On November 20, 2024, the Federal Communications Commission (FCC) unanimously approved a Second Report and Order to transition the Intelligent Transportation System (ITS) from Dedicated Short-Range Communications (DSRC) to Cellular Vehicle-to-Everything (C-V2X) technology. This decision will enhance vehicle communication capabilities, improving road safety and traffic management.
C-V2X technology enables direct communication between vehicles, infrastructure, and vulnerable road users, facilitating real-time information exchange about road conditions, traffic signals, and potential hazards. This advancement is anticipated to reduce accidents and optimize traffic flow.
FCC Chairwoman Jessica Rosenworcel highlighted the significance of this transition, stating, “By modernizing the 5.9 GHz band, we are fostering advances in both wireless and transportation technologies while making our roads safer for drivers, pedestrians, and cyclists alike.”
The Order allocates 30 megahertz of spectrum in the 5.9 GHz band for ITS operations and establishes technical parameters for C-V2X devices. It also provides a timeline for phasing out existing DSRC-based technologies, ensuring a smooth transition to more advanced C-V2X systems.
Industry stakeholders have expressed support for the FCC’s decision. The 5G Automotive Association (5GAA), which petitioned for this transition, stated, “Today’s FCC decision will enhance roadway, cyclist, and pedestrian safety by enabling highly reliable and low-latency C-V2X communications.”
his move places the United States on par with global leaders in transportation technology, as several countries, including China, Germany, and South Korea, have already embraced Cellular Vehicle-to-Everything (C-V2X) technology to enhance their transportation systems. These nations have demonstrated the transformative impact of C-V2X on road safety, traffic management, and the integration of autonomous vehicle systems. The U.S. ensures its competitiveness in the rapidly evolving connected vehicle ecosystem by aligning with these international advancements.
The FCC’s decision to transition from the legacy DSRC system to C-V2X is expected to catalyze the deployment of cutting-edge, connected vehicle technologies nationwide. This change will spur innovation by encouraging collaboration between the automotive and telecommunications industries. For example, automakers will integrate C-V2X capabilities into new vehicles, while telecom companies will enhance infrastructure to support low-latency, high-reliability communication required for this technology.
Furthermore, the decision could stimulate significant investment in research and development, enabling U.S.-based companies to develop next-generation applications for smart transportation. These applications include advanced collision-avoidance systems, real-time traffic management platforms, and seamless communication between vehicles and smart city infrastructure.
Additionally, C-V2X technology aligns with the goals of autonomous vehicle development. By enabling real-time communication between vehicles and infrastructure, this technology provides the foundational framework for autonomous systems to operate safely and efficiently, even in complex traffic scenarios.
The FCC’s move also highlights the importance of spectrum allocation as a strategic resource for national competitiveness. The decision to dedicate spectrum in the 5.9 GHz band to C-V2X reflects a broader recognition of the role of advanced wireless communications in shaping the future of transportation.
Ultimately, this transition strengthens the United States’ position in the global race for connected and autonomous vehicle technology and lays the groundwork for safer, more efficient, and sustainable transportation systems. The FCC’s decision is poised to transform how Americans travel and interact with their transportation infrastructure by fostering innovation and collaboration across sectors.
