Integrated Test Platform to Target Chinese Market for V2X-based Applications

Rohde & Schwarz, in collaboration with VectorSavari and Quectel has successfully presented an application layer test solution for 3GPP C-V2X Release 14, specifically aimed at the growing Chinese market. Cellular vehicle-to-everything (C-V2X) is an LTE-based technology that allows vehicles to communicate wirelessly with other vehicles, smart infrastructure and pedestrians. 

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

The R&S CMW500 radio communication tester and the R&S SMBV100B vector signal generator are 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.
