I think it depends on whether or not you have good 6ghz connectivity. The headset comes with a 6ghz usb dongle pluggable to your rendering PC for locales without a 6ghz router or good 6ghz penetration, but due to 6ghz lack of wall-penetrating capability, that's probably going to be more/less line-of-sight. The LTT video [0] does explicitly mention the ability to use either mode of connection though- over your existing wifi network, or via their 6ghz dongle. It's somewhat unclear if the headset would function over a non 6ghz connection (regardless of quality- supposedly 2.4/5ghz VR-over-wifi is pretty rough due to channel congestion and maybe bandwidth limits)
The headset is also capable of being its own renderer, ie, it can do 'mobile' vr games (android apks like on the quest, eg). That functionality wouldn't need a connection to your PC at all.
The biggest variation is above 6 GHz: most of the world allows 5.9-6.4 but reserves 6.5-7 GHz for cellular or haven't decided yet if it'll be for wifi or cellular. There's a nice map on https://6ghz.info/
