Recently, a reporter from Jimu News learned from China Mobile Hubei Company that with the official completion of the entire tunnel of Wuhan Metro Line 19, Hubei Mobile has now completed 5G network coverage from Xinyuexi Park to Gujiashan Station, and full coverage of the 5G private network in the rail area , and successfully conducted test runs, Line 19 became the first smart urban rail line in China to achieve full 5G private network coverage.

It is understood that Wuhan Rail Transit Line 19 starts from West Square Station of Wuhan Railway Station and ends at Xinyuexi Park Station. The fastest subway. In order to effectively support the construction of 5G smart urban rail and build a large-bandwidth and highly reliable digital network capability, Hubei Mobile adopts an innovative 5GtoB dedicated spectrum (4.9GHz) to build a 5G dedicated network with advanced technology, low cost, and long-term business development. Network, realizing the evolution path of one-time construction and phased service launch, meeting the development needs of various types of 5G services in Wuhan Metro.
At the same time, due to the barriers of foreign technology monopoly in the traditional subway train dispatching communication standard technology, only supporting voice calls, and high operating and construction costs, Wuhan Metro Line 19 is the first to commercialize 5G broadband clusters. Follow domestic standards to realize independent innovation of intellectual property rights; meet multiple call methods such as voice and video, and promote rail transit linkage command to be more convenient and unified dispatch more efficient. After network and business commissioning, completion of test runs and other key verification links, the on-site test in the track area has an uplink rate of 101Mbps and a downlink rate of 1067Mbps.

"Relying on the 5G private network, subway staff can directly dial high-definition video calls through 5G cluster terminals. The whole video screen is clear without jitter, and the voice is smooth without stuttering; it also supports connection to conference systems, video management and other platforms to achieve multi-party integrated communication. According to the person in charge of Hubei Mobile, Line 19 is the first time in the industry to use a 4.9G private network to complete the deployment of the entire line, realizing the first new first-tier city line network level urban rail cloud construction in the country, breaking the "data island" and smooth business data interconnection and sharing , to help Wuhan Metro create a new model of smart urban rail with reliable operation and maintenance, comprehensive perception, and intelligent scheduling.
In response to the tidal effect of rail transit, the number of connected users and traffic demand for subway morning and evening peak communication services will increase sharply, which will bring greater impact and challenges to 5G networks. According to the track construction progress of Wuhan Metro Line 19, Hubei Mobile surveyed the tunnel on the spot. It took 45 days to successfully install 110 AAUs (active antenna units), 56 fiber distribution boxes and special communication equipment rooms, and completed the 150-kilometer tunnel. Laying of optical cables, deployment, commissioning and commissioning of 5G cluster systems will lay a solid foundation for the communication network for the construction of 5G smart urban rail.

In 2019, Hubei was selected as one of the first batch of pilot projects for the construction of a strong transportation country, and the development of smart urban rail construction is an important part of the pilot project for a strong transportation country in Hubei. In order to promote the implementation of 5G smart urban rail, Hubei Mobile and Wuhan Metro will establish a 5G smart urban rail joint innovation laboratory in 2020, and implement 5G full coverage of all opened lines in accordance with the progress of subway construction, helping Wuhan rail transit to fully enter the 5G era.
In the future, Hubei Mobile will accelerate the deep integration of 5G, cloud computing, artificial intelligence and other technologies with rail transit, comprehensively improve the informatization, digitalization, and intelligence level of the rail transit industry, and help Hubei build a demonstration zone of a transportation power.
