scope:

The present document defines a method to analyse the energy efficiency of wireless access network equipment.

The present document version covers the following radio access technologies:

• GSM.

• LTE.

• WCDMA.

• WiMAXT^M.

As the RBS power consumption is the dominant part of total power consumption of wireless access network, the present document covers methods which take into account only the RBS site power consumption when defining the total power consumption of wireless access networks. In the dynamic measurement, functionalities located in RNC or BSC node, which may have a significant impact on power consumption of base station nodes, are also considered.

The methodology described in the present document to measure energy efficiency consists of two parts. Within the present document they are referred to as static and dynamic measurements.

The results based on "static" measurements of the RBS power consumption provide a power consumption figure for RBS under static load and without radio network features activated. The results based on "dynamic" measurements of the RBS power consumption provide a power consumption figure for RBS with dynamic load and with radio network features activated, i.e. including the functionalities located in the radio network controller e.g. BSC/RNC.

Energy consumption of terminal (end-user) equipment is outside the scope of the present document.

The scope of the present document is not to define target values for the energy efficiency of equipment or networks.

The results should only be used to assess and compare the efficiency of mobile radio network equipment from different vendors featuring the same mobile radio standard and frequency band.

The present document does not cover multi RAT. Only Wide Area Base Stations are covered in this version. Other type of RBS will be considered in a future version of the present document.
