Languages : en
Pages : 206

Book Description
What debates have caused spectrum policy to change course, and which will determine its future direction? This book examines these issues through a series of essays from a range of notable experts. The backdrop is a period of turbulent change in what was once a quiet backwater. The past quarter century has seen wireless connectivity go from nice-to-have luxury to the cornerstone of success as nations battle for leadership of the digital economy. The change has been reflected in the crucial role now played by markets mechanisms in a field once dominated by administrative decisions. Spectrum policy's goals have moved far beyond the efficient use of the airwaves to include encouraging economic development, investment, innovation, sustainability and digital inclusivity. Are historic procedures still appropriate in the face of this multiplicity of demands? Are market mechanisms like auctions still the best way to deliver what has become essential infrastructure? Does the process of international co-ordination need to change? Is spectrum policy's effectiveness limited by the power of global economic forces? Can it reduce rather than add to global warming? Where does 6G and AI fit in? Is public perception the new spectrum policy battle ground? These are all issues examined in The debates shaping spectrum policy.

Spectrum Sharing in Wireless Networks

Spectrum Sharing in Wireless Networks PDF Author: John D. Matyjas
Publisher: CRC Press
ISBN: 1498726364
Category : Computers
Languages : en
Pages : 706

Book Description
Spectrum Sharing in Wireless Networks: Fairness, Efficiency, and Security provides a broad overview of wireless network spectrum sharing in seven distinct sections: The first section examines the big picture and basic principles, explaining the concepts of spectrum sharing, hardware/software function requirements for efficient sharing, and future trends of sharing strategies. The second section contains more than 10 chapters that discuss differing approaches to efficient spectrum sharing. The authors introduce a new coexistence and sharing scheme for multi-hop networks, describe the space-time sharing concept, introduce LTE-U, and examine sharing in broadcast and unicast environments. They then talk about different cooperation strategies to achieve mutual benefits for primary users (PU) and secondary users (SU), discuss protocols in a spectrum sharing context, and provide different game theory models between PUs and SUs. The third section explains how to model the interactions of PUs and SUs, using an efficient calculation method to determine spectrum availability. Additionally, this section explains how to use scheduling models to achieve efficient SU traffic delivery. The subject of the fourth section is MIMO-oriented design. It focuses on how directional antennas and MIMO antennas greatly enhance wireless network performance. The authors include a few chapters on capacity/rate calculations as well as beamforming issues under MIMO antennas. Power control is covered in the fifth section which also describes the interference-aware power allocation schemes among cognitive radio users and the power control schemes in cognitive radios. The sixth section provides a comprehensive look at security issues, including different types of spectrum sharing attacks and threats as well as corresponding countermeasure schemes. The seventh and final section covers issues pertaining to military applications and examines how the military task protects its data flows when sharing the spectrum with civilian applications.

Broadband In Brazil

Broadband In Brazil PDF Author: Peter Knight
Publisher: Google Access
ISBN: 8567871786
Category : Technology & Engineering
Languages : en
Pages :

Book Description
The Internet has been a reality in Brazil for more than 20 years. Its growth has been encouraged by the government, by large telecom companies, and by small and medium Internet service providers, as well as by rapidly increasing demand. The achievements to date are clear, but almost half the population is still not participating in the digital world. Furthermore, the cost of broadband is still high and its quality should be improved so that it will be possible to take advantage of all the benefits it can bring, whether related to health, education, or even the exercise of political rights. It is necessary, therefore that the Brazilian Internet be fast, reliable, and accessible. This book brings together 23 specialists in various areas related to broadband, specialists who wanted to discuss Brazil’s public policies and regulations as well as the progress and challenges related to expanding access to broadband Internet service. The 16 chapters also address the evolution of the country’s broadband infrastructure, including experiences of entrepreneurship and public-private partnerships. This debate is fundamental for Brazil’s technological, economic and social progress.

Frequencies

Frequencies PDF Author: Gregory Taylor
Publisher: McGill-Queen's Press - MQUP
ISBN: 0228003121
Category : Political Science
Languages : en
Pages : 318

Book Description
Our digital world is increasingly mobile. All mobile communication rests upon access to one invisible, essential element: the radio spectrum. In Frequencies Gregory Taylor and Catherine Middleton bring together diverse national perspectives to explore the current and future state of spectrum governance worldwide. Spectrum is a foundational component of our contemporary communication infrastructure. The stakes are massive: mobile network operators have invested billions of dollars via national spectrum auctions to claim exclusive use of prime spectrum bands. Despite this windfall for national governments, many people around the globe remain disconnected from mobile service, yet international policy comparisons that can help us understand these disparities and differences are rare. Frequencies offers illuminating case studies from around the world, including Finland, Mexico, New Zealand, India, and Canada, as well as forward-thinking approaches to our use of radio frequencies that encourage greater public benefit and technological advancement. The contributors to Frequencies represent a wide array of disciplinary backgrounds, united by the common goal of maximizing the value and access to the public good that is the radio spectrum. Spectrum policy affects everyone, whether while listening to the radio, making an emergency phone call, or scrolling through social media updates. Frequencies seeks to broaden the discussion about our management of this primary resource necessary for how the world shares information.

Technology, Sovereignty and International Law

Technology, Sovereignty and International Law PDF Author: Francis Lyall
Publisher: Routledge
ISBN: 1000553760
Category : Law
Languages : en
Pages : 240

Book Description
The dogma of the sovereignty of the state, deriving from the Peace of Westphalia, underpins much of the modern-day international system. However, developments in recent technology have led this ideology to depart from reality. Viewing state sovereignty through the prism of public international law, the book will begin with an overview of the settlement of Westphalia, how it has influenced international documents ever since, and how the advantages of centralised decisions came to be perceived. By surveying the Law of the Sea, Maritime Law, Air and Aviation, Telecommunications, Postal Services, Space Law and Mensuration, the book demonstrates how, in each, the interplay between state sovereignty and developing technologies have caused significant legal change. Some changes, Lyall argues, such as international measures of time and geography, have been born out of convenience, facilitated by technology developed for the purpose. Other areas of change developed out of a desire to reconcile conflicts or harmonise necessary state regulation. The book analyses the reasons behind these changes, and discusses the ongoing attempts to balance state equality, measures adopted by new institutions to secure comprehensive representation, and ends by looking to the future of state sovereignty in an increasingly globalised world. The book is of use to any student or scholar interested in policy making, international law and international affairs, both legal and scientific, as well as those looking at legal administrative issues and government officiation.

The International Radio Regulations

The International Radio Regulations PDF Author: Mohamed Ali El-Moghazi
Publisher: Springer Nature
ISBN: 3030885712
Category : Science
Languages : en
Pages : 222

Book Description
This book provides an in-depth introduction to the International Telecommunication Union (ITU) Radio Regulations (RR) and the policies that govern them. Established in 1906, these regulations define the allocation of different frequency bands to different radio services, the mandatory technical parameters to be observed by radio stations, especially transmitters, and the procedures for spectrum use coordination at the international level. The book analyzes the interactions between different national policies and the ITU RR, noting how these interactions influence spectrum policy on the national level, setting up a comparative framework within which to view these regulations and their effects. Beginning with an overview of the history of the origins ITU RR, the book takes a deep dive into the components of spectrum management including radio communication service allocation, wireless technology selection, radio usage rights, and spectrum rights assignment, placing each analysis within the context of the push and pull between national and international regulations. The book concludes with chapters discussing issues affecting the future of spectrum policy, including spectrum policy reform in developing countries, the WRC-19, and IMT-2020. Shedding light on the longest-running treaty documents in the history of modern telecommunications and arguing for reforms that allow it to address the needs of all nations, this book is useful to scholars and students of telecom policy, digital policy, ICT, governance, and development as well as telecom industry practitioners and regulators.
