Car access & security systems

Bluetooth Channel Sounding technology uses phase-based ranging to enhance accuracy, and the round-trip time of random modulated data packets to enhance security. Bluetooth LE has lower peak-power requirements than ultra-wide band and enables communication and ranging in one technology.

The Bluetooth Channel Sounding feature extends the capabilities of Bluetooth wireless technology-based ranging beyond the limitations of received signal strength indication to help you create high accuracy, low cost and secured ranging designs.

Our Bluetooth LE products enable secure, efficient and reliable communication between vehicles and digital keys.

Through comprehensive development ecosystems and support for the latest Bluetooth LE standards, as well as Car Connectivity Consortium accordance, our products help manufacturers create secure digital key solutions.

Bluetooth LE, with its lower peak power requirements compared to ultra-wide band, enables communication and ranging with a single technology, making it ideal for longer distance ranging.

Our Connection Monitor diagnostic tool captures and analyzes Bluetooth LE packets transmitted between connected devices. It provides detailed information about connection parameters, including signal strength, channel use, connection events and data throughput.

Connection Monitor benefits car access systems by enhancing security, improving reliability, optimizing performance, and aiding in development and testing.

Phone-as-a-key systems require accurate localization of a driver's phone as they approach their vehicle; seamless connection handovers help improve the user experience.

CAN SBCs simplify address encoding for Bluetooth LE connection handovers and triangulation in car access systems.

You can encode the Bluetooth LE address information within the SBC's ID pins and share it with other peer Bluetooth LE connections through the bus communication line.

Bluetooth LE anchors are always in advertising mode until a connection is established. Bluetooth LE needs to be powered on at all times without draining the battery.

Our Bluetooth LE and CAN SBCs work together to reduce overall battery power consumption while keeping the system powered.

These devices allow you to power Bluetooth LE devices with the power supply from the CAN SBC while maintaining a very low quiescent current. The integrated high-efficiency buck helps maintain a small battery current draw at both low (<100µA) and high load currents ( >100mA).
