SUMMARY: In this document, the Federal Communications Commission (Commission) adopts rules and takes other steps to further address the transition of 5.9 GHz Intelligent Transportation System (ITS) operations from Dedicated Short Range Communications (DSRC)-based technology to cellular-vehicle-to-everything (C-V2X)-based technology. Specifically, the Commission adopts technical and operational rules governing devices using C-V2X-based technology, eliminates the DSRC requirement for communications zone designations, finalizes the timeline for sunsetting the use of DSRC-based technology, addresses the issue of additional spectrum allocations for ITS use, addresses the issue of reimbursing the transition costs of DSRC incumbents, and encourages the development of industry standards. DATES: This final rule is effective February 11, 2025. Existing licenses for DSRC systems may be renewed as necessary following this effective date but only for a period not to exceed December 14, 2026.
