Modeling of Power Consumption for Macro-, Micro-, and RRH-Based Base Station Architectures

In order to reduce the power consumption of cellular base stations (BSs), the following BS architectures have been developed: micro cell BSs, and remote radio head (RRH)-based BSs. In this paper, we propose a novel BS power consumption model for comparing the power consumption and energy efficiency of above three different BS architectures. The RRH-based BS architecture outperforms the conventional macro BS architecture with approximately 30% reduction in power consumption and 7 times increase in energy efficiency.
