'As the field of wireless communications continues to spread and evolve, students, engineers, practitioners, and researchers face a daunting multitude of books and an enormous literature that often misleads and confuses. Andrea Goldsmith's book offers an up-to-date, comprehensive, reader-friendly, and valuable alternative. It is a veritable tour-de-force that sweeps the entire field with clarity, completeness, and sufficient detail that strikes a masterful balance between breadth and depth. I recommend it highly to anyone interested in a serious foray into the science and technology of wireless communications.'
