An air gap is usually understood to mean an isolated workstation or a
network disconnected from any link to 'the world.'  Faraday cages are
way beyond that basic level and you are talking TEMPEST protection.  The
problem is these terms predate WiFi.

Any device with a live (electrically) radio (WiFI/BT/NFC) has to be
considered connected to the world, especially when you have no access to
the software controlling it.  Can you PROVE that your TV's WiFi won't
quietly associate to a hidden ESSID when the Google Streetview car
drives by and upload your viewing history?  Not doubt it would, PROVE it
won't?

Yes, seriously thinking this way for any length of time will drive you
mad.
