ZyAIR Wireless LAN Utility
For ZyAIR B122 and ZyAIR B-320, you may select the proprietary transmission
rates of 16.5M bit/sec or 27.5M bit/sec if you are connecting to another ZyAIR B-

320, ZyAIR B-122 client or ZyAIR B-500 AP and vice versa.

2.1.4 Wireless Network Application

Wireless LAN works in either of the two modes: ad-hoc and infrastructure.
To connect to a wired network within a coverage area using Access Points (APs), set the ZyAIR operation
mode to Infrastructure(BSS). An AP acts as a bridge between the wireless stations and the wired network.
In case you do not wish to connect to a wired network, but prefer to set up a small independent wireless
workgroup without an AP, use the Ad-hoc (IBSS) (Independent Basic Service Set) mode.
Ad-Hoc (IBSS)
Ad-hoc mode does not require an AP or a wired network. Two or more wireless clients communicate
directly to each other. An ad-hoc network may sometimes be referred to as an Independent Basic Service
Set (IBSS).

Figure 2-1 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.

At the time of writing, the proprietary transmission rates are only available for ZyAIR B-122, ZyAIR B-
320 and ZyAIR B-500.
