Bookmark or Share- Bluetooth® Channel Sounding: A Technical OverviewThis paper provides a detailed technical overview of Bluetooth® Channel Sounding, a secure fine ranging feature that enables true distance awareness between two Bluetooth devices.
- Bluetooth's New Era: The Role Of Channel Sounding And Adaptable Testing ...Bluetooth Channel Sounding vastly improves the accuracy and security of distance measurements in Bluetooth LE. By leveraging a combination of phase-based ranging and time-of-flight measurements, it can significantly increase distance measurement accuracy down to tens of centimeters.
- Bluetooth® Channel Sounding | Bluetooth® Technology WebsiteBluetooth ® Channel Sounding leverages phase-based ranging (PBR) to achieve precise distance measurements between two devices. In PBR, an initiator device sends a signal to a reflector device, which returns the signal. This process is repeated across multiple frequencies.
- Bluetooth Channel Sounding: - Bluetooth Technology WebsiteBluetooth® Channel Sounding uses two proven ranging methods, phase-based ranging (PBR) and round-trip time (RTT), to enable secure, fine ranging between two Bluetooth connected devices.
- High Accuracy, Low Cost, Secure Ranging with Bluetooth Channel SoundingThe Bluetooth channel sounding feature uses phase-based ranging across multiple frequency tones to perform high accuracy distance measurement and round-trip time of flight measurements to mitigate man-in-the-middle based security threats against distance manipulation.
