Wireless LAN Network

This chapter provides background information on wireless LAN network.

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 G-162 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 125 Mbps. In most networking scenarios, the factory default Fully Auto
setting proves the most efficient. This setting allows your G-162 to operate at the maximum transmission
(data) rate. When the communication quality drops below a certain level, the G-162 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 G-162 gradually increases the transmission (data) rate
again until it reaches the highest available transmission rate.
You can select any of the above options. If you wish to balance speed versus reliability, select 54 Mbps in
a networking environment where you are certain that all wireless devices can communicate at the highest
transmission (data) rate. 1 Mbps or 2 Mbps are used often in networking environments where the range of
the wireless connection is more important than speed.

Your G-162 can transmit at the proprietary transmission rates of 22Mbps or up to

125 Mbps when connected to the ZyXEL g+ AP or wireless router. Actual speeds

attained also depend on the distance from the AP, noise, etc.

2.1.4 Wireless Network Application

Wireless LAN works in either of the two modes: ad-hoc and infrastructure.
