A collaboration between Israeli chipset maker Autotalks and Luxembourg-based Rolling Wireless hopes to accelerate the deployment of V2X technology for bikes and cars.

Rolling Wireless is a supplier of cellular connectivity products for the automotive industry.

To satisfy the growing demand for 5G-V2X from manufacturers of vehicles, e-bikes and road infrastructure equipment, Rolling Wireless selected Autotalks’ Secton3 and Tekton3 chipsets.

The Rolling Wireles’ RX135x is a V2X module based on Autotalks’ Secton3 chipset, and samples are available for user programmes with production set to start in 2026.

Rolling Wireless is also developing a V2X module based on Tekton3 chipsets, more suitable for e-bike market needs, in addition to the vehicle needs.

“We are thrilled to collaborate with Autotalks to bring the first complete 5G-V2X option to market,” said Andreas Kohn, COO at Rolling Wireless. “Our combined strengths position us as the ideal partners for automotive, e-bike and road infrastructure manufacturers seeking robust and future-proof V2X.”

Yuval Lachman, Autotalks vice president, added: “Our joint efforts with Rolling Wireless help bring the next generation of V2X technology to the entire ecosystem. The RX135x module brilliantly demonstrates the capabilities of our Secton3 chipset, and its availability represents a significant milestone on the path to safer and more efficient road transportation for everyone.”

The chipsets support all four V2X sidelink communication standards: LTE-V2X, IEEE 802.11p (DSRC), 5G-V2X and 802.11bd. In addition to 5G-V2X operation, they enable the concurrent use of two radio technologies, such as DSRC plus 5G-V2X. This allows the integration of 5G-V2X while preserving compatibility with legacy technologies in existing installed bases.

The RX135x is a dual-mode V2X module supporting NR-V2X and DSRC 802.11bd as well as legacy LTE-V2X and DSRC 802.11p technologies. It allows single-channel as well as concurrent dual-channel operation. The module can be connected either to a Rolling Wireless 5G network access device (NAD), using the NAD’s application processor, or to any external host processor to run the V2X stack and applications.

Autotalks (www.auto-talks.com) helps reduce collisions on roadways and improve mobility with its automotive-qualified chipsets. It hopes its technology will be mass deployed in the coming years, complementing the information coming from other sensors, specifically in non-line-of-sight scenarios, rough weather or poor lighting conditions.

Rolling Wireless (www.rollingwireless.com) supplies NADs to the automotive industry, with more than 50 million automotive-grade cellular modules shipped to date. It was established as an independent company in 2020. Headquartered in Luxembourg, the company employs more than 250 people worldwide.
