BLE AOA POSITIONING HARDWARE SOLUTION

Provide a BLE AOA locator+ beacon positioning hardware solution

Bluetooth AoA Positioning Solution Introduction

As an AOA positioning provider, Dusun IoT uses the BLE 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.Our BLE AoA positioning solution supports Bluetooth 5.1 and is backward compatible with all Bluetooth 4.0 tags or phones.

BLE AoA Positioning Block Diagram

AoA locator is specially designed for indoor positioning, asset tracking, personnel positioning and other industrial uses. The AoA locator acquires signals from card beacons, indoor/outdoor beacons, smart watches and mobile devices, and sends them to the public cloud or the user’s private cloud. In addition to being a positioning device, the AoA locator can also support Wi-Fi, BLE 5.2, Z-wave and Zigbee protocols to meet your needs for linking sensors and other IoT devices.

Three-Dimensional (X, Y, Z) BLE AoA Positioning in Single Anchor Area

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

RTLS Technology Comparision

In the indoor positioning field , BLE AoA, Bluetooth RSSI, and UWB are widely used technologies in the market. The comparison of them is also topics that people in this industry like to talk about. Both BLE AoA Locator and Bluetooth RSSI gateway belong to Bluetooth gateway, an IoT gateway uses Bluetooth protocols. You can see more BLE AoA Locator vs Bluetooth beacon gateway info HERE!

In terms of accuracy, UWB can achieve an accuracy of 0.1-0.3 meters, which is the best. BLE AoA is slightly inferior to UWB, but the accuracy gap is not that large, and it can achieve more than ten times the accuracy of traditional RSSI. Moreover, in terms of power consumption, BLE AoA performs better, and its battery life can reach several years. As to product eco system, BLE AoA is also much more richer. When speaking of the total cost, BLE AoA is obviously the best.

Moreover, BLE AoA positioning enjoys vast market prospects, like in supermarkets, nursing homes, factories, high-speed rail stations, airports, public security and justice, and so on.

BLE AoA Positioning Solution FAQs

When BLE AoA TAG is moving, the packet frequency is different than when it is stationary. while when it is stationary, the situation is the opposite. When in a stationary position, the TAG packet sending frequency of BLE AoA corresponds to a broadcast interval of 100 milliseconds. The TAG packet frequency of BLE AoA, when the vehicle is in motion, has a broadcast interval of 2 seconds .

Yes, Dusun IoT supports for customers’ selection of the broadcast frequency before the TAG is shipped from the factory to the end user. Customers have options to choose from based on their specific requirements.

A BLE positioning system requires a minimum of two AoA locators and has no limit on the number of AoA Tags it can use.

The recommended installation distance is 1.5 times the installation height.

The optimal installation height is 3-10m between the AOA Tag and locator

The area covered by a single Bluetooth AoA locator is approximately the shape of a circle, and the height difference between the AoA locator and the AoA TAG should be equal to two times that difference.

The delay caused by data transmission via Bluetooth and data transmission via the network will need to be factored into the acquisition of positioning data.

At a minimum of 2 meters’ distance should separate the AoA locator from adjacent walls and columns.

Yes, it’s okay. Customers can acquire platform-side BLE positioning engine services by going through our partner like Navigine.

Yes. The RTL library developed by Silicon Labs can be utilized even if the customer is responsible for calculating the AoA value based on the underlying interface. Also, customers have access to the code located in the source code of our software development kit (SDK).

Dusun IoT uses the most recent version of the Bluetooth protocol stack, which is version 5.3, and it supports the most recent version of the BLE AoA positioning technology. The accuracy of the technology can be improved to sub-meter levels, and the level of accuracy that can be achieved in practice. Under ideal conditions, Our BLE AoA positioning solution can reach 0.3 meters .

AoD (Angle of Departure) requires each terminal TAG to install an array antenna, while the Bluetooth Angle of Arrival only requires the AoA locator to install an array antenna. Therefore, the relative cost will be lower.
