After the opening of the Beijing-Zhangjia high-speed railway, it will not only ensure the smooth holding of the 2022 Winter Olympics, but also promote Beijing's technological, financial and talent advantages and Zhangjiakou's excellent environmental resources and tourism resources to complement each other and promote high speed and high efficiency. The joint development of Beijing and Zhang.
The Hebei section of the Beijing-Zhangjia high-speed railway has a total length of 156 kilometers and 11 tunnels (48 kilometers), of which the main line is adopted.Huawei4/5G common mode 8T8R equipment, the tunnel part adopts Huawei 4/5G common mode FAD-2T2R equipment. Huawei's 4/5G common-mode high-speed rail equipment adopts Huawei's self-developed technology to provide chip-level security. The front-end interface uses 25GE optical ports. Once hardware construction, it can support long-term evolution of 5G capabilities. Huawei's high-speed rail 4/5G common mode equipment reduces a set of 4G equipment, greatly reducing the tower rent and construction difficulty. The world's first support for 12 community mergers, the number of high-speed rail user switching is reduced by 90%, effectively improving user perception. In addition, based on the fact that the current 4G service is still the mainstream business, Huawei's high-speed rail 4/5G common mode equipment not only greatly reduces the tower rent and construction difficulty, but also supports 4/5G dynamic spectrum adjustment to maximize user experience and spectrum efficiency.
Hebei Mobile opened its first 5G base station in Hebei in October 2017, and launched a series of 5G vertical industry applications in the country. By 2019, Hebei Mobile was determined to remain the leader of the 5G innovation. In March 2019, it took the lead in researching the high-speed rail 5G private network coverage program in July, and opened the country's first high-speed rail 5G telephone in July.
