Bluetooth 6.0 Channel Sounding
Enables sub-meter ranging through phase-based measurements and secure RTT using standard BLE hardware.
Overview
Channel Sounding turns Bluetooth into a reliable ranging technology by measuring phase and timing across multiple frequencies. It delivers low-power, on-device distance estimation in real-world environments without additional radios.
Why This Technology Matters
Channel Sounding provides more accurate and secure ranging than RSSI without the cost or power requirements of UWB. Running on standard BLE chipsets means it scales across consumer, industrial, and IoT devices while delivering consistent performance in complex RF environments.
Why You Need It
If your product needs precise distance measurement for access control, positioning, or proximity sensing, Channel Sounding delivers UWB-level accuracy on existing Bluetooth hardware. It's the most cost-effective path to secure, sub-meter ranging for volume production.
