Hi Arend,

In 802.11ax D4.0 a new band has been proposed. This series contains
changes to cfg80211 for supporting this band. With 2GHz and 5GHz there
was no overlap in channel number. However, this new band has channel
numbers with a range from 1 up to 253.
At the wireless workshop in Prague, we looked at this and sort of
decided that it'd be better to put all the 6 GHz channels into the 5
GHz
"band" in nl80211, to avoid all the "5 || 6" since they're really the
same except for very specific places like scanning.
Would have liked to be there, but attending is no longer an option
for me. We now have two autistic, non-verbal children and I am the
primary caregiver for the oldest because my wife can't handle him.
Guess I should have checked the workshop notes before working on this
:-) Do you have URL?
Found the netdev wifi workshop page and looked over the slides
quickly, but the notes page is pretty empty ;-)
Agree that most functional requirements for 6 GHz are same as 5 GHz.
There are some 6 GHz specifics about beaconing as well.
This came up in discussion with my colleagues today and I would say
from mac80211 perspective there is more to it than just scanning. In
short the 6GHz band is for HE-only operation so for example only HE
rates may be used. As the bitrates are in ieee80211_supported_band
having a separate 6GHz band seems to have a (slight?) advantage.
Hi, Johannes
Any thoughts on this?
Hi Johannes,
It has been a while so maybe your thoughts are more concrete? ;-p
I really would like this to move forward as I also noticed hostapd
changes being posted for 6GHz support yesterday.
Thanks,
Arend
