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 station B moves to position X, the ZyXEL

AG-200 in wireless station B automatically switches the channel to the one used by access point 2 in order

to stay connected to the network.
