What is Bluetooth AoA Technology?
Based on the latest BLE (Bluetooth Low Energy) Bluetooth 5.1 Technology, Blueiot applies the Angle of Arrival - Bluetooth AoA positioning algorithm to reach the unique direction of the incoming wave and position of the tag, which can reach 0.1-meter accuracy and improve the accuracy of traditional low-precision Bluetooth by 10 times.
With Bluetooth 5.1 AoA direction finding technology, Blueiot locating anchor is backward compatible with all Bluetooth 4.0 or above tags and supports the high-precision locating service for both BLE AoA tags and LBS phones.
Standing out of high compatibility, high accuracy, and low energy, Bluetooth 5.1 AoA technology has become the main driving indoor positioning technology for industry 4.0.
An AoA anchor calculates the actual heading angle/pitch angle of the tag, and obtains a unique ray. Then according to the height of the tag, this anchor can calculate and obtain the unique spatial absolute coordinate.
The strapdown combination of multiple anchors obtains a larger positioning coverage space, and multiple anchor course angel calculations improve the global spatial accuracy level.
