Thank you for contacting Oculus Support.
I understand that you are wanting to know if the up coming Oculus Quest can be set up using an iPad, that is a great question.
At this time, to set up your Oculus Quest and connect to Wi-Fi, you'll need to download the Oculus app on your mobile phone. The minimum OS requirements for phones to run the Oculus companion app are:
Apple iOS 8+
We do not have any information as whether or not the iPad will work with the quest at this time. The iPad was able to set up with the Oculus Go, so it could be possible.
Please let me know if you have any further questions.
