Do the new Wi-Fi 7 APs support UNII-4 and UNII-5 channels?

Do the new Wi-Fi 7 APs support UNII-4 and UNII-5 channels? I remember Wi-Fi 6E APs did not support them. Please let me know if you are aware of any such documentation. 

Thanks,

Gina

It's not listed on the 9176 or 9172 datasheets, but the 9178 does list the supported bands and those are not included: https://documentation.meraki.com/MR/MR_Overview_and_Specifications/CW9178I_Datasheet

My assumption would be if the highest model doesn't have them, the lower levels won't either, but your account rep may be able to have an SE confirm.

Hi @GinaR,

In this case, we need to distinguish UNII-4 and UNII-5 since 4 relates to 5 Ghz band, and UNII-5 is already considered 6 Ghz (although technically, the first usable channel starts on 5.945) mark. I checked it with my CW9178I in Europe, and in 6 Ghz I can select UNII-5 channels, so that means that UNII-5 are supported.

When it comes to UNII-4, these channels are greyed out, and here I'm not sure if this is because the AP don't support it, or the regulatory domain doesn't allow it. From what I'm reading, it seems like UNII-4 is not supported in many regions, and on top of that, UNII-4 channel ends on 5.925, which is quite close to the UNII-5 at 5.945, which can potentially create sideband interference. Again, not sure if that's the case here since I couldn't find any official confirmation, but my "educated guess" is that UNII-4 isn't supported.

I hope that makes sense, and always happy to be corrected if someone has something to add 😉
