With the steady increase in the use of mobile technologies, studying the energy consumption of mobile applications becomes more interesting. In this thesis, the energy consumption of such applications connected to Long Term Evolution (LTE) cellular networks is studied. Using physical measurements on a mobile device, this thesis aims at characterizing the energy consumption due to communication of a mobile device connected to an LTE network in order to extend EnergyBox. EnergyBox is a tool that estimates the communication energy of mobile devices using packet traces as input. We perform systematic experiments which exercise the LTE network interface of a mobile device while measuring the consumed power. Using the resulting data and a literature review of the operation of the LTE interface an energy model for LTE is developed. The model is then implemented in EnergyBox. The evaluation of the model is performed by comparing the accuracy of the energy model to physical measurements using five different packet traces from different mobile applications. The results show that the model integrated in EnergyBox provides an average accuracy of between 90% and 100%.
