Using numerous practical examples,this book examines the evolution of EC telecommunications law following the achievement of liberalisation, the main policy goal of the 1990s. After reviewing the development of regulation in the run-up to liberalisation, the author identifies the methods used to direct the liberalisation process and tests their validity in the post-liberalisation context. A critical analysis is made of the claim that competition law will offer sufficient means to regulate the sector in the future. Particular emphasis is given to the way in which EC Competition Law changed in the 1990s using the essential facilities doctrine, an expansive non-discrimination principle and the policing of cross-subsidisation to tackle what were then thought of as regulatory matters. Also examined within the work is the procedural and institutional interplay between competition law and telecommunications regulation. In conclusion, Larouche explores the limits of competition law and puts forward a long-term case for sector-specific regulation, with a precise mandate to ensure that the telecommunications sector as a whole fulfils its role as a foundation for economic and social activity.

Design of Digital Phase Shifters for Multipurpose Communication Systems aims to cover a new emerging need in designing digital phase shifters for modern communication systems. With the advancement of new generation mobile communication systems, directed beams save a substantial amount of RF-power, and improve the noise immunity. In this regard, beam-forming circuits, namely, digital phase shifters constitute essential parts the antenna arrays. Therefore, this book is devoted to design of digital phase shifters for various communications systems. In the good old days, phase shifter design requirements used to demand narrow bandwidth with no physical size constraints. Nowadays, they must be compact and suitable for Very Large Scale Integrated Circuits (VLSI) or Microwave Monolithic Integrated Circuit (MMIC) implementation with Wide Phase Range (WPR) and Wide Frequency Band (WFB). Since the 1980s, the author has been designing digital phase shifters for various applications. He started to work with loaded lines phase shifters, and then employed branch line couplers to achieve wider frequency bands. In order to reduce the physical size, he used a 3 element Symmetric LC ladder based T or PI configurations. In order to achieve broad frequency band with large phase range, usage of LC lattice structures is inevitable. Lately, the author designed phase shifters using both lowpass and highpass LC ladder and lattice based switched-structures, which are suitable for monolithic implementation. In the course of design, MOS transistors were employed as switching elements. This book includes several novel digital phase shifter topologies, which provides wide phase range and wideband operation. Technical topics discussed in the book include:- Basic Concept of Antenna Arrays- Concept of Digital Phase Bit- Scattering Parameters to analyze the electric performance of phase shifters- Transmission Lines as circuit elements to construct practical phase shifters- Loaded Line Digital Phase Shifters (DPS)- Lowpass Based T/PI Section DPS- Highpass Based T/PI Section DPS- 3-Element LC T/PI Section DPS- Wide Phase Range, Wide Frequency Band Symmetric Lattice Based DPS For each topology presented, explicit design equations are provided and programs to assess the electric performance of each topology is developed in a MatLab environment. It is expected that the reader will be self-sufficient to design and implement the digital phase shifters topologies presented in this book.

Mobilizing the Information Society comprehensively and critically examines the interaction between social, regulatory, and market developments underlying the growing use of new technologies such as the personal computer and the Internet. Based upon empirical research by an international team, it offers insights needed to understand public policy, corporate strategy, and individual choices taken in response to the deluge of new technological opportunities. A principal theme of Mobilizing the Information Society is that changes are governed by public decisions that establish the institutional framework in which the private sector operates. The quality and value of the information society for the citizen is not the inevitable consequence of market and technological forces. Policy choices, however, that fail to take market and technical influences into account will prove ineffective. The authors lay the foundation for improved theories of the process of change, more appropriate strategies to achieve desired aims, and more effective policies for mitigating the effects of dislocation and exclusion from the information society. Mobilizing the Information Society offers unique insights into the social, economic, and political forces that are structuring the pathway to the information society, and their consequences for businesses and citizens in their everyday lives.

Within a few short years, fiber optics has skyrocketed from an interesting laboratory experiment to a billion-dollar industry. But with such meteoric growth and recent, exciting advances, even references published less than five years ago are already out of date. The Fiber Optics Illustrated Dictionary fills a gap in the literature by providing instructors, hobbyists, and top-level engineers with an accessible, current reference. From the author of the best-selling Telecommunications Illustrated Dictionary, this comprehensive reference includes fundamental physics, basic technical information for fiber splicing, installation, maintenance, and repair, and follow-up information for communications and other professionals using fiber optic components. Well-balanced, well-researched, and extensively cross-referenced, it also includes hundreds of photographs, charts, and diagrams that clarify the more complex ideas and put simpler ideas into their applications context. Fiber optics is a vibrant field, not just in terms of its growth and increasing sophistication, but also in terms of the people, places, and details that make up this challenging and rewarding industry. In addition to furnishing an authoritative, up-to-date resource for relevant industry definitions, this dictionary introduces many exciting recent applications as well as hinting at emerging future technologies.
