>> It is not clear whether 6Ghz support is mandated to be certified as WiFi 6E.
It is.
>> Could we get new spectrum support via Firmware update?
Yes. In US/FCC, the procedure is called "Class II permissive change".
Also, US, Korea, EU/UK, Chile, Brazil have opened up 6 GHz band. More countries will follow in coming years.
- maguirre 6y agoI 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
- tradertef 6y agoMy mistake here actually. They still need to go through FCC testing but they can enable already deployed devices through SW/FW updates.
- ksec 6y agoCorrect 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.
- tradertef 6y agoKorea 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.
