CAN Antenna
Product Introduction

The potential of seamless entry technology in enhancing the user experience of car access systems is limitless. Users can walk towards the car while unlocking it with their smartphone key. The car can automatically adapt to user preferences, such as the positions of mirrors, seats, steering wheel, and head-up display, based on custom digital profiles. With a car access system based on CAN communication technology, the car can also use various secure ranging and positioning technologies to locate authorized phones inside the car, adding an extra layer of security before unlocking the doors and starting the car. In addition, users can create digital keys for friends and family, temporary digital keys for valet parking attendants, making car sharing even more convenient.


This solution is based on TI CC2640R2F, CC2640R2F-Q1, CC2642R-Q1 automotive Bluetooth 5.0 chips and NFC technology, and works on Android 8.0 and above or iOS 5.0 and above. The smartphone's built-in master-slave mode works with the slave devices and CAN scanning antennas installed in the car to achieve seamless recognition and positioning. This function becomes available when the user completes user registration and vehicle ownership verification using the app, and the smartphone's Bluetooth function is turned on, without the need to open the app.
