Indoor Locationing
summary
Covers practical use of WiFi RTT (802.11mc) on Android Pie/10 with Pixel phones and Google Wi‑Fi APs, including a sample app and a custom demo that trilaterates using multiple AP ranges and the lemming apex trilateration library. Claims theoretical ~30 cm resolution but reports 30 cm theoretical vs 1–2 m measured standard deviation in real settings, jitter near metal shelving, sensitivity to AP placement and altitude, and Android 10 responder LCI provisioning; useful if wanting gritty deployment details rather than high‑level marketing.
