  • Compatibility and Sharing Analysis Between Dvb–T and Ob (Outside Broadcast) Audio Links in Bands Iv and V
    ERC REPORT 90 European Radiocommunications Committee (ERC) within the European Conference of Postal and Telecommunications Administrations (CEPT) COMPATIBILITY AND SHARING ANALYSIS BETWEEN DVB–T AND OB (OUTSIDE BROADCAST) AUDIO LINKS IN BANDS IV AND V Edinburgh, October 2000 ERC REPORT 90 Copyright 2000 the European Conference of Postal and Telecommunications Administrations (CEPT) ERC REPORT 90 Executive Summary This study assesses the compatibility between OB links and DVB–T in bands IV and V and determines the necessary separation distances between OB links and DVB–T as a function of frequency. The study takes account of three spectrum masks: the spectrum mask for sensitive cases according to the Chester Agreement, 19971 and the two spectrum masks recommended by SE PT 212. The results are only valid for the DVB–T and OB links system parameters given in this study. In order to establish if in a given set of circumstances: - the DVB-T service and - OB link usage at a given location are compatible, the relevant separation distances derived in Sections 2 and 3, must be examined. If both separation distances are respected, then usage is compatible. The main results of the study are as follows: • In most cases, Co-channel operation (frequency difference from 0 to 4 MHz between the centre frequencies) of DVB–T and OB links within a DVB–T coverage area will cause unacceptable interference to OB links and vice-versa. • For an operation of OB links in the 1st adjacent channel of DVB–T (frequency difference from 4 to 12 MHz between the centre frequencies), the necessary separation distances obtained in this study are quite large.

  • The Economics of Releasing the V-Band and E-Band Spectrum in India
    NIPFP Working Working paper paper seriesseries The Economics of Releasing the V-band and E-band Spectrum in India No. 226 02-Apr-2018 Suyash Rai, Dhiraj Muttreja, Sudipto Banerjee and Mayank Mishra National Institute of Public Finance and Policy New Delhi Working paper No. 226 The Economics of Releasing the V-band and E-band Spectrum in India Suyash Rai∗ Dhiraj Muttreja† Sudipto Banerjee Mayank Mishra April 2, 2018 ∗Suyash Rai is a Senior Consultant at the National Institute of Public Finance and Policy (NIPFP) †Dhiraj Muttreja, Sudipto Banerjee and Mayank Mishra are Consultants at the Na- tional Institute of Public Finance and Policy (NIPFP) 1 Accessed at http://www.nipfp.org.in/publications/working-papers/1819/ Page 2 Working paper No. 226 1 Introduction Broadband internet users in India have been on the rise over the last decade and currently stand at more than 290 million subscribers.1 As this number continues to increase, it is imperative for the supply side to be able to match consumer expectations. It is also important to ensure optimal usage of the spectrum to maximise economic benefits of this natural resource. So, as the government decides to release the presently unreleased spectrum, it should consider the overall economic impacts of the alternative strategies for re- leasing the spectrum. In this note, we consider the potential uses of both V-band (57 GHz - 64 GHz) and E-band (71 GHz - 86 GHz), as well as the economic benefits that may accrue from these uses. This analysis can help the government choose a suitable strategy for releasing spectrum in these bands.

  • DVB-H Planning with ICS Telecom
    2 White Paper July 2006 DVB-H radio-planning aspects in ICS telecom Coverage Emmanuel Grenier Spectrum : COFDM SFN / MFN Convergence – back channel Software solutions in radiocommunications 3 Abstract This white paper addresses the problem of efficient planning DVB-H networks with ICS telecom. This document is intended for radio-planner, technical director, project manager, consultant to be aware of the important goals to pursue when planning a DVB-H network. It focuses not only on macro-scale DVB-H planning and its analysis on the geo-marketing point of view, but also provides methodologies for deep-indoor network densification, at the address level. The suggested methodologies are divided into three topics: Defining the coverage model : o by defining the right threshold for a given service class; o by densifying the DVB-H network in dense urban areas. Enhancing the business model according to technical inputs : o analyzing the impact of the chosen coverage model on the population; o ensuring interactive/billing service by complementing the DVB-H network with a cellular infrastructure. Analyzing the impact of the integration of a DVB-H service in the existing spectrum, as well as checking the COFDM interference areas for SFN networks. 4 Table of Content 1 Acronyms ___________________________________________________________________ 1 2 Coverage aspects _____________________________________________________________ 2 2.1 Cartographic data ________________________________________________________ 2 2.1.1 Cartographic environment for Macro-scale

  • Design and Characterization of Meander Line Slow Wave Structures for W-Band Space Traveling Wave Tubes
    DESIGN AND CHARACTERIZATION OF MEANDER LINE SLOW WAVE STRUCTURES FOR W-BAND SPACE TRAVELING WAVE TUBES Juan M. Socuéllamos A thesis submitted to Lancaster University for the degree of Doctor of Philosophy Lancaster, United Kingdom April 2021 Declaration I declare that this thesis is my own work and has not been submitted in substantially the same form for the award of a higher degree elsewhere. Acknowledgement I would like to express my deepest gratitude to my supervisors at Lancaster Univer- sity, Prof. Claudio Paoloni and Dr. Rosa Letizia, for their expert guidance, constant support and understanding during the research and writing of this thesis. I would also like to thank my workmates there, specially Rupa Basu and Laxma R. Billa, for their friendship, wise advice and making this research more enjoyable. I am profoundly grateful to my supervisor at the European Space Agency, Mr. Roberto Dionisio, for supporting this research, giving me the opportunity to work with him and sharing his deep knowledge and valuable experience with me. Not to mention the excellent colleagues that I had the opportunity to meet at ESTEC and made my time there truly unforgettable. Last but not least, my wholeheartedly appreciation to my family and friends for their love, support and encouragement that made possible a successful completion of the PhD. Abstract Satellite communication systems are nowadays facing the growing demand of dif- ferent services such as internet, streaming or teleconferencing that consume a lot of resources and exhaust the available links. Increasing the frequency band of op- eration is becoming ever-more necessary to cope with the challenges of the future communication services.
