Wireless local area networks (WLANs) have traditionally been used to transport only data, but are now being used to carry voice traffic as well as provided new combined voice and data services. Voice over WLANs also offers more flexibility than wired networks (changes to a WLAN dont require changes to installed wiring) and greater capacity than wired networks. This book provides a solid overview of voice over WLANs/​VoIP (voice over internet protocol) technology, including voice coding, packet loss, delay and jitter, and echo control. It shows how to combine both WLAN and VoIP technology to create effective voice over WLAN systems. * 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.
"The transition from traditional circuit-switching telephony systems to IP-based telephony is underway, and nowhere is this more evident than in the convergence of telephony and wireless networks. Despite the many advantages of Voice Over WLAN systems, design and implementation of such systems is a challenge for any communications engineering professional, especially when it comes to interfacing wireless networks to the landline telephone network." "This book provides the necessary information to successfully Implement Voice Over WLAN systems. In this book, you'll find concise explications of the key points of Voice Over WLAN technology, including the essential concepts of wireless networks and telephony systems, the fundamentals of packet-switched networks, important issues relating to quality of service, and how to configure WLANs for voice traffic."--BOOK JACKET
