ⓘ Detailed Overview

Indoor positioning systems (RTLS) are essential for industrial automation where GPS fails due to signal obstruction. This presentation covers three primary business drivers: safety (accident prevention and equipment protection), productivity (asset location, utilization optimization), and automation (autonomous robots, drones, AGVs). The technology works by installing stationary beacons (anchors) on walls and ceilings as reference points, while mobile beacons attach to assets or personnel. The system calculates precise location data through time-of-flight measurement with centimeter-level accuracy—far exceeding GPS's meter-level precision. Critical to success is maintaining line-of-sight between mobile beacons and at least two anchors (2D tracking) or three anchors (3D tracking) within 30-meter range. Data flows through a central modem/controller via radio in license-free bands, accessible through USB or pin connections. Unlike camera-based tracking, beacon systems work in poor lighting and uniform environments. The infrastructure scales efficiently—larger warehouses simply require more stationary beacons without capacity limitations. Stationary beacons typically use grid power with battery backup lasting years between charges, while mobile beacons run on smaller internal batteries.
