<font face="Times New Roman, Times, serif">Hi all,<br>
<br>
Attached are previews of results I'll be publishing in the Part 2
article.<br>
<br>
The same test was run on four routers:<br>
- NETGEAR R7800 (Qualcomm 4 stream AC)<br>
- Evenroute IQrouter v3 (Mediatek 2 stream AC, Wifi stack is
"vanilla"OpenWRT for the MT76" according to Evenroute)<br>
- NETGEAR RAX120 (Qualcomm four stream AX) - OFDMA enabled<br>
- NETGEAR RAX45 (Broadcom four stream AX) - OFDMA enabled<br>
<br>
AP set to Channel 36, 80 MHz bandwidth, WPA2 PSK connection<br>
<br>
Each STA shows 867 Mbps link rate. Signal level ~ -45 dBm.<br>
<br>
iperf3 TCP/IP traffic run simultaneously to all four STAs (Intel
AX200, Win 10, 21.80.2.1 driver)<br>
bitrate (-b): 50Mbps<br>
length (-l): 256 Bytes<br>
DSCP values (--dscp), one per STA: 0 (CS0), 96 (CS3), 160 (CS5),
192 (CS6)<br>
<br>
</font><font face="Times New Roman, Times, serif"><font face="Times
New Roman, Times, serif">200ms interval ping run concurrently
from AP to STA on each pair. Ping is always AP to STA for both
uplink and downlink traffic.<br>
<br>
</font>Congestion was measured using a Qualcomm AX STA associated
to the AP, running 1bps of traffic so that stats could be
recorded.<br>
<br>
Thoughts?<br>
