1 Many information systems are represented as two-dimensional networks of links and nodes. Because these networks tend to be large and quite complex, people often prefer to view part or all of the network at varying levels of detail. Hierarchical clustering provides a framework for viewing the network at different levels of detail by superimposing a… (More)
In this paper, we focus on high speed wireless LAN architecture. The goal is to give a general introduction to the next generation of wireless LAN standard. Described here are Physical Layer and Media Access Layer of both IEEE 802.11 and HIPERLAN standards.
