C-V2X is one of the two technologies developed for vehicle-to-vehicle (V2V) and V2X communication with the goal to enhance road safety and enable smart transportation systems. The other contender in this promising market is DSRC, with the IEEE 802.11p radio standard. This technology is already in series production at Volkswagen. The Golf VIII compact car is already equipped with this technology (in VW’s marketing slang, this feature is called WLANp). Volkswagen plans to equip most of its future vehicles (including brands like Skoda or Seat) with WLANp; however, since C-V2X also includes a link to the cellular infrastructure, many market observers believe that in the long run, C-V2X will prevail.
Developed by the 3rd Generation Partnership Project (3GPP) organization, C-V2X establishes the foundation to support safety use-cases with a path for integration into next generation 5G technologies, while tapping into the broader 3GPP ecosystem to drive wider adoption.
A new European Standard (EN) defining the use of C-V2X as an access layer technology for Intelligent Transportation System (ITS) devices was recently approved through the European Telecommunication Standardization Institute (ETSI). In addition, all the ETSI standards and specifications that define other ITS protocols above the access layer have been updated to support utilization of C-V2X as the underlying access layer. These standards and specifications have been included in the ETSI ITS Release 1 specification set and provide the basis for development of interoperable C-V2X ITS implementations and devices from multiple vendors.
Which brings us back to the products certified according to the European Radio Equipment Directive. They are made by Commsignia, Ficosa, Kapsch, and Savari, and they all are based on Qualcomm’s 9150 platform.
C-V2X continues to gain global momentum. In the United States, recent field tests have shown adequate range, reliability, and performance of C-V2X direct communications, in addition to the ability for C-V2X to work well in congested environments. In Europe, recent plugtests organized by ETSI and 5GAA demonstrated multi-vendor interoperability, while multiple corridor projects are being planned to test the technology on the road, starting from 5G-CARMEN and Concorda projects.
