Exploring UWB and Bluetooth AoA for Indoor Positioning: A Comparative Analysis

As the demand for precise indoor positioning and location tracking continues to grow, two prominent wireless technologies have emerged as strong contenders: UWB (Ultra Wide Band) and Bluetooth AoA (Angle of Arrival) from the perspective of UWB vs BLE. While both offer the ability to accurately determine the location of devices, they employ distinct methods and have varying advantages and applications. In this blog article, we will delve into the features and capabilities of UWB and Blueiot‘s Bluetooth AoA, shedding light on their key differences and helping you understand which technology may be the best fit for your specific needs.

Bluetooth AoA: Accuracy, Power Efficiency, and Versatility

Bluetooth AoA, built upon the Bluetooth Low Energy (BLE) protocol, utilizes existing Bluetooth infrastructure to enable precise location tracking. One of its prominent advantages is high accuracy, with typical accuracies ranging between 0.1 to 0.5 meters. This makes it suitable for applications in warehousing and logistics, healthcare, manufacturing, retail, transportation, and public security, where knowing the exact location of Bluetooth devices is crucial.

UWB: High Accuracy and Stability at a Cost

Ultra Wide Band (UWB), on the other hand, is a technology that transmits data through narrow pulses across a GHz-level bandwidth. UWB locating systems are known for their high accuracy and stability, with typical accuracies ranging between 0.1 to 0.3 meters. This level of precision makes UWB well-suited for industries like factories, law enforcement agencies, automotive assembly lines, logistic warehouses, and power plants.


In the realm of indoor positioning and location tracking, both Bluetooth AoA and UWB offer valuable solutions with their unique strengths. Bluetooth AoA provides a cost-effective and versatile option with high accuracy and low power consumption. UWB, on the other hand, offers superior accuracy and stability but requires a dedicated infrastructure investment. Understanding the specific requirements and cost limitations of your application is essential in determining which technology best suits your needs.
