Dear Wi-Fi enthusiasts,
Recently, I have been investigating ASUS RTAX88U Wi-Fi6 MCS index selection. I have created a conducted test-setup to measure this. I am running a downstream TCP iperf to another ASUS RT-AX88U in bridge mode (aka Wi-Fi station).
I have added a step attenuator between the AP and Wi-Fi station so that I can induce an MCS drop.
On the X axis in the graph below, 0 dB attenuator corresponds to -20 dBm RSSI measured on the Wi-Fi station. Y-axis is the percentage of HE-SU (data packets detected).
I am very surprised by the data as I had expected all the detected data packets to be MCS11 (upto 33 dB attenuation).
Anyone has seen this before? Any comments are appreciated.
