KRW 10.1 billion project, success in winning consecutive orders following mass production

[IT Daily] STraffic, a global transportation solutions company, announced on the 10th that it signed a contract with the SKT consortium to build an integrated railway wireless network (LTE-R) for Busan Urban Railway Lines 2 to 4, in Korea. The size of this contract is approximately 10.1 billion won, and the project is targeted for completion in October 2026.

This project is being carried out as part of the ‘Essential Tasks for Smart Maintenance of Railway Facilities’ selected by the Ministry of Land, Infrastructure and Transport. S-Traffic plans to improve the aging VHF and TRS train wireless communication systems being built and operated on Busan Urban Railway Lines 2 to 4 into a high-speed railway wireless communication network (LTE-based Railway Wireless Communication System (LTE-R)). The goal is to improve safe operation of urban railways and strengthen passenger services.

LTE-R is a wireless network that optimizes LTE (700 MHz frequency band), the 4th generation mobile communication technology, for the railway environment. Unlike existing VHF (Line 2) and TRS (Lines 3 and 4) communication networks that only support transmission and reception of voice and text, it also supports video and large data transmission. Quick and efficient response between engine drivers, station staff, and traffic control is possible not only in normal times but also in various disaster situations, and safety hazards can be preemptively detected during train operation.

Through this project, STraffic expects to once again prove the performance of its various solutions, including the wireless system for LTE-R train vehicles. Furthermore, it is expected that the company will be able to get ahead of its competitors in winning orders for railway integrated wireless network projects in other regions.

STraffic is securing related technologies thanks to the development of the LTE-R solution, which has been carried out as a national project by Samsung SDS and the Korea Railroad Research Institute since 2011. The business rights, including personnel involved in core solution development, were transferred from Samsung SDS and the business is being promoted. In March of this year, a contract was signed to supply on-board devices of the LTE-R system, an LTE-based railway wireless communication device, to the Wirye Line tram for the first time in Korea and abroad. In December last year, a supply contract was signed for the first phase LTE-R construction project on Seoul Line 9.

An STraffic official said, “We are actively pursuing business orders in various fields such as road, railway, and aviation in the second half of this year, and we have achieved visible results in order winning.” He added, “We will utilize our technology to build the Busan Urban Railway LTE-R in accordance with the plan. “We will complete the construction project,” he said.
