在现代无线通信系统中，能量效率正成为一个非常重要的问题。同时，在尝试降低功耗时，保持QoS也至关重要。本文描述了一种异构无线通信网络结构，并分析了其功耗和QoS支持水平。结果表明，结合蜂窝通信与毫微微蜂窝可以显着降低整体功耗，这取决于毫微微蜂窝的使用。此外，当功耗下降时，QoS保持高。仿真结果还表明，考虑到功率效率，毫微微小区的实现率应该被限制在一定程度下，大约60%。最后，通过功耗和QoS的无差异曲线，给出了不同需求下的最优Femtocell采用方案。
Energy efficiency is becoming a very important issue in modern wireless communication systems. At the same time, maintaining QoS is also critical when trying to reduce power consumption. This paper describes a heterogeneous wireless communication network architecture, and analyses its power consumption and QoS support levels. The result shows that combining cellular communications with femtocells can significantly reduce overall power consumption, depending on the uptake of femtocell usage. Also, QoS remains high when the power consumption drops. The simulation results also suggest that the femtocell implementation rate should be limited under a certain degree, around 60%, in consideration of power efficiency. Finally, indifference curves of power consumption and QoS indicate the optimal femtocell adoption schemes under different requirements.
