It is expected to be able to enjoy augmented reality (AR) service on the subway.
According to the Korea Electronics and Telecommunications Research Institute (ETRI) on the 10th, through an international joint research with the UK, it has succeeded in demonstrating AR service using mobile backhaul communication technology in the subway.
When this technology is commercialized, it is possible to smoothly enjoy various multimedia such as high-definition video streaming even in moving environments such as buses and subways.
Last month, ETRI demonstrated 5G service using an ultra-high frequency wireless backhaul system within the subway line between Jamsil Station and Songpa Station on Subway Line 8. The demonstration on this day is 1.9Gbps, which is 30 times faster than the previous one. It is about 190 people who can use AR immersive multimedia service at the same time.
Currently, the average download speed of the wireless LAN service provided by the mobile communication service provider in the subway is 58.50 Mbps, which is even lower during commute times when passengers are crowded. In such a communication environment, there is a limit for users to use large-capacity multimedia services. The researchers applied an ultra-high frequency-based wireless backhaul that connects to the Internet using an unspecified frequency band.
ETRI installed a base station system in five sections of the subway tunnel, a gateway and a server in the communication room of Jamsil Station, and a terminal system in the cab of the subway to create a communication demonstration environment.
In addition, the researchers created a system that uses a signage monitor that advertises the latest sneakers, connects a smartphone app with AR glasses, and puts on shoes with AR technology. It is expected to have a great ripple effect on the advertising market in the future.
A technology has been developed so that data is not lost even when the subway station moves and the base station connected to the terminal changes.
This research has been conducted as an international joint research with the UK since April 2019. In Korea, it developed an ultra-high frequency-based subway wireless backhaul system, and in the UK, it developed a 5G-based immersive multimedia (AR) service.
“Through this demonstration, we have confirmed that high-speed wireless LAN services can be provided in commercial public transport networks such as subways,” said Kim Myung-joon, director of ETRI. It means a lot,” he said.
British Ambassador Simon Smith also said, “The 5G technology developed by Korea-English joint research will enter the demonstration stage in the UK next month.” We look forward to a successful settlement.”
ETRI supervised this research, and the Willus Institute of Standards and Technology, Dankook University Industry-Academic Cooperation Foundation, Clever Logic, and Seoul Transportation Corporation participated as joint research institutes and commissioned research institutes. In the UK, Cisco is supervising, and Sublime, Ampoule Spot, Strathclyde University, and Glasgow City Council are participating as joint research institutes.
