Cellular-V2X ecosystem – devices supporting 3GPP Release 14 specifications are already commercially available with twenty-five operators involved in trials of LTE or 5G-based C-V2X technologies.
GSA has identified the following cellular-V2X ecosystem status:
Vehicle-to-everything (V2X) technology enables equipped vehicles to communicate with other devices in their surroundings – those carried by pedestrians, other vehicles, or devices embedded in road traffic systems. V2X promises to make the roads safer for all users and more convenient for drivers by enabling a wide range of new safety, information and entertainment applications. The V2X concept encompasses several sub-categories of application, each with their own commonly used names. These are vehicle-to-(transport)-infrastructure (V2I), vehicle-to-pedestrian (V2P), vehicle-to-network (V2N), and vehicle-to-vehicle (V2V).
Over the past couple of years, investment in V2X has been steadily increasing with operators and governmental bodies planning and carrying out trials and developing and building test sites and/or required infrastructure. We have also seen field trials of V2X on public streets in large-scale or city-wide trials such as in China, Europe, South Korea and the USA.
Two technologies have been in the running to be deployed in V2X systems. The first to emerge was WiFi-based 802.11p. Versions of this technology have been lined up to underpin traffic safety systems in the USA (using DSRC) and Europe (under the auspices of the Intelligent Traffic Systems [ITS] initiative) for some time. More recently however, it has become clear that Cellular-V2X systems using 3GPP-based LTE and 5G have a lot more to offer, and proponents argue it is better placed than 802.11p to meet the communications needs of V2X systems.
