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 each wireless LAN parameter.  
2.1.1 Channel 
A radio frequency used by a wireless device is called a channel. 
2.1.2   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. 
2.1.3  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. 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 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).
