Bluetooth 6.0 Introduces Channel Sounding
- Bluetooth Core Specification 6.0 adds six major features, with channel sounding as the headline capability.
- Channel sounding enables centimeter-level ranging on standard Bluetooth connected devices.
Channel Sounding Is Connected Distance-Only
- Channel sounding is connection-oriented and measures distance only, not direction.
- It complements presence, RSSI, and direction-finding as part of Bluetooth's positioning portfolio.
Verify Chip And Firmware Support Early
- Check your Bluetooth SoC vendor for channel sounding support before designing products.
- Expect some devices may need updated chips or firmware to enable the new physical-layer capabilities.
