OFDMA enables managed, reliable, efficient connectivity across more devices. This means plenty of headroom for future growth or fewer APs required to support existing devices. OBSS enhancements
MIMO vs MU-MIMO: Analysis of Key Technologies in Wireless
Both MIMO and MU-MIMO enhance wireless performance through multi-antenna technology. The former focuses on efficient transmission of a single device, while the latter solves the
Performance evaluation of OFDMA and MU-MIMO in 802.11ax networks
They show that UL OFDMA without MU-MIMO may outperform single-user transmissions by 273%, and the use of both UL OFDMA with MU-MIMO may improve the WLAN performance by
Multi-User MIMO in WiFi 6
MU-MIMO improves the overall system performance by leveraging multiple spatial streams to serve multiple users simultaneously. Combining MU-MIMO and OFDMA further boosts performance by
802.11ac Wave 2 with MU-MIMO: The Next Mainstream Wi-Fi
In comparison, 802.11ac Wave 1 uses SU-MIMO (single user MIMO) to address multiple clients sequentially, using beamforming to direct the signal preferentially to each client. Chip vendors say
