As an AOA positioning provider, Dusun 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.
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.
The strap-down combination of multiple gateways obtains a larger positioning coverage space, and multiple anchor course angel calculations improve the global spatial accuracy level.

It can be used as a positioning base station for AoA, or as an IoT gateway to connect sensors and devices. It supports the Wi-Fi, BLE5.2, Z-Wave, Zigbee wireless protocol.
The AOA gateway calculates the exact position based on the data in the figure below to realize real-time indoor positioning.
After fixing the base of the AOA gateway to the wall with three screws, buckle the gateway into the buckle.
Various types of beacons, suitable for indoor and outdoor use, easy to install, support iBeacon protocol and Eddystone protocol.
Smart devices comply with the wireless certification and security certification, FCC, CE, CCC, UL.
The gateway opens the API interface to facilitate the docking of various systems and platforms.
The standard Bluetooth health protocol makes docking easier and easier.
The gateway comes with a standard Luci configuration page, making it easier to access the cloud on the device.
Multiple types of gateways and beacons for a wide range of scenarios, meeting waterproof, outdoor conditions.
When AOA TAG is moving, the packet frequency is different than when it is stationary. The opposite is true when it is stationary. When in a stationary position, the AOA’s TAG packet sending frequency corresponds to a broadcast interval of 100 milliseconds. The AOA’s TAG packet frequency has a broadcast interval of 2 seconds when the vehicle is in motion.
Yes, it is currently supported for the customer to select 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 system requires a minimum of two 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 gateway is approximately the shape of a circle, and the height difference between the gateway 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 locator from adjacent walls and columns.
Customers can acquire platform-side positioning engine services by going through our third-party partner, Navigine.
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. Customers have access to the code located in the source code of our software development kit (SDK).
We use the most recent version of the Bluetooth protocol stack, which is version 5.3, and it supports the most recent version of the AOA Bluetooth 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 can reach 0.3 meters under ideal conditions.
AOD (Angle of departure) requires each terminal TAG to install an array antenna, while the AOA direction finding system only requires the locator to install an array antenna. Therefore, the relative cost will be lower.
We are glad to have Dusun as our strategic partner. Dusun is an excellent provider of IoT hardware, which capabilities amplify the possibilities of our software. Joint solution of Dusun and Navigine is applicable to various industrial scenarios, from healthcare to manufacturing. We believe that together we can provide numerous benefits for our customers.
The inability of one party to provide the necessary hardware is remedied by DUSUN’s provision of the Poland platform Navigine with an AOA locator and an AOA TAG, thereby assisting the platform in the development of a more effective solution.
All devices have open API interfaces, which can be connected to customers’ private and shared platforms.
