Bluetooth AoA vs. UWB Indoor Positioning
Bluetooth AoA (Angle of Arrival) and UWB (Ultra Wide Band) are both wireless technologies utilized for location tracking and positioning, albeit employing different methodologies to achieve this objective.
Bluetooth BLE AoA is a location-based technology adept at accurately determining the location of Bluetooth devices. The Bluetooth AoA locating system offers the benefits of high accuracy, low power consumption, enhanced security, and flexibility, rendering it an optimal choice for a myriad of applications including warehousing & logistics, healthcare, manufacturing, retail, transportation, public security, and more.
On the other hand, Ultra Wide Band (UWB) operates by transmitting data through narrow pulses across a GHz-level bandwidth. UWB locating systems boast remarkable accuracy and stability, albeit at a relatively higher cost compared to other locating technologies. It finds applications in various sectors such as factories, law enforcement agencies, automotive assembly lines, logistic warehouses, power plants, and beyond.
In summary, Bluetooth AoA technology presents ease of implementation as it leverages existing Bluetooth infrastructure, whereas UWB offers a longer range and higher accuracy, albeit requiring a dedicated UWB infrastructure and incurring higher implementation costs.
