Rapporteur:  Mr. Hofmann, Juergen

Energy saving is important for operators' operational efficiency. Energy consumption is a significant operational cost factor, for example in developing markets, up to 30% of OPEX is spent on energy. For one operator group, almost 80% of base stations in Africa and India use diesel as the primary or as a backup power source. Furthermore, base stations account up to 80% of the total CO2 emissions in a mobile operator network. Many operators have a target to cut CO2 emissions as part of their environmental objectives. With increasing voice usage, data usage (e.g. introduction of smart phones, MTC devices, etc.) and more dense networks, the thirst for energy consumption is expected to increase further, hence, motivating the need for low energy base station technology. Increasing the energy efficiency of base stations or reducing the energy consumption of base stations will also facilitate the possibility for operators to power all types of base stations with alternative fuels and rely less on fossil fuels either from diesel generators or from the electricity grid.
The present document provides a study into BTS energy saving solutions. The present document analyses and evaluates different solutions to determine the benefits provided compared to the legacy BTS energy consumption.
