FCC proposes splitting 5.9GHz spectrum for vehicle comms and WiFi

November 21, 2019 / Ryan Daws

FCC chairman Ajit Pai is backing a proposal that would see precious spectrum allocated for vehicle-to-vehicle (V2V) communications split and also used for WiFi.The 5.9GHz spectrum was allocated for Dedicated Short-Range Communications (DSRC) way back in 1999 but it's been mostly ignored by automakers."DSRC  was intended to enable ubiquitous transportation and vehicle-related communications, but results haven't matched that intent," Pai said during an event in Washington.
"Here we are, two decades later, and the situation can at best be described as 'promise unfulfilled.'" Splitting the spectrum means that more devices can start using 5.9GHz for WiFi just like how the 2.4GHz and 5GHz are used today, reducing congestion in those bands.
