MADISON, Wis. – The United States has a chance to make history in traffic safety through a proposed rule to mandate vehicle-to-vehicle (V2V) communication on light vehicles, a regulation that would govern cars that can “talk” to each other to avoid crashes.
And yet, the promulgation of a clear V2V mandate has stagnated with the slow pace of nominations by the Trump administration. Many cabinet agencies – including the National Highway Traffic Safety Administration (NHTSA) – remain stuck in staffing limbo.
Meanwhile, throughout the Notice of Proposed Rulemaking’s comment period – which just ended last month — the V2V debate has featured a prolonged battle over access to the radio frequencies designated for V2V systems. Automakers are on one side, cable companies and telecommunication technology companies on the other.
A slice of the radio space in question is 75 MHz of spectrum in the 5.9 GHz band, which Federal Communications Commission (FCC) in 1999 set aside exclusively for safety-related connected car applications using Dedicated Short Range Communications (DSRC) wireless technology.
Combatants angling to share that spectrum with WiFi mobile devices have banded together to push cellular-based technology for connected cars. DSRC technology proponents want to make sure the NHTSA brings home a V2V mandate. Companies such as Qualcomm and Broadcom see the 5.9 GHz band as the FCC’s single best near-term opportunity to make additional unlicensed spectrum available for broadband services.
In short, the V2V traffic safety debate at NHTSA has morphed into a fight over spectrum.

Did Savari flip?
Against this backdrop, Savari, a V2X (vehicle to vehicle, vehicle to infrastructure) technology supplier, announced Monday that it has joined the 5G Automotive Association (5GAA).
Savari’s move is intriguing for two reasons.
