Internet and wireless technologies are converging towards an exciting future that we've only begun to realize. For professionals who have a background in the Internet or in mobile telephony - but not in both - this integrated "how it works" guide offers a practical understanding of wireless Internet communications, the technology components involved, and how they fit and work together. It provides a unified picture of important protocols for multimedia transport and session control, and explains what's being done to tackle tough challenges in QoS control, mobility management, and security in the wireless environment. With enhancements to the next generation of the Internet protocol expected to provide greater support for wireless IP network...

Written by experts in academia and industry, this manual takes a comprehensive look at the convergence of wireless and Internet technologies that are giving rise to the mobile wireless Internet. This resource offers practitioners an overview of all the elements required to understand and develop future IP (Internet Protocol) based wireless multimedia communications and services....

A guide to wide-area data network performance engineering. It discusses the skills needed to design a router network carrying a variety of traffic, including Internet and intranet, over frame relay devices. It covers routers, protocols including TCP/IP, SNA and Novell, protocol behaviour over a WAN, applications, performance engineering, network management and maintenance, and more. The text offers itself as a resource to keep on hand while operating, maintaining, upgrading, or migrating existing networks. It helps the reader to make difficult decisions involving hardware, software, frame relay and private lines, ATM, and application benchmarking to test new applications on the WAN....

An exploration of the present and future trends of WLANs and WPANs. It examines the 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. The authors present an overview of 3G networks and standards, and discuss intraworking and handover mechanisms between WLANs and WPANs when they support the TCP/IP stack. Several critical issues are explored in depth, including IP routing and mobility, the ad hoc concept, IEEE 802.11 and the HIPERLAN/2 standards, PHY and MAC layers for the main WLAN specifications, the TCP-UDP/IP protocol stack, and 802.11b over TCP/IP....

Wi-Fi can further enhance your organization's productivity and savings by increasing portability and eliminating charges for PBX maintenance and for wire-line and cellular phone service. However, concerns about the QoS of Wi-Fi and VoIP prevent many organizations from realizing the full savings and productivity improvements that Wi-Fi can deliver. This guide to deploying Wi-Fi telephony helps you overcome these concerns by showing in detail how to engineer each component of Wi-Fi for reliable, high- quality voice transmission. This informative reference reveals how Voice over Wi-Fi is a scalable, secure networking solution that supports today's demanding application needs. The book explains the ins and outs of the 802.11 standard, Softswitch architec...
