UWB vs. BLE AoA: Choosing the Right Indoor Positioning Technology

In the ever-evolving landscape of wireless technologies, two prominent contenders have emerged for indoor positioning and location tracking: Blueiot Bluetooth Angle of Arrival (AoA) and Ultra Wide Band (UWB). These technologies, while sharing the same goal, employ distinct methods and have unique characteristics that cater to diverse applications. In this article, we delve deep into the world of UWB vs BLE AoA, comparing their protocols, accuracy, compatibility, and cost to help you make an informed choice.

Bluetooth AoA: Location Precision at Your Fingertips

Protocol: Bluetooth AoA relies on the Bluetooth 5.1 protocol for anchors and Bluetooth 4.0+ for tags. This makes it compatible with various AoA tags, including mobile phones, bracelets, watches, and Beacons.

Typical Accuracy: The Bluetooth AoA system offers remarkable accuracy, with positioning precision ranging from 0.1 to 0.5 meters. This level of precision is a game-changer for industries like warehousing, healthcare, manufacturing, retail, and transportation.

Refresh Rate: If you’re seeking real-time data, Bluetooth AoA has your back with a high refresh rate, ensuring that you get up-to-the-minute location updates.

Compatibility: One of the strengths of BLE AoA is its compatibility with a wide range of devices. This flexibility makes it an ideal choice for businesses looking to integrate location tracking into their existing infrastructure.


In essence, both UWB and Bluetooth AoA offer powerful indoor positioning capabilities, but the decision should be made based on the unique demands of your project and the trade-offs between accuracy, cost, and compatibility with your existing setup. Both technologies are poised to redefine the way you track and locate in a world driven by precision and efficiency, empowering your business across a wide array of industries.
