2-2 Using the ZyAIR Utility

 To set up an ad-hoc network, configure all wireless clients

in ad-hoc network type and use the same SSID and channel.

Infrastructure

When a number of wireless clients are connected using a single AP, you have a Basic Service Set

(BSS).

Figure 2-2 BSS Example

A series of overlapping BSS and a network medium, such as an Ethernet forms an Extended

Service Set (ESS) or infrastructure network. All communication is done through the AP, which

relays data packets to other wireless clients or devices connected to the wired network. Wireless

clients can then access resource, such as the printer, on the wired network.

Figure 2-3 Infrastructure Network Example

2.1.5 Roaming

Roaming is where in an infrastructure network, wireless clients are able to switch from one BSS

to another as they move between coverage areas. During this period, the wireless client maintains

uninterrupted connection to the network. As the wireless client moves from place to place, it

scans for 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.
