Precision ranging for industrial systems
Precision ranging for industrial systems
BLUETOOTH® Channel Sounding enables secure, accurate distance measurement between devices for industrial automation, asset tracking. and access control applications.
Precision ranging through dual measurement methods
- Phased-Based Ranging (PBR): Calculates distance from signal phase changes across channels
- Round-Trip Time (RTT): Uses signal travel time for secure distance validation
- PBR + RTT = Combined advantage: More accurate and secure wireless ranging
Antenna overview
Single vs. multi-antenna
- Works with single or multiple antennas on both devices
- Multi-antenna setups improve performance
Why multiple antennas?
- Better resistance to interference & multipath
- More stable measurements
- Higher ranging accuracy
- Typical accuracy: ~0.3-1m (improves with multiple channels + antennas)
Phased-Based Ranging (PBR)
- Supports up to 4 antenna paths
- Multiple antennas enable stronger phase analysis
- Delivers more precise distance estimates
