According to the information, China Unicom and Huawei have commercialized MetaAAU at over 1,000 sites, forming the world’s largest commercial MetaAAU network.
By deploying 3.5G MetaAAU contiguously, the continuous coverage of the bio-industrial park in Jiangxia District, Wuhan has been achieved. At the same time, SUL super uplink was opened, which was successfully applied to enterprise video surveillance services and personal HD live broadcast services. After the super uplink is opened, the 5G uplink peak value reaches 460Mbps, and the indoor remote point rate can be up to 4 times higher than before the opening, which brings an exponential increase in downlink traffic.

MetaAAU is the third-generation AAU developed by Huawei. It adopts a new architecture — an extreme-large antenna array (ELAA) — which doubles the array scale compared with the previous-generation AAU.
In July this year, China Unicom Beijing deployed MetaAAUs at over 1,000 sites in towns and rural areas such as Shunyi, Huairou, and Pinggu districts and successfully put them into commercial use. They bring 40% wider coverage area, 10% higher uplink and downlink user-perceived rates, and 5% lower network energy consumption over previous-generation AAUs, achieving optimal network performance and energy efficiency.
Ritchie Peng, President of Huawei 5G Product Line, said, “MetaAAU is one of our major innovative products in 2021. With MetaAAU, we achieve great breakthroughs in network performance and energy efficiency, and this is attributed to our strong investment and continuous innovation in Massive MIMO. We are glad to cooperate with China Unicom Beijing on the thousand-site MetaAAU project, and proud to see that MetaAAU achieves the desired performance across the entire network. We believe this can provide a useful reference for global operators in selecting Massive MIMO technologies for different scenarios.”
The combination of MetaAAU and super uplink can help the county to achieve the effect of high-quality network coverage in urban areas, meet the needs of industrial parks for large uplink bandwidth, provide network guarantee for the promotion of “5G + Industrial Internet”, and also provide network construction for county, township and agricultural hotspot areas. valid reference.
