A 2007 guide to understanding radio propagation issues for practitioners working in wireless communications, antennas and propagation.If you need to maximize efficiency in wireless network planning, this 2007 guide to understanding radio propagation issues is for you. Using real-world case studies, practical problems and minimum mathematics this is an invaluable resource for network planners, hardware designers, spectrum managers, senior technical managers and policy makers.If you need to maximize efficiency in wireless network planning, this 2007 guide to understanding radio propagation issues is for you. Using real-world case studies, practical problems and minimum mathematics this is an invaluable resource for network planners, hardware designers, spectrum managers, senior technical managers and policy makers.If you need to maximize efficiency in wireless network planning, this quick reference guide to an increasingly complex and difficult topic 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. More sophisticated methods, which form the basis of software tools for both network planning and spectrum management, are also described. This will be an invaluable resource for network planners, hardware designers, spectrum managers, senior technical managers and policy makers.Preface; 1.
