Power consumption of Bandar Seri Begawan communication base station

Of the other base station elements, significant energy consumers are: air conditioning (17.5%), digital si gnal processing (10%) and AC/DC conversion elements (7.5%) . terms of three levels: co mponent, link and network. efficiency of the power amplifier. Efficiency can be improved using a specially designed power

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.

Furthermore, the base stations dominate the energy consumption of the radio access network. Therefore, it is reasonable to focus on the power consumption of the base stations first, while other aspects such as virtualization of compute in the 5G core or the energy consumption of user equipment should be considered at a later stage.

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.

The Björnson/Hossain/Peesapati models calculate the baseband processing power consumption as the sum of the power required for channel estimation, coding and decoding and linear processing. It depends on the number of antennas at the base station, the number of users, the data rate per user, and the bandwidth.

The power consumption of the baseband processing is defined as a constant value in the Auer, Holtkamp, and Piovesan models. In the Holtkamp model, it is scaled linearly with the bandwidth and the number of employed antennas.
