The Federal Communications Commission (FCC) has finalized a rule changing the 5.9 GHz band to support cellular-vehicle-to-everything (C-V2X) technology, which is intended to improve transportation safety and efficiency. By 2027, existing systems using older technology known as Dedicated Short Range Communications (DSRC) must transition to C-V2X, as the DSRC licenses will no longer be issued. The rule outlines technical guidelines for both roadside and vehicle units, emphasizes message priority for safety communications, and does not require compensation for entities transitioning to the new technology. The FCC expects these changes to enhance traffic safety while supporting the development of new transportation technologies.
Simple Explanation
The FCC is changing how cars talk to each other and the road to make driving safer. By 2027, old systems that help cars communicate must switch to a new, better technology, but some people are worried about how long it takes to make these changes and how it might affect other people using similar signals, like Wi-Fi.
