In the last few years, mobile broadband communications operators have been confronted to an exponential growth of the traffic over their networks. Recently, the use of a broadcast component as a solution to face this growth has received a particular attention. In [1], a model for a hybrid network is introduced. This network consists in the inter-operation of a LTE unicast component and a DVB-T2 broadcast component. The introduced model allows the evaluation of the potential energy gain brought by such a network. In this paper, using an enhanced version of the model previously defined, we propose a new operating mode for the hybrid network that can improve the energy efficiency of the system.
