One thing I've discovered, since regretfully now switch over to Plasma Cloud* for my network, is that whilst Macs and iPhones idle their WiFi connections when not in use, AppleTV (especially the 4K version) keeps its connections up and running at full pelt 24/7/365. No idling, even in standby mode.
I've no idea what the security implications of that are - constant renegotiation of rate or an always-on connection.
* I mean, hats off to them for what they've done after Datto shat in the swimming pool, but it don't quite work as you'd expect! Makes my hobbyist IoT tinkering a lot more difficult now.
