Puvvala acknowledged the void created by the Trump administration’s dilatory approach to filling key positions. Nobody at this point is willing to predict when — or if — NHTSA might define a V2V mandate.
GM leads in DSRC
However, the automotive industry in the United States isn’t slowing its plans for DSRC-equipped car development, Puvvala added.
For example, GM is leading the industry with the deployment of the DSRC-equipped 2017 Cadillac CTS. Other big car OEMs including Ford and Chrysler are following suit, he said, with many RFQs and RFPs for DSRC flying around.

ABI Research predicts that the cellular-V2X group will “challenge the IEEE 802.11p/DSRC standard.”
Dominique Bonte, managing director and vice president at ABI Research, wrote earlier this year, “The evolutionary path offered by cellular technologies and their large supporting mobile ecosystem is an attractive option for automotive suppliers and OEMs eager to execute early implementations of autonomous functionality.”
“Cellular antagonists claim DSRC is more mature, reliable, secure, and ready to deploy,” Bonte stressed, “It remains to be seen whether it will survive the onslaught of the cellular ecosystem or continue to coexist with future cellular alternatives.”
In reality, the V2X standard debate – which was initially all about traffic safety – has been hijacked by a telecommunication industry hungry for spectrum for broadband services.
“The main challenge for cellular V2X is to get hold of dedicated spectrum needed for the Device-to-Device, or D2D, V2V protocol,” concludes Bonte. “While the intelligent transportation systems spectrum in the 5.9 GHz band was made available in the U.S., Europe, and other regions more than a decade ago, it remains reserved for DSRC. But this could change if, or more likely when, cellular giants like Ericsson, Qualcomm, and Samsung, unite and fight for lobbying power.”
