商品簡介
This work combines a theoretical treatise of radio theory and standards with practical recommendations and case studies in planning and deploying modern digital microwave radio systems from UHF up to the millimeter bands. Chapters cover link planning, reliability standards, transport technologies, radio equipment characteristics, microwave propagation, antenna considerations, frequency planning, and link design. With the first edition published in 1999, this second edition is updated with discussions on backhaul capacity limitations, ethernet over radio, current cellular radio standards, and recent changes in spectrum management, including the availability of unlicensed bands and new mm band frequencies between 70 and 90 GHz. The book is illustrated with b&w diagrams, and includes appendices of formulae and acronyms. Annotation c2009 Book News, Inc., Portland, OR (booknews.com)
