| Abstract | Currently, the total energy consumption of the information and communication technology (ICT) sector is continuously increasing due to the fast penetration of ICT into many areas of business and society. Particularly high growth rates have been observed in the area of technologies and applications for communication networks. Over the last decade, there has been an exponential increase of both data traffic and number of devices connected to the Internet, which has led to a fast increase of network capacity. In this context, the role of the network infrastructure is becoming increasingly important because satisfying the need for high capacity generally means higher energy consumption of the network equipment. Especially mobile networks have experienced constant evolutions that have led to new technology generations and advanced radio interfaces capable of providing data rates in the order of hundreds of Mbps or even Gbps. Additionally, the number of active mobile subscribers has grown continually and rapidly. Even through the use phase is very important because of the high energy consumption and related greenhouse emissions of telecom infrastructures, it is just a part of the story. The whole life cycle, i.e., also the production and disposal phases should be considered when determining sustainability of communication networks, especially because of the relatively short life-cycle of ICT devices. In this paper, we report results of a study that apply widely used thermodynamic tools in combination with network modeling to assess sustainability of radio access networks. In particular, we utilize the concept of available energy or exergy to determine the environmental impact of the whole life cycle of radio access network infrastructure and present results of a case study of radio access network for the city of Vienna. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
