Rohde & Schwarz and Quectel cooperate on cellular-V2X for automotive 3GPP
Selected 3GPP test cases based on Rohde & Schwarz’s R&S CMW500 wideband radio communication tester for a Quectel AG15 C-V2X module have been verified by the two companies.
Cellular vehicle to everything (C-V2X) connectivity technology is expected to improve road safety and accelerate autonomous driving. The C-V2X PC5 interface operates in the 5.9GHz frequency to enable direct, reliable, low latency communication between vehicles (V2V), vehicles and infrastructure (V2I) and vehicles and pedestrians (V2P). According to Rohde & Schwarz, in order for the automotive industry to deploy this technology in a timely manner will require cooperation between suppliers.
The test cases performed by Rohde & Schwarz and Quectel can be used by automotive companies looking to pre-validate 3GPP system performance before entering OMNIAIR or CATARC certification processes. The test system provides a high degree of automation and flexible instrument configuration, which meets the requirements of the automotive industry for C-V2X testing, say the companies. Importantly, this can be done leveraging existing investments in Rohde & Schwarz equipment.
The Quectel AG15 is an automotive grade C-V2X module which has been designed and manufactured according to IATF 16949:2016 standards. It is intended for use in harsh environments and provides superior ESD/EMI protection performance, claims the company.
Manfred Lindacher, vice president of global sales automotive international, Quectel Wireless Solutions, commented: “We’re delighted to have collaborated with Rohde & Schwarz to validate these test cases and are looking forward to helping our customers on the road to build a smarter world with our automotive grade C-V2X modules.”
