6.4 Configuring Roaming
A wireless station is a device with an IEEE 802.11b or an IEEE 802.11g compliant wireless
inteface. 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.
In a network environment with multiple access points, wireless stations are able to switch from
one access point to another as they move between the coverage areas. This is roaming. As the
wireless station moves from place to place, it is responsible for choosing the most appropriate
access point depending on the signal strength, network utilization or other factors.
