Optimizing LTE RAN for High-Density Event Environments: A Case Study from Super Bowl Deployments

Abstract	The soaring sales of mobile data usage, especially during high-traffic events like the Super Bowl, have prompted a new paradigm in the design and optimization of the LTE RAN. Mass sports events concentrate more than 70,000 people in a limited geographical area and therefore have an abnormally high demand on mobile networks, which is very high but short-lived. In this article, we examine the deployment practices and performance optimization approaches employed by MNOs for Super Bowl events over the period, with a particular focus on LTE RAN enhancements. We first outline the problems with High-Density Environments (HDEs), which include substantial uplink interference, saturated downlink channels, poor link quality, and frequent handover failures. However, conventional macro-cell-only network structures fail to meet such a requirement, leading operators to deploy heterogeneous networks (Het-Nets), where macro cells, small cells, DAS, and RRHs are deployed. Based on case studies extracted from actual Super Bowl deployments, we consider and evaluate the combination of these architectures and intelligent functionalities, including SON, CoMP, and dynamic scheduling algorithms. These approaches were complemented by predictive analytics and crowd modeling to aid per-event radio planning and spectrum provisioning.
