Wifi is required for ota. It makes sense because if you loose connection your iPhone, iPod or iPad may be need total restore.
I recommend making sure one is backed up first before proceeding with the upgrade. This morning I backed up 6 devices in my home via wifi then upgraded each over the air. All went smoothly without issues at all. I also instructed some 40 clients to upgrade after backing up and again all went well..... . The bad news I no longer get paid for doing it lol...
