Bluetooth Low Energy Direction Finding Principle

A self-learning mean optimization filter to improve bluetooth 5.1 AoA indoor positioning accuracy for ship environments

“…Despite their low power consumption and long range, they are highly resistant to frequency selective fading and provide a sufficient indoor range. The usage of BLE tags on factory floors and in homes is increasing, so they are becoming very popular for tracking operations ( HajiAkhondi-Meybodi et al, 2021 , Mohaghegh et al, 2021 , Hajiakhondi-Meybodi et al, 2020 , Hajiakhondi-Meybodi et al, 2020 , Alexandrov and Monov, 2017 , Yen et al, 2021 , Huang et al, 2020 , Ye et al, 2022 ). So the Bluetooth 5.1 AoA indoor positioning technology has been proposed.…”
