1-3 System Configurations
The 11MbpsWireless LAN ODU can be configured in a variety of network system
configurations.
Wireless Infrastructure
In a wireless infrastructure, the ODU can act as a bridge. The ODU connects the wireless
clients together. The ODU acts as a center point for all wireless communications. This
would increase efficiency of the communications since the wireless adapters do not need to be
within direct range of each other.
Wireless Infrastructure with Stations Attaching to a Wired LAN
The 11Mbps Wireless LAN ODU will provide an access to the local LAN. An integration of
wireless and wired LAN is called an Infrastructure configuration. A group of wireless LAN
PC users and an ODU construct a Basic Service Set (BSS). Each wireless PC in this BSS
can talk to each other on your network via the ODU.

-
Point-to-Point/Point-to-Multipoint Connection
The 11Mbps Wireless ODU provides ideal bridging solution for inter-building LANs
connection. In an inter-building application, the 11Mbps ODU acts as a repeater, thus
expanding and connecting corporate LANs with reliable and high speed connection.

Chapter 3 Configuring the ODU
The 11Mbps Wireless LAN ODU is shipped with default parameters, which will be suitable
for the typical Point-to-Point and Point-to-Multipoint. You can still adjust configuration
settings depending on how you would like to manage your wireless network. The 11Mbps
Wireless ODU allows for configuration either via the configuration utility, known as Access
Point Manager, TCP/IP (Telnet) connection or Web Management.
3-1 Configuration
Installed on your Windows 95/98/NT/ME/2000/XP desktop computer, the Windows-based

Wireless Error:
This item offers detailed information on error wireless packets that the ODU receives and
transmits.
Receive:
Packet FCS Errors: The number of wireless packets that fail during FCS transmission (Frame
Check Status when accessing the wired network.
No Buffer: The number of wireless packets that the ODU ignores due to insufficient memory.
Received WEP Errors: The number of wireless packets that have WEP encryption errors.
Transmit:
Deferred Transmission: The number of packets that have deferred transmission due to the fact
that the medium is busy.
Retry Limit Exceed: The number of packets that are not sent due to the reason that the packets
exceed the retry limits.
Single Tries: The number of packets that are successfully sent on the first retry.
Multiple Retries: The number of packets that are successfully sent after several retries.
Wrong Source Address: The number of packets that are ignored by the ODU because the
source client is not in its BSS.
Other reasons: Other reasons that cause errors.

Configuration
The configuration tab contains 5 following items for you to make changes for the ODU.
General:
AP name: In this entry field, you may enter any name. This will enable you to manage your
ODU with more ease if you have multiple ODU on the network.
IEEE802.11:
Radio Mode: The Wireless LAN ODU can operate total of 5 radio modes:
ØWireless LAN Access Point (AP): Enables the ODU to act as a wireless bridge
connecting to your network backbone.
ØInter-building with Repeating (PxP): Allows for multi-point connection among LANs
(default setting).
ØStation Adapter –Infrastructure (SAI): Served as a wireless station (infrastructure).

-17
-
Connect the ODU (SAI) to a PC with a cross over RJ-45 cable, and it is able to access
the network via ODU.
ØStation Adapter –Ad-Hoc (SAA): Served as a wireless station (Ad-hoc). Connecting to
a PC with a cross-over RJ-45 cable, the station adapter along with other wireless stations
can establish a small wireless network without ODUs.
ØStation Adapter –802.11 Ad-Hoc (SAA2): Similar to SAA, the ODU acts as a wireless
stations (Ad-Hoc). The only difference is that this Ad-Hoc mode complies with 802.11
standard.
NOTE: When setting the operation mode to either PxPor SAA, you need to set the ODU
with the same channel. ESSID however can be ignored. When the SAA2 is selected,
you need to set the ODU the same ESSID and channel.
ESSID: The ESSID is a unique ID given to the ODU. Wireless clients associating to the
ODU must have the same ESSID. The ESSID can have up to 32 characters.
Channel:You may select any of the available channels as an operational channel for your
ODU. You may use the Site Survey tool came with the wireless PC Card utility to monitor
each channel and choose a channel with good quality.
RTS Threshold:RTS Threshold is a mechanism implemented to prevent the “Hidden
Node” problem. “Hidden Node” is a situation in which two stations are within range of the
same ODU, but are not within range of each other. Therefore, they are hidden nodes for
each other. When a hidden station starts data transmission with the ODU, it might not notice

-18
-
that another station is already using the wireless medium. When these two stations send data
at the same time, they might collide when arriving simultaneously at the ODU. The collision
will most certainly result in a loss of messages for both stations. Thus, the RTS Threshold
mechanism will provide the solution to prevent data collisions. When the RTS is activated,
the station and its ODU will use a Request to Send/Clear to Send protocol (RTS/CTS). The
station will send an RTS to the ODU, informing that it is going to transmit the data. Upon
receipt, the ODU will respond with a CTS message to all station within its range to notify all
other stations to defer transmission. It will also confirm to the requesting station that the ODU
has reserved the channel for transmission.
Fragmentation Threshold:Fragmentation mechanism is used for improving the efficiency
when there is high traffic within the wireless network. If you transmit large files in a
wireless network, you can enable the Fragmentation Threshold and specify the packet size.
The mechanism will split the packet into the packet size you set.
TX Rate: When the ODU is under PXP, SAI, SAA, and SAA2, it provides various data rate
options for you to select. Data rates options include Fully Auto, Fixed 1Mb/s, Fixed 2Mb/s,
Auto Select 1M or 2M, Fixed 5.5Mb/s, and Fixed 11Mb/s.In most networking scenarios,
you will see that the factory-set default “Fully Auto”will prove the most efficient. This
setting will allow your 11Mbps Wireless LAN ODU to operate at the maximum data rate as
possible. When the communications quality drops below a certain level, the ODU will
automatically switch to a lower data rate. Transmission at lower data speeds is usually more
reliable. However, when the communications quality improves again, the 11Mbps Wireless
LAN ODU will gradually increase the data rate again, until it has reached the highest
available transmit rate.

Administration:
You may change the default password by entering the new password. Enter the new
password in the Confirm Change field to make the new setting take affect.
IP Address:
To enable remote access to the ODU using Telnet or Web Management, you must assign an IP
address to the ODU. You may also assign other related Internet addressing options, such as
subnet mask or gateway address. Consult your network administrator to obtain an available
IP address. (Default setting is 192.168.1.1)
WEP:

-20
-
If data transmission with high security is required on your network, it is recommended that
the WEP encryption be used. To activate the WEP encryption, select Configuration, go to the
WEP tab, and do the following:
Pull down the WEP Encryption menu and select WEP64 or WEP128.
You may identify up to 4 different encryption keys and select one of them to encrypt your
transmission data. The key value of your choice may either be:
From the 4 Key entry field, enter the corresponding key value for each encryption method.
For WEP64 data encryption:
-- 5 alphanumeric characters in the range of “a-z”, “A-Z” and “0-9” (e.g. MyKey).
-- 10 digit hexadecimal values in the range of “A-F” , “a-f” and “0-9”, preceded by the
characters “0x” values (e.g. 0x11AA22BB33).
For WEP128 data encryption:
-- 13 alphanumeric characters in the range of “a-z”, “A-Z” and “0-9” (e.g. MyKey12345678).
-- 26 digit hexadecimal values in the range of “A-F” , “a-f” and “0-9”, preceded by the
characters “0x” values (e.g. 0x00112233445566778899AABBCC).
