I've seen a few demos of the AoA and AoD features of Bluetooth 5.1. In general these demos are highly controlled are done at ranges of ~1m between the Tag and Receiver. For indoor Location/Positioning was is the realistic range that AoA/AoD will work considering the effects of indoor multi-path propagation? There has been much made about the increase accuracy of 5.1 compared to traditional RSSI triangulation, but I'm unclear how it address the indoor multi-path problem. Can some comment on this? Is the method uses less prone to these issues?
