Samsung Electronics has successfully completed the first 5G demonstration on a moving train, partnership with Japanese telecommunications carrier KDDI, achieving peak speeds of 1.7 Gbps as well as downlink/uplink handover.
For the tests, Samsung’s 5G pre-commercial end-to-end solution was used, which is composed of a 5G router(CPE), radio access unit, virtualized RAN and virtualized core.
The test was carried out from October 17 through the 19th in the city of Saitama in Japan, near Tokyo. The Train was traveling faster than 100km/h between two Stations in Saitama, Japan, with each station around 1.5 km away. The tests contain 8K video being downloaded by the 5G router on the board, and 4k video filmed from a camera atop the train being uploaded.
The test show how 5G could be used by high-speed train passengers, such as backhaul on the board WiFi, and for improved passengers entertainment and for information services with security and analytics built in according to Samsung.
The senior managing executive officer of KDDI Yoshiaki Uchida said, “In collaboration with Samsung, KDDI has opened up the possibility for new 5G vertical business models, such as a high-speed train”. He added, “With 5G expected to bring railway services to a whole new dimension, the success of today’s demonstration in everyday locations such as a train and a train station is an important milestone indicating 5G commercialization is near”.
He also said that KDDI focuses to release 5G by 2020, and will continue researching and trialing use cases, spectrum brands, and technologies with Samsung, which it has worked with on millimeter-wave (mmWave) 5G solutions since 2015.
Samsung has also been working with SK Telecom on 5G trials, in September declaring the first handover between 2.6GHz spectrum 4G LTE and 28GHz and 3.5GHz spectrum 5G networks.
SK Telecom and Samsung have constructed a 4G and 5G radio station with virtual core networks using various spectrums near the carrier’s headquarters in Euljiro, Seol, using the test to stream 360-degree virtual reality (VR) video from the HQ to the moving vehicle.
Samsung also tied-up with charter-communications in the United States for a series of 5G lab and field trials to evaluate the use of mmWave spectrum at the 28gHz band in September.the electronics giant is similarly collaborating with Sprint an advanced mobile networking as well as with Verizon, T-Mobile, and AT& T.
AT& T is similarly making use of Samsung’s 5G router, 5G radio frequency integrated circuit (RFIC) chipset virtualized core and vRAN in its network deployments in 20 metro areas across the US.
Samsung has also developed a 5G antenna and a power amplifier and a 5G RFIC that will be used in base stations and radio access products.
