6.4 Configuring Roaming
A wireless station is a device with an IEEE 802.11b compliant wireless adapter. An access point (AP) acts as
a bridge between the wireless and wired networks. An AP creates its own wireless coverage area. A wireless
station can associate with a particular access point only if it is within the access point’s coverage area.
