ZTE Corporation announced that it has provided a comprehensive solution for customized 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.ZTE and 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.

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.

The first “Super infrastructure” integrated with a bridge, tunnel, and artificial island

After eight years of consecutive construction and investment of over RMB 100 billion, the 55-kilometer HongKong-Zhuhai-Macao Bridge is the first “Super infrastructure” integrated with a bridge, tunnel, and artificial island. Nevertheless, the bridge belongs to special linear coverage scenarios and is located on the South Coast of China where typhoons, thunderstorms, 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 the future.

In addition, ZTE customized the fastened component in case of extreme weather. 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 10 kilometers. ZTE adopted a “two-directional single core” solution, thereby saving 75% of the fiber core.

In terms of solution verification, ZTE creatively proposed employing 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. ZTE and China Mobile
