Automotive 5G and C-V2X test solutions for performance and reliability

Comprehensive C-V2X and automotive 5G testing is crucial for chipset developers, NAD module makers, TCU suppliers, car manufacturers and certification bodies to provide a positive end-user experience and high performance of the targeted applications. Test solutions from Rohde & Schwarz ensure optimisation of all aspects of automotive connectivity and speed the progress of C-V2X from lab to proving ground and deployment.

The company presents high-performance 5G automotive measurements with comprehensive test coverage, including RF, protocol and application testing using its new R&S CMX500 one-box tester covering the complete development cycle from chipsets to TCUs and whole vehicles. The device delivers extensive testing capability, supporting all 5G NR deployments covering LTE, 5G NR FR1 and FR2 in NSA and SA mode, for FDD and TDD with an effortless setup and excellent performance. The 5G tester reaches its market-leading high performance with its capacity to handle data rates of 10Gbps and beyond.

At MWC Barcelona 2022, the company will show a C-V2X test solution that lets traffic scenarios comprising multiple simulated vehicles and the communications between them to be tested in the laboratory and the proving ground in a precise and repeatable way. This allows the correct operation of C-V2X applications such as Emergency Brake Warning in realistic and demanding traffic scenarios to be verified utilising a minimum of test equipment and the same test setup from lab to proving ground. The system includes an R&S CMW500 wideband radio communication tester, an R&S SMBV100B vector signal generator (lab only), an R&S BBA150 amplifier and an R&S HF918 antenna with tripod and adapter. It can easily generate signals with up to 33 dBm output power, which is required for emergency vehicles in specific markets. Synchronisation of the simulated vehicles and the test vehicle on the proving ground with GNSS satellite signals enables verification of complex traffic scenarios in real-time using only one test vehicle rather than many. Also, the R&S TSMx6 network scanner enables C-V2X PC5 network coverage measurements in the field and ensures the proper communication of Road Side Units and between cars.

GNSS simulators from the company generate signals for all operational satellite-based navigation systems, including GPS, GLONASS, Galileo, BeiDou, SBAS and QZSS in the frequency bands L1, L2 and L5. Simulation abilities include correct modelling of satellite orbits, including orbit errors and perturbations, and other typical error causes like ionospheric and tropospheric effects and satellite clock errors. The R&S SMBV100B GNSS simulator can offer a GNSS real-time interface option. This allows easy integration into a HiL test system to provide GNSS signals for the DUT.
