V2Xcast®

What is V2Xcast® ?

V2X Software Framework

Your Unified Bridge to V2X Complexity

V2Xcast® is a production-grade Software Framework designed to shield developers from the fragmentation of V2X technologies. It acts as the “intelligence layer” that sits between your applications and the underlying hardware.

Whether you are using DSRC or C-V2X, V2Xcast® provides a unified API, ensuring your applications are future-proof, standards-compliant, and ready for global deployment.

Why V2Xcast®?

V2Xcast transforms complexity into capability, delivering tangible benefits that accelerate your V2X development.

Technology Agnostic

Write Once, Deploy Everywhere

Stop choosing between DSRC and C-V2X. V2Xcast® abstracts the physical layer, allowing the same application code to run seamlessly across different radio technologies without rewriting a single line.

Radical Development Efficiency

Months to Weeks

Reduce your time-to-market from months to weeks. With our modular SDK and pre-integrated protocol stacks (WAVE, ITS-G5), you can focus on your core logic while we handle the heavy lifting.

Standards-Ready & Compliant

Global Regulations Made Easy

Navigate global regulations with ease. V2Xcast is built on rigorous international standards (SAE, ETSI, IEEE), ensuring interoperability across diverse vehicle ecosystems and infrastructure.
