The Bus Group has also launched a “Guangzhou Traffic + Xingxuntong” guide service, providing optimal travel service for more than 8 million users. Through the 5G network, passengers can check whether the bus has seats and whether it is crowded, and can avoid crowds during the epidemic.
Leading 5G Intelligent Network-Based Driving
5G remote synchronous driving has been implemented. Through the 5G network, vehicle driving data is uploaded in real time, and HD videos are back-hauled in real time and synchronized to the instruments and meters in the remote control room for display.
First 5G Smart Road Administration Inspection
Nansha Bridge has been the world’s first extra-large bridge with full 5G coverage. The bridge has realized China’s first smart inspection of 5G road administration vehicles and 5G drones, being truly “connected, accessible, visible, and commanding”. This completely improves security and emergency rescue capabilities.
Eight New Sights of Guangzhou with 5G Dual Gigabit Networks
If 5G industrial applications are a thriving spring forest, 5G network will be the foundation of their survival. Only with the deep-rooted and well-developed 5G infrastructure network can various applications flourish in smart cities. Through the point-line-plane multi-dimensional coverage, only with a deep-rooted 5G infrastructure and a well-developed root system can there be a flourishing of various applications of Smart City. Through multi-dimensional coverage, Guangzhou Mobile and ZTE have built a 3D seamless 5G network that can easily achieve stable 5G connectivity and excellent experience.
The 5G network has brought new life to this ancient Guangzhou. The combination of leading technology and natural landscape has made possible eight new sights of Guangzhou with 5G dual gigabit networks available everywhere on bridges, in cars, and from indoor to outdoor.
Pearl River New Town
As a national central business district (CBD), Pearl River New Town of Guangzhou has the densest skyscraper complex of over 300 meters in China. To meet the coverage needs of these skyscrapers, Guangzhou Mobile and ZTE proposed an innovative 5G 3D 1+X vertical coverage solution. It has been verified that the vertical coverage can be increased by 30%, the access capacity 30%, and the service capacity 5%. Its lean beam transmission can also reduce equipment energy consumption by 10%, achieving super 5G coverage scenario.
University City, also known as South China’s Silicon Valley, is the birthplace of Guangzhou 5G, where the world’s first 5G NR is built.
