Wi-Fi telephony is the latest, most cost effective, and clearest way of carrying voice data wirelessly. The great news is that it can be integrated seamlessly into the same infrastructures as currently used for computer and telephone data.The digital quality is far above current cellular technologies. This book will be among the first to discuss Session Initiation Protocol (SIP), Quality of Service (QoS), and interoperability in connection with Wi-Fi telephony. Security challenges are also presented and solved along these malleable wireless boundaries. In short, this book provides all the information necessary for effective, reliable, crystal clear Wi-Fi telephony service and implementation. *Using current telephone and computer infrastructure this technology can be implemented at low cost *The importance of Quality of Service (QoS) and security of Wi-Fi telephony is considered *Enhances the clarity of a call beyond a basic cellular phone using digital data transfer

Fed up with the high tolls charged by your ordinary telephone service? If you're itching to cut the copper cord with your costly, traditional phone service, you need Talk is Cheap, the new, easy-to-understand guide to understanding and using Voice over Internet Protocol (VoIP) and other Internet telephone options. Technologies such as VoIP are gaining a great deal of attention these days as more people switch from standard telephone service to phone service via the Internet. But while the cost savings are outstanding, there are some issues with Internet telephony that you should know about. Are the connections reliable? Is the quality comparable? Will it include 911 services? James Gaskin's Talk is Cheap addresses these issues and many more by explaining how to make the switch and what the tradeoffs will be if you opt for Internet telephony over traditional phone services. Talk is Cheap focuses on the increasingly popular services from Vonage, which uses VoIP, and Skype--a free service that operates as a peer-to-peer (P2P) network with the ability to turn any PC, Mac, or Pocket PC into a telephone. The book explains your options; explores the background behind, the workings of, and differences between VoIP and P2P networks; and discusses the advantages and drawbacks of both technologies (including service offerings, quality, capabilities, completion rates, and more). Talk is Cheap then goes into detail on what you can expect in Internet service from traditional phone companies such as Verizon and AT&T. In addition, you will learn more advanced techniques, including how to turn your Palm or Pocket PC into an Internet phone and how to work with Wi-Fi phones and videophones. A straightforward, quick introduction to the ins and outs of using Internet telephone services, this book provides everything you need to make informed telephone decisions--whether you're thinking about the switch from traditional phone service or have already made it and want to get the most out of your new Internet telephone.

"...excellent for use as a text in information assurance orcyber-security courses...I strongly advocate thatprofessors...examine this book with the intention of using it intheir programs." (Computing Reviews.com, March 22, 2007) "The book is written as a student textbook, but it should beequally valuable for current practitioners...this book is a veryworthwhile investment." (Homeland Security Watch, August 17,2006) While the emphasis is on the development of policies that lead tosuccessful prevention of terrorist attacks on the nation’sinfrastructure, this book is the first scientific study of criticalinfrastructures and their protection. The book models thenation’s most valuable physical assets and infrastructuresectors as networks of nodes and links. It then analyzes thenetwork to identify vulnerabilities and risks in the sectorcombining network science, complexity theory, modeling andsimulation, and risk analysis. The most critical components become the focus of deeper analysisand protection. This approach reduces the complex problem ofprotecting water supplies, energy pipelines, telecommunicationstations, Internet and Web networks, and power grids to a muchsimpler problem of protecting a few critical nodes. The new editionincorporates a broader selection of ideas and sectors and moves themathematical topics into several appendices.
