Abstract
Cellular infrastructure in urban areas is provisioned to easily cope with the usual daily demands. When facing shockingly high loads, e.g., due to large scale sport or music events, users complain about performance degradations of the mobile network. Analyzing the impact of large scale events on the mobile network infrastructure and how users perceive overload situations is essential to improve user experience. Therefore, a large data set is required to get a detailed understanding of the differences between providers, mobile devices, mobile network access technologies, and the mobility of people.
In this paper, we present experiences and results from a crowdsourcing measurement during a music festival in Germany with over 110,000 visitors per day. More than 1,000 visitors ran our crowdsourcing app to collect active and passive measurements of the mobile network and the user mobility. We show that there is significant performance degradation during the festival regarding DNS and HTTP failures as well as increased load times. Furthermore, we evaluate the impact of the carrier, the access technology, and the user mobility on the perceived performance.
