为了量化无线网络的能效，需要获取整个系统的功耗。在本文中，讨论了对现有性能评估框架的必要扩展。所提出的能效评估框架（(EF)-F - 3）最重要的补充是针对各种基站类型的精密功率模型以及大规模长期流量模型。基站功率模型将天线单元辐射的射频输出功率映射到基站站点的总供电功率。所提出的流量模型模拟了大地理区域（包括城市和农村地区）内流量需求的空间分布，以及高峰和非高峰时段之间的时间变化。最后，应用(EF)-F - 3来量化3GPP LTE无线接入网络下行链路的能效。
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 ((EF)-F-3) 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 (EF)-F-3 is applied to quantify the energy efficiency of the downlink of a 3GPP LTE radio access network.
