 The longest open-sea fixed link on Earth, the Hong Kong-Zhuhai-Macau Bridge (HZMB) will deploy 5G technology and the BeiDou satellite system to "constantly monitor" the safety of the bridge, according to media reports, following an incident in South China last week which saw another bridge shake in the wind. 

The deployment of the novel technologies is said to have been undertaken by China Mobile's Guangdong branch together with the administrator of the bridge, according to a report by southcn.com. 

Local administrators are set to use the low-latency 5G network in combination with the BeiDou system to provide "simultaneous, safe and highly accurate" monitoring on the bridge's condition, as well as the patrolling robots. It will be a safety contingency plan for the bridge. 

HZMB is a key transportation link in the Pearl River Delta in China. Opened in 2018, the bridge is now the world's largest open-sea fixed link, connecting China's Hong Kong and Macau special administrative regions and the city of Zhuhai in South China's Guangdong Province. 

The announcement came after an incident in Guangzhou, Guangdong Province last week which saw China's first large suspension bridge - Humen Bridge - visibly shake in the wind, leading to worries the bridge would collapse. 

Guangdong is one of the most fast-paced provinces in China in terms of 5G deployment. By the end of 2019, the province had set up 36,988 5G base stations, and is expected to reach 50,000 stations by the third quarter of 2020, according to a report from the Xinhua News Agency.
