After reports surfaced that the FCC’s broadband speeds may skew low, the commission has switched speed test providers.

Now the FCC has announced that it is doing additional broadband speed testing research, and it will use a British company named SamKnows to conduct the tests.

SamKnows uses a different broadband speed testing methodology than comScore. While comScore’s testing uses software on a user’s computer, SamKnows uses a proprietary hardware device called a “White Box” that connects directly to a user’s broadband connection. The FCC is planning to divulge additional details about SamKnows’ methodology in a public filing.
