Bluetooth® Channel Sounding is a new secure, fine-ranging capability that promises to enhance the convenience, safety, and security of many Bluetooth connected devices. From increasing the security of digital keys to improving the performance of Find My solutions, Bluetooth® Channel Sounding will enhance our connection with our devices, one another, and the world around us.
“Extending an already rich ecosystem, the Bluetooth® Channel Sounding standard enables connected devices to more precisely and securely locate each other, paving the way for the design of new low-cost, energy-efficient, location-aware solutions,” said Kyle Golsch, senior RF system engineer at DENSO. “It also has the potential to provide a more secure and convenient user experience for automotive digital key solutions and we look forward to leveraging this technology inside and outside of automotive areas to enable more seamless user experiences for all.”
How Bluetooth Channel Sounding Works
Bluetooth® 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.
