Has Xicheng high-speed railway achieved full coverage of 4G signals?

It is reported that on June 6, 65438, the first high-speed railway crossing the Qinling Mountains in China-Xicheng High-speed Railway will be opened for operation. Xicheng High-speed Railway is the first high-speed railway in China to cross the Qinling Mountains, with a bridge-tunnel ratio close to 94%. Trains crossing the Qinling Mountains have to cross a high slope of 25/ 1000.

According to the report, data show that CRH3A new EMU "golden eye" is the main model of Xicheng Line. In addition to the core technology of Fuxing, it also adds a unique braking function-ramp braking, which has the characteristics of fast start-stop, fast ride and fast descent, and meets the parking and starting requirements of Xicheng high-speed railway on long ramps.

When designing the Xicheng high-speed railway, several mobile operators laid leaky cables to replace the base stations in the tunnel. The laying height is flush with the window, with its own signal and full coverage of 2G, 3G and 4G. Xicheng high-speed railway is also the first mountain high-speed railway with full coverage of 4G signal equipment in China.

Netizens have said that there is no need to worry that the tunnel mobile phone can't get online in the future.
