Huawei Commercially Verifies the World's First Sub-1 GHz Massive MIMO

Huawei has recently announced the successful commercial verification of its sub-1 GHz Massive MIMO technology, which operates on the 700 MHz, 800 MHz, and 900 MHz frequency bands. This development marks a significant improvement in mobile network efficiency, with the new system offering five times the downlink capacity, 8 dB better uplink coverage, and four times faster uplink speeds compared to traditional low-band equipment.

The innovation lies in combining large antenna arrays with wideband technology in the low-band spectrum. This approach allows for better use of fragmented spectrum resources and enhances the overall spectral efficiency. The result is not only wider network coverage but also a more consistent 20 Mbps uplink speed, which is especially beneficial for mobile AI applications.

Additionally, the technology is compatible with existing mobile networks like GSM, UMTS, LTE, NR, and NB-IoT, facilitating smoother transitions to 5G. To address previous challenges in Massive MIMO equipment, Huawei has also focused on reducing size and weight by using new materials and designs.

According to Fang Xiang, Vice President of Huawei’s Wireless Network Product Line, this verification shows the practical value of sub-1 GHz Massive MIMO in improving network performance. The technology is expected to enhance spectral efficiency, reduce latency, and support the growing demand for mobile AI and IoT applications. As it is deployed more widely, it could help expand mobile network capabilities and improve user experiences.

In short, this technology represents a step forward in mobile network development, offering improved speed, coverage, and efficiency, while supporting the ongoing evolution toward 5G.
