In the preparation of this book, our objective was to provide an advanced understanding of emerging
telecommunications systems, their signifcance, and the anticipated role these systems will play in the
future. In addition to our new discussions of radio frequency identifcation (RFID) and wireless sensor
networks, this book addresses network management and administration, as well as network organiza-
tion and governance, topics that were not as clearly defned during the development of the frst edition.
With the help of our t
alented contributors, we believe we have accomplished this. By addressing voice,
Internet, network and trafc management, along with future trends, we feel our readers will be knowl-
edgeable about current and future telecommunications systems.
