What V2X protocol standards does V2Xcast® follow?

V2Xcast® adheres to industry-standard V2X protocol standards (including candidate standards of C-V2X China and C-V2X Europe), including Dedicated Short Range Communications (DSRC) and Cellular Vehicle-to-Everything (C-V2X). These protocols enable seamless and secure communication between vehicles and infrastructure, facilitating various V2X applications such as vehicle safety, traffic management, and cooperative mobility. By supporting both DSRC and C-V2X, V2Xcast® ensures compatibility and interoperability across different V2X communication systems.

Currently, V2Xcast® has implemented three protocol standards, and all V2X packets over the air are fully compliant with the latest SAE, IEEE, and ETSI standards.

These protocol standards include:
