In this paper, the authors proposes a easy calibration of DOD-based BLE beacon system for an indoor localization application. By the proposed calibration method, we can easily recognize the orientation and location of the beacon even though the beacons are roughly installed. The method uses DOD calculated from RSSI of received beacon signals and sensor information of the mobile handset for calibration...
The authors have proposed a method of estimating the location of the receiving terminal by a triangulation technique using DOD information from the multiple transmitters, which is calculated only from the Received Signal Strength Indicator (RSSI). In our previous study, DODs are calculated using four beacon signals, but the number of the antennas for each array is limited to two, which offers insufficient...
In this paper, we propose estimation method of living body direction using parasitic antennas, where only an RSSI (Received Signal Strength Indicator) is used. The measurements were carried out in an indoor environment, and the experimental results showed that the angular error is less than 9.5° even if the phase information of the received signal is not available.
This paper presents direction of departure (DOD)-based localization technique suitable for indoor environment. Localization is performed by estimating direction from known multiple beacons, where each of them comprises two antennas and 180° hybrid. DOD estimation is performed only from received signal strength indicator (RSSI), which does not have phase information. Indoor measurement campaign has...
