As a leading global provider of wireless modules and solutions, Shenzhen RF-Star Technology Co., Ltd. (RF-star) was honored to be interviewed by Lori Lee, APAC Marketing Director of Bluetooth SIG. During the interview, RF-star’s Marketing Manager, Ms. Qianqian Wen, shared valuable insights into the market trends of digital keys and highlighted the pivotal role of Bluetooth technology in the intelligent vehicle ecosystem. Furthermore, we are eagerly anticipating the upcoming release of the Bluetooth Channel Sounding feature, which we believe will significantly enhance the performance of digital key solutions.

Bluetooth SIG's Interview with RF-star

In recent years, the new energy vehicle market has grown rapidly. How do you view the importance of digital keys and market trends?

The digital key serves as the first connection point for users to experience intelligent cars. At this connection point, security, reliability, convenience, and interactive comfort are all indispensable. The success of the digital key experience design is crucial for car user evaluations and plays a key role in deepening the connection with users. With the maturity of technologies like Bluetooth® Low Energy (LE), near-field communication (NFC), and ultra wide band (UWB), digital keys are entering a period of rapid growth, and integrated solutions will become the market mainstream.

What are the technological advantages of Bluetooth technology in digital key solutions?

RF-star chose Bluetooth® technology to develop car digital key solutions, primarily because of its low power consumption, high reliability, and broad device compatibility. Bluetooth technology provides stable wireless connections and supports various smart devices like smartphones and smartwatches, enabling users to remotely control vehicles through these devices for keyless entry, starting, and other functions. Additionally, Bluetooth technology’s low power consumption helps reduce operating costs.

RF-star also values Bluetooth technology’s iterative capabilities. For example, the upcoming channel sounding feature improves the positioning accuracy of Bluetooth Digital Key solutions and protects the system from relay hijacking. It may become a cost-effective preferred technology in the digital key domain in the future.

With the upcoming release of the Bluetooth Channel Sounding feature, what positive impacts do you foresee for digital key solutions? How can it address existing challenges and further drive the development of intelligent vehicles?

The release of Bluetooth® Channel Sounding is expected to enhance the performance of digital key solutions, particularly in precise positioning and security. This feature may address positioning challenges in complex environments, improve vehicle identification accuracy based on user’s position, and enhance Bluetooth Digital Key security by preventing relay hijacking. The overall cost effectiveness and rich ecosystem foundation of this new feature may further drive the development of Bluetooth technology in the Internet of Vehicles field, supporting higher levels of autonomous driving technology.

Does RF-star have any further development plans for Bluetooth Digital Key solutions?

With technology evolving and market demands iterating, RF-star will continue innovating at several levels:

1. Iterating Bluetooth Digital Key experiences based on channel sounding technology
