTE), along with other modern technologies, needs to be evaluated as a potential replacement for GSM-R in terms of railway communication technologies in the future. The characteristics of the LTE railway radio access network is analyzed in this article in terms of eNodeB transmission power and eNodeB (LTE base station) density. Regarding the achieved transfer delay and data integrity of European Train Control System (ETCS) messages, a set of computer-based simulation scenarios (e.g., OPNET) with varying numbers of eNodeBs is evaluated based on this analysis.
