Comparing UWB and Bluetooth AoA for Indoor Positioning: Which Technology Holds the Edge?

When it comes to indoor positioning and location tracking, two prominent wireless technologies have emerged as key contenders: Ultra Wide Band (UWB) and Blueiot Bluetooth Angle of Arrival (AoA). Both technologies offer unique advantages and varying levels of accuracy, making them suitable for a range of applications. In this article, we will explore the differences between UWB vs Bluetooth, shedding light on their protocols, accuracy, compatibility, power consumption, and costs.

Protocol and Compatibility

Blueiot Bluetooth AoA relies on the Bluetooth 5.1 protocol for accurate location determination. It can be seamlessly integrated with a wide array of devices, including mobile phones, bracelets, watches, and Beacons, making it a versatile solution. On the other hand, UWB employs its own dedicated protocol, requiring specialized UWB tags for tracking purposes. While Blueiot Bluetooth AoA enjoys broader compatibility, UWB demands specific hardware for implementation.

Power Consumption

Power efficiency is an important consideration for any tracking technology, particularly in battery-powered devices. Bluetooth AoA excels in this area, boasting low power consumption that extends the battery life of tag devices. However, UWB consumes relatively higher amounts of power, which may impact battery longevity, especially in resource-constrained environments.

IoT Capabilities

Bluetooth AoA offers Internet of Things (IoT) anchor capabilities, making it compatible with the broader ecosystem of IoT devices. This enhances its potential for integration with various IoT platforms and applications. UWB, however, lacks built-in IoT capabilities, limiting its direct compatibility with the IoT landscape.


In conclusion, the choice between UWB and Bluetooth AoA for indoor positioning depends on specific requirements and constraints. Bluetooth AoA holds advantages in terms of ease of implementation, compatibility, power consumption, and affordability, making it a versatile option for a wide range of applications. On the other hand, UWB shines in scenarios that demand unparalleled accuracy and stability, albeit with higher costs and a need for dedicated infrastructure. By considering the unique features of each technology, businesses can determine the most suitable solution to meet their indoor positioning needs.
