TL;DR: The most important addenda of the proposed E3F are a sophisticated power model for various base station types, as well as large-scale long-term traffic models, which are applied to quantify the energy efficiency of the downlink of a 3GPP LTE radio access network.

TL;DR: It is shown that it is possible to achieve significant energy reductions in an LTE network by introducing discontinuous transmission (DTX) on the base station side and insights on the impact of cell DTX from a life cycle assessment perspective are provided.

TL;DR: This paper evaluates the base station power consumption for different types of cells supporting the 3GPP LTE standard, based on a combination of base station components and sub-components as well as power scaling rules as functions of the main system parameters.

TL;DR: The necessary enhancements over existing performance evaluation frameworks are discussed, such that the energy efficiency of the entire network comprising component, node and network level contributions can be quantified.

TL;DR: A universal structure of cities is revealed, with core financial centers all sharing similar activity patterns and commercial or residential areas with more city-specific patterns, while the impact of local conditions still remains recognizable on the level of routine people activity.
