Architecture is designed to support a network where mobile station is responsible for the decision making. Advantages are ² very tolerant of faults in all of the WLAN equipment. ² eliminates any possible bottlenecks a centralized architecture would introduce. Architecture has power-saving modes of operation built into the protocol to prolong the battery life of mobile equipment without losing network connectivity. Components Station the component that connects to the wireless medium. Supported services are authentication, deauthentication, privacy, and delivery of the data | Tutorial Mustafa Ergen Mustafa Ergen June 2002 ergen@eecs.berkeley.edu Department of Electrical Engineering and Computer Science University of California Berkeley 2 Abstract This document describes IEEE 802.11 Wireless Local Area Network WLAN Standard.
