Autotalks, a fabless semiconductor company dedicated to to vehicle-to-everything (V2X) communications, and Rolling Wireless, a provider of cellular connectivity solutions for the automotive industry, have announced a strategic partnership to accelerate the deployment of next-generation V2X solutions.
In response to the increasing demand for 5G-V2X solutions from manufacturers of vehicles, e-bikes, and road infrastructure equipment, Rolling Wireless has chosen Autotalks’ SECTON3 and TEKTON3 chipsets.
The SECTON3 chipset from Autotalks powers the Rolling Wireless RX135x V2X module. This module, designed to enable manufacturers to offer advanced (Day 2+) safety applications, is now available for sampling and targets customer programmes with production starting in 2026.
Rolling Wireless is also developing a V2X module based on Autotalks’ next-generation TEKTON3 chipsets, tailored to meet the needs of the e-bike market in addition to vehicles.
“We are thrilled to collaborate with Autotalks to bring the first complete 5G-V2X solution 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 solutions.”
“Our joint efforts with Rolling Wireless help bring the next generation of V2X technology to the entire ecosystem,” added Yuval Lachman, Autotalks’ VP Business Development Europe and US. “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.”
Autotalks’ SECTON3 and TEKTON3 chipsets are the first to support all four V2X sidelink communication standards: LTE-V2X, IEEE 802.11p (DSRC), 5G-V2X, and 802.11bd. Alongside 5G-V2X operation, they enable the concurrent use of two radio technologies (such as DSRC + 5G-V2X), facilitating the integration of 5G-V2X while maintaining compatibility with legacy technologies in existing installations.
The Rolling Wireless RX135x is a dual-mode V2X module that supports both legacy (LTE-V2X/DSRC 802.11p) and next-generation technologies (NR-V2X/DSRC 802.11bd). It allows for 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.
