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