A few questions on UWB on iOS

I’m thinking about making an app that requires two UWB things to work. I can’t seem to find anything about them and I haven’t got the money to just try it out. The questions are:

  • how far can the iPhone be to a moving UWB chip to make a connection?
  • can this work in the background? If so, is it intermittent?

i need to be able to detect moving objects pretty reliably and have the app respond when it isn’t open. I guess a bit like the Covid tracking stuff.

would the Apple frameworks allow for me to do this?

Hello @Hobson,

I recommend that you watch this WWDC session to learn about Nearby Interaction background sessions (link is timestamped to the relevant portion of the video):

As for your question about UWB range, I don't have figures to share, though I can say that second generation UWB chips support Extended Distance Measurement (see Extending advanced direction finding and ranging).

Best regards,

Greg
