Facing a possible expansion of unlicensed Wi-Fi frequencies,a coalition comprised of the Intelligent Transportation Society of America, severalmajor auto makers, safety advocacy organizations, and transportation officialsare fighting to protect the 5.9 GHz band of spectrum previously set aside foradvanced vehicle communication systems. Proposed by the FCC, the expansioncould allow for a much greater use of unlicensed devices across the same bandused in newly developed vehicle to vehicle and vehicle to infrastructurecommunication systems, creating interference and destroying much of the new technologysaccident prevention potential.According to estimates from the US Department ofTransportation, these vehicle communication systems have the potential toprevent as much as 80% of all non-impaired vehicle accidents, giving drivers awealth of information about the road around them and warning them of impendingdangers. Data on a vehicles speed, location, and direction can be sharedacross a network of other vehicles, helping to paint a clear picture ofotherwise complicated intersections and dangerous blind turns. By sharing their5.9 GHz frequency with other unlicensed devices however, much of this lifesaving information could be interrupted.A study performed by the National Telecommunications &Information Administration determined that this communication technology couldhelp prevent the majority of types of crashes that typically occur in the realworld, such as crashes at intersections or while changing lanes. The studyconcluded that further analysis is required to determine whether and how theidentified risk factors can be mitigated..., and that While thestate-of-the-art of existing and proposed spectrum sharing technologies isadvancing at a rapid pace, NTIA recognizes the importance of these bands to thefederal agencies and the transportation industry and the potential risks ofintroducing a substantial number of new, unlicensed devices into them withoutproper safeguards.In a letter delivered to FCC Chairman Julius Genachowski,the coalition declared that, We support efforts to identify spectrum that maybe utilized to expand Wi-Fi applications. But with over 30,000 deaths on ournations roads every year, we also believe it is critical that efforts to openup additional spectrum do not come at the expense of revolutionary life-savingtechnologies. Scott Belcher, President and CEO of ITS America added that, TheU.S. Department of Transportation, automakers and high-tech leaders haveinvested hundreds of millions of dollars to develop connected vehicletechnology based on the availability of spectrum in the 5.9 GHz band. We are atthe cusp of it becoming reality, and we owe it to the American taxpayers toprotect their investment and see this life-saving innovation through toimplementation.The letter urges the FCC to do their due diligence inevaluating the potential effects of expanding available unlicensed Wi-Fi bands,considering the possibly disastrous ramifications before imposing the expansionplan. We stand ready to work with the NTIA, the wireless industry, and otherfederal and non-federal stakeholders to evaluate the feasibility of existing,modified, proposed and new spectrum-sharing technologies and approaches. However,this process should be allowed to proceed without a predetermination by the FCCthat spectrum sharing in the 5.9 GHz should be the ultimate outcome.The FCCs proposition, announced at the 2013 ConsumerElectronics Show in Las Vegas, is set to be formally discussed in a Commission meetinglater this month. If implemented, the expansion could be a significant setbackto next generation safety technology, though the outpouring of dissent seems toindicate that the proposed plan will likely be altered to protect the 5.9 GHzband. Accident avoidance technologies have become a major focus for auto makersin recent years, and as their capabilities have increased, incorporating theminto the real world has become much more complicated. Only though broadercoordination with the federal government, the high tech industry, and safety organizationscan a compromise be reached.
