Green Cellular Wireless Networks: Where to Begin?

Conventional cellular wireless networks were designed with the purpose of providing high throughput for the user and high capacity for the service provider, without any provisions of energy efficiency. As a result, these networks have an enormous Carbon footprint. In this paper, the authors describe the sources of the inefficiencies in such networks. First they quantify how much Carbon footprint such networks generate. They also discuss how much more mobile traffic is expected to increase so that this Carbon footprint will even increase tremendously more. They then discuss specific sources of inefficiency and potential sources of improvement at the physical layer as well as higher layers of the communication protocol hierarchy.
