The main function of an AP is to form a bridge between wireless and wired LANs. When an AP is present within a BSS, STAs do not communicate on a peer-to-peer basis.ee Brief Tutorial on IEEE 802.11 Wireless LANs TM Application Note February 1999 AN9829 Authors: Jim Zyren and Al Petrick Introduction [ /Title (AN98 /Subject (Brief Tutorial on IEEE 802.11 Wireless LANs) /Autho Final approval of the IEEE 802.11 standard for wireless local area networking (WLAN) last year and rapid progress made toward higher data rates have positioned this technology to fulfill the promise of truly mobile computing. While wired LANs have been a mainstream technology for at least fifteen years, WLANs are uncharted territory for most networking professionals. There are some important differences worth explaining. When considering wireless networking, some obvious questions come to mind: How can WLANs be integrated with wired infrastructure? What is the underlying radio technology How is multiple access handled? What about network security? A more common and far more and flexible configuration is that of a BSS which contains an Access Point (AP). Instead, all communications between STAs or between an STA and a wired network client go through the AP.
