infsoft Locator Node AoA 1200

Angle of Arrival (AoA) is an emerging technology that indicates the direction of the signal sources and can be used for tracking assets as well as for indoor positioning and wayfinding. infsoft Locator Nodes AoA use Angle of Arrival for real-time measurement of the direction of a radio signal emitted by a mobile 2.4 GHz transmitter (beacon). Based on the angle and signal strength determined, it is possible to calculate the position of an object equipped with such transmitter with an accuracy of 1 to 3 meters. This opens up opportunities for numerous use cases and makes server-based BLE solutions a favorable alternative to cost-intensive Ultra-wideband (UWB) applications – as long as no centimeter accuracy is required.

In addition to the angle measurement, Locator Nodes AoA provide the full range of functions of the infsoft Locator Nodes 1100.

Functionality of infsoft Locator Nodes AoA 1200

infsoft Locator Nodes AoA deployed in the area of interest detect incoming signals from a mobile transmitter operating on 2.4 Ghz (e.g. BLE beacon). The data are sent to the infsoft LocAware platform®, where the device’s position is computed. Using the infsoft Locator Nodes Management allows accessing charts that highlight the angle a transmitted radio signal comes from.

By using Angle of Arrival technology, even just one Locator Node enables determining the direction of movement of a person or object. This is an important factor for applications such as access control or door control in protected areas. Using infsoft Locator Nodes AoA can reduce the number of required hardware for a localization project.

Using a minimum of three infsoft Locator Nodes AoA (triangulation) allows for continuous positioning and substantially improves accuracy and reliability.

Use Cases for infsoft Locator Nodes AoA 1200

infsoft Locator Nodes AoA are designed to be incorporated into diverse Real-Time Locating System (RTLS) projects for both indoor and outdoor use.

Thanks to a special tracking method utilizing AoA technology and barometric pressure sensors, the localization is so precise that not only the shelf, but also the exact rack position in which an item is located can be determined.

Software solution used: Indoor Tracking
Sensor used: Bluetooth Low Energy (beacons)
Example of use: Tracking of Goods in Logistics

Following smart office concepts, a tracking solution based on AoA offers intelligent functions. The detection of persons moving in a given direction can be used to, for example, realize access control or automation technologies (heating, cooling, lighting) based on head counting.
