"the construction and reconstruction of the public network coverage of high-speed railways has always been a difficult and important part of the construction of communication facilities," said a relevant person in charge of hunan mobile. the full coverage project of the hunan section of the shanghai-kunming high-speed railway involves 144 tunnels with a total mileage of 209 kilometers, spanning changsha, zhuzhou, xiangtan and other cities. the entire project requires the installation and commissioning of as many as 731 5g main devices, which not only tests the construction team's construction technology, but also demonstrates hunan mobile's determination and strength in network construction.

the 5g signal full coverage project faced many challenges. due to the wind pressure of high-speed trains, the installation and maintenance of equipment in the tunnel chamber requires extremely high safety and technical requirements. to this end, hunan mobile has formulated a thorough construction plan and strictly abided by the regulations for the construction of the "skylight point" operating line. before and after each entry, all tools and materials will be counted to ensure that no screws are lost in the tunnel and no half-cut steel strips are forgotten, providing a solid guarantee for the safe operation of the high-speed rail line.

after nearly eight months of hard work, the construction and renovation project was finally completed on august 20. this not only provides more convenient communication services for local residents, but also sets a new milestone for hunan mobile in 5g network construction. "passengers can now use their mobile phones more smoothly to make calls, surf the internet, download videos, and other operations, without worrying about dropped calls or network freezes. even remote video conversations can easily achieve ultra-clear real-time picture quality sharing." the relevant person in charge of hunan mobile introduced that hunan mobile will continue to be committed to creating more network products, strive to provide users with better communication service experience, and contribute more to the construction of a digital, networked, and intelligent society.
