“…In order to analyze the economic cost of the network, we consider the cost model in [3], where the total cost is dominated by the cost of the spectrum licenses, energy and infrastructure. Thus, the total cost of the network can be written as…”

“…This tendency can be justified by the increasing energy costs combined to the growing energy consumption of the information and technology sector (that represents at least 10% of the global energy consumption [1], [2]). Moreover, the demand for data traffic in cellular networks has grown significantly, with forecasts ranging from a hundredfold to a thousandfold increase before 2020 [3]. Thus, the mobile network operators are challenged to meet the growing demands of the users while minimizing costs and consumption.…”

“…An example is given in [3], including infrastructure, energy and spectrum license costs. It is shown that for a given coverage area, it is more economically interesting to design a dense network with a larger number of base stations, than having a smaller number of base stations where each station covers larger areas.…”

“…It is shown that for a given coverage area, it is more economically interesting to design a dense network with a larger number of base stations, than having a smaller number of base stations where each station covers larger areas. However, factors as the cochannel interference and frequency reuse are not included in the analysis of [3], which can modify the conclusions.…”

Abstract-In this paper we carry out an energy efficiency and economic cost analysis of different cellular network designs. Our system model considers the co-channel interference, different amounts of available bandwidths and also the reuse of frequencies. The energy efficiency analysis employs a realistic power consumption model, while the economic analysis focus on infrastructure, spectrum licenses, and energy costs. Our results show that from an economic point of view the bandwidth cost and the number of employed base stations can be the most relevant factors to be balanced, while from an energy efficiency analysis it is more interesting to employ larger bandwidths and to balance the reuse of frequencies and the number of base stations. Moreover, although the system design under these two different points of view can be rather different, we also look into scenarios when the most energy efficient system design may also lead to the best economic option.
