Book Description :

For networking and RF/wireless engineers, and graduate students who want a solid overview of voice over WLANs/VoIP technology (wireless local area networks / voice over internet protocol), this book covers voice coding, packet loss, delay and 'jitter', and 'echo' control, and shows how to combine both WLAN and VoIP technology to create effective voice over WLAN systems. Finneran also describes how to integrate voice over WLAN systems with cellular networks. This is not just another WLAN-only book nor a VoIP-only book; instead, it integrates both topics into a coherent whole. * Gives complete details on integrating voice and data services on WLANs, including wide area networks * Explores quality of service (QoS) and security issues * Step-by-step descriptions of how to plan and implement voice over WLAN networks

Book Description :

Deploying Voice over Wireless LANs The definitive guide to planning, architecting, deploying, supporting, and creating Voice over Wireless LAN solutions Recent advances make it possible to deliver high-quality voice and video communications over a wireless LAN (WLAN), replacing costly wired telephone and video surveillance systems and dramatically reducing support costs. However, today's new voice over WLAN (VoWLAN) technologies require fundamentally different skills and techniques from those used in traditional voice and video systems. Now, there's a complete guide to every facet of VoWLAN deployment: planning, design, installation, security, maintenance, and troubleshooting. Authored by wireless industry expert and leader Jim Geier, Deploying Voice over Wireless LANs draws on Geier's extensive experience with real-world VoWLAN deployments. Geier brings together state-of-the-art insights into VoWLAN technologies, standards, products, services, implementation strategies, and much more. Geier begins by introducing key components of today's VoWLAN systems, including phones, client software, and voice encoders/decoders, as well as VoWLAN signaling essentials such as analog-to-digital (A/D) conversion and compression. Using examples drawn from actual enterprise settings, you'll learn exactly how VoWLAN products integrate with existing IP infrastructure. Next, he introduces crucial emerging 802.11 standards for effective VoWLAN deployment, including 802.11e quality of service (QoS) standards, 802.11r to minimize packet loss between access points, and 802.11k network discovery. He carefully reviews the security implications of VoWLAN voice, systematically covering both risks and countermeasures. Finally, Geier walks through implementation from start to finish, thoroughly covering analysis, design, installation, configuration, testing, and support. Whatever your role in planning, delivering, managing, or creating wireless voice and video solutions, Deploying Voice over Wireless LANs is your most comprehensive, authoritative resource. Jim Geier founded Wireless-Nets, Ltd., and serves as its principal consultant. His 25 years of experience includes the analysis, design, software development, installation, and support of numerous wireless networking systems. He has been active within the Wi-Fi Alliance and the IEEE 802.11 Working Group and helped develop international standards for WLANs. His books include Wireless Networks First Step (Cisco Press), Wir...

Book Description :

IPv6 (Internet Protocol version 6) is the future of Internet telephony. And this book is your guide to that future. IPv6 is the replacement for the currently used IPv4 (Internet Protocol version 4). IPv6 will offer increased IP addresses (full 128-bit addresses, compared to the 32-bit addresses of IPv4), enhanced security, and greater robustness. It will also be fully “backwards compatible with existing IPv4 systems. These capabilities will finally make Internet telephony a viable competitor to conventional switched telephone networks. In this book, Dan Minoli clearly explains IPv6 and how telephone networks can be built on its foundations. This is not just another IPv6 book; instead, it focuses on those aspects of IPv6 relevant to Internet telephony systems and voice networks. Minoli uses a compare/contrast approach, exploring where IPv6 is similar to IPv4 and where it differs, to let you quickly grasp the essence of IPv6 and the similarities (and differences) between current IPv4-based systems and IPv6-based systems. If you will be designing, implementing, or maintaining the next generation of Internet telephony systems, then you need the information in this book! *Explains the essential concepts of IPv6 and how they relate to Internet telephony *Describes how Internet telephony systems using IPv6 are different from, and better than, Internet telephony systems based on the older IPv4 standard *Discusses how to transition existing IPv4 Internet telephony systems and conventional switched systems to IPv6-based systems *Extensive treatment of security issues, including IP layer encryption and authentication methods *Explains connection techniques, including “plug and play approaches, for equipment used in IPv6 systems * The first title describing how the next generation Internet protocol—IPv6—can be used for Internet telephony * Explains IPv6 as it applies to Internet telephony (VoIP) * Shows how IPv6 gives better security, QoS, and signal integrity in Internet telephony
