tosensei1766148dhmmm. couldn't you just have used RFID-triangulation with off-the-shelf components?
Geoxion918148d@tosensei with RFID you need to be close to the device already, within 1-2 meters I believe.
UWB radio has a range of 50-150m so it would've been possible to track every device everywhere indoors at a ny time.
You could look up the location from your PC and then walk to that location
Voxera10772148dThat sounds like a quite interesting tech :)
A bit like the apple airtags, andI can see that with the right marketing it could probably be quite popular in some industries.
But the synchronization could be a problem I guess as I assume it needs calibration when setup?
Geoxion918148d@Voxera yes it does need calibration and the radio chip manufacturer describes the setup in which you can do that.
However, I made it so it was auto calibrating.
There are a lot of anchors and so every anchor is within receiving distance of a couple of other anchors.
We know the position of every anchor.
So when they synchronize to each other, we can calculate how far they think they are apart and compensate for that using the real distance they are apart.
I don't remember the numbers exactly but I think it was roughly that an uncalibrated device had an accuracy of 10-20cm and calibrated around 1-2cm
