Exploring the Principles of Bluetooth AoA Technology in Blueiot’s High-Precision Positioning System

Bluetooth positioning has revolutionized indoor tracking and monitoring, offering businesses precise and real-time location data. In this article, we will delve into the   behind Blueiot‘s Bluetooth AoA Technology.

  1. Hardware Layer:

Blueiot’s Bluetooth AoA system comprises two essential components: the Blueiot RTLS Tags and the Blueiot RTLS Anchors. The RTLS Tags are attached to people, assets, and vehicles, transmitting direction-finding signals. In addition, the RTLS Anchors utilize antenna arrays to produce phase differences when receiving these signals. This hardware layer forms the foundation for accurate and reliable positioning.

  1. Calculation Layer:

The Calculation Layer plays a crucial role in the Bluetooth AoA system. It collects data from the anchors, including the phase differences, and employs advanced algorithms to calculate the X, Y, and Z coordinates. These coordinates are then communicated to upstream applications, enabling businesses to access real-time location information with high precision.

  1. Application Layer:

The Application Layer is where the true value of Blueiot’s Bluetooth AoA system comes to life. This layer encompasses a range of functionalities, including location mapping, trajectory tracing, geo-fencing, alarms, camera integration, attendance tracking, work hours statistics, and patrol tasks. These features empower businesses to optimize their operations, enhance security, and improve overall efficiency.


Blueiot’s Bluetooth AoA Technology operates on a three-layered platform, enabling businesses to achieve high-precision positioning within indoor environments. With its robust hardware layer comprising RTLS Tags and Anchors, the Calculation Layer’s sophisticated algorithms, and the diverse functionalities offered at the Application Layer, Blueiot provides a comprehensive solution for location-based applications.
