The US Federal Communications Commission (FCC) shared the proposal to the Public,  to open the 5.9 GHz band for Wi-Fi and automotive communications technology, and the decision will be made by the regulator on 12 December.

FCC suggested the lower 45 MHz of the band be made available for unlicensed uses like Wi-Fi and the upper 20 MHz to be allocated for Cellular vehicle-to-everything (C-V2X).  The FCC also appealed for public input on whether to allocate the remaining 10 MHz of the spectrum for Dedicated Short-Range Communications (DSRC) or C-V2X.

The sources noted that the expansion of C-V2X should be encouraged, as the technology would provide direct communications between vehicles and everything, including other vehicles on the road, infrastructure, cyclists and pedestrians.

FCC expressed this move will unlock new vehicle safety services, using less spectrum and on a much faster timeline than what realistically could see with a DSRC-focused policy. 

As per the FCC sources, there is no philosophy that we have to choose betweeen automoitive safety and Wi-Fi.   The given proposl  claimed would do far more for both automotive safety and Wifi.
