Samsung Electronics and KDDI are wasting no time adapting 5G to trains in Japan. The two just completed a test using 28 GHz to transmit 4K ultrahigh-definition (UHD) surveillance video on a train platform in Tokyo.

The demonstration was conducted between Nov. 21 and Dec. 21 at the Haneda Airport International Terminal in Ota, Tokyo. Along with Waseda University, Keihin Corporation and Advanced Telecommunications Research Institute International (ATR), Samsung said it was able to demonstrate effective communications through 4K UHD video using a 5G base station.

It’s certainly not the first time these two have conducted 5G demos on trains. Last year, KDDI and Samsung showed how they were able to download an 8K video via the CPE installed onboard a moving train.

This latest feat demonstrates how 5G can be used to increase train passenger safety. The companies say that collecting and analyzing 4K UHD videos in real time will remove some of the burdens from the staff in charge of constantly monitoring footage. It also helps them in detecting dangers in advance and improving overall safety.

During the demonstration, the video files collected from both 4K security cameras and security robots patrolling the station were sent via tablets using 5G, according to a press release. The files were then received by the base station to be displayed on the monitor and virtual reality (VR) goggles in the monitoring room. Detecting any suspicious people or objects at the station was made possible through collecting and analyzing the received 4K files shown on the server.

The demo used Samsung’s 5G solution, and KDDI was responsible for assessing and designing the 5G test environment at the train station, which was provided by Keikyu. Waseda University provided the monitoring system, VR goggles and video evaluation.

Separately, another 5G demo involving KDDI and Samsung was conducted at an elementary school, where they compared the differences between 5G tablets and Wi-Fi tablets in their ability to download and play back videos.

A gym at Maehara Elementary School in Tokyo was set up with Samsung’s 5G network at 28 GHz to enable UHD videos. They also worked with the ATR.

The students were given a chance to create their own videos and experience high-speed and large capacity transmission of large video files. At the same time, they verified the capabilities of 5G for this type of use case. KDDI was responsible for assessing and designing the 5G areas used in the trial, and ATR provided the testing infrastructure.
