IIRC Apple uses some proprietary radio protocol (or maybe it’s just Bluetooth) to discover and communicate with nearby Apple products.

It uses Bonjour [1], which has an LGPL reimplementation named Avahi [2]

For the sake of being picky, Bonjour is not a radio protocol (Layer 1), it’s a set of tools which enable zero config networking (Layer 2/3)

I agree, it's not a radio protocol and I wasn't trying to imply that it was. The person I was responding to posited it might be one and I pointed them to the protocol that's used without explicitly correcting them on that point.

It can’t use just bonjour.

Apple devices can detect out of network devices as well.
