WLAN technology is progressing rapidly, but the most widely accepted is the IEEE 802.11 WLAN standard. This text is unique and very practical to introduce the principles of WLAN based on IEEE 802.11 standards, shows how to configure the equipment to implement various network solutions. Readers will gain an understanding of the implications of wireless network security and learn how the vulnerability can be reduced. In addition, this book discusses the underlying 802.11 protocol and explains how to build a mathematical model to analyze the performance of the WLAN environment. Topics and Features: presents a practical approach supported by extensive use of examples and detailed instructions; discuss the various wireless networking solutions in a number of platforms of different vendors, including Cisco Aironet, Alactel-Lucent Omniaccess and Meru Networks, provides a variety of mathematical models to analyze the performance of IEEE 802.11 standard , and show how to build this model using Maple; discusses wireless security issues and explains how to create a wireless network security company; investigate the media access control sub-layer, and a model for the MAC layer performance analysis; review sub-802.11 physical layer, describes the technique modulation and examine how the devices adapt to a changing RF environment. A very useful text / reference for industry professionals, undergraduate and postgraduate students will also find this book an ideal companion for university courses in wireless networking.
