Separately, though, I'm reminded of my experience with UWB (ultrawideband) Airtags with a recent-model iPhone... THAT worked phenomenally well. It was kinda magical to experience. But I don't think you could easily scale that up to a mesh of Airtags scattered around a building, at least not out of the box. And many Androids don't have UWB radios at all or don't have the software support to enable them yet. Google is way way behind on this =/ They finally launched a few this year with some partners, to middling reviews.
