But as soon as operators start to roll out 5G beyond cities, the ISD picture changes. The inter-site distance (ISD) in China and South Korea typically works out at between 300m and 600m. MetaAAU, explained Chaobin, can help industry address these pressing challenges. Extending coverage into less densely populated areas is one requirement, as is coping with more demanding user-behavior and ensuring networks are greener. Wireless network innovation is constantly needed, as operator requirements are not standing still.Ĭompared with the early days of 5G, for example, different deployment scenarios need to be catered for. “By introducing 384 antennas in the AAU, coverage can be improved by 3dB on both the downlink and the uplink, and the user experience can also be improved by 30%,” said Chaobin, “Energy savings of 30% can also be achieved.” It’s double the number of a traditional AAU. MetaAAU, developed by Huawei, incorporates ELAA (extreme large antenna array) technology supporting 384 antenna elements. Speaking at the recent Mobile Broadband Forum event in Dubai, Yang Chaobin, president of Huawei Wireless Solution, flagged numerous technology innovations and advances that take the traditional AAU (active antenna unit) found in Massive MIMO onto another level.
