The field of radio communications continues to change rapidly, and the second edition of this outstanding book, based on a popular IEE Vacation School, has been fully updated to reflect the latest developments. The introduction of new services and the proliferation of mobile communications have produced a growing need for wider bandwidths and the consequent need for frequency reuse. This book introduces the basic concepts and mechanisms of radiowave propogation engineering in both the troposphere and ionosphere, and includes greater emphasis on the needs of digital technologies and new kinds of radio systems. The content reflects the wide experience of an exceptional group of authors and the emphasis throughout is on modelling and prediction methods and the relevant ITU Radiocommunication Sector recommendations. Propagation of Radiowaves, 2nd Edition is essential reading for professionals involved in planning, designing and operating radio systems, as well as postgraduate students in the field.

Propagation of Radiowaves introduces the basic concepts and mechanisms of radiowave propagation engineering in both the troposphere and ionosphere, an understanding of which is fundamental to the effective use of the radio spectrum for radiocommunication. Reflecting the wide experience of the exceptional group of authors, the contents provide a firm background to established theory and introduce the most appropriate models, methods and procedures which are of use to spectrum planners, system designers and operators in assessing the estimated performance of radio systems.The field of radio communications continues to change rapidly and the third edition of this outstanding and successful book has been fully updated to reflect the latest developments. The relevant Recommendations of ITU-R Study Group 3 are discussed and put into context.Propagation of Radiowaves, 3rd Edition is essential reading for professionals involved in the planning, design and operation of radio systems, as well as academics and postgraduate students in the field.
