Abstract
Railway environments cannot be away from the current evolution of public
communication systems. The Long Term Evolution (LTE) mobile
communication system is considered to be the natural evolution for current
Global System for Mobile Communications Railways (GSM-R). LTE all IP
networking technology plays a key role for the integration and convergence of
heterogeneous networks and services, both the specific for the railway operative
and the commercial broadband ones for passengers. The adoption of a new
generation standard for railway communication must be based on an exhaustive
feasibility study of the new system to become the railway mobile communication
system. In this paper, LTE’s top challenges to address the specific requirements
and features of railway communication services are evaluated. Under this scope,
LTE features to implement the required railway functionalities, LTE technical
challenges, spectrum harmonization, network deployment considerations and
LTE capabilities to meet the railway service Reliability, Availability,
Maintainability and Safety (RAMS) requirements, are assessed.
Keywords: LTE, high speed railway, VoLTE, LTE features, RAMS, challenge
