OFDM is there because its shorter preamble consumes less airtime than the new HE preamble, so it will be used for those frames that don’t require the bigger HE preamble. There are no HT/VHT Capabilities IE’s in a 6 GHz beacon. Unique HE beacon IE’s indicate support for features inherited from HT and VHT. OFDM and HE-Only – There is no HT or VHT operation allowed in 6 GHz.If the answer is “Just add another SSID for Wi-Fi 6E clients-only,” then I will be disappointed. I still don’t understand how this will work with SSID’s that span the legacy bands to support legacy WPA2 clients as well as WPA3-only clients in 6 GHz.
CISCO ISE 2.4 IPHONE ABANDONS EAP SESSION UPGRADE
Security Upgrade – 802.11ax will make SAE and OWE mandatory replacements for PSK and open auth respectively in 6 GHz.802.11ax is not ratified, so it is still possible for some things to change, but I thought I’d run down what’s different and what opportunities I think were missed with 802.11ax in 6 GHz. Still, there are real protocol differences in 6 GHz 802.11ax operation. It may also be unrealistic to expect 802.11ax client chipsets that operate in the legacy bands in legacy modes to do something radically different using the same radio in 6 GHz.

Of course, it probably isn’t reasonable to expect the same amendment that must provide backwards compatibility in the legacy bands to also do something radically new in 6 GHz. 6 GHz is an opportunity to so radically overhaul 802.11 that we could increment the 802.11 version bit in all 802.11 6 GHz frames (It’s been 0 for the entire history of Wi-Fi).

This mythical mode could also have fantastic new capabilities that would now be possible without legacy PHY requirements. There has been some consternation that 802.11ax should have a greenfield mode in 6 GHz, leaving behind all the protocol overhead used for backwards compatibility in the 2.4 and 5 GHz bands.
