| Abstract | Traffic projections for the coming years indicate that the demand for wireless data is increasing exponentially, driven by new multimedia services and the wide availability of smartphones. A promising approach for providing additional required network capacity is the deployment of small cells in a heterogeneous network structure, which increases the spatial frequency re-use. However, the deployment of small cells into existing macrocellular networks can lead to interference and handover problems, particularly when re-using the frequency spectrum. In this paper, a novel configuration of the cellular network structure and frequency use for both macrocell and small cells is proposed to address these problems while maintaining high frequency re-use. Simulations for UMTS HSDPA show that the proposed multi-carrier heterogeneous network structure can increase the average user throughput of macrocells and small cells by 51% and 116% respectively, and the throughput of the worst 5th percentile by 213%, compared to a dedicated carrier reference deployment. The proposed solution also significantly outperforms partial frequency re-use deployments. |

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.
