Towards a low energy LTE cellular network: Architectures

One of the emerging challenges faced by industrialists and academics is reducing the energy consumption of cellular networks. The impact of the growing energy consumption, both to the environment and to the operational expenditure of operators can no longer be neglected. This paper introduces the Mobile VCE (MVCE) Green Radio project, and some of its investigation results regarding network architecture. The project has set itself a goal to reduce total energy consumption by 100-fold. This paper focuses on the optimization of architectures, with the aim of significantly reducing energy consumption, whilst maintaining or improving the quality of service (QoS).
