14 The Future of Automotive The Foundation for Vehicular Connectivity In order for the truly autonomous vehicle to navigate without human intervention, data of all types must be shared continuously and in real time with other vehicles and the surrounding infrastructure. This will happen using vehicle-to-everything (V2X) communication systems. V2X encompasses vehicle-to- vehicle (V2V), vehicle-to-infrastructure (V2I), vehicle- to-network (V2N) and vehicle-to-pedestrian (V2P) communications. V2X is based on 5.9GHz dedicated, short-range communications and is designed for fast-moving objects. It makes it possible to establish a reliable radio link, even in non-line-of-sight conditions. This trusted link enables drivers to be aware of hazards ahead, reducing potential automotive collisions, fatalities, and injuries. Further, V2X will enhance global transportation efficiency and reduce CO2 emissions by warning of upcoming traffic congestion and suggesting alternative routes—with an added benefit of reducing vehicle maintenance. Realizing the full potential of autonomous vehicles is complicated by the fact that V2X can be either C-V2X (cellular vehicle-to-everything), which uses cellular technology to create direct communication links, or DSRC (dedicated short- range communications), which is based on the IEEE 802.11p standard and was at one time the only V2X technology available. Different auto manufacturers and countries are supporting one or the other standard; however, both utilize the same spectrum to solve the same problem, and they can co-exist. Understanding Connectivity Technologies In order to better understand coexistence challenges, we must look at the technologies involved in vehicular connectivity and how they function (Figure 1). Because each has its own characteristics, they must interact without degrading the performance of the others. How to Mitigate Spectrum Challenges Associated with V2X Ali Bawangaonwala Senior Marketing Manager, Qorvo Executive Summary Wi-Fi and 5G are recognized as enablers of autonomous vehicles. The challenge lies in how these technologies work together and co-exist—despite spectrum interference that can adversely impact vehicle operation and passenger safety. This paper discusses the technologies that support vehicular connectivity and how high-selectivity filter solutions address V2X coexistence with Wi-Fi to enable vehicular communications.
