Techno-economic analysis for the deployment of PPDR services over 4G/4G+ networks

This paper presents a techno-economic study and sensitivity analysis for the deployment of PPDR services over next-generation networks. More specifically, the deployment of a core LTE network is investigated for providing PPDR services over 700 MHz for an urban scenario with severe shadow fading conditions. The service limits for user and bandwidth congestion for this network are examined and a backhaul solution at the microwave band is proposed via small cells. Techno-economic parameters are taken into consideration and both basic sensitivity analysis and multivariate simulations are presented to establish the robustness of network performance for certain channel and user conditions.
