BMW announces BMW Digital Key Plus with Ultra-Wideband technology coming to the BMW iX.

Munich. As one of the pioneers in the use of a smartphone as a digital vehicle key since 2018, BMW is pressing ahead with the development and popularisation of its BMW Digital Key feature, which is available to iPhone users today. In line with this goal, the premium car manufacturer will introduce the BMW Digital Key Plus, a convenient and secure way to unlock and start your car without taking your iPhone out of your bag or pocket. This latest incarnation of the service is based on Ultra-Wideband (UWB) technology, the technology found on the U1 chip of iPhone. The BMW Digital Key Plus feature will be first launched with the all-electric BMW iX for iPhone. 

Ultra-Wideband technology for enhanced convenience and security. 
The new, additional features enabled by the BMW Digital Key Plus are based on Ultra-Wideband technology. This is a short-range, high-bandwidth digital radio technology that is characterised by an exceptionally precise localisation with the greatest possible security. UWB’s precision also ensures that relay attacks, where the radio signal is jammed or intercepted, are not possible. Apple and BMW have been working closely with the Car Connectivity Consortium (CCC) to establish the Digital Key specification 3.0 for UWB, providing a global standard for the automotive industry.
