The Greater Bay Area of Guangdong, Hong Kong and Macau is one of the most open and economically dynamic regions in China. With the rapid development of urbanization, there are a large number of urban villages in Guangzhou, Shenzhen and the surrounding area, and super-high-rise residential buildings are also very common. To meet people’s entertainment needs, such as 5G HD video calls, online games and video on demand, and promote the development of production services such as e-commerce live webcasting, 5G coverage depth is urgently needed in high-rise buildings and residential areas of urban villages. However, a traditional cover solution called a “spotlight” is still used in urban residential buildings. This old solution requires a large number of routed power lines with a lot of power distribution, which increases the difficulty and cost of construction, and causes serious problems such as signal loss along the way. In addition, “spotlight” antennas cannot be monitored and are often difficult to maintain on a daily basis.
China Unicom Guangdong pays close attention to 5G coverage and experience in residential areas. Based on careful study of the actual situation in the residential area, Guangdong Unicom and Huawei came up with the innovative DRS solution. This solution makes full use of the fundamental 5G coverage of surrounding macro base stations. Then it uses a super-flexible charger to precisely deliver useful 5G signals to where it’s needed. In this way, the innovative architecture of the 5G DRS solution not only effectively prevents the leakage of useful signals along the route, but also enables the digital management and control of the entire system. On-site verification at China Unicom Guangdong showed that 5G DRS solution improves 5G uplink coverage by about 10dB compared with traditional “spotlight” antenna solution, reduces system power consumption by more by 50% and can be deployed at a maximum distance of 100 meters.
With the “U-Joy Cities” program, China Unicom Guangdong and Huawei, along with other partners in the mobile industry, will further strengthen their innovative cooperation and conduct in-depth research on tunnels, high-speed railways and block scenarios, to make 5G connection for people easier and faster, to make life in Guangdong smarter and more enjoyable.
