The AoA Enterprise Kit is a high-precision Angle of Arrival (AoA)-based real-time location tracking (RTLS) package optimized for large-scale environments. With ORBRO Server and ORBRO Edge (AoA), multiple TwinTracker AoA and PoE switches are provided together for accurate indoor location data collection and analysis. This kit enables the construction of ORBRO OS-based AoA location tracking system, which supports the presence of objects in the zone, proximity detection, directional based location calculation, and precise angle tracking with the BLE tag. In particular, it is suitable for precise location service and advanced RTLS environments as it can analyze the direction of movement and entry of people/assets. ORBRO Server is also included to reliably handle more data than the Starter Kit, ensuring high scalability and reliability in medium and large deployments.
