USA advances V2V mandate
The U.S. Department of Transportation (DoT) issued Tuesday a proposed rule to advance deployment of vehicle-to-vehicle (V2V) technologies. The action put the United States on a path as the first in the world to mandate V2V communication on all new light-duty vehicles.

NXP’s Reger commented, “It’s not my place to speculate what other companies are thinking about this.” But he quickly added, from “a techie person’s point of view, I know that there is no way around [DSRC]. When ultra-fast communication is demanded for emergency for example, you need direction communication. Otherwise you run the risk of [network] delays.”

In Reger’s view, the merger with Qualcomm will bring “the best-in-class cellular communication technology and ultra-fast direct communication technologies.”

Over time, he sees 802.11p (DSRC) and cellular 4G/5G “blended in a single system.” He said, “Users won’t have to do anything…the system can automatically choose between WiFi (802.11p) and 4G/5G” for appropriate applications.

Meanwhile, NXP is moving forward with further integration of its DSRC chipset. By mid-2018, Reger anticipates NXP to offer a single-die solution featuring “send and receive functions on DSRC” integrated with a crypto chip. Today, NXP is offering the same functions in three dies.

For security and privacy purposes, DSRC-based V2V technology mandates messages sent out of vehicles to be encrypted and messages received to be deciphered and authenticated. “It’s similar to what we do using a Public Key Infrastructure,” said Reger. NXP is implementing DSRC’s security process by using its own crypto chip – tested, proven and widely used in passports and other ID cards.
