Base stations represent the main contributor to the energy consumption of a mobile cellular network. Since traffic load in mobile networks significantly varies during a working or weekend day, it is important to quantify the influence of these variations on the base station power consumption.
The real data in terms of the power consumption and traffic load have been obtained from continuous measurements performed on a fully operated base station site. Measurements show the existence of a direct relationship between base station traffic load and power consumption.
Due to lightning strikes, blown transformers, auto accidents, human theft and even rodents, power outages of BSs are actually much more than expected. Near one third of the BSs ever experienced power outages lasting for over 10 hours .
The largest energy consumer in the BS is the power amplifier, which has a share of around 65% of the total energy consumption . Of the other base station elements, significant energy consumers are: air conditioning (17.5%), digital signal processing (10%) and AC/DC conversion elements (7.5%) .
In this work, we formulate a novel problem for an unplanned emergency power outage at telecommunications base stations and propose a BPC algorithm to solve it to optimality.
