California Broadband GIS Data and Maps 


Wireline and Fixed Wireless data and maps show downstream speeds as submitted by broadband providers and validated by the CPUC.  Mobile maps and data represent downstream speeds resulting from CPUC mobile broadband fields tests for AT&T Mobility, Sprint, T-Mobile and Verizon Wireless, and for all other mobile providers, downstream speeds submitted by  the providers and validated by the CPUC.

SERVED STATUS Data and Maps:

Served Status data and maps show served, underserved, and unserved areas of the state.   A served area is defined per D.12-02-015 as an area with at least one broadband provider offering combined downstream speeds of at least 6 megabits per second AND upstream speeds of at least 1.5 megabits per second. Underserved is an area where broadband is available, but no wireline or wireless facilities-based provider offers service at advertised speeds of at least 6 mbps downstream and 1.5 mbps upstream. Unserved is an area with no service, or service slower than 768 kbps downstream and 200 kbps upstream.
