2.1.4.3 Access Point Mode

The following figure depicts a network example in which you set the ZyAIR in access point
mode.

Figure 6 ZyAIR as an Access Point Example

In the example, the ZyAIR is installed on computer A and set to operate in access point mode.
Computer A shares Internet connection to the wireless LAN, so wireless stations B and C can
access the Internet.

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 ZyAIR in wireless station B automatically switches the channel to the one used by
access point 2 in order to stay connected to the network.
