They're doing it over 6GHz, if I understand correctly, which with a dedicated router gets you to a reasonable latency with reasonable quality even without foveated rendering (with e.g. a Quest 3).
With foveated rendering I expect this to be a breeze.
Even 5.8Ghz is getting congested. There's a dedicated router in this case (a USB fob), but you still have to share spectrum with the other devices. And at the 160Mhz symbol rate mode on WiFi6, you only have one channel in the 5.8GHz spectrum that needs to be shared.
You're talking about "Wi-Fi 6" not "6 GHz Wi-Fi".
"6 GHz Wi-Fi" means Wi-Fi 6E (or newer) with a frequency range of 5.925–7.125 GHz, giving 7 non-overlapping 160 MHz channels (which is not the same thing as the symbol rate, it's just the channel bandwidth component of that). As another bonus, these frequencies penetrate walls even less than 5 GHz does.
I live on the 3rd floor of a large apartment complex. 5 GHz Wi-Fi is so congested that I can get better performance on 2.4 in a rural area, especially accounting for DFS troubles in 5 GHz. 6 GHz is open enough I have a non-conflicting 160 MHz channel assigned to my AP (and has no DFS troubles).
Interestingly, the headset supports Wi-Fi 7 but the adapter only supports Wi-Fi 6E.
Not so much of an issue when neighbors with paper thin walls see that 6ghz as a -87 signal
That said, in the US it is 1200MHz aka 5.925 GHz to 7.125 GHz.
More of an issue when your phone's wifi or your partner watching a show while you game is eating into that one channel in bursts, particularly since the dedicated fob means that it's essentially another network conflicting with the regular WiFI rather than deeply collaborating for better real time guarantees (not that arbitrary wifi routers would even support real time scheduling).
MIMO helps here to separate the spectrum use by targeted physical location, but it's not perfect by any means.

The One Big Beautiful Bill fixed that. Now a large part of this spectrum will be sold out for non-WiFi use.
