Bluetooth AoA vs. UWB Indoor Positioning
Bluetooth AoA (Angle of Arrival) and UWB (Ultra Wide Band) are both wireless technologies that can be used for location tracking and positioning. However, they use different methods to achieve this goal.
Bluetooth BLE AoA is a location-based technology that can accurately determine the location of Bluetooth devices. Bluetooth AoA locating system offers the advantages of high accuracy, low power consumption, increased security and flexibility, making it an ideal choice for warehousing & logistics , healthcare, manufacturing, retail, transportation, public security, etc.
Ultra Wide Band (UWB) is a technology to transmit data by sending or receiving narrow pulse across a GHz level bandwidth. 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.
In conclusion, Bluetooth AoA is easier to implement because it uses existing Bluetooth infrastructure, while UWB has a longer range and higher accuracy, but requires a dedicated UWB infrastructure and is more expensive to implement.
