Nokia has been selected by the Korea Rail Network Authority (KRNA) as a supplier for the LTE-R mobile broadband network to support railway operations and employee services. The network will be deployed on a railway line between Wonju and Gangneung as part of preparations for the major international sporting event being hosted by the country in 2018. KRNA is responsible for the development and maintenance of railway infrastructure in South Korea as well as a number of other countries.

The communications network for KRNA 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. The network will support both operational and maintenance services on a high-speed commercial railway line operating at speeds of up to 250 km/h.

KRNA's LTE-R network will provide secure, reliable, high-speed connectivity between trains, stations and other railway facilities between Wonju and Gangneung. The network will also be designed to interoperate with other LTE networks supporting public safety and maritime operations as well as legacy VHS (very high frequency) and TRS (trunked radio system) radio networks. This project is intended to serve as a model for future LTE-R deployments, and help further define LTE-R standardization efforts.

For this project, Nokia will supply radio access network (RAN) base stations (eNodeBs) along with Nokia NetAct(TM).
