Base Station is the main contributor of energy consumption in cellular mobile communication. The traffic of base station varies over time and space. Therefore, it is important to quantify the influence of traffic generated on the power consumption. This paper investigates changes in the power consumption of base stations according to their respective traffic and develops a model for the power consumption as per traffic generated aiming to highlight the power consumption model development and address the power saving capabilities. The primary data in terms of power consumption and traffic load have been measured hourly on fully loaded 10 base stations for 10 days. The regression analysis shows the existence of a direct relationship between power consumption and traffic generated. A linear equation is developed is Y = 1.713×X + 1.274, where Y is power consumption and X is traffic generated, which shows that the power consumption of base stations linearly depends on the traffic generated. One noticeable point is that when the traffic is high, the developed linear equation indicates that the data fits well in the model but on the other hand, when the traffic is low, the developed linear equation explains less variability of the response around its mean. This paper also gives an overview of energy efficiency improvement possibility in base station.
