Channel Sounding with KW47 Wireless Automotive MCU

Channel Sounding with KW47 Wireless Automotive MCU

Bluetooth Channel Sounding is transforming secure, high-accuracy ranging for automotive access, going far beyond legacy RSSI proximity. In this video, you'll learn how phase-based ranging (PBR) and round-trip time (RTT) enable more stable, tamper-resistant distance measurements, and highlights the key innovations in our KW47, NXP's first automotive Bluetooth 6.0 MCU with Channel Sounding.

Take a deeper look into KW47.
