(More customer reviews)Are you an experienced WLAN engineer and administrator? If you are, then this book is for you. Authors Praphul Chandra and David Lide, have done an outstanding job of writing a book about using wireless local area networks to carry human speech and voice.
Chandra and Lide, begin by looking at how voice has traditionally been carried over networks. In addition, the authors briefly introduce the packet-based data networks: the Internet. They also take a look at how VoIP works. Then, they discuss the challenges of Voice-over-802.11b networks. The authors then focus on the solutions of the challenges of system capacity and QoS in some detail. Next, they look at WEP, why it fails and what is being done to close these loopholes. Then, they look at some of the issues with roaming in Wi-Fi networks. The authors continue by discussing why a good power-management scheme requires a systems solution to be successful. Finally, they take a look at voice over Wi-Fi in conjunction with other wireless technologies, including proposed 802.11extendsions, cellular, WiMax, Bluetooth, and conventional cordless phone systems.
This most excellent book is a very thorough guide to voice over WLANs. Perhaps more importantly, this book will give you the theoretical backgrounds and practical details necessary to design, implement, and maintain the new generation of voice-over-WLAN telephony systems!
