A test measuring the rate at which data can be uploaded and downloaded by a device. Most also measure latency, the time it takes for a device to communicate with the server it is sending data to or receiving data from. Speed tests are available from many organizations and use varying methodologies.
As outlined in the National Telecommunications and Information Administration model challenge process, broadband offices can accept speed tests as evidence to support or rebut a speed-based challenge. Speed tests must be conducted three times at the same location on different days; the median upload and download speeds will be used for challenge purposes. The tests can be conducted by individual consumers, but must be collected and submitted by a nonprofit, government agency, or service provider.
