The purpose of this thesis was to focus on BLE AoA and to investigate how the number and placement of antenna arrays affects the accuracy and precision for indoor positioning in NLOS conditions. The achieved results show that, for the special scenario simulating the inside of a vehicle, there was an improvement in accuracy and precision when adding additional antennas for both AoA and RSSI. In the selected environment, RSSI based positioning even performed slightly better than the more complicated AoA based line-intersection method and improved with more used antennas. The positioning of the antennas also did not seem to affect RSSI much but with AoA there were some combinations that resulted in errors where the lines intersected outside of the test area. The experiments also showed that AoA and RSSI could be used for indoor positioning with a good accuracy for smaller areas.
