-7-1-3 System Configurations The 11Mbps Wireless 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.
-8-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.

-12-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 utility “Access Point Utility” provides a user-friendly interface. The ODU Utility enables you to configure all of your ODUs on the network more easily than ever before. The following gives instructions guiding you through the installations of the ODU Utility. 1. Insert the Product CD-ROM disk that came with your product kit into the corresponding drive on your computer. 2. From the Start menu on the Windows desktop, choose Run. 3. In the Run dialog box, type the path where the utility is located, then click OK. 4. Follow the on-screen instructions to install the Access Point Utility. 5. Upon completion, go to Program Files and execute the Access Point Utility. It will begin to browse all the ODU available on the network.
-13-6. Double click Access Point icon to access its property dialog box. Enter the password in the entry field. The default password is “default”. 7. After entering the correct password, a configuration window appears. You will see the basic information of the ODU, such as MAC Address, Frequency Domain and Firmware Version. MAC Address: It is a hardware identification number that distinguishes the unit from others. Frequency Domain: The regulated operating frequency per country. Firmware Version: Displays the firmware version that is equipped with your hardware. Statistics The statistics tab contains three of the following items for you to monitor the Ethernet and
-14-Wireless network traffic. Ethernet: You may monitor the TX/RX on the wired network. Wireless: You may monitor the TX/RX of the wireless network.
-15-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.
-16-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: Ø Wireless LAN Access Point (AP): Enables the ODU to act as a wireless bridge connecting to your network backbone. Ø Inter-building with Repeating (PxP): Allows for multi-point connection among LANs (default setting). Ø Station 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. Ø Station 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. Ø Station 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 PxP or 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.
-19-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). WEP64 Key Setting
-21- WEP128 Key Setting NOTE: The WEP key must be set up exactly the same on the ODU as they are on other wireless client stations. For example, if you set “MyKey” for the ODU, the same WEP Key “MyKey” must be assigned to other client stations. Upgrade This item is used for uploading the newest firmware of the ODU. You may either enter the file name in the entry field or browse the file by clicking the Open File button. For information about the release of the newest firmware, contact your local reseller. Access Control:
-22-With the Access Control enabled, you can authorize wireless units to access the Access Point by identifying the MAC address of the wireless devices that are allowed access to transmit data. Further more, the Bandwidth control function allows you to control the upstream/downstream bandwidth per client basis. Note that, only when the MAC addresses of the wireless stations are in the Access Control Table, they will be able to access network via Access Point. To create or edit the Access Control Table, do the following: Ø Go to the Access Control tab and check “Enable Access Control”. Ø Click the “Add” button and enter the MAC addresses of the wireless stations you allow to access. Ø Set “Up bandwidth”, “Down bandwidth” and “Total bandwidth” if needed. Specify the desired bandwidth or unlimited if you do not need the bandwidth control. Ø Click “Apply” to make the setting take effect. You can also configure the Access Control by using web-based management. NOTE: Be aware that, when you enable the Access Control Table without any MAC address in the table, no access is allowed to communicate with the Access Point. Use the following buttons to manage the Access Control Table: Add – to enter MAC addresses of authorized wireless devices one at a time. Edit – to change the entries in the table if you enter the incorrect MAC address. Remove – to remove MAC addresses one at a time. Clear – to remove all MAC addresses in the table. Import – to import an existing Access Control Table. Export – to save the current Access Control Table to a location on your computer. You may save the file as a text document. Advanced Security
-23-The 802.1x authentication (EAP) is designed to enhance the security of wireless networks. The 802.1x provides an authentication framework for wireless LANs, allowing a user to be authenticated by a central authority. For wireless LANs, it also provides centralized, server-based authentication of end users. The standard is flexible enough to allow multiple authentication algorithms, and because it is an open standard, multiple vendors can innovate and offer enhancements. For wireless LANs, the 802.1x authentication has three main components: The supplicant (usually the client software, such as zero configuration in window XP), the authenticator (usually the access point), and the authentication server (usually a Remote Authentication Dial-In User Service server, although RADIUS although 802.1X does not specify it). The advanced security describes how to control authorized access to the Access Point with Authentication Dial-In User Service (RADIUS). There are many ways to enhance your wireless security: 802.1x Based Auth mode or MAC Address Based Auth mode. To enable 802.1x based authentication, please select 802.1x Based Auth mode. Moreover, you may enable the radius account function by check Enable Radius Account in the check box. To configure the Authentication and Account Server function, the parameter of Radius Authentication Server and Radius Account Server must set to the same with the Authentication Server and Account Server. Before you enable RADIUS account, you have select 802.1x Based Auth mode first. Note: The Password is up to 16 bytes. If you want to use MAC Address Based authentication, you should select MAC Address Based Auth mode. However, the RADIUS account server will not be supported here. Most likely, the MAC Address Based authentication is less secure than 802.1x (EAP) authentication. MAC Address Based authentication provides an alternative for wireless 10 network security that does not support 802.1x capability. Otherwise, you may select disable auth mode that adjusts to the 802.11 legacy network. For setting 802.1x Based Auth:
