MIMO antenna arrays have been central to improving the range and capacity of wireless networks for a decade and they will continue to play a significant role in driving 5G standards, with the industry moving towards massive numbers of antennas and other innovations. Huawei says it has completed the world’s first large-scale field trial of a technology it believes will be a 5G candidate, pushing Multiuser MIMO (MU-MIMO) to new limits. It worked with NTT Docomo of Japan to stream live video from an outdoor test in Chengdu, China, to the CEATEC Japan trade show in Chiba. The trial connected 24 devices concurrently, a major advance on current MU-MIMO implementations like those in the 802.11ac WiFi standard. The cell average…
