As such, China Unicom Beijing and Huawei unveiled a 5G indoor ubiquitous Gigabit network in the National Stadium, as a part of the joint 5G Capital initiative between them. This announcement came during the commemoration of the 2021 World Telecommunication & Information Society Day (WTISD).
The Massive MIMO technology of Huawei is the widely improved gigabit network technology that delivers enhanced signal quality, assures high-speed transmission, and a high-quality experience in dense areas covered with 5G. It allows indoor networks to grasp the multi-user MIMO (MU-MIMO).
Combining the 5G LampSite digital indoor network products that support an ultra-wide bandwidth of 300 MHz and the innovative distributed Massive MIMO technology, the network delivers a perceived data rate of above 1 Gbps in 90 percent of the grandstand area.
Both the firm used the combined techniques of a 5G LampSite digital indoor network with an ultra-wide bandwidth of 300 MHz and the innovative distributed Massive MIMO technology.
Benefits of MIMO
Distributed Massive MIMO is vital to greatly improve 5G performance and support 5G indoor ubiquitous Gigabit networks. Incorporating the leading technologies of outdoor 5G Massive MIMO into indoor networks, distributed Massive MIMO provides indoor networks with joint beamforming and multi-user MIMO (MU-MIMO) to enhance both the 5G network capacity and user experience.
Also, it improves signal quality by eliminating the co-channel interference on multi-cell networks to provide a high-speed and high-quality experience in most areas with 5G coverage. The field results showed an improvement of over 30 percent in user-perceived speed and consistent Gigabit experience for users on the move.
Many fellow companies of Huawei are benefited by this high-performance network technology and the company is still expanding its reaching areas.
Yang Peng, Deputy General Manager of China Unicom Beijing’s Network Division, said: “By jointly initiating the 5G Capital initiative with Huawei, we aim to build ubiquitous high-quality 5G networks. With the deployment of the 300-MHz LampSite pRRUs and distributed Massive MIMO in the National Stadium, China Unicom Beijing can now provide the ultra-large network capacity required to provide the audience with immersive experience while preparing networks for smart applications such as AR with ubiquitous Gigabit connections.”
This stadium is spread over 258,000 m2 with that 91,000-sitting capacity. It is also famous as Bird’s Nest and indeed of ubiquitous high-speed experience for the high density of mobile users present during the events.
Marvin Chen, President of Huawei DIS Product Line, said: “Distributed Massive MIMO introduces Massive MIMO to the digital headends of indoor networks. Due to this innovative application, up to 64T64R transmission is now possible in indoor networks, adding to new tools carriers can leverage to provide ubiquitous Gigabit experience in indoor areas. Huawei will continue to innovate network solutions to help carriers achieve ToB and ToC success.”
