Unveiling BLE AoA Indoor Positioning: Precision at a Price

In the pursuit of precise indoor positioning and tracking, two wireless technologies have emerged as frontrunners: Bluetooth Angle of Arrival (AoA) and Ultra Wide Band (UWB). While both are highly capable contenders, they offer distinct advantages and considerations. In this blog article, we’ll delve into the world of Bluetooth BLE AoA from Blueiot‘s products and compare it to UWB, exploring their unique attributes and helping you determine which is the right fit for your needs.

Accuracy: Pinpointing with Precision

When it comes to accuracy, UWB vs BLE technology takes the lead. With typical accuracy ranging from 0.1 to 0.3 meters, UWB offers unparalleled precision in location tracking. On the other hand, Blueiot’s BLE AoA provides a respectable accuracy range of 0.1 to 0.5 meters, making it suitable for applications that require slightly lower precision.

Refresh Rate: Striking the Balance

For applications that demand real-time location updates, UWB offers a high refresh rate, ensuring that tracking data is constantly updated. However, Blueiot’s BLE AoA provides a medium refresh rate, which is still sufficient for most use cases where immediate updates are not essential.

Compatibility: Diverse Devices and Tags

Blueiot’s BLE AoA effortlessly integrates with a wide range of devices, including mobile phones, wristbands, watches, and transmitters. This adaptability makes it a versatile choice suitable for various applications. On the other hand, UWB tags are specifically designed for UWB anchor systems, limiting their compatibility to specific UWB-based setups.

Power Consumption: Balancing Efficiency

In terms of power consumption, Blueiot’s BLE AoA tags have the advantage of low energy requirements, ensuring extended battery life for devices. Conversely, UWB tags consume relatively higher power due to the enhanced functionality and precision they offer.


UWB and Blueiot’s BLE AoA solutions each possess unique strengths that cater to specific needs in the realm of location tracking and IoT. Meanwhile, BLE offers a more cost-effective option with lower power consumption, making it ideal for certain applications that prioritize efficiency and affordability. By understanding these technological distinctions, businesses can make informed decisions when choosing between UWB and Blueiot’s BLE AoA solutions, unlocking the true potential of location tracking in their respective industries.
