Rohde & Schwarz, in collaboration with Vector, Savari, and Quectel, announced the successful presentation of an application layer test solution for 3GPP C-V2X Release 14, specifically aimed at the growing Chinese market.
The C-V2X test solution consists of a device-under-test C-V2X module AG15 provided by Quectel, running Savari's MobiWAVE V2X Software Stack and receiving 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 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 to verify C-V2X connectivity. Savari's C-V2X middleware helps demonstrate the 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.
The solution is claimed to be 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.
The setup presents an end-to-end solution for testing all related functionalities of C-V2X. This includes device-to-device communication as well as 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) communication.
Anton Messmer, VP mobile radio testers at Rohde & Schwarz, said, "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, noted, "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."
