Technical Depth

Core Concepts

• Bluetooth Low Energy (BLE) beacon technology - Small wireless transmitters that broadcast signals to enable location tracking of objects and people within buildings
• Indoor positioning systems (IPS) - Technology that locates objects inside buildings using radio waves, similar to how GPS works outdoors
• Signal processing in industrial environments - Techniques for handling radio signal interference caused by metal structures, dust, and other industrial obstacles
• Trilateration and triangulation - Mathematical methods for calculating position based on distances from multiple beacon reference points

Advanced Topics

• Large-scale beacon deployment strategies for 3000+ units
• Custom signal processing algorithms for metal environment signal reflection and absorption
• RFID reader/writer integration for beacon programming and unique identifier assignment
• Real-time tracking and visualization in 3D factory renderings
• Quality control system integration with manual validation workflows
