Figure 1-2 Infrastructure Configuration

The infrastructure configuration supports roaming capability for mobile workers. More than one BSS can be jointly

configured as an Extended Service Set (ESS). On account of a continuous connection to the network, users within

this ESS can roam freely. All WLAN USB dongles and APs within one ESS must be configured with the same ESS

ID.

Before setting up an ESS for roaming, it would be helpful to achieve good performance by choosing a feasible radio

channel and right places for APs.
