FCC Adopts New Rules for Cellular Vehicle-to-Everything (C-V2X) Technology

The Federal Communications Commission (FCC) has taken a significant step forward in transportation safety and efficiency by adopting new rules governing cellular-vehicle-to-everything (C-V2X) technology. These rules, established in November 2024, provide a clear regulatory framework in the U.S. for C-V2X technology, allowing the use of three 10-MHz channels within the 5.9 GHz spectrum.

Improved Safety on the Roads

The new rules pave the way for enhanced collision avoidance, improved situational awareness, and support for vulnerable road users. C-V2X technology enables direct communication between vehicles and their surroundings, sending critical safety messages instantly and reliably. This instant communication can potentially save thousands of lives annually.

C-V2X also enhances driver awareness of blind spots and obstacles, particularly in complex environments, by sharing rich sensor data such as video feeds, radar, and LiDAR. The deployment timeline includes applications covering alerts for road works, emergency vehicles, and cyclists, further protecting pedestrians and non-motorized road users.

Efficiency and Smart City Integration

C-V2X technology leverages existing cellular networks (LTE and 5G) for broad and reliable coverage, reducing the need for costly roadside equipment and enabling continuous communication in both rural and urban areas. The combination of FCC-allocated spectrum and 5G network capabilities also enables higher throughput and lower latency, facilitating real-time sensor sharing and contributing to smoother traffic flows and reduced congestion.

C-V2X supports real-time vehicle-to-infrastructure (V2I) communications, enabling smart traffic signaling and coordinated traffic management, which increases overall transportation system efficiency. This integration with smart city technologies underpins the next generation of connected transportation technologies.

A Victory for Innovation and Public Safety

FCC Chairwoman Jessica Rosenworcel has stated that the decision is a victory for innovation and public safety. The new rules ensure efficient spectrum usage in the 5.9 GHz band dedicated to Intelligent Transportation Systems (ITS), and provide vital regulatory clarity and spectrum access that accelerate deployment and innovation in C-V2X.

The public is expected to benefit substantially from the safety benefits of the accelerated deployment of C-V2X systems. Devices previously approved under C-V2X waivers will remain operational under the new rules, and a timeline has been established for phasing out older DSRC-based technology. The auto industry and government agencies can now implement updated in-vehicle and roadside units operating on C-V2X technology.

The Commission's decision sets the stage for a smoother transition from older Dedicated Short-Range Communications (DSRC) systems to the more advanced C-V2X framework, supporting the development of automated driving technologies. Concerns about interference and out-of-band emissions remain under discussion, but efforts are ongoing to mitigate these risks.
