Please note that the Consumer Broadband Test in its current software based form may not be an accurate representation of connection quality provided by your broadband provider. The results can be impacted by a range of factors -- for instance, the test can vary based on the geographical distance of the user from the testing server, end-user hardware, network congestion, and time of day.
The REAL reason for these tests - broadband mapping data:
FCC may use data collected from the Consumer Broadband Test (Beta), along with submitted street address, to analyze broadband quality and availability on a geographic basis across the United States.
Powerboost and other factors are inconsequential to the main purpose - mapping data.
