Phoenix New Media Technology News September 27th news, in China (Beijing) International Information and Communications Exhibition, Huawei Wireless Product Line President Yang Chaobin released the Massive MIMO innovative product MetaAAU. It is reported that MetaAAU introduces ultra-large-scale antenna array technology to achieve both performance and energy saving through algorithm, architecture, software and hardware innovation. Compared with the traditional scheme, MetaAAU can improve 30% uplink coverage and 30% downlink coverage at the same time, and the average experience of edge users can be improved by 25%. When the cell edge coverage index is unchanged, the base station can be configured with lower transmission power, thus reducing the base station energy consumption, which is about 30% lower than the traditional AAU.

Since the commercial use of 5G, if large bandwidth combined with Massive MIMO technology has brought a 10-fold improvement to consumers' experience. On the one hand, consumers use more mobile networks to access the Internet, and mobile network traffic increases exponentially, and it is expected that mobile networks will carry more than half of Internet traffic in 2030; on the other hand, with the popularity of services such as short videos and live streaming, rural digital economy is developing, rural network traffic is growing rapidly, and rural mobile network traffic is growing faster than urban traffic.

Yang Chaobin said: "if large bandwidth combined with Massive MIMO technology can effectively increase cell capacity, cope with traffic growth, and reduce network bit costs, which is the basis for building the best 5G network in China. "the coverage capability of the middle frequency band is weaker than that of the low frequency band, and the traditional way to improve the base station coverage is to increase the radio frequency transmission power, but this can only enhance the downlink coverage and cannot break the uplink coverage limit; increasing the transmission power will also lead to an increase in module energy consumption, which contradicts the green energy saving goal.
