Experiments carried out in the past (from 2011) are described hereafter:

- I have managed to use the fantastic DWM1000 chip:
- This chip, manufactured by Decawave can be used for in-door localization. It is based on the measurement of the time of flight of radio waves.
- I have used small Arduino pro mini at 3.3V to drive the chips. Hopefully, all the dirty work has been done by Thotro who provides a nice librabry, see here and there.
- To solder the chip, I use a breakout board designed by Wayne and manufactured on demand by OSH park.
- One VERY important thing to now: the power supply must be strong enough to support the peak current demands of the DWM1000. If the power supply is too weak, it will work very erratically. By the way, if you use one of those small breadboard power supply, do not forget to add a LARGE CAPACITOR (see the pictures).
- Up to now, I only use the existing library which gives me 3 distances. Now, I have to implement some smart trilateration algorithm.
- Here is a picture of the 3 "anchors" and the tag:
