Characterizing Energy Efficiency and Deployment Efficiency Relations for Green Architecture Design

Global warming and climate changing is among the major challenges in the 21st century. In wireless communications, green architecture design is an urgent demand for operators, not only because of the social responsibilities but also their willingness to reduce the network construction and operating cost. Previous literatures tried to tackle deployment cost and energy efficiency in a separated manner. However, these two aspects are interacting with each other and the design of green architecture needs a holistic consideration of both. In this paper, we try to shed some light on the green architecture design by analytically characterizing the open relations between energy efficiency and deployment efficiency, which is found somehow different from our intuition and there might not be a simple tradeoff between the two. This study has positive impact on the future network planning and optimization.
