Their argument basically boiled down to this: we want to deploy V2V technology - the Alliance for Automotive Innovation promised 5 million pieces of V2V tech over the next five years - but we can’t until the FCC promises not to use some of the spectrum for Wi-Fi.įlash forward to 2022, and no vehicle on the road today is using V2V technology in any meaningful way. Calling V2X “a promise unfulfilled,” FCC chair Ajit Pai proposed to make the lower 45MHz of the band available for unlicensed uses such as Wi-Fi and allocate the upper 20MHz for C-V2X.Īutomakers lobbied against the decision, arguing that allowing Wi-Fi to use parts of the spectrum would interfere with connected car technology. And last year, tensions escalated when the FCC put out a new plan to use some of the spectrum set aside for V2X to expand Wi-Fi instead.
In 2017, the Trump administration announced that it was killing an Obama-era mandate that would have required new cars to be equipped with V2V technology. The auto industry was slow to develop V2X technology, and the rollout has been piecemeal Other automakers began looking closely at a newer technology called cellular V2X (C-V2X), using existing cell networks to send communications. General Motors also introduced V2V in the Cadillac CTS in 2017. Mercedes installed V2V equipment in both the 2017 E-Class and 2018 S-Class. Some experts say the wide deployment of the technology could help speed up the adoption of autonomous vehicles, which could use V2V communications to bolster their ability to “see” their environment and make better driving decisions.īut the auto industry was slow to develop V2X technology, and the rollout has been piecemeal.
It could also help prevent crashes by using that information to make decisions, like applying emergency braking. The problem, as hilariously put by Judge Justin Walker in his opinion, is that this technology has never really existedīut first, a little history lesson: in 1999, the FCC agreed to set aside 75 megahertz of spectrum in the 5.9 gigahertz band for something called dedicated short-range communications (DSRC) services, which would be used to improve road safety through V2X technologies.īroadly speaking, V2X allows vehicles to send and receive messages about road conditions, like speeding cars, weather, or traffic congestion.
