KDDI and Samsung Hit 1.7 Gbps on a Speeding 100 Km/hour Train in Latest 5G Demo

KDDI and Samsung Electronics have successfully completed the first 5G demonstration on a moving train traveling at over 100 km/hour (over 60 mph). 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 100 km/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.

"In collaboration with Samsung, KDDI has opened up the possibility for new 5G vertical business models, such as a high-speed train. 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," said Yoshiaki Uchida, Senior Managing Executive Officer at KDDI. "To fulfill our aim to launch 5G by 2020, KDDI will continue exploring real-life scenario experiments for diverse 5G use and business cases together with Samsung."

"The potentials that 5G holds is powerful enough to transform the landscape of our daily lives," said Youngky Kim, President and Head of Networks Business at Samsung Electronics. "The success of today's demonstration is a result of our joint research with KDDI, which we will continue to pursue as we explore next generation networks and use cases This will include research on diverse spectrums and technologies, as well as new business models and applications."

Since 2015, KDDI and Samsung Electronics have been closely collaborating to demonstrate 5G millimeter wave performance in various scenarios. This includes a multi-cell handover demonstration that took place in February, where the device was mounted on a car that traveled in the busy streets of Tokyo, and a high-speed mobility test with the device attached on a car racing at 200 km/h in Yongin, Korea in September.

Let 4G catch on in terms of speed, also data caps? This is just another excuse for the govt to charge for a new set of airwaves & of course telecom operators/manufacturers to sell their overpriced devices/services in the name of innovation!

Whit phone like this there will be no 5G
One operator in my country already has reserved 5G radio frequency.

I live in a country of paradoxes. We had commercial WiMax networks in urban areas before 3G was even a thing, we have cheap and fast fiber everywhere, yet we have a laughable 3G coverage and STILL no 4G/LTE.

what's the relevance of the train/user in motion?

why not just boast about the network speed?

Yo Dawg I heard you like high speed internet and fast trains. So we put high speed within fast speed. So you can play Densha De Go while you Densha De Go.

There are multiple factors:

- Signal strength is directly proportional to throughput/goodput

- Cell-to-cell and inter-radio handovers (IRAT) cause short outages when the end device traffic is rerouted and the device swiches networks

- Current radio technologies do not work when the velocity of the end device exceeds ~200 km/h

Downlink speed is important and easy to sell, but reliability and verstatility are key goals in 5G development.

Also, using either WiFi or a mobile network connection when traveling via train usually amounts to a bad experience and that's easy for people to identify with :D
