Testing challenges for V2X Devices
This article explores the status of intelligent transport systems standardisation worldwide, with a special focus on the different testing categories and solutions for wireless access in vehicular environments.

Its VSG (Vector Signal Generator) can generate signals from 10 MHz to 6 GHz with 160 MHz bandwidth. Similarly, the VSA (Vector Signal Analyser) can analyse signals within the same frequency range and bandwidth, while the in-built CPU and memory ensures fast capture and analysis of signals. The software provided for manual/R&D testing (Figure 5) and the fully automated software for production testing minimizes time to production.

Conclusion

A large number of car manufacturers, system board makers and service providers in the automotive ecosystem have announced formal plans to develop autonomous driving technology, and it is becoming clear that telecommunications between vehicles will play an important role in the future, changing the concept of “intelligent car” towards “autonomous car”. Trials are currently being conducted in America, Asia and Europe based on IEEE 802.11p or 3GPP Cellular-V2X.

V2X test solutions are now available that can be used for system validation and performance benchmarking up to production line testing, with significant reductions in costs, measurement uncertainty and the time associated with extensive field testing. It is now possible to analyse and replicate real-world traffic scenarios in the laboratory, with full support for Europe, US and Japan protocol stacks. These RF and protocol conformance test solutions are ideal for in-house pre-conformance testing. In production or final device verification, a multi-standard solution for production provides fast and low-cost device testing according to international standards.

Vehicular communications are shifting from one-way to any-way, and the automotive industry must deliver advanced connectivity services to meet customer demand. With a complete range of RF and wireless testing solutions, users can now design and implement sophisticated vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2X) communications services.
