Chapter 2
Wireless LAN Networking
This chapter provides background information on general wireless LAN networking technology
and terminology.
2.1 Overview
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 radio frequency used by a wireless device is called a channel.
2.1.3 Transmission Rate (Transfer Rate)
The ZyXEL AG-200 provides various transmission (data) rate options for you to select. Options include
Fully Auto, 1 Mbps, 2 Mbps, 5.5 Mbps, 11 Mbps, 6 Mbps, 9 Mbps, 12 Mbps, 18 Mbps, 22 Mbps, 24
Mbps, 36 Mbps, 48 Mbps, 54 Mbps and 108 Mbps. In most networking scenarios, the factory default
Fully Auto setting proves the most efficient. This setting allows your ZyXEL AG-200 to operate at the
maximum transmission (data) rate. When the communication quality drops below a certain level, the
ZyXEL AG-200 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 ZyXEL
AG-200 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 ZyXEL AG-200
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.
