Executive Summary

Network service providers, and other parties, require an accurate understanding of the performance cellular networks deliver to users. In particular, they often seek a measure of the network performance users experience solely when they are interacting with their device - a measure the authors call representative. Acquiring such measures is challenging due to the many factors, including time and physical context that influence cellular network performance. This paper makes two contributions. They conduct a large scale measurement study, based on data collected from a large cellular provider and from hundreds of controlled experiments, to shed light on the issues underlying representative measurements.
