China Telecom and Huawei have completed the rollout of ‘hundreds’ of 5G C-Band Book Radio Relay Units (RRUs) in Shenzhen, providing ‘significant improvements’ to in-depth coverage and user experience in residential areas, the two companies announced in a joint statement. The lightweight Book RRUs enable rapid 5G deployment, the two companies explained, by utilising walls and utility poles as sites, reducing existing issues with rollouts in residential areas, where insufficient resources and site acquisition can be costly and time-consuming. The technology, which supplements macro-site base stations, also allows providers to deploy 5G quickly, patch-up holes in coverage and offload network traffic.
Huawei and China Telecom’s Shenzhen unit tested the technology in December 2019 using 4T4R 5G Book RRUs, achieving peak downlink speeds of 1.2Gbps on commercial mobile devices and using 100MHz of network spectrum. The deployment has allowed the cellco to meet capacity requirements in ‘value hotspots’ in the city, such as school campuses, office buildings and scenic parks.
