TESTING METHODOLOGY<br />

For Fastest Mobile Networks <strong>2017</strong>, we used custom field-test software designed<br />

by Ookla, the creator of Speedtest.net. The software was loaded onto sets of four<br />

Samsung Galaxy S8 phones. We chose the S8 because it was, at the time we<br />

tested, the only device able to access new “gigabit LTE” networks at full speed.<br />

Three sets of phones were driven around the country in rental cars: one down<br />

the east coast, one down the center of the country, and one down the west coast.<br />

The software runs tests every 90 seconds. We measured uploads and downloads<br />

to a neutral, non-carrier server as well as pings to the nearest server in Ookla’s<br />

network. Over the course of driving, we tested downloads from 160 different<br />

servers and pings to 407 different servers.<br />

We stopped at between 12 and 15 locations, for at least 15 minutes each, in each<br />

of 30 cities. We averaged the data in each location, then averaged the locations<br />

together for an overall city result. The aggregated data from traveling between<br />

the test locations counted into the overall averages as two more locations. As we<br />

are testing LTE networks, we did not average in speeds on non-LTE networks.<br />

If a phone dropped off an LTE network, it was treated as though the test failed.
