Beijing-Tianjin Intercity High Speed Rail Project

Project implementation time:October 2016 - January 2017
Project background

快3彩票Beijing-Tianjin Intercity High Speed Rail is the first high-speed railway in China with a speed of 300km/h or above. The whole journey is 120km, including 5 stations of Beijing, Yizhuang, Yongle, Wuqing and Tianjin. It opened on August 1, 2008.

快3彩票With the rapid development of the Beijing-Tianjin Intercity High Speed Rail, there is an urgent need for large bandwidth, such as passenger Internet access, video surveillance in train compartments and EMU operation monitoring. However, the railway-dedicated wireless communication system GSM-R is a narrowband system. At the same time, the train speed is getting higher and higher. It is necessary to find a wireless communication technology to meet the needs of high-speed movement, large capacity, high reliability and low latency.

Project details

In October 2016, the Beijing-Tianjin Intercity High Speed Rail EUHT system, which was designed according to the high-speed railway construction engineering standards, was implemented. It was completed and opened in January 2017. Beijing-Tianjin Intercity High Speed Rail with a total length of 120km became the world's first high-speed rail with ultra-broadband wireless communication network, which realized the passenger Internet service and HD video backhaul in carriages.

快3彩票At the speed of 300km/h of Beijing-Tianjin Intercity High Speed Rail, the third-party independent test proves that the average throughput rate of EUHT system reaches nearly 150Mbps, the handover success rate is 100%, the data packet loss rate is less than 0.41%.and the average transmission delay of uplink and downlink data is 5-6ms.

The Beijing-Tianjin Intercity High Speed Rail EUHT system has been operating stably for nearly one year, successfully carrying high-speed rail passenger Wi-Fi Internet access and high-definition video surveillance services. The latest research and development results not only exceed the foreign chips that are still imported and used by domestic high-speed rails, but also exceed ten times of the chips that will be trial-produced abroad, basically meeting the requirements of the international railway organization for 2025-2030, but more further research and development is still on the move.
