I am confused. I thought "permissive change" referred to the ability of a device maker to avoid having to do a full fcc recertification when making changes to their device (hardware or firmware) that did not affect rf emissions

My mistake here actually. They still need to go through FCC testing but they can enable already deployed devices through SW/FW updates.

Correct me if I am wrong it was a long time since I checked the progress.

AFAIK, EU/UK, Korea only has plans to discuss and move forward on selected spectrum sometime in mid 2021. No exact date has been announced unlike the US. Which is a done deal. i.e It is not likely any part of the world other than US to get 6Ghz in 2021.

> Class II Permissive Change

Is that new? I remember Smartphone cant add new frequency spectrum support without going through FCC recertification again . Although that was many years ago.

Korea has rules in place since October, 2020. Certification has started. Samsung Galaxy S21 supports Wi-Fi 6E in Korea now [1]

UK/EU is in final stages of regulation. Final approval for EU countries is in March 2021; and after April, countries will implement it in their rules.

Brazil has approved their rules today! Chile and some other countries have rules in place as well.
