Description
Published in 2012 exclusively in France, this English translation of Antennas and Site Engineering for Mobile Radio Networks is the first book to discuss the specific antennas used in both commercial (2G, 3G, 4G) and private mobile radio (PMR) networks. These are the antennas located on pylons in rural areas and tubular masts on rooftops in urban areas. This book presents essential information for engineers, managers, and technicians working for mobile phone equipment manufacturers, network integrators, and antenna installation companies. This resource is divided into three sections: the first section describes the functioning of specific types of antennas used in mobile phone networks and provides examples of each; the second section provides a detailed exploration of antenna site engineering, which is crucial to the quality of mobile networks; and the third section includes refresher information on the mathematics and physics necessary to understand the content of the book and put it to practical use in actual applications. This book is packed with clear explanations and recommendations to help antenna professionals avoid problems and make the best antenna and site decisions.
