Using the ZyAIR Utility
This chapter shows you how to configure the ZyAIR using the ZyAIR Utility.
2.1 About Wireless LAN Network
This section describes the wireless LAN network terms and applications.
2.1.1 SSID
The SSID (Service Set Identity) is a unique name shared among all wireless devices in a wireless network.
Wireless devices must have the same SSID to communicate with each other.
2.1.2 Channel
A range of radio frequencies used by IEEE 802.11b wireless devices is called a channel.
2.1.3 Transmission Rate
Your ZyAIR automatically adjusts the transmission rate to operate at the maximum transmission
(data) rate. When the communication quality drops below a certain level, the ZyAIR
automatically switches to a lower transmission (data) rate. Transmission at lower data speeds is
usually more reliable. However, when the communication quality improves again, the ZyAIR
gradually increases the transmission (data) rate again until it reaches the highest available
transmission rate.
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).
