Transportation community voices concern over potential risk to next generation vehicle safety techno
The Intelligent Transportation Society of America (ITS America), along with major automakers, safety advocates and transportation officials from across the country, are joining together to urge the Federal Communications Commission (FCC) to protect the 5.9 GHz band of spectrum set aside for connected vehicle technology—which is expected to save thousands of lives each year—from potentially harmful interference that could result from allowing unlicensed Wi-Fi-based devices to operate in the band.
The Wi-Fi expansion plan, announced by FCC Chairman Julius Genachowski at the Consumer Electronics Show last month, will be the topic of a February 20 Commission meeting in which the FCC plans to consider a Notice of Proposed Rulemaking to substantially increase the amount of unlicensed spectrum available for unlicensed devices in the 5 GHz band.
The 5.9 GHz band—one of two bands under consideration—was allocated by the FCC for development of vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications technology which the U.S. Department of Transportation (DOT) estimates could potentially address 80 percent of all unimpaired crash scenarios, saving thousands of lives each year.
According to the ITS America-led coalition, ‘We support efforts to identify spectrum that may be utilized to expand Wi-Fi applications. But with over 30,000 deaths on our nation’s roads every year, we also believe it is critical that efforts to open up additional spectrum do not come at the expense of revolutionary life-saving technologies.’
‘The U.S. DOT, automakers and high-tech leaders have invested hundreds of millions of dollars to develop connected vehicle technology based on the availability of spectrum in the 5.9 GHz band,’ said ITS America President and CEO Scott Belcher. ‘We are at the cusp of it becoming reality, and we owe it to the American taxpayers to protect their investment and see this life-saving innovation through to implementation.’
A study by the National Telecommunications & Information Administration (NTIA) recognized that connected vehicle technology ‘could help prevent the majority of types of crashes that typically occur in the real world, such as crashes at intersections or while changing lanes.’ It concluded that ‘further analysis is required to determine whether and how the identified risk factors can be mitigated…,’ and that ‘While the state-of-the-art of existing and proposed spectrum sharing technologies is advancing at a rapid pace, NTIA recognizes the importance of these bands to the federal agencies’and the transportation industry and the potential risks of introducing a substantial number of new, unlicensed devices into them without proper safeguards.’
In the letter to FCC Chairman Genachowski, the transportation leaders ask the Commission to allow for due diligence by ensuring that any timelines contained in a proposed rulemaking relating to the 5.9 GHz band are consistent with the NTIA schedule for completing its quantitative evaluation and issuing final recommendations, and do not precede a decision by the U.S. DOT regarding implementation of a connected vehicle network which has the potential to greatly reduce the 6 million crashes and more than 30,000 deaths which occur on U.S. roads annually.
‘We stand ready to work with NTIA, the wireless industry, and other federal and non-federal stakeholders to evaluate the feasibility of existing, modified, proposed and new spectrum-sharing technologies and approaches,’ according to the transportation leaders. ‘However, this process should be allowed to proceed without a predetermination by the FCC that spectrum sharing in the 5.9 GHz should be the ultimate outcome.’
