How much energy does the Vaduz base station use for communication

Do base stations dominate the energy consumption of the radio access network?

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.

What is the power consumption of baseband processing?

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.

What are the main components of a base station Power model?

The main components are the baseband processing unit, analog frontend, power amplifier, and power supply as well as active cooling. As the main components are common to most of the models, they can be easily combined to form a new model. Most of the base station power models are based on measurements of LTE (4G) hardware or theoretical assumptions.

How do Björnson/Hossain/Peesapati models calculate baseband processing 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.
