On September 6, 2024, the United States Federal Communications Commission (FCC) published a Proposed Rule Making Notice (NPRM) on the Federal Release website to facilitate investments in the 3550-3700 MHz band. The NPRM contains an overview of the federal protection regime implemented by the United States National Telecommunications and Information Administration (NTIA), the Department of Defense (DoD), and the FCC, and seeks comments on updates to technology and services rules. The NPRM updates the original definition of exclusion zone, giving the definition of dynamic protected areas (DPAs) and adjacent areas of dynamic protected areas, and clearly requiring that the spectrum management system (SAS) cannot authorize CBSDs to work in exclusion zones, dynamic protected areas and adjacent areas of dynamic protected areas.
