Munich-based test equipment supplier Rohde & Schwarz has updated its CMW500 radio tester and SMBV100A GNSS simulator to support cellular vehicle-to-everything (C-V2X) device certification. It is the first test equipment vendor to offer a “comprehensive” C-V2X test suite for the car industry, it said.
3GPP Release 14 specifies the direct communications specifications for C-V2X direct communications (PC5), which enables vehicle-to-vehicle (V2V), vehicle-to-pedestrian (V2P) and vehicle-to-infrastructure (V2I) safety applications, and does so without a mobile cellular subscription or network assistance and operates in ITS bands 46D (5.8 GHz) and 47 (5.9 GHz).
Rohde & Schwarz’s updated CMW500 tester, running Qualcomm’s 9150 C-V2X chipset, allows automakers to run Global Certification Forum (GCF) protocol conformance tests for C-V2X PC5 device certification.
Anton Messmer, vice president for mobile radio testers at Rohde & Schwarz said: “C-V2X PC5 radio technology has quickly advanced to a pre-commercial stage. Rohde & Schwarz is pleased to be the first test equipment vendor to offer a comprehensive C-V2X test suite. The automobile industry can now verify functionality and performance of C-V2X devices, as well as start device testing as per 3GPP protocol conformance tests.”
Rohde & Schwarz said C-V2X device testing is crucial for fully connected and autonomous vehicles to improve public safety and increase traffic efficiency. C-V2X, including direct communications for safety applications, complements network-based communications that deliver telematics services and various use cases for connected infotainment and over-the-air software updates.
Messmer said: “This expanded capability complements our support for European eCall and shows our long-standing support for automotive applications. Rohde & Schwarz is committed to providing industry-leading test platforms for C-V2X device performance testing and GCF device certification.”
