Multicast and Unicast in Serving Public Safety Traffic On-Demand Session
Given a significant amount of group traffic in public safety incidents, multicast has the potential to outperform unicast in terms of precious spectrum savings and first responders' experience. In this study, and for both unicast and multicast, we explore components along the chain from initial first responders' deployment locations to the resulting network performance and user experience with considerations on Multiple-Inputs-Multiple-Outputs (MIMO) technologies and public safety incident coverage. We also identify, quantify, and visualize major factors that contribute to the resulting first responders' experience.
