China Telecom and ZTE have tested 5G on Shanghai’s maglev (magnetic levitation) high-speed train.


They report that during the test, commercial 5G terminals were stable and able to support various high-bandwidth applications. The test measured communications within a train travelling at up to 500KM/h.

 

Shanghai Maglev is the world’s first commercial high-speed maglev line as well as the fastest commercial high-speed train in the world.

 

Shanghai Maglev is the world’s first commercial high-speed maglev line as well as the fastest commercial high-speed train in the world. Maglev technology uses two sets of magnets, one set to push the train up off the track, and another set to move the train ahead. The lack of friction and moving parts allows for higher speeds.

The rail connectivity challenge

 

Providing high-quality network coverage for high-speed trains has always been a challenge for both operators and equipment vendors. Issues include a lack of masts away from highly populated areas, as well as buildings, trees and train carriages and windows blocking or reducing mobile signals.

 

To solve these problems, ZTE and China Telecom say they have made breakthroughs in several areas, including using proprietary ’doppler frequency shift channel compensation’ technology to reduce wireless channel deterioration caused by high-speed movement.

 

To solve long-standing rail connectivity challenges, ZTE and China Telecom say they have made breakthroughs in several areas.

 

ZTE claims to be the first in the industry to use the most advanced remote radio units (RRUs), compatible with both the 2.5GHz and 3.5GHz bands, for high-speed railway coverage. It combined 8T8R multi-RRUs with 5G channels and beam-scanning technology to improve coverage.

 

ZTE and China Telecom will continue to test and verify 5G networks for high-speed rail.
