ABSTRACT
The article presents information on large-scale wireless LAN (WLAN). Most WLAN vendors are using technology that was designed with the assumption that a wireless LAN consisted of one access point (AP) and a small handful of users. The AP broadcasts a signal to announce its presence, and any client in the area can connect to the AP, assuming the client meets security requirements. The AP operates independently and, therefore, is not aware of any nearby APs, and does nothing to manage its output to facilitate coexistence with other APs. With APs that collaborate to provide coverage, the WLAN becomes a single infrastructure through which any client can roam without having to re-authenticate as it moves from one AP coverage area to another. Cellular telephone networks have successfully supported massive increases in user density and demanding new applications for two decades without any major hiccups. Large organizations deploying pervasive WLANs require the same robustness and performance.
