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.
