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.

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.

COSMOTE Q2–Q3 Performance
Ookla compared user-initiated tests taken on the Speedtest iOS and Android mobile apps from all
the major mobile carriers in Greece over the award period to determine who was the fastest. Based
on our data from Q2–Q3 2017, COSMOTE achieved a Speed Score of 37.72 providing faster average
speeds to their users than the other major providers in Greece with average download speeds of
41.94 Mbps and average upload speeds of 13.36 Mbps on LTE-capable devices.
Our Q2–Q3 2017 results are in for Greece and we have called COSMOTE as the winner of the Speedtest Award for fastest mobile network speeds.
