BLUETOOTH 5.1 INDOOR LOCALIZATION STUDY BASED ON ANGLE-OF-ARRIVAL METHOD
Краткое описание
Bluetooth 5.1 is a new technology with a sample of novel features. One of the most significant improvements compared to the previous version is in the enhancement of indoor localization with techniques such as angle of departure (AoD) and angle of arrival (AoA). Up to date, only a modest number of limited practical studies were presented where Bluetooth 5.1-based indoor localization was studied mostly through practical measurements. In this paper we develop a MATLAB model facilitating investigation of AoD and AoA features of Bluetooth 5.1. To validate the developed model, we compare the obtained results with our own empirical studies based on the Texas Instruments Development Kit. Based on the results obtained in MATLAB and the correspond measurement campaign, we quantitatively show AoA performance superiority over other location and positioning methods. The developed MATLAB model can be further used for studies of Bluetooth 5.1 features.
