Got it today and here is first impressions:
7.17beta4
iperf3 -c server.local -P 5 -t 30 -R
TX power max per regulatory domain, will vary per ch. Tested on multiple chs.
AP around 2m away from STA. STA uses Intel AX210 wlan card whit not that powerful integraded laptop antenas, Fedora linux.
wifi speed tests:
2.4, 20mhz - 150
Power draw: 7w sending
5ghz, 160mhz - avg 800-900, peaks 920 (tops out 1G interface). 70% CPU load , both cores, icq about the same.
5ghz, 80mhz - avg 600-700, peaks 800.
Power draw: 8w sending on widest ch
Power draw idle: 5w
Overall comparing to hap ax3 and cap ax I did feel less powerful antennas, but as you can see, drop is not that much (hap ax3/cap ax pushed about 100mbps more on 80mhz wide ch overall). Otherwise resources are tighter than hap ax3/cap ax, but should not be a problem as this device is meant to be used as AP.
