Cellular Geographic Service Areas

The Wireless Telecommunications Bureau’s map files for Cellular Geographic Service Areas (CGSAs) in GIS Shapefile and GeoJson formats are now available to the public. For further information, see the Public Notice.

The map files are updated to reflect 800 MHz Cellular Service applications filed, returned or granted, thus placing at the fingertips of interested parties -- in a centralized location -- the FCC information necessary to determine more quickly the area in every Cellular Market Area -- Blocks A and B -- that remains unserved and available for licensing.*
