Roaming
In an infrastructure network, wireless clients are able to switch from one AP to another as they move
between the coverage areas. During this period, the wireless client maintains uninterrupted connection to
the network. This is roaming. As the wireless client 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 2
in order to stay
connected to the network.
