2.1.5 Roaming
In an infrastructure network, wireless stations are able to switch from one BSS to another as they move
between the coverage areas. During this period, the wireless stations maintain uninterrupted connection to
the network. This is roaming. As the wireless station moves from place to place, it is responsible for
choosing the most appropriate AP depending on the signal strength, network utilization or other factors.
