Page 15: Wlan Service Overview
WLAN Service Overview Wireless Local Area Networks (WLAN) have become very popular because they are very easy to setup and use, and users need not care about the complex wiring connections and relocation problems. A WLAN is not completely wireless because the servers in the backbone are fixed and clients are mobile. - Page 16 Wireless Medium A medium that is used for transmitting frames between clients. Radio Frequency is used as the wireless medium in the WLAN system. Distribution System The distribution system is used to forward frames to their destination. It is the backbone to transmit frames between access points. Split MAC In Split MAC mode, the services to be managed are distributed between AP and AC.
- Page 17 the AP, which relays this frame to the AC. The AC sends an authentication response to the AP, which conveys this response to the client. See WLAN Security Configuration for more information on shared key authentication. 11) De-Authentication The AC or Fat AP sends a de-authentication frame to remove client(s) from the wireless system.

Page 18: 802.11 Overview
14) Re-association When a client is roaming from one AP area/BSS area to another, it sends a re-association request to the new AP/BSS area. The AP relays this re-association request to the AC. The AC then informs the previous AP to delete the client’s information from its database, informs the new AP to add the client’s information in its database and conveys successful reassociation information to the client. - Page 19 Single BSS The coverage of an AP is called a Basic Service Set (BSS). Each BSS is identified by a BSSID. The most basic WLAN network can be established with only one BSS. All wireless clients associate with same BSS. If those clients have the same authorization, they can communicate with each other.
- Page 20 Figure 6-2 Multiple ESS network Generally a Fat AP can provide more than one logical ESS at the same time. The Fat AP can broadcast the current information of ESS by Beacon or Probe response frames. Clients can select an ESS it is interested to join.
