Three key federal agencies confirmed they have begun testing technologies to allow unlicensed users to share the same spectrum allocated to automobile manufacturers for vehicle safety detection and avoidance technology, according to a letter to Senate Commerce, Science and Transportation Committee Chairman John Thune (R-S.D.), obtained by Bloomberg BNA.

The Federal Communications Commission will refresh the record on its pending rulemaking proceeding on spectrum sharing of the 5.9 gigahertz (GHz) band, the FCC, Department of Transportation, and Commerce Department’s National Telecommunications & Information Administration said in the letter.

Tests conducted to date by the DOT, “combined with the results of this FCC test plan will provide reliable, realworld data on the performance of unlicensed devices that are designed to avoid interfering with DSRC [dynamic short range communications] operation in the 5.9 GHz band,” they said in the letter, which is a response to Sept. 9 letters from Thune and the automotive and telecommunications industries urging the agencies to begin testing technologies in the band.
