Indoor Factory (InF) Positioning
Sub-20 cm Localization for Industrial Industry 4.0
Standardized profile delivering sub-20 cm horizontal accuracy in metal-rich indoor factory environments characterized by severe multipath reflections.
Technical Explanation
Industrial factory floors present the harshest radio propagation environment on earth: massive metal machines and overhead cranes reflect radio waves into dozens of false multipath paths. Rel-18 Indoor Factory (InF) positioning combines high-frequency mmWave wideband signals, carrier-phase tracking, and AI multipath deconvolution to achieve 15 cm accuracy.
Key Functions
- Delivers verified sub-20 cm horizontal and vertical localization in metal-dense factories
- Deconvolves complex multipath reflections generated by industrial steel machinery
- Guides automated forklifts, autonomous mobile robots (AMR), and overhead gantry cranes
- Replaces expensive proprietary optical camera and ultra-wideband (UWB) tracking systems
