The communications network will be based on LTE-R technology, a version of 4G LTE technology that is being developed to meet the mission-critical service requirements of railway operators, and the network will support both operational and maintenance service on the high-speed line. KRNA’s LTE-R network aims to provide secure, reliable, high-speed connectivity between trains, stations and other railway facilities on the 120km line between Wonju and Gangneung. Nokia will supply radio access network (RAN) base stations (eNodeBs) along with Nokia NetAct, the first major virtualised network management software for mobile networks.
