CalSPEED project teams use smartphones and tablets to test at nearly 2,000 identified points around the state to measure mobile broadband service availability. The data are interpolated and subject to verification measures before depicting estimated availability throughout California as shown on the broadband availability maps. See Broadband Availability Maps. CalSPEED’s software code is open source, and available to others to use or modify.
Field Testing Reports
Field test locations and results may be viewed on the Interactive Broadband Map.
Field Test Data
For ease of use, summarized data is the average of the 160 individual tests for each metric measured at each point tested. Data sets without such summarization are available upon request, and are posted at https://github.com/. The data is for public use.
Mobile Broadband Drive-Test Blog
The CalSPEED project includes
both a smartphone app and desktop app to acquire crowdsourced results from
consumer tests. Crowdsourced data appears as a selectable data layer on the
Interactive Broadband Map and is used for estimating broadband availability
for a particular location.
