Roaming
In an infrastructure network, wireless stations are able to switch from one AP to another as they move
between the coverage areas. During this period, the wireless stations maintain uninterrupted connections 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 simple roaming example. When Wireless Station B moves to position X, the
ZyAIR in Wireless Station B automatically switches the channel to the one used by AP 2 in order to stay
connected to the network.
