I think they gave it two wireless adapters for basically that purpose. That way it and the computer can form a dedicated channel where they don’t need an intermediary for better performance.
It will also contain the PC rendering through SteamVR for heavier titles, right? Like Valve Index, but wireless?
Yes! You can wirelessly connect it to a PC and use it like the Index.
