V2X (Vehicle-to-X)

Test, Measurement, and Simulation of all V2X aspects

The possibility of the direct communication between all traffic participants (V2X – Vehicle-to-Anything) adds a new quality of information to the vehicle. The exchange of the current status can occur between vehicles, pedestrians, motorbikes, bicycles, and others as well as with infrastructure such as traffic signs, traffic lights and so on. 
S.E.A. provides specific V2X test products and brings the required V2X technologies into the test systems.

Depending on the goal of the customer, V2X communication requires in-depth knowledge of a wide field of technologies including RF, protocols, standards, and applications.

In order to provide tailored solutions for the different requirements of V2X test systems,

S.E.A. has developed a set of different communication products based on National Instruments hardware and software technologies.

The 802.11p stack is implemented based on NI Software Defined Radios to handle all manipulation required. A LTE-V implementation will also be available.

Some features of the products include:

  • Communication on protocol level by different global standards
  • Failure injection and deep monitoring on protocol level for validation and verification
  • Precise replay of V2X messages
  • Tight synchronization of V2X communication in open loop and HiL V2X and ADAS test systems
  • RF-Compliance measurements for different standards
  • Modularity by providing the same software interface for all V2X products (LabVIEW and C)


Full lifecycle solutions & products


These products are also the base of the integrated test solutions which combine the required signal sources to a unique easy to configure system.

Your benefits

  • Full coverage of V2X aspects by modular solutions
  • Application oriented integration with other signals
  • Future safe based on standard National Instruments off-the shelf components
  • Flexible and customizable through use of Software Defined Radio technology
  • Support of major global standards in all layers


V2X is based on the information exchange between different traffic participants via wireless communication methods. In order to ensure the accurate exchange and interpretation of the information sent between all traffic objects the physical transmission layer and message structure/content  is standardized. Every participant therefore must prove its conformance in the RF-environment, as well as the compliance on the different protocol layers.

The standardization has been developed over the last 20 years and is specifically defined for the different regions of the world. In the EU the standardization is driven by ETSI, while in the US SAE and IEEE standards define V2X on the different layers.

For physical RF-transmission, standards such as 802.11p and alternatively LTE-V are used in regulated frequency bands. In the US the higher layers are defined by IEEE 1609.x, SAE J2735 and SAE J2945 (WAVE). In Europe the overall concept is named ITS-G5 and is mainly defined by ETSI EN302 665, ETSI EN 303 663. Japan is defined by ARIB and ISO standards.

For ADAS applications the information available to the vehicle by V2X is

  • supporting the driver in order to increase safety and quality of driving
  • crucial for autonomous driving as additional data complementing other sensors with specific availability and traffic focused information
