Korea Rail Network Authority (KRNA) has selected Nokia as a supplier what is claimed to be the world's first LTE-R mobile broadband network. The network will be deployed on a railway line between Wonju and Gangneung as part of preparations for the 2018Winter Olympics in PyeongChang.
KRNA is responsible for the development and maintenance of railway infrastructure in South Korea, as well as a number of other countries. The LTE-R network will be used to support railway operations and employee services.
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.
The project is intended to serve as a model for future LTE-R deployments, and help further define LTE-R standardisation efforts, which are still some way off being agreed and specifications written.
For this project, Nokia will supply radio access network (RAN) base stations (eNodeBs) along with Nokia NetAct(TM), the first major virtualised network management software for mobile networks. NetAct delivers best-in-class applications for the railway operations and employee services management of KRNA.
It also delivers advanced assurance capabilities as part of Nokia's multi-domain Service Assurance programme, which provides closed-loop automation to drive greater network agility and optimisation. Nokia said its systems integration and deployment services will help to establish the new LTE-R network.
Andrew Cope, head of Korea at Nokia, said: "South Korea has been a world leader in the use of mobile broadband technology to make public services of all kinds safer, more efficient and reliable. With a thirty-year history in the delivery of GSM-R mobile networking technology for railways, and as a pioneer in the development of LTE-R solutions, we are pleased to partner with KRNA to bring these cutting edge capabilities to the country as they prepare to host one of the world's premier sporting events."
