This newly revised edition of an Artech House bestseller provides you with an up-to-date introduction to third generation (3G) mobile communication system principles, concepts, and applications. The book clearly presents the basics of UMTS systems in one comprehensive volume, without bogging you down with advanced mathematics. The second edition includes an even more thorough treatment of potential 3G applications and descriptions of new, emerging technologies such as 3G System Release number 5, HSDPA, and Multimedia Broadcast/Multicast Service (MBMS). It also features discussions on both 3GPP and 3GPP2 evolution paths, the specification process, and future 3G upgrades.
