Automotive connectivity vehicle to everything V2X

Vehicle-to-Everything (C-V2X, 802.11p)

Testing network-based (Uu interface) connectivity and direct communication (PC5 interface)

Enhanced comfort in vehicles with sophisticated entertainment and safety-related applications drive the evolution of the automotive technology. With the fast progression of Cellular-V2X communication from LTE to 5G NR, the automotive industry faces new opportunities for ultra-low latency and highly reliable vehicle connectivity, one of the key enablers for the fully autonomous vehicles.

Another technology to improve safety and to enabled traffic participants and roadside units to directly exchange important information with each other is the PC5 direct communication, not only cellular network-based connectivity (Uu interface). Other communication paths like the "sidelink" that have been introduced in 3GPP Release 14 specifications offer new connectivity Cellular-V2X scenarios to enhance road safety and traffic flow.

Cellular network and C-V2X testing is required throughout all research and development and production phases. Innovative solutions are required by the automotive industry, to ensure safer mobility of the future.

Rohde & Schwarz offers proven 5G network and Cellular-V2X test and measurement solutions, valuable tools for the these unique challenges.

Your challenges in V2X testing

5G offers new possibilities, with the support for ultra-low latency and highly reliable vehicle connectivity, it can speed up the implementation of fully autonomous vehicles.

Reliability and accuracy: OEMs, as well as their suppliers, must ensure a reliable V2X connectivity for both network-based (Uu interface) communication as well as peer-to-peer data transmissions between traffic participants through PC5 direct communication. High reliability is required around the clock, even under the worst conditions of low signal-to-noise ratio (SNR), poor error vector magnitude or heavy network fading, while obtaining the most accurate GNSS positioning.

Interoperability: In-vehicle technologies must seamlessly work together. This is key to enable innovative digital mobility and new road safety applications. Comprehensive testing and conformity assessment is of great importance, especially for research and development processes that need to be fast and efficient.

Global conformance and certification: The mobile communication solutions for the automotive connectivity have to meet various global standards from IEEE802.11p, GCF, ITS and 3GPP releases, in different regional and global ecosystems. Innovative test solutions offer support in meeting those standards.
