Modular architecture for enhanced vehicle access with Bluetooth® Channel Sounding

Martin Cuvelier from NXP Semiconductor examines how Bluetooth® Low Energy integrates into a modular, multi‑anchor embedded system architecture to enable secure vehicle access and precise user positioning. It highlights advanced Bluetooth LE capabilities—such as channel sounding for accurate ranging and seamless handover between anchors over CAN or Ethernet—to improve robustness, security, and power efficiency. The session also explores real‑world vehicle access scenarios using trilateration and adaptive mechanisms, with an eye toward extensibility to UWB for CCC‑compliant automotive implementations.
