From Virtual Validation to Certification-Ready V2X Testing
Keysight V2X lab testing solutions help automotive OEMs, Tier-1 suppliers, chipset vendors, and module developers validate connected vehicle systems before deployment. Combining RF, protocol, and application-layer testing with Software-in-the-Loop (SiL), Hardware-in-the-Loop (HiL), and protocol conformance workflows, the portfolio enables comprehensive verification of performance, interoperability, and compliance across DSRC, C-V2X, and emerging NR-V2X technologies. Integrated PNT Xe GNSS simulation provides realistic positioning, timing synchronization, and location-based scenario validation for V2X applications. Reusable ITS application software and test scenarios across SiL and HiL workflows improve test consistency, reduce validation effort, and accelerate the path from development to deployment.

Frequently Asked Questions
Cellular Vehicle-to-Everything (C-V2X) is rapidly gaining traction as the preferred V2X communication technology, leveraging the robust and evolving cellular ecosystem (LTE and 5G). Dedicated Short Range Communication (DSRC) primarily supports direct, peer-to-peer communication (V2V, V2I, V2P) within a range of typically up to 1 km. C-V2X and DSRC are the two primary competing technologies for V2X communication, aiming to enable vehicles to communicate with their surroundings. While they share the same fundamental goal of enhancing road safety and efficiency, they differ significantly in their underlying technical approaches and capabilities. The industry has largely shifted its focus towards C-V2X due to its perceived long-term potential, scalability, and ability to evolve with 5G and beyond, offering a more comprehensive suite of V2X applications.
C-V2X offers several key benefits that are the primary focus of extensive testing and validation efforts. These benefits position C-V2X as a robust and future-proof technology for connected and autonomous vehicles. Testing aims to confirm these advantages under various real-world conditions, including lower packet error rates (PER), enhanced non-line-of-sight (NLOS) performance, robustness to interference, and low latency. Other factors that testing aims to prove include backward compatibility with LTE as well as rigorous protocols for secure communication. Collision Avoidance is paramount. Testing validates that C-V2X can reliably transmit and receive Basic Safety Messages (BSMs) and other alerts in real-time, enabling vehicles to warn drivers (or autonomous systems) about potential hazards.
5G New Radio (NR) is designed to significantly enhance C-V2X capabilities, pushing the boundaries of what's possible in connected and autonomous driving. While LTE-V2X (based on 4G) laid the groundwork for basic safety messages, 5G NR-V2X (Release 16 and beyond) unlocks a new era of advanced use cases. 5G NR is fundamentally designed for ultra-reliable low-latency communication (URLLC), achieving sub-1 millisecond end-to-end latency and extremely high reliability. This is a game-changer for critical safety applications and highly automated driving as it enables near-instantaneous decision-making and reaction times, crucial for collision avoidance, platooning, and cooperative maneuvers. It allows vehicles to respond to events faster than a human driver.
Ensuring compliance in C-V2X testing involves adhering to a complex web of standards from various organizations, covering everything from the fundamental cellular radio technology to the specific messages exchanged and the applications they enable. Here are some key C-V2X standards relevant for testing:
3rd Generation Partnership Project (3GPP): These are the foundational standards for C-V2X, defining the physical layer (PHY), Media Access Control (MAC), and Radio Link Control (RLC) protocols for both the direct communication (PC5 sidelink) and network-assisted communication.
- Release 14 (LTE-V2X): Introduced initial LTE-based C-V2X for basic safety applications (e.g., Basic Safety Messages - BSMs).
- Release 15 (LTE-V2X & initial 5G-V2N): Further enhanced LTE-V2X and introduced the initial specifications for 5G-based V2N (Vehicle-to-Network) communication.
- Release 16 (5G NR-V2X "Phase 1"): A significant leap, introducing 5G New Radio (NR) sidelink for direct V2V/V2I/V2P communication, enabling advanced features like cooperative perception, platooning, and higher throughput.
- Release 17 and 18 (5G NR-V2X "Phase 2" and beyond): Further enhancements for latency, reliability, positioning, and support for even more advanced use cases.
SAE International: SAE standards define the application layer messages and their content, which are agnostic to the underlying communication technology (DSRC or C-V2X).
- SAE J2735: "Dedicated Short Range Communications (DSRC) Message Set Dictionary" defines the syntax and semantics of standard V2X messages like basic safety message (BSM), probe data message (PDM), signal phase and timing (SPaT) message, map data (MAP) message, and roadside safety message (RSM).
- SAE J2945.x series: Addresses various aspects of V2X communication performance requirements and test procedures, including message broadcasting rates, latency, and reception performance.
European Telecommunications Standards Institute (ETSI): ETSI defines cooperative intelligent transport systems (C-ITS) standards primarily for the European market. These cover the communication stack, security, and application messages, often harmonized with 3GPP and ISO.
- ETSI EN 302 665 (ITS-G5 / DSRC): While primarily for DSRC (ITS-G5), ETSI has updated other ITS protocols (e.g., ETSI TR 101 607) to support LTE-V2X as the access layer, particularly for cooperative awareness messages (CAM) and decentralized environmental notification messages (DENM).
- ETSI TS 103 600 series: Specific test specifications for C-V2X conformance.
International Organization for Standardization (ISO): ISO contributes to ITS standards, including aspects of communication, data definitions, and functional safety for automotive systems.
- ISO 21184: Addresses C-ITS application layer messages.
- ISO 26262: Functional safety for road vehicles, while not specific to V2X communication itself, C-V2X systems (being safety-critical) must comply with its principles.
Software-in-the-Loop (SiL) testing validates V2X applications and use cases in a virtual environment before hardware integration. It enables early verification of application behavior, performance, and safety scenarios.
