22 The Future of Automotive Introduction Wireless location/distance sensing and secure communications are the backbone of the latest convenience, performance, security, and safety features of emerging automotive systems from consumer to fleet vehicles. Autonomous driving and augmented driver assistance features are increasingly in demand. However, there are limitations to familiar short-range relative location sensing technologies for automotive applications, of which the most significant are: • The latency/location update rate • Location accuracy, and • Security of the accompanying communication A recently reinvented technology, Ultra-Wideband (UWB), is poised to substantially enhance short-range relative location sensing, secure communication between vehicles, and develop many previously infeasible advanced automotive features. A Far Superior Automobile Using UWB Technology Jean-Jacques DeLisle for Mouser Electronics What is UWB? Ultra-Wideband (UWB) is a wireless standard based on IEEE 802.15.4z that is designed to provide micro-location and secure communication. UWB is also designed to be superior to many of the existing wireless standards regarding reliability, location accuracy, location latency/update rate, and security while being affordable and compact. Additionally, due to the nature of UWB's physical layer protocol, UWB communications and location sensing are highly immune to multi-path and interference, all while using minimum energy (Figure 1). Figure 1: UWB in a nutshell. (Source: Qorvo) Imagine a distance/location and communication wireless technology that is both small and cost-effective while delivering centimeter accuracy in real-time. This is Ultra-Wideband (UWB).
