a truly mobile Internet dates back to the mid-1990s, it is only now that a signifi-

notonlyinEuropeandJapan,butalsothroughoutNorthandLatinAmericas.This

ThefocusofthebookisonthetwolowerlayersoftheISO/OSIlayeredmodel,
that is, the physical and data link layers, including the link and media access con-
trol sublayers. These two layers are of specific importance in wireless systems, as
opposed tomany ofitswiredcounterparts. This isfundamentally due tospectrum
shortage, the broadcast nature of interference, and time variability of the wireless
channel. As a consequence, much of the improvements in coverage, capacity, and

IntendedAudienceandUsage
This book is intended for researchers in the field of wireless communications,
more specifically to the ones involved with the design and optimization of current
and emerging wireless access technologies for mobile communications. Graduate
students working in subjects such as radio resource management, OFDM, and
MIMO, as well as in third-generation systems and beyond, will benefit from the
