[PDF] Reducing the power consumption in wireless access networks
A model for this power consumption of wireless access networks is presented and three base station types are investigated: macrocell, microcell, and femtocell base stations.
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.
However, the network energy consumptions of base stations have been growing quickly. How to save energy consumption in these dense layered network has become a problem we have to face. In this paper, we proposed a microcell BS (MicBS) switch algorithm to reduce the network energy consumption.
With the rapid development of wireless services and the improvement of coverage requirements, lots of micro base stations (MicBS) have been added to conventional Macro base station (MacBS) network. Heterogeneous deployment is one of the main features in future cellular network [ 1, 2 ].
In the simulations, we have tried several power levels, such as 20W, 40W. According to the rules of 3GPP organization, wireless base stations are divided into four categories, namely macro base station, micro base station, pico base station and femto base station.
