One global V2X solution: DSRC and C-V2X

Why choose one when you can have both?

global v2x dsrc and c-v2x

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.

Autotalks can speak all languages: DSRC or C-V2X
At Autotalks, we decided to resolve the issue of the two competing V2X standards and design one global solution. By equipping our mass-market ready 2nd generation, automotive qualified chipsets with C-V2X, in addition to their native support of DSRC, 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 global V2X chipset: automotive qualified with production grade software
With its Global V2X solution, Autotalks delivers dual-mode (DSRC and C-V2X) functionality on its existing automotive qualified AEC-Q100 grade 2 chipsets while leveraging production grade software and maintaining the present API. This allows for the shortest time to market for a V2X solution that supports both DSRC and C-V2X.

The solution is not dependent on any cellular network
Autotalks global V2X solution does not need a cellular connect to work. There are many clear advantages to the separation from the cellular network both to the OEM and the consumer.

Benefits to OEMs:

  • Lowest development cost: Cost can be lower with only one global V2X platform and architecture
  • Certification feasibility: Clear isolation of V2X security assets
  • One Global certification: Every different NAD, per geography and Telematics class (low / mid / high), would require its own V2X certification
  • Cost-efficient C-V2X: Wide selection of NAD modems. Decoupling NAD selection from C-V2X support for cost optimization
  • Short boot time: Should be lower than 2 seconds, cellular modem is likely to exceed this target
  • Complex RF chains: Separation reduces the risk of interferences
  • Forced alignment between cellular network and V2X: Countries are migrating to 5G (and even to LTE) at a different pace

Benefits to the consumer:

  • Separation between Safety Messages and Infotainment: In order to ensure that all safety message will be delivered in real-time, V2X must be separated from the cellular network
  • Safe and Secure: Without separation from the cellular network, there is no assurance that cryptographic V2X assets are accessed only by allowed processes
  • Pay for what you use:V2X is optional. C-V2X isn’t used in all geographies. C-V2X cost shouldn’t be burdened when not used.
