Wi-FiTM: Architecture and Functions
In just the past few years, WLANs have gained a tremendous place in the local area network (LAN) market. Today, WLANs based on the IEEE 802.11 standard constitute a practical and interesting solution of network connection offering mobility, flexibility, low cost of deployment and use. The purpose of this chapter is to describe in a detailed way the concepts, principles of operation and rationales behind some of the features and/or components of the standard which was originally started in 1997. We chose a clear and concise style of writing to facilitate the understanding of the inherent concepts in this technology, which sometimes require knowledge from several disciplines. Different aspects are covered throughout the chapter.
