To ensure a positive user experience and high performance of the targeted applications, chipmakers, NAD module manufacturers, TCU suppliers, car manufacturers, and certification bodies must conduct comprehensive C-V2X and automotive 5G testing. Rohde & Schwarz test solutions optimize all areas of automotive connectivity and accelerate the transition from the lab to the proving ground and deployment of C-V2X.
Rohde & Schwarz introduces the new R&S CMX500 one-box tester to cover the entire development cycle from chipsets to TCUs and entire automobiles with high-performance 5G automotive measurements that cover RF, protocol and application testing. With the R&S CMX500, you can test all 5G NR deployments including LTE, 5G NR FR1 and FR2 in nonstandalone (NSA) and standalone (SA) modes for both FDD and TDD, all with an effortless setup and outstanding performance. By handling data rates of 10 Gbps and more, the 5G tester reaches its market-leading high performance. With its C-V2X test solution, Rohde & Schwarz will demonstrate that multiple simulated vehicles and the communications between them can be tested in the laboratory and on the proving ground in a precise and repeatable manner. C-V2X applications such as Emergency Brake Warning (EBW) can be verified in realistic and demanding traffic scenarios using the same setup from lab to proving ground using a minimum of test equipment. 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 a tripod and adapter comprise this system. In certain markets, it is required that emergency vehicles be able to generate signals of up to 33 dBm output power. GNSS satellite signals enable the simulated vehicles and test vehicle on the proving ground to be synchronized so complex traffic scenarios can be verified in real time using just one vehicle rather than many. Moreover, the R&S TSMx6 network scanner measures C-V2X PC5 network coverage in the field and ensures proper communication between Road Side Units (RSUs) and between cars (V2V).
As a result of its fine-range and security capabilities, Ultra-Wideband (UWB) technology is well suited for automotive applications such as vehicle access control, ADAS, gesture recognition, and parking assistance. In the lab and on the production line, it is important to test the performance of UWB devices to ensure their compatibility and correct operation. Rohde & Schwarz is a leader in wireless device testing, providing a wide range of UWB test solutions for R&D, certification and production that accurately measure key parameters. In volume production as well as in research and development, the R&S CMP200 radio communication tester is ideal. This tester combines the capabilities of a signal analyzer and a signal generator into one device. The Rohde & Schwarz CMP200, when combined with the company’s WMT software service for automated wireless manufacturing testing, offers a complete solution to conduct and radiated radar measurements in compliance with IEEE 802.15.4a/z specifications for transmitter, receiver, time of flight (ToF) and angle of arrival (AoA).
In the frequency bands L1, L2, L5, Rohde & Schwarz GNSS simulators can generate signals from all operational satellite navigation systems, including GPS, GLONASS, Galileo, BeiDou, SBAS, and QZSS. Satellite orbits can be accurately modeled, including orbit errors and perturbations, as well as other common error sources such as ionospheric and tropospheric distortions and satellite clock errors. A GNSS real-time interface is available for the R&S SMBV100B GNSS simulator. As a result, it is easy to integrate GNSS signals into a HiL test system for the DUT.
In hall 5, booth 5A80, Rohde & Schwarz will display its comprehensive solutions for all trends in the automotive industry at Mobile World Congress 2022 at the Fira Gran Via in Barcelona.
