NXP, BMW Group, and Continental work on new auto Ultra-Wideband (UWB) use cases and standards in CCC

NXP Semiconductors  announced a new automotive UWB IC. The technology is designed to give spatial awareness to UWB-equipped cars, mobiles, and other smart devices, to enable cars to know exactly where users are. 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.

Beyond smart access and remote parking, NXP’s automotive UWB targets other use cases such as:

· Short Range Radar – For life sign detection and easy trunk access

· Smartphone Valet parking – Cars can be “sent” to park autonomously via a smartphone application

· Electric vehicle charging – Autonomous positioning on vehicle charger

· Drive through payment – Localization for secure on-the-go payment

· Car-as-a-Key – Car is enabled to seamlessly access garage door/parking
