AoA locators can be used for increasing the accuracy of location capabilities for Bluetooth devices such as Tag, Beacons, and Smartphones. AoA locators allow Bluetooth signals to track and locate other Bluetooth-enabled devices when using triangulation. Where trilateration relies on signal strength, the triangulation uses the timing differences in the reception of tags’ signals. This makes triangulation technology far more reliable for locating Bluetooth signals.
AoA locators send signals to a public cloud from indoor or outdoor beacons, smart watches, and mobile devices to a user’s private cloud. In addition to serving as a positioning gateway, an AoA locator can also support WiFi, BLE5.2, Z-Wave, and Zigbee protocols to connect sensors and devices.
AoA standing for Angle of Arrival is based on the principle of transmitting a specific direction-finding signal using one antenna.
The receiving device features an array of antennae that read the signal phase difference between the signal-transmittingantenna and its many antennae.
Using sample data, the receiving device calculates the relative signal direction. Radio direction finding is not necessarily new technology.
Dusun AoA locators have many benefits. In addition to their increased accuracy, they have a battery life of up to five years for long use. Thanks to the Bluetooth ecosystem, they are a cost-effective way to create more accurate tracking for devices indoors and out. An AoA locator can support a high tag density without using much power.
Dusun AoA locators also support a multitude of tags, including:
