Bluetooth® Channel Sounding is redefining secure, high-accuracy ranging for automotive access, going far beyond legacy Received Signal Strength Indicator (RSSI)-based proximity. In this video, you will learn how phase-based ranging (PBR) and round-trip time (RTT) deliver more stable, tamper-resistant distance measurements, while also exploring the key innovations in our KW47—NXP's first automotive Bluetooth 6.0 microcontroller (MCU) with channel sounding (CS).
Take a closer look at the KW47.
