  7. 5. Indoor Positioning Bluetooth Angle of Arrival

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Mohammed M T Amer; Khadeeja Gamal Mohammed Atteya; [2020]
    Nyckelord :Angle of Arrival; Bluetooth Low energy; Indoor positioning; Internet of Things; Bluetooth direction finding.; Technology and Engineering;

    Sammanfattning : In this thesis, we present the Angle of Arrival (AoA) technique to detect the direction of a source indoors using radio frequency (RF) signal. This technique estimates the direction of the incoming Bluetooth signal, using a tag as a transmitter and an array equipped with a number of antennas as a receiver. LÄS MER
