2-2 Roaming
Infrastructure mode also supports roaming capabilities for mobile users. More than
one BSS can be configured as an Extended Service Set (ESS). The continuous network
allows users to roam freely within ESS. All wireless PCMCIA cards and Access Point
within one ESS must be configured with the same ESSID in order to utilize roaming
function. Properly Access Point positioning with a clear radio signal can greatly
enhance wireless performance.
