An Experimental Assessment of People's Location Efficiency Using Low-Energy Communications-Based Movement Tracking.

From the tests performed, it appears that there are quite significant variations in BT modules’ sensitivities to signal variations, and the experiments showed that Moto Z3 had the best stability in presenting the correct signal levels (over 60% of the samplings were correctly approximating the real RSSI— Figure 21 , Histogram 3); at the opposite end was the Huawei Mate 20 lite, with only 23% values closer to the real one ( Figure 19 , Histogram 1) and almost all values lower than normal, which denotes an overall reduced sensitivity of the BT-embedded module.
