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.

Conformance and regulatory testing

V2X devices are designed to communicate with other elements of the road, with other wireless devices coexisting in the same or adjacent spectrum, and most importantly with each other. Device manufacturers therefore need to agreed and conform to a standard set of standards and regulations.

In Europe and the US, the protocol stacks have the same common blocks or functionality, but have completely different implementation (Figure 3).

The main characteristic of conformance test systems is their complexity, but these systems are constantly being updated as the technology evolves. One future use case could be cellular V2X. Under these circumstances, a test solution that does not rely on commercial “golden radio” solutions for the access layers offers benefits as standards are updated or move towards a different radio access technology.
