Shenzhen Metro trials 5G service

Shenzhen Metro has piloted the world’s first subway 5G ultra-wideband wireless communication service. 

Deployed on Line 11, the network is being used primarily to improve operations. As explained on the Metro WeChat account, the subway can now transmit train data to the stations, the depot and other facilities during high-speed operations. Previously the data had to be transferred manually because packets were usually too big. Each compartment is equipped with multiple cameras and requires large bandwidth for transmission. Now, real-time monitoring allows for better management and response times. This is particularly helpful when wear and tear might cause safety issues, or in emergency situations with passengers. 

Future trials will include introducing new services for passengers.
