First dual-mode DSRC/C-V2X chipset makes the grade with Rohde & Schwarz

Test and measurement firm Rohde & Schwarz has validated a new dual-mode DSRC and C-V2X chipset from Autotalks, as the Israeli chip-maker also claims expansion into China.

The lack of regulation around safety-critical vehicle-to-everything connectivity in the automotive sector has seen both dedicated short-range communications (DSRC) and cellular V2X (C-V2X) standards emerge, each with different architectures.

Autotalks has claimed the world’s first dual-mode AEC-Q100 grade 2 chipset, after adding C-V2X to its native support of DSRC. The chipset supports DSRC based on 802.11p/ITS-G5 standards and C-V2X based on 3GPP Release 14 and Release 15 specifications.

Rohde & Schwarz and Autotalks have tested the solution with the test company’s CMW100 communication tester. During the test, multiple test scenarios were verified for transmission and reception of C-V2X direct communications (PC5) based on 3GPP Release 14 using GNSS based synchronisation.

Autotalks is putting increased focus to bring its V2X offering to China, having recruited a new business development chief in the region.

Amos Freund, vice president of R&D at Autotalks commented: “The radio performance and security merits of our global solution coupled with our recent expansion into China put us in a great position towards mass commercialisation of C-V2X technology in China and elsewhere in pursuit of saving lives on roads in the near future.”

Anton Messmer, vice president of mobile radio testers at Rohde & Schwarz, said: “We are happy that Autotalks chose Rohde & Schwarz to provide instruments needed to reach this milestone. Rohde & Schwarz enables the automotive industry in validating the functionality and performance of C-V2X devices with our comprehensive test suite.”

Car maker Hyundai bought a stake in Autotalks this summer. The pair will work together to accelerate deployment of “next generation chipsets” for connected cars, the South Korean firm said.
