Following the Federal Communication Commission’s December decision to pursue reallocation of 75 megahertz in the 5.9 GHz band, public comments include support from Congress, criticism from amateur radio operators that use the frequencies in play, and pushback from transportation authorities.
FCC Chairman Aji Pai’s plan calls for dividing up the 75 megahertz as follows: the lower 45 megahertz would go for unlicensed uses like Wi-Fi, the upper 20 megahertz for C-V2X, and the remaining 10 megahertz would be the subject of public comment on whether it should remain for Dedicated Short-Range Communications or also go to C-V2X.
