The auto industry said it will pose a risk to vehicle-to-vehicle technologies that need this wireless spectrum

Automakers aren't too happy about a recent U.S. Federal Communications Commission (FCC) proposal, which uses part of the wireless spectrum assigned to vehicle-to-vehicle technology for Wi-Fi instead.

The FCC announced that it plans to free up 195 MHz of spectrum in the 5 GHz band for unlicensed use in an effort to address the U.S.' spectrum crisis. This could potentially lead to Wi-Fi speeds faster than 1 gigabit per second.

The FCC voted unanimously on the topic Wednesday of this week.

However, the auto industry said this would take away previously reserved wireless spectrum for vehicle-to-vehicle technology -- which has the potential to save lives.

The Alliance of Automobile Manufacturers, which is a trade group consisting of Detroit's Big Three Automakers, Toyota, Volkswagen AG and some other auto companies, is among those who are upset by the FCC's latest proposal.

"[Automakers] already invested heavily in the research and development of these safety critical systems, and our successes have been based on working closely with our federal partners," said the Alliance of Automobile Manufacturers. "It is imperative that, as we move forward, we do adequate research and testing on potential interference issues that could arise from opening up this band to unlicensed users and that the commission not rush to judgment before this important analysis can be done."

The Intelligent Transportation Society of America added that "the desire of the commission to move forward expeditiously, while cautioning against putting near-term life-saving innovations like connected vehicle technology at risk in the pursuit of future Wi-Fi applications."

The auto industry isn't the only one concerned with the new proposal. Certain government agencies -- like the Department of Homeland Security (DHS) -- see commercial users jumping on bands used by these agencies and posing a potential risk in doing so.

This "stop and go" traffic causes accordian-like compression waves that move through traffic. All of this could be eliminated if cars communicated with each other.


The main reason a line of cars cannot all accelerate at once has little to do with reaction time and everything to do with safety. Cars cannot safely travel at high speeds without significant space between them, and no technology can change those physics. A line of cars takes time to move because it takes time to restore the gaps which were destroyed by the stopping process.

If we all agreed to leave 30 to 100 feet (depending on the desired speed) between us and the car in front of us, even when stopped, then yes, we could all accelerate together. But, at the end of the day, you haven't gained anything other than confusing or angering the people behind you.
