Ookla Speed Test

Mobitel Q3–Q4 Performance

Ookla compared user-initiated tests taken on the Speedtest iOS and Android mobile apps from all the major mobile carriers in Sri Lanka over the award period to determine who was the fastest. Based on our data from Q3–Q4 2017, Mobitel achieved a Speed Score of 13.01 providing faster average speeds to their users than the other major providers in Sri Lanka with average download speeds of 14.15 Mbps and average upload speeds of 7.59 Mbps on LTE-capable devices.

Speed Score

How Speed Score Works

The Speedtest Awards for top providers in speed are determined using a Speed Score that incorporates a measure of each provider’s download and upload speed to rank network speed performance (90% of the final Speed Score is attributed to download speed and the remaining 10% to upload speed). 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.

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.
