2 Network Configuration and Planning
2.1 Wireless LAN Basic
The adapter supports legacy Ethernet LAN network configuration options as defined by the IEEE
802.11b standards committee.
The adapter can be configured as:
Ad-Hoc for departmental or SOHO LANs.
Infrastructure for enterprise LANs.
LAN-Interconnection for point-to-point link as campus backbone.
2.2 Network Topology
Fig 2-1 Ad-Hoc Wireless LAN
An Ad-Hoc wireless LAN is a group of computers, each equipped with one WLAN adapter,
connected as an independent wireless LAN. Computers in a specific Ad-Hoc wireless LAN must
be configured to share the same radio channel.
9
Fig 2-2 Infrastructure Wireless LAN
The adapter provides access to a wired LAN for wireless workstations. An integrated wireless
and wired LAN is called an infrastructure configuration. A group of adapter PC users and an
Access Point compose a Basic Service Set (BSS). Each adapter PC in a BSS can talk to any
computer in the wired LAN infrastructure via the Access Point.
An infrastructure configuration extends the accessibility of a adapter equipped PC to a wired
LAN, and doubles the effective wireless transmission range for 2 adapter PCs. Since the Access
Point is able to forward data within its BSS, the effective transmission range in an infrastructure
LAN is double.
Fig 2-3 The effective transmission range
The use of a unique ID in a BSS is essential. All adapter equipped PCs configured without
roaming options in independent BSS must be configured with a BSS ID corresponding to the
Access Point used in the BSS. Check your Access Point for its BSS ID or use the Access Point
Browser Utility program to determine the BSS ID
10
The infrastructure wireless LAN configuration is appropriate for enterprise-scale wireless access
to a central database, or as a wireless application for mobile users.
2.3 Roaming
Fig 2-4 Roaming in an Extended Service Set (ESS)
Infrastructure mode also supports roaming capabilities for mobile users. More than one BSS can
be configured as an Extended Service Set (ESS). The continuous network allows users to roam
freely within an ESS. All adapter PCs and Access Point within one ESS must be configured with
the same ESS ID.
Before enabling an ESS with roaming capability, it is recommended to select a feasible radio
channel and optimum Access Point position. Proper Access Point positioning combined with a
clear radio signal will greatly enhance performance.

Ad-Hoc or Infrastructure Mode depending on your network type. The Ad-Hoc mode is used for
simple peer-to-peer network and allows the sharing of local resources only between Network
Wireless Adapter without needing a Wireless Access Point. The Infrastructure mode allows a
wireless network to be integrated into an existed, wired network through an Access Point.
Infrastructure networks permit roaming between Access Points while maintaining a connection
to all network resources.
An acronym for Service Set Identifier, SSID is the unique name shared among all points in a
wireless network. The SSID must be identical for all points in the network. It is case sensitive
23
and must not exceed 32 characters.
The Tx Rate field shows the current transfer rate for the Wireless Network USB Dongle. To
optimize performance and range, the Tx Rate should be set to Auto, which will automatically

(1 to 4). The Disabled setting prevents the sharing of data with other computers on the WEP
network. When Enable encryption for the WEP Key entry, enter the hexadecimal number (the
letters “A” through “F” and the numbers “0” through “9”) set by the other wireless WEP
settings; these settings must be identical to the WEP encryption on all points in your wireless
network in order to network to your WLAN USB Dongle. The security keys are four 10 digit key
for the 64-Bit WEP setting and four 26 digit key for the 128-Bit WEP setting.
25
Fig 4-5
NOTE: The WEP Key Entry must match the Key on all other devices on the wireless network or
this device will be unable to transmit or receive data.
For Authentication Type, you may choose among Auto, Open System or Shared Key.
Shared Key is when both the sender and recipient share a secret key. Both units this key for an
extended length of time, sometimes indefinitely. Any eavesdropper that discovers the key may
decipher all packets unit the key is changed.
Open System the default setting, is when the sender and the recipient do not share a secret key.
Each party generates its own key-pair and asks the receiver to accept the (usually randomly)
generated key. Once accepted, this key is use for short time only: then a new key is generated
and agrees upon.
4.1.5 Advanced
The Advanced screen (Fig 4-6) allows you to set Fragmentation Threshold, the RTS/CTS
Threshold, and the Preamble Type. The Fragmentation Threshold Value indicates how
much of the network resources is devoted to recovering packet errors. The value should remain
at its default setting of 2,346. If you experience high packet error rates, you can decrease this
26
value but it will likely decrease overall network performance. Only minor modifications of this
value are recommended.
Fig 4-6
The RTS Threshold Value should remain at its default setting of 2,347. A preamble is a signal
used to synchronize the transmission timing between two or more systems. A series of
transmission pulses is sent before the data to indicate that “someone is about transmit data.” this
ensures that systems receive the information correctly when the data transmission starts.
The Preamble Type should be set to Short (if the network environment is “noisy”) or Long (if
the environment is “clear”) Click Submit to complete the configuration.
Power Save, you can select enabled then submit to allow your adapter to go to sleep mode
while theadapter doesn’t precede the data transmission. Or select disabled to make the adapter
nevergo to sleep mode. Click submit to save the settings.
