This practical handbook and reference provides a complete understanding of the telecommunications field supported by descriptions and case examples throughout Taking a practical approach, The Telecommunications Handbook examines the principles and details of all of the major and modern telecommunications systems currently available to industry and to end-users. It gives essential information about usage, architectures, functioning, planning, construction, measurements and optimisation. The structure of the book is modular, giving both overall descriptions of the architectures and functionality of typical use cases, as well as deeper and practical guidelines for telecom professionals. The focus of the book is on current and future networks, and the most up-to-date functionalities of each network are described in sufficient detail for deployment purposes. The contents include an introduction to each technology, its evolution path, feasibility and utilization, solution and network architecture, and technical functioning of the systems (signalling, coding, different modes for channel delivery and security of core and radio system). The planning of the core and radio networks (system-specific field test measurement guidelines, hands-on network planning advices and suggestions for the parameter adjustments) and future systems are also described. Each chapter covers aspects individually for easy reference, including approaches such as: functional blocks, protocol layers, hardware and software, planning, optimization, use cases, challenges, solutions to potential problems Provides very practical detail on the planning and operation of networks to enable readers to apply the content in real-world deployments Bridges the gap between the communications in the academic context and the practical knowledge and skills needed to work in the telecommunications industry Section divisions include: General theory; Fixed telecommunications; Mobile communications; Space communications; Other and special communications; and Planning and management of telecommunication networks Covers new commercial and enhanced systems deployed, such as IPv6 based networks, LTE-Advanced and GALILEO An essential reference for Technical personnel at telecom operators; equipment and terminal manufacturers; Engineers working for network operators.

Interconnecting Smart Objects with IP: The Next Internet explains why the Internet Protocol (IP) has become the protocol of choice for smart object networks. IP has successfully demonstrated the ability to interconnect billions of digital systems on the global Internet and in private IP networks. Once smart objects can be easily interconnected, a whole new class of smart object systems can begin to evolve. The book discusses how IP-based smart object networks are being designed and deployed. The book is organized into three parts. Part 1 demonstrates why the IP architecture is well suited to smart object networks, in contrast to non-IP based sensor network or other proprietary systems that interconnect to IP networks (e.g. the public Internet of private IP networks) via hard-to-manage and expensive multi-protocol translation gateways that scale poorly. Part 2 examines protocols and algorithms, including smart objects and the low power link layers technologies used in these networks. Part 3 describes the following smart object network applications: smart grid, industrial automation, smart cities and urban networks, home automation, building automation, structural health monitoring, and container tracking. Shows in detail how connecting smart objects impacts our lives with practical implementation examples and case studies Provides an in depth understanding of the technological and architectural aspects underlying smart objects technology Offers an in-depth examination of relevant IP protocols to build large scale smart object networks in support of a myriad of new services

Mutual-fund superstar Peter Lynch and author John Rothchild explain the basic principles of the stock market and business in an investing guide that will enlighten and entertain anyone who is high-school age or older. Many investors, including some with substantial portfolios, have only the sketchiest idea of how the stock market works. The reason, say Lynch and Rothchild, is that the basics of investing—the fundamentals of our economic system and what they have to do with the stock market—aren’t taught in school. At a time when individuals have to make important decisions about saving for college and 401(k) retirement funds, this failure to provide a basic education in investing can have tragic consequences. For those who know what to look for, investment opportunities are everywhere. The average high-school student is familiar with Nike, Reebok, McDonald’s, the Gap, and the Body Shop. Nearly every teenager in America drinks Coke or Pepsi, but only a very few own shares in either company or even understand how to buy them. Every student studies American history, but few realize that our country was settled by European colonists financed by public companies in England and Holland—and the basic principles behind public companies haven’t changed in more than three hundred years. In Learn to Earn, Lynch and Rothchild explain in a style accessible to anyone who is high-school age or older how to read a stock table in the daily newspaper, how to understand a company annual report, and why everyone should pay attention to the stock market. They explain not only how to invest, but also how to think like an investor.
