The formation of a new working group to develop standards for ultra wideband (UWB) connectivity has marked a significant milestone in the convergence of the automotive and consumer tech industries. As a result, digital keys, which have already made waves in the automotive market, are expected to become even more popular and ubiquitous in the near future. This development comes as a result of the Car Connectivity Consortium (CCC) and FiRa Consortium, two prominent bodies in the industry, joining forces to establish the Joint Ultra-wideband (UWB) MAC PHY Working Group (JUMPWG) with a primary focus on ensuring long-term interoperability and scalability of advanced UWB technology.
The CCC, which counts major car companies, Apple, Samsung, and Xiaomi among its members, has been at the forefront of driving innovative connectivity solutions such as the CCC Digital Key. On the other hand, the FiRa Consortium has been championing UWB technology with the support of tech giants like Apple, Google, Cisco, Samsung, and Qualcomm. By bringing together these influential bodies, the impact of this collaboration on the future of UWB technology cannot be overstated.
Alysia Johnson, President of the CCC, expressed optimism about the working group’s potential to encourage broader adoption of UWB technology for secure and accurate ranging for vehicle access. Furthermore, the group is poised to address key concerns such as cybersecurity and the misuse of technology for nefarious purposes, which is a critical consideration as more and more vehicles integrate digital key solutions.
A key figure in this new working group is Jinjing Jiang, a wireless systems engineer at Apple, who is set to lead the efforts in deliberating over the necessary standards that will be embraced by both smartphone and car manufacturers. The ultimate goal is to create a cohesive framework that ensures the safety and reliability of UWB-based digital key systems, thereby minimizing the potential threat of cybersecurity breaches and illicit use of the technology.

The development of digital keys leveraging UWB technology presents a leap forward in the realm of smart connectivity solutions. These keys make use of a combination of UWB and near-field communication (NFC), along with low-energy Bluetooth, to facilitate seamless communication between smartphones and vehicles. This innovation allows for features like unlocking and starting cars without requiring users to physically handle their keys or even take their phones out of their pockets.
In a broader context, it has been an ongoing journey to bring UWB technology to digital car keys. Brands like BMW, Audi, and Ford have been working on integrating digital key solutions, with BMW even releasing its own digital key for various smartphone devices. However, these earlier incarnations of the technology predominantly relied on NFC, requiring users to hold their phone next to the handle of the driver’s door to unlock the vehicle.
Beyond the automotive realm, UWB has also been gaining traction in consumer devices, with Apple leveraging the technology in its iPhone, Apple Watch, and AirTag. This has enabled more precise location awareness, enhancing features such as Precision Finding for the AirTag. As this technology continues to evolve, it is poised to transform the way users interact with their devices and vehicles, marking a significant shift towards a more seamless and intuitive user experience.
In summary, the formation of the Joint Ultra-wideband (UWB) MAC PHY Working Group (JUMPWG) represents a pivotal moment in the ongoing development of digital key solutions utilizing UWB technology. With influential industry players coming together to define industry-wide standards, the stage is set for digital keys to become more widespread and increasingly integrated into the daily lives of consumers. As the working group progresses, it is anticipated that the collaborative efforts will pave the way for a new era of secure, reliable, and innovative smart connectivity solutions.
