Book Synopsis Cellular Convergence and the Death of Privacy by : Professor Stephen B. Wicker
Download or read book Cellular Convergence and the Death of Privacy written by Professor Stephen B. Wicker and published by Oxford University Press. This book was released on 2013-08-21 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cellular technology has always been a surveillance technology, but "cellular convergence" - the growing trend for all forms of communication to consolidate onto the cellular handset - has dramatically increased the impact of that surveillance. In Cellular Convergence and the Death of Privacy, Stephen Wicker explores this unprecedented threat to privacy from three distinct but overlapping perspectives: the technical, the legal, and the social. Professor Wicker first describes cellular technology and cellular surveillance using language accessible to non-specialists. He then examines current legislation and Supreme Court jurisprudence that form the framework for discussions about rights in the context of cellular surveillance. Lastly, he addresses the social impact of surveillance on individual users. The story he tells is one of a technology that is changing the face of politics and economics, but in ways that remain highly uncertain.

Book excerpt: 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.
