Figure 3-6 Infrastructure Network Example 
3.6 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.
