Wi-Fi Integration to the 4G Mobile Network

Summarizes and surveys current LTE technical specifications and implementation options for engineers and newly qualified support staff Concentrating on three mobile communication technologies, GSM, 3G-WCDMA, and LTE—while majorly focusing on Radio Access Network (RAN) technology—this book describes principles of mobile radio technologies that are used in mobile phones and service providers’ infrastructure supporting their operation. It introduces some basic concepts of mobile network engineering used in design and rollout of the mobile network. It then follows up with principles, design constraints, and more advanced insights into radio interface protocol stack, operation, and dimensioning for three major mobile network technologies: Global System Mobile (GSM) and third (3G) and fourth generation (4G) mobile technologies. The concluding sections of the book are concerned with further developments toward next generation of mobile network (5G). Those include some of the major features of 5G such as a New Radio, NG-RAN distributed architecture, and network slicing. The last section describes some key concepts that may bring significant enhancements in future technology and services experienced by customers.

An essential element of radio technology and propagation is how to use radio technology and knowledge of radio propagation to design a network that meets the needs of customers. Mobile Radio Network Design in the VHF and UHF Bands provides the technical and fundamental knowledge required for advanced mobile radio network design to achieve this in terms that the engineer will understand, and augments this with essential information gleaned from the authors' extensive experience in mobile radio network design. In this book you will find out how some of the most highly-regarded radio network designers around go about designing radio networks that actually meet the needs of the network subscriber and of the network operator. It describes a well-proven framework that meets the essential need of ensuring that each step of the design project is carried out against known, unique and unambiguous requirements, and that these requirements have been extensively validated against the original requirements. Reveals the secrets behind coverage design, capacity planning, interference analysis and reduction, frequency assignment and verifying that the delivered network actually performs as promised Introduces the concept of documentary deliverables as part of the project and underlines the need for method statements, user requirement, functional, test and design specifications Provides readers with a far greater understanding of the methods and processes necessary to bring about the successful completion of a radio network project Highlights vital aspects of radio network projects that are not always apparent to every engineer, but which may have a vital impact on the success of the project The powerful approach used in this book will help to ensure the successful completion of every project and will be the basis for ensuring contractual compliance at every stage. It is an indispensable resource for all radio network design consultants and engineers, network operator technical managers, radio regulation engineers and military radio network planners.

Efficient, compliant management systems pave the road to sustainability through integration and automation The book addresses the many definitions of sustainability and why CEOs need the links between sustainability, business value, and performance. Business leaders are committed to leading the way, and the book outlines the support of a management system structure and business principles that will drive the accomplishment of their mission. Stakeholder demands on CEOs include many challenges. Investors are assessing companies for financial performance. The shrinking talent pool of employees is looking to work with organizations that support social, environment, and economic operating practices and principles. Great leaders are those that ask questions, who are creative to drive innovation for growth of their company. The Assess-Reflect-Act section on international business principles defined in the book will ask you as the leader thought provoking questions to stimulate action within your organization to bring people, processes, and technology together for business success. Leaders need to transition to smart decisions that are data driven. The company's management system structure is important to build a strong framework for business process operations and automation for global competitiveness. Topics include: Business plans vs management systems Management system frameworks: standardization, ISO standards: Quality – ISO 9001, Environment – ISO 14001, OHSAS 18001, Integrated Management Systems Three Steps for Process Development: Identify, Insure, Improve Focus for the Organization: Compliance Costs, Best Practices, Strategic Planning Support – Resources: Innovation, Engagement, Succession Planning Data as a Valuable Resource Operation: Process Risks, Management System Control Plan, E-commerce, Enterprise Resource Planning (ERP), Green Awareness-Eco Design, Automated Controls, Cloud Computing Performance Evaluation – Monitor, Measure, Analyze, Audit, Management Review Competitive Landscape The constant need to improve internal processes and move toward business sustainability and quality standards is a major stressor for governments and businesses. With one-third of the workforce retiring in the next five to ten years, the need has become more immediate, and the focus has shifted to building a strong framework for business process operations and automation for global competitiveness. This book provides a roadmap to efficient, compliant systems, showing businesses how to build toward sustainability goals and capture key knowledge of the employees involved in the process.

An accessible, clearly organized survey of the basic topics of measure theory for students and researchers in mathematics, statistics, and physics In order to fully understand and appreciate advanced probability, analysis, and advanced mathematical statistics, a rudimentary knowledge of measure theory and like subjects must first be obtained. The Theory of Measures and Integration illuminates the fundamental ideas of the subject-fascinating in their own right-for both students and researchers, providing a useful theoretical background as well as a solid foundation for further inquiry. Eric Vestrup's patient and measured text presents the major results of classical measure and integration theory in a clear and rigorous fashion. Besides offering the mainstream fare, the author also offers detailed discussions of extensions, the structure of Borel and Lebesgue sets, set-theoretic considerations, the Riesz representation theorem, and the Hardy-Littlewood theorem, among other topics, employing a clear presentation style that is both evenly paced and user-friendly. Chapters include: * Measurable Functions * The Lp Spaces * The Radon-Nikodym Theorem * Products of Two Measure Spaces * Arbitrary Products of Measure Spaces Sections conclude with exercises that range in difficulty between easy «finger exercises»and substantial and independent points of interest. These more difficult exercises are accompanied by detailed hints and outlines. They demonstrate optional side paths in the subject as well as alternative ways of presenting the mainstream topics. In writing his proofs and notation, Vestrup targets the person who wants all of the details shown up front. Ideal for graduate students in mathematics, statistics, and physics, as well as strong undergraduates in these disciplines and practicing researchers, The Theory of Measures and Integration proves both an able primary text for a real analysis sequence with a focus on measure theory and a helpful background text for advanced courses in probability and statistics.
