Chapter 1. Wireless LAN Network
1.1 Overview
This section describes the wireless LAN network terms and applications.
1.1.1 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.
1.1.2 Channel
A radio frequency used by a wireless device is called a channel.
1.1.3 Transmission Rate (Tx Rate)
The 802.11g USB 2.0 WLAN Dongle provides various transmission (data) rate options for you to
select. Options include Auto, 1 Mbps, 2 Mbps, 5.5 Mbps, 11 Mbps, 6 Mbps, 9 Mbps, 12 Mbps, 18 Mbps,
24 Mbps, 36 Mbps, 48 Mbps, and 54 Mbps. In most networking scenarios, the factory default Auto
setting proves the most efficient. This setting allows your WLAN Dongle to operate at the maximum
transmission (data) rate. When the communication quality drops below a certain level, the WLAN
Dongle 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 WLAN Dongle
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 48
Mbps or 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.
1.1.4 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 WLAN Dongle 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.
Ad-Hoc (IBSS)
Ad-hoc mode does not require an AP or a wired network. Two or more wireless stations
communicate directly to each other. An ad-hoc network may sometimes be referred to as an
Independent Basic Service Set (IBSS).

AP MODE
A series of overlapping BSS and a network medium, such as an Ethernet forms an Extended Service Set
(ESS) or infrastructure network. All communication is done through the AP, which relays data packets to
other wireless stations or devices connected to the wired network. Wireless stations can then access
resource, such as the printer, on the wired network.
Access Point Mode
The following figure depicts a network example in which you set the WLAN Dongle in access point mode.
In the example, the WLAN Dongle is installed on computer A and set to operate in access point mode.
Computer 1 shares Internet connection to the wireless LAN, so wireless computer 2 and 3 can access the
Internet.
