This newly revised edition of the classic Artech House book, Microwave Radio Transmission Design, provides a current, comprehensive treatment of the subject with a focus on applying practical knowledge to real-world networks. The second edition includes a wealth of important updates, including discussions on backhaul capacity limitations, ethernet over radio, details on the latest cellular radio standards (2.5G, 3G, and 4G). You also learn about recent changes in spectrum management, including the availability of unlicensed bands and new mm band frequencies between 70 and 90 GHz. Additionally, you find more details on the fundamentals of antennas, especially at VHF/UHF levels. Written in an easy-to-understand style, the author provides practical guidelines based on hands-on experience. You find valuable assistance in designing and planning SDH/SONET broadband networks, wireless local loop networks, and backhaul for mobile radio networks. Moreover, this authoritative volume covers frequency planning for radio networks, digital radio equipment characteristics, |

Sommario/riassunto |
|
This book, authored by Wilhelm Gehlhoff and edited by Arthur Spiethoff, investigates the influence of gold production on price formation between 1890 and 1913. It is part of the series 'Schriften des Vereins für Sozialpolitik' focused on price formation. The book examines the general price movement during this period, delving into the impact of new gold production on global economic factors such as money prices and goods. The study covers various regions including Russia, America, Australia, and South Africa, analyzing how gold production affected local economies and global trade. The work was delayed due to the outbreak of World War I, which impacted the completion of several studies within the series. The intended audience includes economists and scholars interested in historical economic trends and the role of commodity production in price dynamics. |
