FCC CBRS Citizens Broadband Radio Service
by Nick Clark | Published April 25, 2026
FCC CBRS framework establishes shared-spectrum framework in 3.55-3.70 GHz band with three-tier sharing structure. Governed-marketplace substrate provides architectural foundation.
CBRS Frame
FCC CBRS establishes Incumbent Access (Tier 1), Priority Access (Tier 2), and General Authorized Access (Tier 3) sharing structure with SAS-mediated coordination.
Architecture Implications
CBRS operations require structural support for cross-SAS coordination, cross-tier admissibility, and emerging incident response.
Architectural Mapping
Governed-marketplace substrate supports CBRS spectrum operations. Cross-mesh federation supports cross-SAS coordination. Composite admissibility supports multi-tier authorization.
CBRS Evolution
CBRS deployment maturation, emerging Higher Power Limits proposal, and emerging emerging-band CBRS-class extensions push toward structurally-supported architecture.
