Abstract (eng): | Energy consumption of mobile access networks has recently received increased attention in research carried out in both industry and academia. The cellular networks do not have considerable share in the overall energy consumption of the ICT (Information and Communication Technology) sector. However, reduction in energy consumption of mobile networks is of great importance from economical (cost reduction) and environmental (decreased CO2 emissions) perspective. The Thesis work has investigated the different means to enhance the capacity of evolved mobile networks and discussed the related challenges from energy consumption perspective; this discussion is followed by a simple radio network power usage model. Based on the model examples are given where two different deployment scenarios have been compared. Further the work focused on the WCDMA energy saving through femtocell deployment. A simple model for the energy consumption per unit area has been derived based on WCDMA downlink load equations. Based on the model, two different deployment scenarios have been compared to make the conclusion from energy consumption perspective. In the end, the impact of femtocells to the energy efficiency of the WCDMA network has been studied under the consideration of a valuable power save feature of femtocell. |
