# Court rules FCC is allowed to reassign 5.9 GHz bandwidth, killing V2X ## Notes A technology like V2X only works if a substantial percentage of the vehicles on the road make use of it. But the continuing failure of automakers to actually build DSRC into their cars means there is no installed user base to benefit from the technology, even after two decades. That ongoing failure [has been evident to the FCC for many years](https://arstechnica.com/tech-policy/2013/02/wi-fi-expansion-could-harm-smart-car-wireless-network-automakers-say/). [In 2020, the agency finally decided to reallocate 45 MHz](https://arstechnica.com/tech-policy/2020/11/fcc-adds-45mhz-to-wi-fi-promising-supersize-networks-on-5ghz-band/) from 5.850 to 5.9252 GHz. This bandwidth would be taken away from automakers and highway planners and given to Wi-Fi, which has actual users who need bandwidth. ## Comments [vegetaman](https://arstechnica.com/civis/members/vegetaman.434431/) ##### Ars Centurion 9y[248](https://arstechnica.com/civis/search/member?user_id=434431) Hmmm... Sure seems like if "self driving cars" is going to be a thing, smart infrastructure and V2V comm would be a useful thing... But I mean, it'd have to be more robust than my laptop having a BSOD, so... Still seems like a mega pipe dream right now. # References 1. https://arstechnica.com/cars/2022/08/v2x-is-finally-dead-as-court-refuses-to-stop-fccs-5-9-ghz-reallocation/ # Footnotes
