Download or read book Beyond VoIP Protocols written by Olivier Hersent and published by John Wiley & Sons. This book was released on 2005-03-04 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1999-2000, VoIP (Voice-over-IP) telephony was one of the most successful buzzwords of the telecom bubble era. However, in 2001-2003, VoIP faced a very tough reality check. Now, manufacturers and service providers are drawing on what they have learnt from past experience in order to prepare to participate in the next major challenge faced by the telecommunications industry. This book offers a comprehensive overview of the issues to solve in order to deploy global revenue-generating effective "multimedia" services. Drawing on extensive research and practical deployment experience in VoIP, the authors provide essential advice for those seeking to design and implement a post-bubble VoIP network. Beyond VoIP Protocols: Understanding Voice Technology and Networking Techniques for IP Telephony Introduces the basics of speech coding and voice quality Demonstrates how quality of service may be built into the network and deals with dimensioning aspects, e.g. multipoint communications and how to model call seizures. Explores the potential of multicast to turn an IP backbone into an optimized broadcast medium Includes amply illustrated, state-of-the-art practical advice for formulating a complete deployment strategy A companion volume to "IP Telephony: Deploying VoIP Protocols", this book takes the reader a stage deeper into how to prepare the network and exploit VoIP technology to its full potential.
Download or read book Fixed Mobile Convergence and Beyond written by Richard Watson and published by Newnes. This book was released on 2008-10-09 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mobile communications users are demanding increased reliability, functionality, and accessibility; they want "always on" access to voice, e-mail, text, and multimedia services as they roam from home to auto to office to outdoor/indoor locations. In addition, there is an increasing deamnd to replace separate landline/mobile telephones with a single handset that can be used wherever its owner might be. Answering those customer needs, fixed/mobile convergence (FMC) marries the mobility provided by cellular networks with the extended connectivity provided by 802.11-based WiFi services and integrates them with landline networks using a single handset.This book provides the theoretical and practical background necessary to successfully plan, develop, and deploy effective FMC networks. This book discusses the various 802.11 and VoIP protocols used in FMC networks, open and proprietary communications protocols, integration of FMC networks to wired telephone networks, mobilizing applications such as text messaging and video, security issues, mobile handset requirements for FMC networks, and the administration/management of FMC networks. Special attention is given to selecting appropriate components for FMC, and numerous case histories and examples from the author's experience are provided.This book is an essential tutorial and reference for any RF/wireless, communications, and networking professional who will work with the next generation of wireless networks. Describes how to develop, deploy, and manage networks that seamlessly combine landline, cellular, and WiFi networks into one converged communications network Thorough coverage of various 802.11 and voice over internet protocol (VoIP) standards and how they impact integration with cellular networks Discusses security considerations and how to successfully manage converged networks Includes numerous case histories and examples from the author's experience---this is not a purely theoretical treatment of the subject!
