Energy efficient RRM strategies for current and upcoming TeTRA cellular systems

Abstract

Abstract-This paper aims at providing a thorough analysis of the energy efficiency of the TeTRA (TErrestrial Trunked RAdio) private cellular system. In particular some effective dynamic radio resource management solutions are presented, highlighting the impact on daily energy consumption. Moreover, the potential benefits of the transition which can be envisaged to the recently proposed TeTRA over LTE system are evaluated in terms of capacity and energy saving.

Energy Efficiency Perspectives of PMR Networks

“…Then, an evaluation of the energy performance of an optimized TETRA/TEDS system has been done, also taking into account the potential energy efficiency gain, due to hardware improvements and radio resource management flexibility that will be allowed by the transition to an LTE infrastructure. Since the evaluation of power saving solutions should be based on actual network configuration and traffic load scenarios, this work extends the results presented in [13] by introducing a detailed energy consumption analysis focused on the traffic data of a deployed TETRA regional network. Finally, the performance of the considered systems is evaluated both from an economic and an environmental point of view, showing the positive impact of the energy management improvements in current TETRA/TEDS systems and the significant energy saving gain allowed by the LTE platform.…”
