BT Antenna

Product Introduction

The potential of low-energy Bluetooth technology in enhancing the user experience of car access systems is limitless. Users can walk towards their vehicle while using their smartphone key to unlock it. The car can automatically adapt to the user's preference settings, such as mirror, seat, steering wheel, and head-up display positions, based on custom digital profiles. With a car access system based on low-energy Bluetooth technology, the car can also use various secure ranging and positioning techniques to locate authorized phones inside the car, adding an extra layer of security before unlocking the doors and starting the engine. In addition, users can create digital keys for friends and family, or temporary digital keys for valet parking attendants, making car sharing more convenient.

This solution is developed based on TI CC2640R2F, CC2640R2F-Q1, CC2642R-Q1 automotive Bluetooth 5.0 chips and technologies, and works with Android 8.0 and above or iOS 5.0 and above on smartphones. The built-in BLE master-slave mode in the smartphone, along with the BLE slave device and BLE scanning antenna placed on the car body, realize seamless recognition and positioning. This function allows for seamless recognition without the need to launch the app after the user has completed user registration and vehicle ownership verification via the app and has turned on the phone's Bluetooth function.
