Each participant will have a "Whitebox" device, similar to a modem, installed in their household. The Whitebox will perform automated tests on the internet connection during different times of the day.

Participants can see the results of the testing on their broadband connections and no personal information or browsing histories are recorded. The testing is also designed not to interfere with volunteers' internet activities, the Commission promised.
