Secure localization with Bluetooth® Channel Sounding for localization and smart keys in automotive systems

Sindhu Sondur from OpenSynergy GmbH examines how Bluetooth® Channel Sounding transforms Bluetooth LE into a secure platform for precise, real‑time localization. It explains the underlying distance‑measurement methods—Phase‑Based Ranging and Round‑Trip Timing—and how controller, HCI, and antenna configurations enable accurate ranging, presence detection, and direction finding. Using an automotive keyless access system as an example, the talk analyzes the security characteristics, interfaces, and design principles required for secure Bluetooth LE localization across automotive, industrial, and smart access applications.
