Terminal equipment and base station communication energy

What is a base station?

This work in the present document is defined as delivered useful bits to UEs covered by this Base Station. A Base Station is more energy efficient when doing more work with same energy, doing same work with less energy or in the best case doing more work with less energy.

What is the impact of base stations?

The impact of the Base Stations comes from the combination of the power consumption of the equipment itself (up to 1500 Watts for a nowadays macro base station) multiplied by the number of deployed sites in a commercial network (e.g. more than 12000 in UK for a single operator).

How is the energy consumption of a base station calculated?

The energy consumption of the Base Station under test shall be calculated during the whole test period. The total daily energy consumption of the Base Station will be the sum of weighted energy consumption for each traffic level i.e. low, medium and busy-hour traffic.

Which part of a wireless telecom network is dominating energy consumption?

In mobile telecom industry the energy consumption of the access network is the dominating part of a wireless telecom network energy consumption. Therefore, the core network and the service network are not considered in the present document. In a radio access network, the energy consumption of the Base Station is dominating.
