C-V2X Test Solution supporting China's ITS Standard

30 August 2019 - Rohde & Schwarz working together with Vector, Savari and Quectel presented a test solution for C V2X at the MWC Shanghai 2019. The integrated setup is based on the R&S CMW500 wideband radio communication tester and the R&S SMBV100A/B GNSS simulator by Rohde & Schwarz, together with the comprehensive simulation tool CANoe.Car2x by Vector.

The setup utilizes Savari's proven C-V2X middleware and a testing module by Quectel, providing an end-to-end, upper layers testing solution for the C-V2X technology in compliance with all necessary regional requirements including China's ITS standard GB/T 31024.

This integrated test platform was presented at the Mobile World Congress in Shanghai 2019 and is a complete solution for simulation development and testing of all V2X-based applications.

The presented C-V2X test solution consists of a device under test C-V2X module AG15 provided by Quectel, running Savari's MobiWAVE(R) V2X Software Stack and receiving the ITS messages provided by the R&S CMW500 wideband radio communication tester and the GPS signal by R&S SMBV100B vector signal generator. The R&S CMW500 uses a C-V2X software package needed to simulate the Physical- and MAC-layer in order to transmit and receive data over the PC5 radio interface. Vector's software environment for V2X application testing, CANoe .Car2x, is used to create and simulate detailed traffic situations for the verification of C-V2X connectivity. Savari's C-V2X middleware helps demonstrate the outstanding versatility and performance of the R&S CMW500, while presenting a variety of applications ideal for 3GPP LTE-V2X PC5 interoperability testing. It offers the full support of the necessary standards and specifications required for proper functioning in China's networks, such as the GB/T 31024 standard for the next generation of cooperative intelligent transport systems.

This is the only test solution available that covers all layers, from the physical layer and the RF measurements, the protocol layer and the protocol conformance tests, up to the application layer with the fully integrated ITS stack.

This setup presents an end-to-end solution for testing all related functionalities of C-V2X. This includes both device-to device communication - between a vehicle and another vehicle (V2V), a vehicle and a pedestrian (V2P), a vehicle and the surrounding road infrastructure (V2I), and device-to-network (V2N) type of communication.

Anton Messmer, VP Mobile Radio Testers at Rohde & Schwarz, says, "With this successful end-to-end verification, we are happy to present our solutions to the quickly developing Chinese market. Rohde & Schwarz, together with Vector, Savari and Quectel, is dedicated to providing top-of-the-class product solutions that can support the automotive industry to reduce the time to market, while making sure that safety always remains a top priority."

Ravi Puvvala, CEO of Savari, says, "As a leading player in the V2X market, we were more than happy to provide our expertise and collaborate with Rohde & Schwarz, Vector and Quectel. The combination of our technologies resulted in a unique testing solution that can help companies speed up the production of their C-V2X systems. In quickly expanding markets, with China being a prime example, this testing solution will immensely simplify the process of C-V2X based product creation and deployment."

The R&S CMW500 radio communication tester and the R&S SMBV100B vector signal generator by Rohde & Schwarz present the perfect solution for C-V2X testing. In combination with the Vector CANoe .Car2x software solution, engineers can easily verify critical end-to-end safety related V2X scenarios in a lab environment.
