“Secure Roaming in 802.11 Networks” by Goransson Greenlaw (published by Newnes, an imprint of Elsevier) explores the fundamental concepts, basic theory, and key principles of 802.11 networks with roaming capabilities. With increasing public Wide Local Area Network (WLAN) 802.11 access in airports, public spaces, and hotels, maintaining WLAN connections is a major issue.

However, 802.11 was not originally designed with roaming capabilities and does not support seamless roaming between different hotspots and other 802.11 access points in its original form. This book details the theory behind various 802.11 extensions to permit roaming and describes how these extensions can be successfully implemented in 802.11 WLANs. Coverage of User Authentication in 802.11 is reviewed as is roaming between 802.11 and other wireless technologies. Wireless technologies and application programming interfaces are also covered.
