ZTE teams with China Mobile in bringing excellent wireless coverage with world's longest sea-crossing bridge


Johannesburg, 26 Oct 2018

ZTE South Africa has revealed that ZTE Corporation, a major international provider of telecommunications, enterprise and consumer technology solutions for the mobile Internet, announced it has provided a comprehensive solution for customised wireless network coverage for the world's longest sea-crossing bridge, Hong Kong-Zhuhai-Macao Bridge (HZMB), in partnership with the Guangdong arm of China Mobile.

The mobile 4G download and upload rate reach 50Mbps and up to 18Mbps respectively at a high-speed scene, recording the world's advanced level.

After eight years' consecutive construction and investment of over RMB 100 billion the 55km HongKong-Zhuhai-Macao Bridge is the first "super infrastructure" integrated with bridge, tunnel and artificial island. Nevertheless, the bridge belongs to special linear coverage scenarios, and is located in the South Coast of China where typhoon, thunderstorm, high temperatures and other extreme weather regularly rage in this region.

In respect to the equipment model, the project adopts ZTE's TDD LTE multi-mode RRU and FDD LTE high-power RRU for the purpose of supporting varied modes of network coverage while addressing the storage enhancement resulting from eMBB in future.

In addition, ZTE customised the fastened component in case of extreme weathers. All the components are specially treated to protect equipment from high humidity and salinity.

To address the linear coverage scenario of HZMB, ZTE located the equipment rooms on the Zhuhai-Macao Artificial Island and West Artificial Island beside the bridge, extending the range of RRU to over 10km. ZTE adopted a "two-directional single core" solution, thereby saving 75% of fibre core.

In terms of solution verification, ZTE creatively proposed to employ the crane on the land to carry RRU in order to conduct an efficient field trial on the bridge.

By means of 5G-ready and cloud RAN solutions, ZTE's network enables GSM/FDD/NB/TDD multi-mode, multi-band integration and deployment while adopting the architecture of shared MEC and CU server for future 5G.

More than 100 experts from ZTE spent 43 months in total bringing the world's longest sea-crossing bridge with comprehensive wireless coverage, satisfying the requirements of GSM, TDD-LTE, international roaming FDD-LTE, NB-IOT and future 5G.
