Tutela collects data and runs network tests via software embedded in a diverse range of over 3,000 consumer applications, which enable the measurement of real-world quality of experience for mobile users, 24/7. For this report, we gathered 112,846,669.830 measurements, including over 16 million speed tests and 259 million latency measurements, from over a billion devices (iOS and Android smartphones) between March 1st and August 31st 2019.
Tutela measures network quality based on the real-world performance of actual network subscribers, inclusive of occasions when a network or tariff may be throttled or congested. Results in this report are based on a testing configuration designed to represent the typical (rather than maximum) performance that users experience. We use a 2 MB file to perform our download testing and a 1 MB file to perform our upload testing. Latency performance in this report reflects one-way UDP latency. Tests are conducted against the same content delivery networks that power many of the world’s most popular consumer applications, and as such reflect the end-to-end performance of the network.
