Samsung and provider KDDI achieved a peak download speed of 1.7 Gbit/s on a 5g connection test performed in a moving train, in Japan. The researchers of the companies managed to download an 8k video file and upload 4k video while doing so.
This was achieved along a section of track where the distance between two stations was approximately 1.5km (nearly 1 mile). During the demonstration, the companies achieved a successful downlink and uplink handover as well as a peak speed of 1.7 Gbps.
The tests were carried out from October 17th through the 19th in the city of Saitama in Japan, near Tokyo. 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 (5G Radio), virtualized RAN and virtualized core. The demonstration leveraged capabilities driven by 5G, such as high throughput, low latency and massive connections, which verified potential services and use cases that would be highly-beneficial to passengers and operators of high-speed trains. This could pave the way to vastly improved backhaul for onboard WiFi, superior passenger infotainment and increased security and analytics
In addition to a successful downlink and uplink handover at more than 100km/hour (over 60 mph), 8K video was downloaded via the CPE installed on-board, and a 4K video filmed on a camera mounted on the train was able to be uploaded.
