I am pursuing a PhD in indoor localization, and UWB is still far superior. That is the reason why major phone companies still include a UWB chip and are not switching to BLE 6.0.
I have compared them, and because BLE is a narrowband signal, it is highly susceptible to Non-Line-of-Sight (NLOS) conditions compared to UWB.
I also attended a prototype presentation by a large European silicon company. I noticed that even in their demo, BLE did not achieve 30 cm accuracy, but rather hovered around 1 m.
I have only tested PBR and RTT ranging with a simple Kalman Filter, so maybe someone has found a clever combination of these data sources (I hope).

Are there any good alternatives? We need something to prevent replay attacks on app based phone far keys..
Cool, I worked on indoor localization, particularly with RTT, at Google for many years :)
Maybe we can get in touch, I am curious to have a more senior perspective on the indoor localization!
Is there a good list of cars that support UWB? Seems like a requirement for my next car...
All the new car have the keyless option and use UWB to open and close.
