The "Second Edition" of this critically-acclaimed text continues the standard of excellence set in the first edition by providing a thorough introduction to the fundamentals of telecommunication networks without bogging you down in complex technical jargon or math. Although focusing on the basics, the book has been thoroughly updated with the latest advances in the field, including a new chapter on metropolitan area networks (MANs) and new sections on Mobile Fi, ZigBee and ultrawideband. You'll learn which choices are now available to an organization, how to evaluate them and how to develop strategies that achieve the best balance among cost, security and performance factors for voice, data, and image communication.

An Instructor's Manual presenting detailed solutions to all the problems in the book is available from the Wiley editorial department.

Complete coverage of data communication network design for IT specialists

Effective data communication is vital to modern businesses. Whether sending data over short or long distances, speed, simplicity, and efficiency are of paramount importance. This new, fully updated Second Edition of Practical Data Communications is an indispensable guide for IT managers, computer scientists, system engineers, or any professional who must design or maintain data communication networks. Professionals will find it useful as a reference for precise terminology, applications, and practices in the field. The book stresses explanation and concepts rather than theory, with current practice as the underlying theme.

Roger Freeman emphasizes generalized data networks and their protocols, rather than limiting the scope of the work by concentrating on proprietary systems. While most resources in the field forgo description of the underlying digital network, discussion of PSTN as well as SONET and SDH is included here in order to allow readers to better take advantage of services available from the public network. Other sections feature discussions of:

• Fiber-optic transmission
• ATM and IP
• Frame Relay
• LANs and WANs
• Last mile broadband
• Gigabit Ethernet

Written to facilitate an understanding of data communications that emphasizes practical applications rather than theory, Practical Data Communications, Second Edition serves as an excellent tutorial for students or professionals with only basic understanding of the subject.

Step-by-step tutorial to master current design techniques for wireless communication systems

The Third Edition of "Radio System Design for Telecommunications" brings this highly acclaimed book fully up to date with the latest technological advances and new applications. At the same time, the hallmarks of the previous editions, including the text's popular tutorial presentation, have been retained. Readers therefore get all the tools and guidance they need to master an essential set of current design techniques for radio systems that operate at frequencies of 3 MHz to 100 GHz.

Using simple mathematics, the author illustrates design concepts and applications. The book's logical organization, beginning with a discussion of radio propagation problems, enables readers to progressively develop the skills and knowledge needed to advance in the text. Topics that are new to the Third Edition include: Chapter devoted to wireless LANs (WLANs) as detailed in IEEE 802.11Subsections covering IEEE 802.15, 802.16, 802.20, and the wireless metropolitan area network (WMAN)WiFi, WiMax, and UWB applications that have recently experienced explosive growthBroadband radio in telecommunications, as well as offset frequency division multiplex (OFDM), a new technique for transmitting information in an interference environmentThe use of very small aperture satellite terminal (VSAT) systems as an economical alternative to public switched telecommunication networks (PSTN)

Review questions and problems at the end of each chapter engage readers' newfound skills and knowledge and help them assess whether they are ready to progress to the next chapter. References are provided for readers who want to investigate particular topics in greater depth.

Students in wireless telecommunications will find the book's tutorial style ideal for learning all the ins and outs of radio system design, whereas professionals in the industry will want to refer to the Third Edition for its clear explanations of the latest technology and applications.

A text that sheds much-needed light on one of telecommunication’s brightest technologies

Fiber optics has assumed a dominant place among the available technologies to slake the ever-growing worldwide thirst for bandwidth. As miles and miles of optical fiber cable is being buried underground and under the sea, the demand for those capable of designing and installing fiber-optic systems has also grown. This book gathers all the essential information needed by the network architects, engineers, and craftspeople who plan, install, and maintain fiber-optic systems.

Requiring only a basic math and physics background, Fiber-Optic Systems for Telecommunications acts as both a tutorial and practical reference on both theory and practical applications.

It discusses:

• Loss-limited and dispersion-limited fiber links
• Optical networking
• Availability and survivability of fiber-optic networks
• Dense wave-division multiplexing (DWDM)
• Light transmission impairments, including Brillioun scattering, Raman scattering, four-wave mixing, polarization mode dispersion (PMD), and other non-linear effects
• Hybrid fiber-coax CATV networks
• Fiber-optic link budgets and tradeoffs

The text stresses design methods for achieving advanced performance on fiber-optic systems inside cost-effective limits. At the same time, a good dose of practical application is provided to the reader. For example, there is an extensive section on the application of an OTDR (optical time domain reflectometer) for performance measurement and troubleshooting of optical systems.

The book examines the maximum capacity of high-quality single-mode fiber. Here, the ITU has made some major contributions in this arena in their G.650 and G.950 recommendations. The author describes the ITU "grid" or wavelength assignment chart for the 1550 nm band. How close can these light carriers be placed before serious performance degradation occurs? He describes ultimate bit rate capacity in this band alone in the hundred of terabits reaching a final bit rate capacity possibly in the low thousands of terabits per second. The author communicates the excitement of such research in his writing.

A complete hands-on guide to designing and implementing all types of telecommunications transmission systems.

For more than 23 years, Telecommunications Transmission Handbook has been the guide to designing and building telecommunications transmission systems and the reference of choice among a generation of communications engineers and technicians. Its total systems approach examines each telecommunications transmission specialty as an integral part of a larger system. This book constructs a framework for understanding and exploiting the ways in which each telecommunications specialty affects all the others. It provides:

• Clear, methodical delineation of key principles, theories, and concepts
• Lucid explanations of cutting-edge design methodologies
• Comprehensive coverage of new and emerging technologies
• Step-by-step instructions on how to design and implement all types of telecommunications links, systems, and subsystems.

Following in this tradition, this Fourth Edition is fully updated to include coverage of important recent developments in telephone transmission, digital networks, microwave systems, radio systems, VSAT networks, meteor burst communication, fiber optics, and more. It also features entirely new chapters on cellular and wireless communication systems, cable and digital television, and low Earth-orbiting satellites.

A senior life member of the IEEE, Roger Freeman has lectured at numerous professional conferences and published widely in international telecommunications journals. He gives telecommunications seminars at the University of Wisconsin, Madison.
