Love reading about these types of R&D efforts, especially when they are successful. I started in robotics in 01 and was present at some of the first commercial vSLAM efforts and materially contributed to a hardware solution utilizing IR beacons on the ceiling. We also looked at RF radio mapping at the time, but the computational power wasn't there. Great to see how far it has come and LOVE that it doesn't require infrastructure!

I am curious how deeply you have had to study the impact of how busy the store is with your signal error? Considering that humans are bags of water which is quite detrimental to RF signals, my guess is that your error increases along with the density of people.
