1) EHT PHY Wi-Fi 7 获准通过将 MU-MIMO 中的带宽和 SS 数量加倍来扩展先前 Wi-Fi 标准的 PHY,这将标称吞吐量提高了 2 × 2 = 4 倍。PHY 还通过利用 4K-QAM 引入了更高速率的 MCS,使标称吞吐量增加了 20%。因此,与 Wi-Fi 6 的 9.6 Gbps 相比,Wi-Fi 7 将提供高达 2×2 × 1.2 = 4.8 倍...
I tried enabling the OFDMA/802.11ax MU-MIMO setting on the 2.4 GHz band and that has negative effect. On the 5 GHz band the OFDMA/802.11ax MU-MIMO defaults to DL OFDMA Only. Any other setting seems to have a negative effect. The negative effect is that the clients only ...

这可能在超过一个sta选择相同ltf序列的情况下发生。这在以下示例中示出。图2示出了ap 203与sta 201和202之间的示例性ul mu接入200的框图,其中非冲突的空间流受到冲突的空间流的影响。在该示例中,h矩阵是ap 203与sta 201和202之间的物理mimo信道系数矩阵,h...
However, is there any downside to enabling these two settings (Multi-User MIMO and OFDMA/802.11ax MU-MIMO on the Wireless -> Professional page) on the off chance some of my devices do support it? By default both settings are disabled for 2.4 GHz (for 5 GHz, Multi-User MIMO...
