The Autotalks TEKTON3 and SECTON3 chipsets were verified using the R&S CMP180 radio communication tester to ensure the correct operation of the 5G-based vehicle to vehicle and vehicle to infrastructure V2X functions.

The TEKTON3 and SECTON3 chipsets are the first chipsets to support all four V2X sidelink communication standards; LTE-V2X, IEEE 802.11p (DSRC) and the new 5G-V2X and 802.11bd. These chipsets not only support 5G-V2X operation but can accomplish this while operating another radio technology concurrently. This allows incorporating 5G-V2X while maintaining the install base on the legacy technology. For example, in Europe, where 5G-V2X is expected to be launched first, DSRC can be supported in parallel.

The R&S CMP180 radio communication test platform is a non-signalling system for wireless devices supporting cellular and non-cellular technologies. 5G-V2X test capability has been recently added to the R&S CMP180 by Rohde & Schwarz, meaning the complete range of V2X technologies supported by Autotalks’ chipset was able to be tested using a single instrument.

The single box tester comes equipped with two analyzers, two generators and two times eight RF ports, plus the possibility to scale up by stacking several testers. This makes it an ideal solution for simultaneous measurements of different technologies and devices in R&D and mass production, which means customers can use the R&S CMP180 to test simultaneously all three V2X sidelink standards.

V2X is a key technology which increases traffic efficiency, improves road safety, and enhances autonomous driving. This enables direct, reliable, low latency communication between vehicles (V2V), vehicles and infrastructure (V2I) and vehicles and pedestrians (V2P). 5G-V2X with its higher order modulation and two-way group communication enables new use cases including cooperative manoeuvres such as lane merging and advanced sensor data sharing.

Qualcomm is currently in the process of acquiring Israel-based Autotalks but facing market investigations by the UK and EU authorities.

“The close collaboration with pioneering V2X chipset (https://www.eenewseurope.com/en/worlds-first-5g-v2x-chipset-verification/) vendor Autotalks helps to mutually validate our solutions, provide a trusted reference to our respective customers and accelerate the deployment of 5G-V2X by the entire ecosystem. We are proud to work with Autotalks and that the new 5G-V2X capability of our radiocommunication tester was instrumental in this important step for the industry,” said Christoph Pointner, Senior Vice President Mobile Radio Testers at Rohde & Schwarz.

Amos Freund, Vice President R&D at Autotalks, says: “Validation is a critical step in the product development cycle and a condition to an interoperable ecosystem. Our collaboration with Rohde & Schwarz not only helps us but the entire market by maturing the 5G-V2X technology.”

Rohde & Schwarz will show a 5G-V2X test setup with the R&S CMP180 and a third-generation chipset from Autotalks at Mobile World Congress 2024 in Barcelona later this month.
