The new broadband map produced by the U.S. Department of Commerce’s National Telecommunications and Information Administration (NTIA) released a new publicly available digital map that is intended to show areas where the minimum 25 Mbps downstream service defined as “broadband” is not available.
The mashup uses five different data sources, including data from both public and private sources. It contains data aggregated at the county, census tract, and census block level from the U.S. Census Bureau, the Federal Communications Commission (FCC), M-Lab, Ookla and Microsoft.
As always, assumptions matter. Microsoft, for example, once claimed about half of U.S. residents--163 million people--cannot get 25 Mbps service. In 2020, says Microsoft, 120 million cannot use the internet at 25 Mbps, or about 37 percent of all U.S. internet users . That is hard to believe.
The Microsoft data contrasts radically with Openvault data suggesting that, in the first quarter of 2021, less than 10 percent of U.S. internet users were accessing the internet at speeds less than 25 Mbps.
Microsoft says its methodology uses “anonymized data that we collect as part of our ongoing work to improve the performance and security of our software and services,”
I do not know the details of Microsoft’s methodology, but a reasonable person could think of lots of reasons why a particular application does not appear to operate at access connection speeds. Use of Wi-Fi provides a good example. But there are contention issues within some homes; use of mobile connections; device issues and in-building interference issues that might explain the vast difference between Microsoft’s claims and Openvault’s data.
