Vehicle-to-everything (V2X) communication has become a cornerstone of the automotive industry’s efforts to make cars safer and more aware of their surroundings. It combines once separate efforts around vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I) and vehicle-to-pedestrian (V2P). The aim is to create a roaming network of connected vehicles that can warn of possible collisions, communicate with traffic lights and be alerted to changes in local speed limits or road layouts.
Arguments in favour of dedicated short-range communications (DSRC) are fading as cellular V2X (C-V2X)—which leverages 4G LTE and 5G networks—appears the more complete solution. A recent decision in the US to open up the frequency band once reserved for DSRC to support C-V2X underlines this. But how exactly must new vehicles be equipped to support the growing range of use cases under the C-V2X umbrella?
Inside the vehicle, C-V2X relies primarily on a cellular chipset and
