Synopsis

Presented in this book are essential design techniques for radiolinks in the point-to-point service operating the range of 1- 100 GHz. The general propagation in this frequency range is treated, along with the line-of-sight microwave/millimeter links, troposcatter/diffraction, and both analog and digital satellite systems. The text explains how radiolinks operate, how to size dimension terminals and ancillary subsystems and how to select the necessary performance parameters and equipment specifications to meet the needs of various customers. The seven chapters are organized progressively, each forming a background for subsequent chapters. Topics covered include radio propagation 1-100 GHz, line-of-sight radiolinks, over-the-horizon radiolinks, satellite communications analog systems, digital communications by satellite, system design above 10 GHz and a system approach to radio terminal design.

A propos du livre

Quatrième de couverture

Long the guidebook of telecommunication professionals, Radio System Design for Telecommunications is the definitive handbook of design and configuration of radiolinks in point–to–point telecommunications service as well as wireless and cellular systems. Offering clear technical insights on developing the overriding plan for a system as well as solving the minute problems usually encountered during the design process, Radio System Design is a comprehensive toolkit, full of practical theory on how radiolinks and wireless systems operate, as well as guidance on how to size or dimension terminals and ancillary subsystems and select the necessary performance parameters and equipment specifications to meet the needs of various radio users.

Updated and expanded for the newest wave in the telecommunications revolution, the Second Edition includes information on such ascendent technologies as cellular radio, personal communication systems (PCS), very small aperture terminal (VSAT) satellite communication networks, and meteor burst communications, as well as more established techniques such as troposcatter and high frequency (HF, 3–30 MHz) systems.

A growing phenomenon with an estimated 45 million users in the United States, cellular radio has become a vital part of our culture. This new edition examines key aspects of the technology as well as personal communications systems (PCS), an extension of cellular radio. With 120 million anticipated users by the year 2000, PCS has given rise to innovations such as Motorola′s exciting new IRIDIUM system, a satellite adjunct to cellular/PCS, also discussed.

VSAT systems, now viewed as an efficient, cost–effective alternative to leasing telephone company circuits, are fully discussed. The new edition also touches on code division multiple access (CDMA) and its promise of improved spectral usage as well as its ability to operate in high–interference environments and lessen multipath effects with both cellular and personal communication systems.

The book also examines key technical issues, essential to good design work:

• scintillation effects
• bandwidth requirements for digital radiolinks
• the penalties of not meeting "line–of–sight" conditions
• analysis of radio interference
• coordination contours
• jitter accumulation
• forward error correction
• advanced digital modulation waveforms
• dispersion on digital paths and its mitigation

Ideal for work in the field or a course of self–study, the book features end–of–chapter review questions and problems that enhance topical mastery. Throughout the text, key formulas are followed by at least one worked example. Also supplemented with a glossary of abbreviations and acronyms common to the industry as well as hundreds of illustrative tables, figures, and equations, the book is an exceptionally clear index of the latest technical innovations and jargon. Still the most authoritative handbook available for planning, engineering, and designing radiolinks and wireless systems in telecommunications, Radio System Design for Telecommunications, Second Edition is also an expansive and illuminating look at the global reach of these rapidly developing technologies.

As basic as a drafting tool to the design engineer, Radio System Design for Telecommunications has brought a clear, meticulously detailed approach to the task of designing radiolinks in point–to–point and point–to–point multipoint (wireless) telecommunications service. Containing technical fundamentals such as general propagation problems in a variety of transmission media, the book also offers real–world insights on siting criteria, hardware layout, facility planning, and frequency assignment.

This updated and expanded Second Edition describes the newest wave in the current telecommunications revolution, a world of such ascendent technologies as cellular radio, personal communication systems (PCS), very small aperture terminal (VSAT) satellite communication networks, and meteor burst communications, as well as more established techniques such as troposcatter and high frequency (HF, 3–30 MHz) systems.

Key technical issues, essential to good systems design work, are also examined:

• improved Eb/No versus BER curves
• jitter accumulation
• analysis of radio interference
• coordination contours
• bandwidth requirements for digital radiolinks
• scintillation effects

This new edition features end–of–chapter review questions and problems, a glossary of abbreviations and acronyms common to the industry, and hundreds of illustrative tables, figures, and equations. A practical, step–by–step blueprint to planning, engineering, and designing radiolinks in a communications system as well as a guide to anticipating and solving every sort of technical problem, Radio System Design for Telecommunications is the ultimate professional′s guide to understanding and using the technological toolkit of tomorrow.
