FCC may tap connected-vehicle spectrum for next-gen Wi-Fi

Spectrum set aside for connected-vehicle communications and now under the control of the Department of Transportation may be opened up to unlicensed use to help accelerate deployment of next-generation Wi-Fi, which could bolster emerging 5G wireless communications.
Federal Communications Commission Chairman Ajit Pai recently said the commission wants to open up 1,200 megahertz of spectrum between 5.925 GHz and 7.125 GHz. However, 75 MHz of band in 5.9 GHz has become a contentious interagency issue. The FCC had set the spectrum aside for Dedicated Short Range Communications years ago to help promote development of vehicle-to-vehicle safety capabilities, but the technology hasn't gained traction.
Pai said his agency planned to open a "fresh look" rulemaking process for the spectrum.
After the announcement, however, Transportation Secretary Elaine Chao asked for a 30-day extension on opening up the rulemaking.
"It's totally appropriate and reasonable not to strand our policy and take a fresh look at how to use those airwaves," FCC Commissioner Jessica Rosenworcel said at a June 3 New America Foundation event.
At the same event, Commissioner Michael O'Rielly said the decision to move ahead with the rulemaking is "decided by the chairman."
He added that many of DSRC vehicular safety capabilities for which the spectrum was originally reserved have been shouldedr by other technologies that leverage licensed commercial spectrum, such as lidar-based capabilities, that can detect other vehicles and road hazards.
