Wireless LAN Network
This chapter provides background information on wireless LAN network.
2.1 Wireless LAN 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 (Tx Rate)
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.
