Samsung Achieves 1.7Gbit/s Downloads with 5G traveling at 100 km/h in a train
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.
“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 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 potential 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.”

I don't know if mobile data caps will change a lot once 5G reach mainstream but right now i have the best plan i know in my country and it's only 25 GB per month.
Let's to the math: 25GB=150Gb so i can "enjoy" 88.23 seconds (150 Gb/1.7Gb) of the shiny new 5G speed per month!

This is really cool and obviously a major achievement, but I also question how much this kind of technology was worth investing in. Nowadays, most people's phones have wireless broadband, and I'm sure in Asia, the phone providers aren't so stingy about bandwidth caps or tethering. In other words, seems like it's already nearing obsolescence.
