ABSTRACT:
Wireless local area network (WLAN) management. A novel approach is provided to associate various wireless stations (STAs) to the WLAN via appropriately selected Access Point (APs). In one implementation, a first AP services only those STAs that have functionality of a first user class (e.g., 802.11b functionality in one instance. In addition, a second AP services only those STAs that have functionality of a second user class (e.g., 802.11g functionality). The WLAN management ensures that STAs having similar characteristics (or similar functionality) are grouped together and associated with an AP that corresponds to those characteristics. For example, 802.11b STAs associate with the WLAN via an 802.11b AP. Analogously, 802.11g STAs associate with the WLAN via an 802.11g AP. When an 802.11g STA is unable to associate with the WLAN via an 802.11g AP, the STA may shift down its functionality set to 802.11b to successfully associate with the WLAN.
