Infrastructure Sharing: An Overview

Mobile network operators provide connectivity and communications service over deployed network infrastructure (whether owned or leased). The definition of network infrastructure is not only limited to electronic components but also includes passive elements such as physical sites and towers that are required to operate the network.

While subscribers do not perceive directly the composition/configuration of the infrastructure, the performance (e.g., throughput and latency) of the whole mobile network infrastructure determines the user experience and therefore the network infrastructure has been one of the key assets for mobile operators.
