High Speed Railway Mobile Communication System based on 4G LTE technology
Keywords:
High speed railway, LTE, GSM, communication and signaling system.Abstract
with the change in time High speed railways (HSR) requires reliability, safety train operation and passenger communication. To make it happen HSR’s system needs higher bandwidth and shorter response time, also the old technology in HSR’s needs to develop new technology, improving the existing architecture and controlling costs. To fulfill this requirements HSR’s adapt GSM-R technology which is evolution of GSM, but it fails to customer satisfaction. So the new technology LTE-R is adopted, which provides higher bandwidth as well as gives greater customer satisfaction at high speed. This paper introduces LTE-R give the comparison between GSM-R and LTE-R, also describes which technology is better at high speed in railway mobile communication system.
