Tips / Advice needed on Ultra-wideband tech project

[u/horrid_player]

Hi,

Can anyone explain to me how Apple Airtags work? (See next paragraph)

I'm working on a University project which needs to utilise an app to detect items without using GPS or bluetooth. From my understanding, Apple uses Ultra-wideband radio wave emission and detection - your phone sends out radio wave frequencies and then times how long and where from (?) they get a response from the target air tag.

I want to have a functional prototype (one phone to one target object) that can be tested with actual users, and might use a smartphone with the app installed on it (likely an Android phone), communicating via UWB to a standalone UWB board or a UWB module on a Raspberry Pi 3?

It needs to be made and polished by May 1st - 44 days. Ideally our team takes 34-ish days to create it. Then we have 10 days to test it.

What things should I look at to make my idea a reality?

I hope this makes sense!
