This complete guide to planning, deploying and managing Wi-Fi telephone networks explains the economics of Wi-Fi, so network engineers can show the return-on-investment from implementing Wi-Fi. The book also examines key Wi-Fi technology issues.

Secure Roaming in 802.11 Networks offers a comprehensive treatise on Wi-Fi 802.11 roaming by comparing/contrasting it to cellular roaming theory and techniques. The book explores the fundamental concepts, basic theory, and key principles of 802.11 networks with roaming capabilities. It helps ensure secure and constant connectivity of laptops, PDAs and other emerging mobile devices. Today, we increasingly expect to find public Wide Local Area Network (WLAN) 802.11 access in our airports, public spaces, and hotels, and we want to maintain our connections when we’re mobile and using 802.11 WLANs. However, 802.11 was not originally designed with roaming capabilities and can’t, in its "pure" form, support seamless roaming between different hotspots and other 802.11 access points. This book details the theory behind various 802.11 extensions to permit roaming and describes how these extensions can be successfully implemented in 802.11 WLANs. It reviews coverage of user authentication in 802.11, as well as roaming between 802.11 and other wireless technologies. It also discusses wireless technologies and application programming interfaces. This book will appeal to RF/wireless engineers and designers, computer/data network engineers, and graduate students. * Offers a comprehensive treatise on Wi-Fi 802.11 roaming by comparing/contrasting it to cellular roaming theory and techniques * Emerges as a "one stop" resource for design engineers charged with fulfilling the market need for seamless 802.11 device roaming capabilities * Builds upon the knowledge base of a professional audience without delving into long discussions of theory long since mastered

Now in its seventh edition, The Art of Voice Acting covers all aspects of the craft and business of performing voiceover. Starting with the basics of voice acting, every aspect of the craft and business of performing voiceover is explained in detail, including how to get started, performing techniques, setting up a personal recording space, voiceover demos, the basics of running a voiceover business, unions and much, much more. This edition is completely updated with all new scripts, discussions of the latest trends in voiceover and contributions from some of the voiceover industry’s top performers, casting directors and agents. The book provides a wealth of practical information that can be put to work immediately, as well as hundreds of references to websites and other useful resources. Anyone interested in acting, storytelling, any area of voiceover or simply improving verbal communication skills will benefit from this book. Although The Art of Voice Acting is a great learning tool for the beginner, it will also serve the experienced performer well as a reminder of performing and business tools that are essential in today’s world of acting and voiceover. Additional content, including scripts, audio files, and unpublished content can be found at www.AOVA.VoiceActing.com.

This book constitutes the refereed proceedings of the 10th International Teletraffic Congress, ITC 2007, held in Ottawa, Canada, June 2007. Coverage includes IPTV planning and modeling, network performance, traffic engineering, end-to-end delay in converged networks, queuing models, impact of convergence and divergence forces on network performance, traffic management in wireless networks, and network design for capacity and performance.

This book, suitable for IS/IT courses and self study, presents a comprehensive coverage of the technical as well as business/management aspects of mobile computing and wireless communications. Instead of one narrow topic, this classroom tested book covers the major building blocks (mobile applications, mobile computing platforms, wireless networks, architectures, security, and management) of mobile computing and wireless communications. Numerous real-life case studies and examples highlight the key points. The book starts with a discussion of m-business and m-government initiatives and examines mobile computing applications such as mobile messaging, m-commerce, M-CRM, M-portals, M-SCM, mobile agents, and sensor applications. The role of wireless Internet and Mobile IP is explained and the mobile computing platforms are analyzed with a discussion of wireless middleware, wireless gateways, mobile application servers, WAP, i-mode, J2ME, BREW, Mobile Internet Toolkit, and Mobile Web Services. The wireless networks are discussed at length with a review of wireless communication principles, wireless LANs with emphasis on 802.11 LANs, Bluetooth, wireless sensor networks, UWB (Ultra Wideband), cellular networks ranging from 1G to 5G, wireless local loops, FSO (Free Space Optics), satellites communications, and deep space networks. The book concludes with a review of the architectural, security, and management/support issues and their role in building, deploying and managing wireless systems in modern settings.
