MU-MIMO stands for multi-user, multiple-input, and multiple-output, and supports up to eight concurrent users accessing Wi-Fi 6 networks in both uplink and downlink scenarios. MU-MIMO in Wi-Fi 6 enables high-speed networking and meets the tremendous demand for large network capacity with increased throughput and efficiency. Compared with Wi-Fi 5, Wi-Fi 6 improves the downlink capacity by two times and the uplink capacity by eight times.
