Huawei develops 5G Indoor Distributed Massive MIMO for China Unicom

Huawei has developed a 5G Indoor Distributed Massive MIMO solution for China Unicom Beijing’s “5G Capital” initiative.

The 5G Indoor Distributed Massive MIMO solution is based on Huawei’s 5G LampSite Digital Indoor System (DIS). It introduces the Massive MIMO technology to LampSite to form distributed Massive MIMO antenna arrays supporting up to 64T64R ability. Through dynamic coordination among multiple digital indoor headends, the capacity on indoor networks becomes scalable, self-adapting to changes in data traffic. In addition, compared with the cell splitting approach, both interference and manual commissioning costs are significantly reduced, while also effectively increasing 5G indoor spectral efficiency.

In the first year of 5G commercial deployment, China Unicom has successfully deployed 5G digital indoor systems in key scenarios across China’s major cities.

Ritchie Peng, CMO of Huawei’s Wireless Network Product Line, said: “Based on our long-term investment in indoor digitalization region, we released the full-scenario 5G DIS product and solutions in February 2020 to enable better indoor coverage and superior 5G networks. Faced with growing scalability demand for uplink and downlink capacity, we successfully introduced Massive MIMO technology to indoor networks in close collaboration with China Unicom. This technological breakthrough will substantially increase 5G capacity. We will continue to make technological innovations and develop leading solutions that address the exact requirements of customers.”
