Green Telecom Metrics in Perspective

Abstract: A fast and parallel evolution of ways to measure and assess energy efficiency in telecom has resulted in an entangled web of drafts and recommendations originating from government, research, and standards organizations. This paper focuses primarily on so-called "large network equipment" metrics and intends to capture state-of-the-art in this area of green communications. Competing approaches towards efficiency assessment are studied for their applicability and completeness, with special emphasis on topics relevant to future subject studies
