To conduct its onboard unit (OBU)/roadside unit (RSU) RF performance testing, the China Automotive Technology and Research Center (CATARC) has chosen Rohde & Schwarz’s RF C-V2X automated test system.

C-V2X is of growing importance to vehicle manufacturers and suppliers, and the creation of the appropriate standards and testing procedures to ensure compliance has become the key to the adoption of the technology.

Vehicle OEMs and Tier 1 component suppliers need a standard system to support and guide the development and research of their C-V2X products and function of the overall system. Additionally, testing service companies and authorities need to carry out considerable validation and certification work in accordance with the government and industry regulatory requirements.

In China, the GB/T “Technical Requirements for Vehicle Information Interaction System Based on LTE-V2X Direct Communication” is the cornerstone of the Internet of Vehicles standard system, which is being formulated by the country’s Auto Standards Committee. This includes the RF performance requirements and test methods of Internet of Vehicles products.

The Rohde & Schwarz RF C-V2X automated test system was selected by CATARC because of its comprehensive coverage of Internet of Vehicles C-V2X RF test cases and overall system standard assessment capability. With the support of CATARC, Rohde & Schwarz conducted joint debugging with major C-V2X chip manufacturers and solved the many challenges of C-V2X RF testing. The system is capable of complete test project coverage, a high degree of automation and flexible instrument configuration, which meets the requirements of the automotive industry for C-V2X radio frequency testing.

The system integrates the R&S CMW wideband radio communication tester and the R&S SMBV100B vector signal generator, which supports the C-V2X protocol, data consistency and electromagnetic compatibility test cases required. It is also possible to upgrade the hardware-in-the-loop test system for the Internet of Vehicles traffic scenario.
