Ultra-wideband chip turning smartphones into car keys

For the first time, smartphone-based car access offers the same level of convenience as key fobs. Users can open and start cars, while leaving their phones in their pockets or bags, and enjoy secure remote parking via smartphone. Furthermore, the new UWB IC brings maximum level of protection against car theft through relay attacks.

In conjunction with the launch of the IC, NXP, BMW Group, Continental and others are jointly working on UWB implementations through the Car Connectivity Consortium (CCC) and IEEE to ensure the best customer experiences at the intersection of the vehicle, mobile, and consumer devices. These standardisation efforts aim to enable a global standard for handsfree smart access and other automotive localisation use cases based on UWB.

“Today, the smartphone plays a central role in the digital lifestyle. We are convinced that the smartphone-based comfort access is just the beginning of a series of innovative vehicle-related UWB use cases,” said Dr Olaf Müller, Head of Development Digital Access Functions, BMW Group.

“Continental is at the forefront in delivering secure localisation platforms that will create leading applications that catch the imagination of the power user generation,” added Philippe Fournet-Fayat, Director at Continental for Car Access Systems. “To deliver new use cases, such as smartphone access and remote parking requires the ultra-precise real-time localisation capabilities of UWB.”

Markus Staeblein, Vice President and General Manager of Secure Car Access at NXP, said: “The opportunities that exist in the web of mobility and automotive are vast. As a leading semiconductor manufacturer in these segments, we have the ambition to tap these and bring more seamless and secure mobility experiences to users. We are pleased to jointly work on the required interoperability and standardisation for UWB with BMW Group, Continental and other CCC members.”

The NXP NCJ29D5 is the first of a new generation of UWB ICs designed specifically for the demands of the global automotive industry. Together, with NXP connectivity and security solutions, such as Bluetooth, Near Field Communication, and Secure Element (SE), this technology enables true secure handsfree smart access supporting the car connectivity standardisation.
