US industry body agrees on frequency spectrum for V2X

US industry body agrees on frequency spectrum for V2X

The Alliance for Automotive Innovation, which includes all major manufacturers and suppliers in the US, responsible for 99% of the light vehicles sold in America, has also committed to deploy at least 5 million V2X radios on vehicles and roadway infrastructure within the next five years. In the first five years of the plan, industry players will be able to choose either DSRC or C-V2X technology. After five years, a single technology will be selected and permitted to use the 5.9 GHz band going forward. This will also initiate a ten-year phase-out period, during which the technology that does not prevail will be phased out of the market.

V2X technology provider Autotalks is using the opportunity to express its belief that dual mode V2X chipsets can enable the US automotive industry to immediately start large-scale V2X deployment. With Autotalks’ chipset that supports both Dedicated Short-Range Communication (DSRC) and Cellular V2X (C-V2X), OEMs do not need to bet on which technology will prevail. According to Autotalks, this will allow carmakers to focus on bringing enhanced safety to the roads with V2X. While the company however regards the consensus as a step in the right direction, a lack of a uniform industry standard is likely to slow down deployment as auto companies will be concerned with making massive investments in a technology that might not be selected.

To tackle the problem, Autotalks has developed a dual mode V2X chipset (the world’s first, as the company claims). The chipset is designed to toggle between DSRC and C-V2X easily and quickly. The same hardware is used for both technologies, and through a simple configuration update, at a dealership or over-the-air, can switch the V2X technology. After configuration, all vehicles, regardless of the initially deployed technology, will be able to become part of a single large communication network.

“It’s great that the auto industry is committed to deploying the V2X technologies in the US. However, there is still uncertainty over which technology will prevail,” said Autotalks CTO and founder Onn Haran. “The adoption of our dual mode chipset ends the standards war. It eliminates any cost associated with betting on the losing technology. Once a V2X technology is selected, and devices are configured to the selected technology, no vehicle will be left out of the V2X network.”
