A critical technology for managing multi-user traffic in recent Wi-Fi standards is Multi-User Multiple-Input-Multiple-Output (MU-MIMO). Downlink (DL) MU-MIMO was introduced with Wi-Fi 5 and assisted us with downloading large files or streaming videos simultaneously. Still, as our applications became more complex, with live video sharing and video conferencing, the need for support in the uplink (UL) for multiple users on the same network became a critical element of Wi-Fi 6.
As a pioneer and a vocal proponent for multi-user technologies and scheduling techniques, Qualcomm Technologies has delivered a highly differentiated MU-MIMO implementation. In this whitepaper, we quantify the value of MU-MIMO vs. SU-MIMO and our implementation vs. the competition to demonstrate MU-MIMO's scalability and performance benefits in various real-life deployments, including home, enterprise, and classroom scenarios.
