Cellular Energy Efficiency Evaluation Framework

In order to quantify the energy savings in wireless networks, the power consumption of the entire system needs to be captured and an appropriate energy efficiency evaluation framework must be defined. In this paper, 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. The most important addendums over existing frameworks include a sophisticated power model for various base station (BS) types, which maps the RF output power radiated at the antenna elements to the total supply power of a BS site. We also consider an approach to quantify the energy efficiency of large geographical areas by using the existing small scale deployment models along with long term traffic models. Finally, the proposed evaluation framework is applied to quantify the energy efficiency of the downlink of a 3GPP LTE radio access network

In order to quantify the energy savings in wireless networks, a holistic view of the power consumption of the entire system needs to be captured. This requires an appropriate energy efficiency evaluation framework. In this deliverable, we present the necessary enhancements over existing performance evaluation frameworks for the wireless networks. The main objective is to capture the factors affecting the energy efficiency at component, node and network level. The most important additions to the existing frameworks include: (1) a sophisticated power model for various BS types, that maps the RF output power radiated at the antenna elements to the total supply power necessary to operate the network; (2) an approach to quantify the energy efficiency of large geographical areas by using the existing small scale deployment models along with long term traffic models; (3) a suitable set of metrics that allows quantifying the amount of energy savings capturing the most important trade-offs between energy savings and maintaining the system capacity, network coverage and quality of service parameters. After presenting the framework and necessary components of the framework, the proposed evaluation framework is applied to quantify the base station energy efficiency of 3GPP LTE. The overall promise of energy efficiency improvement is further investigated qualitatively for different possible areas of improvement in the system and some fundamental technology potential limits are also identified

How much energy is needed to run a wireless network?

In order to quantify the energy efficiency of a wireless network, the power consumption of the entire system needs to be captured. In this article, the necessary extensions with respect to existing performance evaluation frameworks are discussed. The most important addenda of the proposed energy efficiency evaluation framework (E3F) are a sophisticated power model for various base station types, as well as large-scale long-term traffic models. The BS power model maps the RF output power radiated at the antenna elements to the total supply power of a BS site. The proposed traffic model emulates the spatial distribution of the traffic demands over large geographical regions, including urban and rural areas, as well as temporal variations between peak and off-peak hours. Finally, the E3F is applied to quantify the energy efficiency of the downlink of a 3GPP LTE radio access network

The objective of this deliverable is to perform a first assessment of wireless access/multiple access technologies for the WINNER system concept. The study of multiple access schemes is the responsibility of Task 4 within the WINNER workpackage 2. The work requires the collection and assessment of the numerous ideas and proposals available. The technologies and combinations of technologies are also assessed and compared, to identify the most promising strategies and combinations. The latter work is primarily performed by multi-link simulation and system-level simulatio
