This book is about wireless local area networks (WLANs) based upon the
IEEE 802.11 standards. It has three primary objectives: - To introduce
the principles of 802.11 wireless networks and show how to con- ure
equipment in order to implement various network solutions. - To provide
an understandingof the security implicationsof wireless networks and
demonstrate how vulnerabilities can be mitigated. - To introduce the
underlying 802.11 protocols and build mathematical models in order to
analyse performance in a WLAN environment. The book is aimed at industry
professionals as well as undergraduate and gra- ate level students. It
is intended as a companion for a university course on wireless
networking. A practical approach is adopted in this book; examples are
provided throughout, supported by detailed instructions. We cover a
number of wireless vendors; namely, Cisco's Aironet, Alactel-Lucent's
Omniaccess and Meru Networks. While separate vendors, all three systems
have a Cisco IOS-like command-line interface. The GNU/Linux operating
system is used extensively throughout this book.
