Rohde & Schwarz has successfully implemented a number of cellular vehicle-to-everything (C-V2X) direct communications signaling tests to verify end-to-end communications, performance and conformity to standards. Working with the Qualcomm 9150 C-V2X chipset solution, Rohde & Schwarz demonstrated testing and full end-to-end communications between simulated vehicles in the context of a road-side emergency situation.
The R&S CMW-KU514 C-V2X verification scenarios option on the R&S CMW500 is used to demonstrate simulation of an ITS message transfer from one vehicle to another during emergency braking. C-V2X allows vehicles to communicate directly with each other (V2V), with pedestrians (V2P) and with roadway infrastructures (V2I) without a mobile cellular subscription or network assistance while operating in bands 46D and 47 for the 5.8 GHz/5.9 GHz harmonized ITS spectrum.
At Mobile World Congress 2018 in Barcelona, Rohde & Schwarz showcased their CMW500 wideband radio communication tester and a pre-commercial Qualcomm 9150 C-V2X chipset solution that implements 3GPP Release 14 cellular vehicle-to-everything (C-V2X) direct communications technology. Rohde & Schwarz, working with companies including Qualcomm Technologies, aims to support an official global certification scheme based on 3GPP standardized conformance tests selected by the Global Certification Forum (GCF) in preparation of commercialization.
