Communication base stations increase power consumption in winter

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%) .

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.

As a part of energy management, reduction of energy consumption by the towers is achieved by Green Radio Technology. The FIG1 clearly demonstrates that, the base stations alone consume more power than other parameters in cellular networks. The FIG2 shows the CO2 emissions in atmosphere by subscribers from base stations.

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%) . New research aimed at reducing energy consumption in the cellular access networks can be viewed in terms of three levels: component, link and network.

Power consumption in communication towers is reduced by adapting the network capacity to the actual demand at a given time. The cellular tower working will be based on the peak and off peak hours. In current scenario, even at the time of less traffic(less number of users) condition in a particular region,all the towers were made to work.

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.
