8 x 8 MU-MIMO Biggest Benefit in Wi-Fi 6 for Data Throughput, Says SA

With full eight transmit and eight receive antennas, 8 x 8 MU-MIMO provides the biggest benefit to total system throughput and capacity in Wi-Fi 6 networks vs. other features of Wi-Fi 6, said Strategy Analytics Friday. Marketing messages about Wi-Fi 6 have typically focused on benefits of orthogonal frequency-division multiple access (OFDMA), important for reducing congestion, but access points with 8 x 8 MU-MIMO can simultaneously address up to four times as many 2 x 2 client devices as OFDMA alone, said analyst Christopher Taylor. Many entry-level and mainstream Wi-Fi 6 access points use only two or four antennas, but more than two-thirds of access points SA identified in the premium tier use the full eight, he said, highlighting Quantenna, Qualcomm, Marvell and Celeno as suppliers of Wi-Fi 6 chipsets capable of 8 x 8 MU-MIMO. “The benefits of MU-MIMO have been proven in the cellular world with LTE,” and smartphone and laptop PC OEMs have shown strong support for Wi-Fi 6 with MU-MIMO, said analyst Stephen Entwistle.
