Environmental Engineering (EE); Principles for Mobile Network level energy efficiency
|Publication Date:||1 November 2012|
The present document is about network level energy efficiency measurements, aiming to assess the complexity of these measurements in real networks and in laboratory environments for the radio access networks framework. The radio access is deemed to be the most relevant energy consumption source in mobile networks. In particular the focus of the present document is on the "partial" radio access networks, representing a part of the whole network where the tests are to be performed; possible extension to wider networks ("global" in the following) is taken into consideration as well. In the networks analysed in the present document the considered elements are the so called "radio base stations", including any possible representation of them, but excluding radio network controllers, backhauling or any equipment connecting nodes to the core network. Energy efficiency of the User Equipment is not considered as well. Availability of data useful to estimate energy efficiency in the network is dealt with as well in the present document. The content of the present document is not intended to specify models, metrics or measurements procedures, rather to report them from an analytical point of view, aiming to highlight the feasibility and effectiveness of the various options.
The radio access technologies considered in the report under study are mobile networks such as GSM, WCDMA and LTE.
The present document also includes recommendations on possible future standardization work in the domain of wireless network energy efficiency assessment.
