DAEJEON, Feb. 16 (Korea Bizwire) — The Electronics and Telecommunications Research Institute announced on Wednesday that it had succeeded in demonstrating an ultra-high speed 5G mobile communications service on a normally operating bus, offering speeds about seven times faster than existing services.
To upgrade the quality and speed of bus WiFi, the research team developed mobile network technology connecting buses with ground base stations using a 5G millimeter wave frequency with a 22-gigahertz (GHz) bandwidth.
The ETRI also developed and demonstrated mobile relay technology that enables communication through other vehicles from a base station outside of the range of millimeter waves.
The demonstration confirmed the effectiveness of the WiFi service on a normally operating bus, and offered those present the chance to experience 4K video streaming service with augmented reality (AR) glasses.
The research team confirmed a WiFi speed of more than 700 megabits per second (Mbps) in an actual operational environment, about seven times faster than current bus WiFi speeds.
The research team also identified that the streaming of 4K video stored on a communications server operated smoothly through AR glasses.
