This book paves the path toward fourth generation (4G) mobile communication
by introducing mobility in heterogeneous IP networks with both third
generation (3G) and wireless local area networks (WLANs), which is seen as
one of the central issues in the becoming 4G of telecommunications networks
and systems. This book presents a thorough overview of 3G networks and
standards and discusses interworking and handover mechanisms between
WLANs and the Universal Mobile Telecommunication System (UMTS).
This book is a new, forward-looking resource that explores the present
and future trends of WLANs and wireless personal area networks (WPANs).
This book also provides the discovery path that these infrastructures are following
from a perspective of synergies with 3G systems and how they will
pave the way for future 4G systems. It is a good resource for learning what
performance can be expected from WLANs and WPANs when they support
the Transmission Control Protocol (TCP)/IP stack. Several critical issues are
examined in depth, including IP routing and mobility, the ad hoc concept,
IEEE 802.11 and the high performance WLAN (HIPERLAN/2) standards,
physical (PHY) and medium access control (MAC) layers for the main WLAN
specifications, the TCP-User Datagram Protocol (UDP)/IP protocol stack,
and the performance of the TCP-UDP/IP stack over the IEEE 802.11b platform.
An entire chapter is devoted to the WPAN domain, where a detailed
treatment of Bluetooth and a second generation (2G) outlook are provided.
