Asia's largest and China's first maritime 'smart highway” 5G coverage, located in Ningbo, Zhejiang

Thanks to netizen Douhuangshengfo for submitting the clue! According to official news from China Unicom on January 12, the first phase of the Ningbo section of the Hangzhou-Ningbo Expressway, Asia’s largest maritime high-speed interconnection hub, is about to open to traffic, achieving China Unicom’s 5G coverage across the entire line.

It is learned that the eastern section of the first phase of the Ningbo section of the Hangzhou-Ningbo Expressway is about 40.156 kilometers long, connecting the Jintang Bridge of the Ningbo-Zhou Expressway and the southern connection of the Hangzhou Bay Bridge respectively. As a maritime interchange overpass connected to the Ningbo-Zhou Expressway, the maritime interchange occupies 613 acres of sea area and is shaped like a clover leaf. It is currently the largest maritime interchange hub in Asia. After the completion of the first phase of the Ningbo Section of the Hangzhou-Ningbo Expressway Double Line, it will greatly shorten the time and space distance between the southern wing of the Yangtze River Delta and Shanghai, Jiangsu and other provinces and cities. In response to the special scenario of cross-sea expressways, China Unicom Ningbo has customized an optical cable double-loop protection solution for the maritime high-speed interconnection hub and the Ningbo section of the Hangzhou-Ningbo Expressway multiplex line. Special selection and installation methods are selected to ensure project quality. At the same time, with the assistance of the Tower Company, large-scale special operation vehicles were introduced to transport construction personnel and tools and instruments to the bottom of the bridge for optical cable laying. A total of approximately 28 kilometers of transmission optical cables were laid. Through the newly built optical transmission channel, The data of the 13 newly built base stations along the line are uplinked to Ningbo China Unicom's intelligent metropolitan area network, fully ensuring that China Unicom's 5G will always operate at high quality. After the completion of the construction, Ningbo China Unicom's network optimization technicians also conducted multiple rounds of field tests along the Ningbo section of the Hangzhou-Ningbo Double Line, and optimized and adjusted the relevant land base stations and 13 offshore base stations to achieve optimal 5G signal coverage. , the fastest network speed. Recently, 13 base stations newly built by Ningbo China Unicom at sea were connected to the grid and put into official use.
