This chapter provides background information on wireless LAN network.

This section describes the wireless LAN network terms and applications.

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.

A radio frequency used by a wireless device is called a channel.

The G-170S provides various transmission (data) rate options for you to select. Options

include Fully Auto, 1 Mbps, 2 Mbps, 5.5 Mbps, 6 Mbps, 9 Mbps, 11 Mbps, 12 Mbps, 18

Mbps, 24 Mbps, 36 Mbps, 48 Mbps and 54 Mbps. In most networking scenarios, the factory

default Fully Auto setting proves the most efficient. This setting allows your G-170S to

operate at the maximum transmission (data) rate. When the communication quality drops

below a certain level, the G-170S 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-170S 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.

Note: Your G-170S can transmit at up to 108 Mbps when connected to an AP or

wireless router with the Super G feature enabled.

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