Abstract
This document describes techniques and systems for indoor localization using Bluetooth high-accuracy distance measurement (HADM). In examples, the described systems and techniques perform a signal-strength scan to identify multiple anchor points and then pair, based on the signal-strength scan, the tagged device with a first anchor point of the identified anchor points. A HADM time slot is set for the first anchor point and at least two additional anchor points of the identified anchor points. A HADM event is initiated, the HADM event including sending a HADM ping and receiving HADM responses from two or more of the identified anchor points. Based on at least a time of receipt of HADM responses received from the two or more of the identified anchor points, the location of the tagged device is calculated.
