Broadband Maps and GIS Data

Wireline and Fixed Wireless Broadband Availability Data as of Dec. 31, 2016

Partial Data

We are in the process of updating the mobile broadband availability layer. The Wireline and Fixed Wireless data sets are complete. We will be updating the mobile data and other links listed below as they become available.

Caveat

The data set is based on the information available at the time of publication. Broadband data is submitted by providers, and although we take steps to validate its correctness, the CPUC does not warrant its accuracy. We are only able to require data to be given to us by census block, so a provider that reports deployment of a particular technology and bandwidth in a census block may not necessarily offer that service everywhere in the block. Accordingly, a list of providers deployed in a census block does not necessarily reflect the number of choices available to any particular household or business location in that block, and the number of such providers in the census block does not purport to measure competition. For that reason, the information on our map layers represents a rebuttable presumption of coverage, which can be, and often is, rebutted in the process of reviewing CASF applications. Public feedback may be provided to correct the data.

Broadband Deployment Maps and GIS Data (as of December 31, 2016)

Wireline and Fixed Wireless maps and data 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.
