Connected vehicle technology company Autotalks has used Keysight Technologies‘ PathWave V2X solutions to verify the TEKTON3 vehicle-to-everything (V2X) system-on-a-chip (SoC) against the physical layer specifications of the 3GPP 5G New Radio (NR) Release 16 (Rel-16) Sidelink standards.
Sidelink, a feature of 3GPP Rel-16, facilitates direct communication between devices and supports next-generation 5G NR V2X Day 2 use cases, enhancing road safety through cooperative perception among vehicles.
Day 2 use cases like cooperative perception rely on robust physical layer communication, which defines the signals and channels crucial for stable and feature-rich communication. To ensure reliable and interference-free communication, physical layer testing is imperative during the SoC design and verification stage.
Autotalks used Keysight’s PathWave X-Series measurement application for 5G NR V2X on the MXA signal analyzer and the PathWave Signal Generation for 5G NR V2X on the EXG signal generator to test the TEKTON3 5G V2X transceiver.
The PathWave X-Series application is designed to provide testing for 5G NR V2X spectrum and power measurements, including channel power, spectral emission mask, adjacent channel power ratio, occupied bandwidth and complementary cumulative distribution function as defined in the transmitter conformance test specification.
Amos Freund, vice president of research and development at Autotalks, said, “To ensure the development of this technology, we strongly believe it must go through an advanced validation process. Working collaboratively with Keysight, we were able to validate our third-generation V2X chipset baseband and radio characteristics, paving the way for the most advanced safety use cases in the automotive industry.”
Thomas Goetzl, vice president and general manager of automotive and energy solutions at Keysight, added, “Sidelink is an essential enabling technology for 5G V2X Day 2 use cases that promise improved safety and a better overall driving experience.
“With our easy-to-use PathWave NR V2X signal analysis and generation software suite, Autotalks gained valuable access to 3GPP standard-compliant measurements and signals that saved R&D resources and time, as well as accelerated the verification of its TEKTON3 SoC.”
