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.
The following figure depicts a roaming example. When Wireless Client B moves to position X, the ZyAIR
in Wireless Client B automatically switches the channel to the one used by access point AP 2 in order to
stay connected to the network.
