Oculus Quest 2 users will soon get to play PC VR games wirelessly through the new Air Link feature, due to ship with software update v28.

Needless to say, the traditional Link feature through the USB-C cable will still provide the optimal experience. However, if you've got a strong WiFi network and have the Virtual Reality playspace within about twenty feet of your router, then Air Link is a viable wireless alternative.
