This map shows the Cellular Geographic Service Area (CGSA) boundaries overlaid on top of Cellular Market Areas (CMAs) for the B Block 800 MHz cellular licenses. The purpose of this map is to depict the licensed CGSAs in each CMA (as of January 11, 2012) as the FCC considers a rulemaking to revise the licensing model for cellular licensing from a site-based model to a geographic-based model. Gulf of Mexico Exclusive Zone (GMEZ) not shown. See CFR47 Section 22.950 (c).
