If you make the bump to Bluetooth 5.1+ RTLS like this get even more interesting as you can measure not only signal strength, but angle of arrival too. Nordic Semiconductor have some beautiful development kits [1] for this if you want to play. Cisco also have quite a nice write-up [2] on other approaches to location resolution from WiFi and BLE. It's worth acknowledging that setups like this exist in most workplaces, shopping centres, stadiums and other public spaces in many developed countries. 'Free wifi' is not there for your benefit. There are useful experiences enabled by this which may make your life simpler in some contexts, but also worth being cognisant of how common this is.
