Huawei and China Unicom have jointly verified what they claimed to be the first 5G indoor distributed massive MIMO technology in the industry.
The technology, which integrates massive MIMO into digital indoor systems, delivers a peak rate of up to 4.7 Gbps for cells with 100 megahertz of bandwidth.
Huawei and China Unicom launched a joint innovation project dubbed “5G Capital” in Beijing. It was set up to build high-quality 5G networks for individual mobile users, and to empower digital transformation across industries through technological and experience innovation as well as the incubation of ecosystem. The indoor distributed massive MIMO technology is one of the applications implemented in the 5G Capital project. This application integrates 5G massive MIMO with LampSite – Huawei’s digital indoor distributed system – to improve the cell capacity for indoor scenarios that need to provide a premium user experience and high capacity.
Indoor distributed massive MIMO will be key in 5G smart stadium projects, bringing a premium experience concurrently to individual users while also ensuring that dedicated services continue to run smoothly, Huawei said. It was deployed and verified in the China’s National Center for the Performing Arts (NCPA). The verification test was performed using multiple terminals, and results showed that the downlink peak rate reached 4.7 Gbps in 100 MHz C-band cells. This result demonstrates that this solution fulfills the service requirements in dense indoor areas while providing a strong foundation for developing various HD video interactive services, the Chinese vendor added.
The indoor distributed massive MIMO technology will be the core of networks intended for transport hubs, large venues, and other high-density scenarios where premium user experience must be ensured, according to Huawei, and tt will also help develop new services in smart stadiums, campuses and education.
Li Fuchang, director of the Wireless Technology Research Center of China Unicom Research Institute, said, “At China Unicom, we are committed to improving the quality of products and services through innovation to bring intelligent technologies to customer’s lives and increase the efficiency of production for businesses. To achieve this goal, China Unicom has been working with Huawei to innovate on the indoor distributed massive MIMO technology. With the rapid development of user bases and applications, 5G traffic requirements will increase also rapidly. This solution will help us pursue flexible capacity expansion on live networks, laying a solid technological foundation for continuing to deliver premium 5G experience for customers and diversifying 5G vertical applications for various businesses.”
“Indoor distributed Massive MIMO is a technological leap based on long-term technological accumulation,” said Marvin Chen, president of Huawei’s DIS product line. “It will redefine the ways we expand capacity to help operators cope with traffic upsurges and meet service requirements for both individuals and enterprises. Indoor distributed massive MIMO will play a unique role in commercial networks and be a new starting point toward further technological innovation based on market requirements to provide first-class 5G indoor coverage solutions.”
