This video explains real-time asset tracking using different methods: a signal strength measurement (Bluetooth 4.0), a signal strength measurement combined with Angle of Arrival direction finding (Bluetooth 5.1), and the Time Difference of Arrival method (Ultra-wideband). The achievable accuracy is 5-8 meters with Bluetooth 4.0, about 0.5-1 meters with Bluetooth 5.1 and less than 50 centimeters with UWB.
