  Collecting and analyzing meaningful data in mobile networks is the key to
assessing network performance. Crowdsourced Network Measurements (CNMs) provide
insights beyond the network layer and offer performance and other measurements
at the application and user-level towards Quality of Experience (QoE). In this
paper, the mobile Internet experience for Germany is evaluated with the help of
crowdsourcing from the perspective of an end user. We statistically analyze a
dataset with throughput measurements on the end device from Tutela Ltd., which
covers more than 2.5 million throughput tests across Germany from January to
July 2019. We give insights into this emerging methodology and highlight the
benefits of this method. The paper contains statistics and conclusions for
several large cities as well as regions in Germany compared to general
statements for Germany, since individual measurements and averages often only
imprecisely reflect the situation. The goal is to give a holistic view of the
performance of the current mobile network in Germany. Reading this paper, it
becomes evident that reliable statements about the quality of the mobile
network for Germany depend on a large number of peculiarities in different
regions with their own performance characteristics due to different network
deployments and population numbers.
