China Mobile Shanghai has officially started 5G network construction at Hongqiao Railway Station in Shanghai, which is expected to be the world’s first railway station equipped with a 5G digital indoor system, The Paper reported.

It is hoped to complete the depth coverage of the 5G network in 2019.

The 5G DIS technology can achieve a network peak rate of 1.2 Gbps. This means that after logging in to the network supported by DIS, it takes less than 20 seconds to download a 2GB HD movie.

Meanwhile, the station can control the flow of people more accurately and invest more robots to provide more intelligent services including food delivery and indoor navigation.

The instalment of 5G DIS is very simple — the gadget hangs on the ceiling like a light, and it only needs to be screwed down like changing a lightbulb.

The radius of a 5G DIS is 25 to 30 meters, so the entire Hongqiao Railway Station requires just 1,000 DIS devices.
