WiFi-6 high density design question

Hi Community,

 

I am reading on Meraki high density design guide that 20 MHz channel with WiFi5 (ac) deployments is recommended, now considering WiFi6 (ax)  can we assume the same or is it more efficient (remember, for high density) to have instead a 40 MHz channel width considering that it doubles the number of RUs (Resource Units) ?

 

ADD: I forgot to mention that one more reason I was thinking about this is because of BSS coloring that supposedly should make channel reuse less impacting between APs (of course I guess all this in a pure WiFi 6 client scenario)

 

Thank you in advance

For the RU usage, you need the ax-clients as every ac-client will occupy the whole spectrum. For BSS-coloring, it still needs to be shown to have significant benefit in the wild (outside of marketing presentations). So yes, I would stick with 20MHz.
