If you need to maximize efficiency in wireless network planning, an understanding of radio propagation issues is vital, and this 2007 reference guide is for you. Using real-world case studies, practical problems and minimum mathematics, the author explains simply and clearly how to predict signal strengths in a variety of situations. Fundamentals are explained in the context of their practical significance. Applications, including point-to-point radio links, broadcasting and earth-space communications, are thoroughly treated, and more sophisticated methods, which form the basis of software tools for both network planning and spectrum management, are also described. For a rapid understanding and insight into radio propagation, sufficient to enable you to undertake real-world engineering tasks, this concise book is invaluable for network planners, hardware designers, spectrum managers, senior technical managers and policy makers who are either new to radio propagation or who need a quick reference guide.

This work treats the essential elements of radio wave propagation without requiring recourse to advanced electromagnetic concepts and equations. However, it provides sufficient detail to allow those concerned with wireless systems to acquire quickly a practical working knowledge of the important concepts. Radio wave propagation is placed in a practical context by considering the design aspects of communications systems at microwave frequencies. A fuller consideration of the electromagnetic properties of materials is given late in the book rather than as an introductory chapter.

An accessible student-oriented approach to radiowave propagation Propagation-the process whereby a signal is conveyed between transmitter and receiver-has a profound influence on communication systems design. Radiowave Propagation provides an overview of the physical mechanisms that govern electromagnetic wave propagation in the Earth's troposphere and ionosphere. Developed in conjunction with a graduate-level wave propagation course at The Ohio State University, this text offers a balance of physical and empirical models to provide basic physical insight as well as practical methods for system design. Beginning with discussions of propagation media properties, plane waves, and antenna and system concepts, successive chapters consider the most important wave propagation mechanisms for frequencies ranging from LF up to the millimeter wave range, including: Direct line-of-sight propagation through the atmosphere Rain attenuation The basic theory of reflection and refraction at material interfaces and in the Earth's atmosphere Reflection, refraction, and diffraction analysis in microwave link design for a specified terrain profile Empirical path loss models for point-to-point ground links Statistical fading models Standard techniques for prediction of ground wave propagation Ionospheric propagation, with emphasis on the skywave mechanism at MF and HF and on ionospheric perturbations for Earth-space links at VHF and higher frequencies A survey of other propagation mechanisms, including tropospheric scatter, meteor scatter, and propagation effects on GPS systems Radiowave Propagation incorporates fundamental materials to help senior undergraduate and graduate engineering students review and strengthen electromagnetic physics skills as well as the most current empirical methods recommended by the International Telecommunication Union. This book can also serve as a valuable teaching and reference text for engineers working with wireless communication, radar, or remote sensing systems.

Based on his many years of professional experience at leading companies in communications technology, the author describes an analytical solution for wave propagation over the sea surface in an atmospheric boundary layer. His approach allows the detailed analysis of combined effects of diffraction, refraction and scattering in random media. While specific applications covered are targeted at radio wave propagation over the sea surface, a similar approach is applicable to many problems in underwater acoustics, seismology, solid matter physics and astrophysics.

The anomalous nighttime propagation of radio waves was studied at frequencies of 9100, 2800, and 840 Mc/s observed on the 108-km path from Rochester to Ithaca, New York. Previously proposed theories that explain anomalous propagation by ducting, reflection, or diffraction fail to explain the irregular behavior studied. Further radio measurements in the form of (1) sampling the 9100-Mc/s signal at 15 sites located along the propagation path, (2) heightgain measurements at 9100 Mc/s at the receiver site, and (3) swinging the 2800-Mc/s antennas 2 deg off the great circle path were undertaken in order to arrive at an explanation of the phenomenon. Finally, a theory based on the formation of elevated superrefractive layers situated over two lakes crossing the path is proposed to explain the anomalous propagation. (Author).

Parabolic equation methods, used to analyze radiowave propagation in radar and radio communication systems, have become the dominant tool for assessing clear-air and terrain effects on propagation. This volume introduces the mathematical background to parabolic equation modelling and describes simple parabolic equation algorithms before progressing to more advanced topics, including domain truncation, impedance boundaries and the implementation of fast hybrid methods combining ray-tracing and parabolic equation techniques. The text's self-contained approach is suited to graduate students and researchers with little experience of radiowave propagation.

Both the efficacy and accuracy of existing algorithms for predicting radiowave coverage are often compromised for the region proximate to the ground surface where grazing incidence (and wave cancellation) occurs, surface wave propagation predominates, and intricate higher order reflection and diffraction phenomena become important. A challenge of ongoing interest is to develop high-fidelity electromagnetic models that can reliably evaluate wave interaction with a realistic terrain over long distances with the inclusion of ground proximity effects---in order to support channel performance assessment and grid planning of near-ground (or even sub-surface) communication systems and sensing-oriented networks. In the featured study, physics-based propagation models enabling accurate calculation of propagation path-loss among the nodes of the VHF (30 MHz--300 MHz) near-earth wireless system deployed in natural scenes are assembled through a compilation of analytical, numerical, experimental, and hybrid approaches. Wave propagation issues and their physical interpretations pertinent to the modeling of assorted terrain conditions are presented within the scope of the following: (1) Demonstration of the relevancy and significance of various types of surface waves defining near-grazing radiowave interactions with a dielectrically-covered terrain through the derivation of second order asymptotic solutions. (2) Treatment of the diffraction effect of a vegetation layer discontinuity using Kirchhoff-Huygens approach and validation of obtained results with measurements from an experimental setup. (3) Simulation of long-distance propagation over undulating terrain surfaces with a high order numerical solver achieving accurate solutions with as few as one unknown per linear wavelength for highly rough profiles (rms slope up to 15°). (4) Characterization of ground wave propagation over random rough surfaces with closed-form effective, near-grazing reflection coefficients formulated from an existing volumetric polarization current-based perturbation approach. (5) Performance analysis and comparison of low-profile, near-ground radiating structures with a hybrid modeling technique.
