3GPP C-V2X device testing for GCF protocol conformance

Rohde & Schwarz, a supplier of test & measurement equipment, has further expanded the capabilities of its R&S CMW500 wideband radio communication tester and R&S SMBV100A GNSS simulator to support Global Certification Forum (GCF) protocol conformance tests for C-V2X device certification.

Utilizing the Qualcomm(R) 9150 C-V2X chipset solution from Qualcomm Technologies, the R&S CMW500 acting as LTE network simulator now allows automakers to test C-V2X direct communications (PC5) according to GCF Work Item 281.

3GPP Release 14 specifies the direct communications specifications for C-V2X 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).

The new R&S CMW-KK550 test package includes the 3GPP Protocol Conformance tests from LTE-V2V GCF Work Item 281 and LTE-V2X GCF Work Item 282. As recently announced, the R&S CMW-KU514 C-V2X software package on the R&S CMW500 is used to verify data transmission and reception over the PC5 interface in ideal, faded and congested channel conditions. Together, both packages enable Rohde & Schwarz to support C-V2X device testing through all protocol layers.

C-V2X device testing is a significant step towards achieving the goal of having fully connected and autonomous vehicles to improve public safety and increase traffic efficiency. C-V2X, including direct communications for safety applications, nicely and synergistically complements network-based communications that deliver telematics services and various use cases for connected infotainment and over-the-air software updates.

"C-V2X PC5 radio technology has quickly advanced to a pre-commercial stage, and 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," said Anton Messmer, Vice President Mobile Radio Testers at Rohde & Schwarz. "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."

The benefits of replacing plain old paper with e-paper displays in automotive assembly plants
Efficiency is at the heart of automation, and that is nowhere more apparent than in the manufacture of automobiles. The Ford Motor Company is widely credited with inventing the moving assembly line, but the concept of moving the assembly, rather than the worker, dates back centuries.
