Global V2X Solution Improves Safety For The Connected Car


Autotalks’ new Vehicle-to-Everything (V2X) chipset supports both dedicated short-range communications (DSRC) and cellular’s C-V2X based on 3GPP specifications.

With a race toward connected and autonomous vehicles, cars are beginning to communicate with other cars and objects in its surroundings in order to improve the overall efficiency and safety of the roadways. One of the most important choices that designers have to make during their implementation is to choose the right communication technology.

Divergence of V2X standards requires a global solution

Recently, leading car manufacturers announced their intentions to equip new lines of vehicles with V2X communications. Since there is no regulation specifying how the safety critical messages should be communicated, V2X diverged into two different standards, DSRC and C-V2X, with fundamentally different architectures. This makes it difficult for OEMs to decide which standard they should choose and even more difficult to harmonize a single global solution.


To solve this problem, Autotalks created the world’s first dual mode chipset. With Autotalks’ Global V2X solution, OEMs no longer need to choose one technology – they can now have both DSRC and C-V2X.

Autotalks’ chipset can speak all languages: DSRC or C-V2X

The new deployment-ready, 2nd generation V2X chipset is the only available solution capable of supporting both DSRC and C-V2X direct communications (PC5 protocol) at the highest security level.

By adding C-V2X to its existing 2nd generation automotive qualified chipset, Autotalks is paving the way to road safety everywhere, the announcement stated.

The chipset supports DSRC based on 802.11p/ITS-G5 standards and C-V2X based on 3GPP specifications.

While DSRC-based V2X is deployed in the US, Europe and Japan, C-V2X is gaining momentum in other regions.

Autotalks chipsets were designed from the ground up to meet V2X market requirements and standards, which gives its C-V2X offering a head start to meet security, environmental, quality, thermal and other requirements.

Delivering dual-mode (DSRC and C-V2X) functionality on existing automotive qualified AEC-Q100 grade 2 chipsets while leveraging production grade software and maintaining the present API, enables the shortest time to market for a global dual-mode V2X platform, the company noted.

Autotalks solution is expected to minimize development, testing and certification efforts for a V2X system to be deployed anywhere, via a software-defined toggle between V2X technologies.

Autotalks’ PC5 solution utilizes the globally defined 5.9 GHz ITS spectrum for V2X and is cellular network agnostic (no cellular SIM or coverage required, works without or with any 3G/4G/5G cellular modem).

Separating V2X from the cellular Network Access Device (NAD) improves the cost-effectiveness of Telematic Control Unit (TCU) deployments. The separation of V2X from in-vehicle infotainment ensures that the purpose of the V2X system, which is giving drivers alerts of on-road dangers, is not compromised.

“Autotalks is proud to announce that its existing 2nd generation chipset can now support PC5,” said Hagai Zyss, CEO of Autotalks. “It is a revolutionary stride proving Autotalks’ market leadership. This demonstrates that a truly secure global V2X solution could have only been developed by a company that has multidisciplinary experience in creating automotive safety communication solutions. We are committed to staying forward thinkers and bringing to mass-market a V2X solution that will save lives in all regions and protocols in the most cost-efficient manner.”
