BLE AoA Technology

Blueiot-Bluetooth AoA

BlueIOT uses the Angle of Arrival (AOA) positioning algorithm to reach the unique direction of the incoming wave and position of the tag, which improves the 5-meter accuracy of traditional low-precision Bluetooth by ten times, and reaches 0.1-0.5 meter average accuracy. The system supports Bluetooth 5.1 and is backward compatible with all Bluetooth 4.0 tags or phones.

Single area Two-dimensional positioning in single anchor area

A single gateway calculates and obtains the actual heading angle/pitch angle of the tag, and obtains a unique ray. According to the determined tag height, a single gateway can calculate and obtain a unique spatial absolute coordinate.

Large area spatial positioning

The strapdown combination of multiple gateways obtains a larger positioning coverage space, and multiple anchor course angel calculations improve the global spatial accuracy level.
