Almost two decades ago the U.S. Federal Communications Commission set aside the 5.9 GHz band for dedicated short range communications with the goal of letting vehicles communicate with one another using unlicensed airwaves. Since that move in October 1999, DSRC is currently available in Cadillac CTSs but isn’t available in new U.S. models, according to several sources. Given this lack of adoption, a trade group representing the cable industry wants the FCC to open the valuable mid-band frequency up for alternative uses, particularly Wi-Fi.
