| Abstract | The 38GHz band point-to-point fixed wireless access (FWA) system with a maximum throughput of 600Mbps has been developed. Generally, the TDD (Time Division Duplex) system is configured with one antenna by sharing the transmission and the reception in the same radio frequency channel. This configuration can reduce the antenna mounting space, but the residual interference from the transmitter in off-stage to the receiver in offstage should be sufficiently suppressed by using the transmission/receiving selector switch (TDD-switch) at the antenna port. The insertion loss of the TDD-switch with enough on/off ratio becomes large in the millimeter-wave band, and it becomes difficult to secure stable transmission power during the switching between the transmission and the reception. For these reasons, this FWA system has adopted the configuration where two separate antennas with the same polarization, are arranged in H-plane for the transmission and reception are installed individually as shown in Fig. 1. Spatial isolation between those two antennas dispenses with the TDD-switch. The introduction of a shielding metal wall between the two antennas is also investigated to enhance the spatial isolation to more than 65dB. |

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.
