The Wi-Fi community is encouraged by efforts at the FCC to free up more unlicensed spectrum by re-examining the 5.9 GHz band, but the auto industry remains divided over the use of Dedicated Short Range Communications (DSRC) and C-V2X.

FCC Commissioners Michael O’Rielly and Jessica Rosenworcel sent a letter to Toyota on Thursday noting Toyota’s announcement last month that it would be deploying DSRC in Toyota and Lexus vehicles sold in the U.S. starting with the 2021 product line. Toyota’s technology will use the 5.850-5.925 GHz band allocated for Intelligent Transportation Systems.

Asked about the 5.9 GHz band during a press conference after the commission’s open meeting on Thursday, Rosenworcel said they were supposed to receive testing results from the Department of Transportation, the Department of Commerce and the FCC regarding how the U.S. could simultaneously accommodate unlicensed and auto safety use in this spectrum. But those test results were never presented when they were due in January 2017.
