Methodology To determine Speedtest Awards winners for mobile networks, we use results from “modern devices” to aid in the analysis of a mobile user’s average speeds. "Modern Devices" results include all mobile tests, regardless of connection technology used, as long as they were taken on devices that are identified as being capable of achieving the fastest speeds available in a country. Each top carrier accounts for at least 3% of the sample size in the geographic area.

The Speed Score uses a modified trimean to demonstrate the download and upload speeds that are available across a provider’s network. We take speeds from the 10th percentile, 50th percentile (also known as the median), and 90th percentile, and combine them in a weighted average using a 1:2:1 ratio, respectively. We place the most emphasis on the download speeds and median speeds as those represent what most network providers’ customers will experience on a day-to-day basis.
