Broadband Mapping Program

The California Public Utilities Commission (CPUC) collects broadband availability data once a year and displays it on the California Interactive Broadband Map (User Guide) to provide Californians a means to look up broadband speeds and service providers in their area. The Map also provides information on funding eligibility by location for California Advanced Services Fund Infrastructure Account applicants. Equally important, the data inform public policies looking to bridge the digital divide in California.

The following links provide information on the CPUC's annual data collection process and other mapping resources and information.

• Broadband-Data-Submission-Guidelines-and-Templates: Instructions on the CPUC's annual data collection process. Includes data format descriptions, templates, and the link to the Broadband Data Upload Portal.
• CPUC Annual Collected Broadband Data: Provides most recent broadband availability data collected as part of the CPUC's annual data collection process, Pursuant to the Public Utilities Code Sections 281(b)(4), 281.6 and 5895.
• Broadband-Public-Feedback: A feedback tool on the California Interactive Broadband Map where the public can provide broadband feedback (e.g., service availability, speeds, etc.)
• Mobile Broadband Testing: The CPUC's CalSPEED program measures the reliability, quality, and availability of mobile wireless services. CalSPEED uses its own software in smartphones to take measurements at about 4,000 locations in urban, rural, and Tribal areas across California. You can find out how you can see these measurements and locations by using this CalSPEED how-to guide.
• Additional-Broadband-Mapping-Resources: Broadband mapping information from other sources like the Federal Communications Commission, the California Broadband Council, and the Broadband for All Portal.
