Potential Traffic Jam on V2V Communication Band

Potential Traffic Jam on V2V Communication Band

We’ve all experienced “traffic jams” on the internet. The network is like a huge road system with each site having its own exit. Just like on the interstate, if there are a lot of people trying to access the same site, speed slows down. The technology that allows our automobiles to communicate with each other and transmit information on potential hazards on the road ahead has its own dedicated 5.9GHZ wireless spectrum band. This means that the only “traffic” allowed to use this road is restricted to vehicle-to-vehicle (V2V) communications.

Republican Senator for Florida Marco Rubio recently proposed allowing access to this “road” by businesses and consumers in addition to V2V connectivity. This would mean that more traffic would be present which could potentially interfere with cars talking to each other. The Federal Communications Commission has yet to test the feasibility of the proposal. A statement from Rubio’s office seeks to ensure all concerned that the needs of connected car development would be balanced with the needs of other users sharing the band.

Major car groups are weighing in. The Association of Global Automakers, which includes manufacturers such as Honda, Hyundai-Kia, and Nissan, issued a statement saying they are “concerned” and that such a move would put at risk “the opportunity to save thousands of lives through the development of vehicle-to-vehicle communication.” The CEO of the Association, John Bozella, calls the step a “gamble.”

The Alliance of Automobile Manufacturers, including makers like General Motors, Ford, Chrysler, and Toyota, says it does not object to the project so long as legislators can ensure there will be no interference.

At this point, no one is sure. Testing is being conducted, but the connected car advocacy group, the Intelligent Transportation Society of America, highlights the need to do this testing “without arbitrary deadlines, restrictive parameters, or political pressure that could influence the outcome.”

The Department of Transportation also expresses “serious concern” stating that “at this time, the Department is unaware of any existing or proposed technical solution which guarantees interference-free operation.”
