There are also several open questions in the proposed rule-making. The DoT is using the comment period to solicit feedback, Freeman explained.
“They are asking for comments on whether the government should certify after-market V2V devices, for example. Another example: the document puts forward a preferred method for message authentication, but it also outlines a few alternatives and invites readers to provide comments on the merits of the alternative methods.”
Freeman isn’t taking anything for granted. Among comments submitted to the DoT over the next 90 days, he anticipates some to be focused on various technical aspects, “possibly suggesting alternatives to the methods proposed in the document.”
Expecting last-minute wrangling between the DSRC and anti-DSRC camps, he said, “I think it would be a mistake for the pro-DSRC camp to get complacent right now.”
Qualcomm versus NXP
Qualcomm, a long-time advocate of the cellular technology, has been at odds with NXP over development of DSRC-based V2V technology.
Now that Qualcomm is acquiring NXP, industry insiders are curious to know how the merger would affect policy — DSRC in particular.
Qualcomm once called DSRC a “dead-end” technology. Now it’s saying that it prefers a dual strategy supporting both DSRC and cellular for V2V communication.
