Angle of Arrival (AoA) positioning algorithm locates the position of an AoA tag based on the signal’s arrival angle. Bluetooth AoA locating system is featured by its sub-meter accuracy, high capacity, high compatibility, low cost and low energy. AoA-based RTLS solutions can be applied to a wide range of scenarios, including healthcare, manufacturing, retailing, transportation, public security, and etc.

UWB locating system boasts high accuracy and stability, with a relatively higher cost than other locating technology. It is often applied in factories, law enforcement agencies, automotive assembly lines, logistic warehouses, power plants, and etc.
