System OVERVIEW
Indoor Navigation System for UWB-Enabled Phones is a DL-TDoA-based UWB indoor positioning system designed to turn UWB-enabled smartphones into positioning terminals. The system enables tag-free, high-precision indoor navigation and spatial services across large-scale environments.
By leveraging UWB anchors, spatial maps, and navigation algorithms, the system delivers real-time positioning, route guidance, and arrival detection directly on smartphones. It supports both iOS and Android ecosystems, enabling cross-platform deployment in complex indoor spaces.
With UWB now widely available on recent iPhone models and expanding across Android devices, the system provides a scalable foundation for next-generation indoor spatial intelligence.

Positioning
Key Points
- Beacons broadcast periodically, and the terminal estimates distance or proximity based on RSSI.
Key Points
- The terminal actively transmits Bluetooth signals, and an antenna array at the base station measures the angle for positioning.
Key Points
- Base stations transmit UWB signals in downlink mode, and smartphones passively receive and participate in positioning computation.
Key Points
- 5–10 m, room-level positioning; suitable for approximate location awareness
Key Points
- 0.5–3 m, meter-level to sub-meter positioning; supports zone and lane-level positioning
Key Points
-
10–30 cm accuracy
supports precise point positioning, route guidance, and real-time navigation
Key Points
- Affected by human blockage, mobile phone orientation, and multipath effects; may cause signal drift, positioning deviation, and location misjudgment
Key Points
- Affected by antenna installation, signal blockage, and reflections; positioning accuracy may fluctuate in complex environments
Key Points
- Strong multipath resistance with stable and continuous positioning performance
Key Points
- Beacon broadcasts signals while mobile phones scan them; high-density deployments may cause scanning congestion and channel conflicts
Key Points
- Large-scale deployments increase RF load and processing requirements; signal interference and computing pressure may increase
Key Points
- Base stations broadcast signals while tags perform local calculations; highly scalable architecture
Key Points
- Signals may be captured by third-party devices; data access, upload scope, and anti-tracking require additional management
Key Points
- Bluetooth signals and positioning data require additional protection mechanisms
Key Points
- Supports secure ranging and encrypted communication; local data processing reduces data exposure
Key Points
- Requires dense device deployment; battery maintenance and environmental calibration may be needed
Key Points
- Requires precise antenna installation, calibration, and commissioning
Key Points
- Requires fewer base stations and provides stable long-term infrastructure operation
Key Points
- Limited device status monitoring; requires manual inspection and battery maintenance
Key Points
- Requires periodic testing, calibration, and optimization
Key Points
- Supports centralized monitoring of base station status, synchronization, network conditions, and system updates
