South Korean Firm Selects Softil Technology for LTE-R Devices
Tuesday, February 11, 2020 | Comments

South Korea’s RF-Comm selected Softil technology to build the next generation of Long Term Evolution (LTE)-Railroad (LTE-R) high-speed train communications devices for KORAIL, South Korea’s national railroad network.

The LTE-R devices will be deployed on the Daegok to Sosa KTX intercity line, the highest class of KORAIL services, and will enter service in early 2021. The deployment is consistent with South Korea’s policy that all public-service communications including trains, police and firefighting services switch to broadband technologies.

Softil’s BEEHD technology is a cross-platform client framework designed for chipset vendors, device manufacturers, system integrators, application developers and service providers to develop IP-based mission-critical voice and video communications over LTE solutions.

GSM-Railway (GSM-R) has been the standard for digital railway communications for many years. But with LTE-R-based devices offering lower latency, higher data capacity and better security than GSM-R systems, railway networks are now migrating to LTE-R communications devices for wireless voice and data communications inside trains, from the train to the ground and from train to train.

LTE-R supports voice communications among drivers, control center operators, maintenance and other railway staff supporting push-to-talk (PTT) group communications, broadcasting, location-dependent addressing and multilevel prioritization.

RF-Comm’s devices will also allow data communications for train control signaling and other operations and maintenance, as well as text messaging during voice communications. The devices will allow multimedia communications for wireless video surveillance, mobile video conference, file sharing, mobile office and passenger infotainment services.

“South Korea is now on a par with China and Japan as the world’s leading high-speed railway network, and only the finest communications equipment and devices can be used in bullet trains for stable and secure communications,” said RF-Comm CEO Dong Hyung Kim. “We chose to build RF-Comm’s new LTE-R communications devices for KORAIL using Softil’s BEEHD technology as it offers the best quality, most advanced standards-compliance and significant time-to-market advantage.”

In 2018, South Korean firm Daeyoun selected Softil technology for terminals to be used in Seoul’s subway, and solution integrator K-Won selected the firm’s technology for its LTE-R terminals.
