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 WLAN PC users and an Access Point compose a Basic Service Set (BSS). Each WLAN 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 WLAN equipped PC to a wired LAN, and doubles the effective wireless transmission range for 2 WLANs PCs. Since the Access Point is able to forward data within its BSS, the effective transmission range in an infrastructure LAN is double.

The use of a unique ID in a BSS is essential. All WLAN 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.

The infrastructure wireless LAN configuration is appropriate for enterprise-scale wireless access to a central database, or as a wireless application for mobile users.

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 WLAN 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.

Before insert your card, please install the Auto-Install CD into your CD-ROM driver first. Unless you have deactivated the auto-run feature of Windows, the screen shown below should appear automatically.

Click Finish . The operating system will restart the computer automatically.

After the Configuration Utility has been installed, an icon will placed in the system tray when the WLAN CarBus PC Card is inserted.

The utility is divided into five parts: profile, Link State, Site Survey, Statistics, and about. You should change all your configuration settings for your WLAN PC Card using this utility and not with the Network Properties section in your Control Panel.

To add a new location profile name or to rename, delete, or select an existing profile, click Edit. The Edit Configurations screen appears

Edit profile

Network Type:

Ad Hoc: An Ad-Hoc wireless LAN is a group of computers each with wireless adapters, connected as an independent wireless LAN.

Infrastructure: An integrated wireless and wired LAN is called an infrastructure configuration.

SSID: All wireless devices within the ESS or extended wireless LAN use the SSID. This can be any alphanumeric value of up to 31 long. Use this to prevent cross communication between two or more WLAN in one area. The SSID should be changed in order to provide some minimum security.

Fragment Threshold: Fragment Threshold defines a threshold above, which the wireless packet will be split up, or fragmented. For a fragmented packet, if transmission of part of it were to be interfered with, only the portion that was successfully transmitted would need to be resent. Throughput will generally be lower for fragmented packets, since the fixed packet overhead consumes a higher portion of the RF bandwidth.

RTS Threshold: The RTS Threshold sets an upper threshold at which point the device will issue an RTS packet. The RTS (Request To Send) packet is used for the purpose of avoiding data collisions on the wireless LAN. There are several trade offs to consider when setting this parameter. Setting this parameter to a small value causes RTS packets to be sent more often, consuming more of the available bandwidth, therefore reducing the apparent throughput of other network packets. However, the more often RTS packets are sent, the quicker the system can recover from interference or collisions. Refer to the IEEE 802.11 Standard for more information on the RTS/CTS mechanism.

Power Save Mode:

CAM: (Constant Awake Mode) CAM is the normal mode for desktop machines or other machines where power consumption is not an issue. It keeps the radio powered up continuously, so there is little latency for responding to messages.

Max_PSP: Maximum Power Save.

Fast_PSP: Fast Awake.

Use Short Preamble: Preamble is the first sub-field of PPDU, which is the appropriate frame format for transmission to PHY (Physical layer). There are two options, Short Preamble and Long Preamble. The Short Preamble option improves throughput performance.

Transmit rate: By default, the unit adaptively selects the highest possible rate for transmission. Select the basic rates to be used among the following options: Auto, 1, 2, 5.5, or 11 Mbps. For most networks the default setting, Auto will be the best choice. When Auto (Rate Fall Back) is enabled the transmission rate will select the optimum rate. If obstacles or interference are present, the system will automatically fall back to a lower rate.

Encryption : A way of coding the information in a file or e-mail message so that if it is intercepted by a third party as it travels over a network it cannot be read. Only the person or persons that have the right type of decoding software can unscramble the message.

WEP : WEP (Wired Equivalent Privacy) is an optional feature of the IEEE 802.11 standard that is used to provide data confidentiality and is equivalent to that of a wired LAN that does not use crypto techniques to improve security.

Encryption:

WEP Key length: The 64 or 128-bits Wired Equivalent Privacy Algorithm. Use this enable 64-bit or 128-bit encryption. WEP is disabled by default. WEP use a Hexadecimal format as key type. The 64/128-bit key length minus the 24-bit IV actually gives an effective 40/104-bit key length.

Open System: With this setting any station in the Wireless LAN can associate with an Access Point to receive and to transmit data.

Key 1 - Key 4: These four fields can be used to manually enter the encryption keys. This may be necessary if you wish this node to match keys in a different vendor's product.

You can see the below status:

Status, Current Channel, Current TX Rate, throughput(Kbit/sec), Link Quality, Signal Strength.

Access Point- An internetworking device that seamlessly connects wired and wireless networks together.

Ad-Hoc- An Ad-Hoc wireless LAN is a group of computers each with wireless adapters, connected as an independent wireless LAN.

Bit- A binary digit. The value - 0 or 1 used in the binary numbering system. Also, the smallest form of data.

Backbone- The core infrastructure of a network, the portion of the network that transports information from one central location to another central location. The information in then off-loaded onto a local system.

BSS- Stands for Basic Service Set. An Access Point associated with several stations.

Domain- A subnetwork comprised of a group of clients and servers under the control of one security database. Dividing LANs into domains improves performance and security.

DSSS- Direct Sequence Spread Spectrum is very widely known and the most used of the spread spectrum types, owing most of its popularity to its ease of implementation and high data rates.

Encryption- A security method that applies a specific algorithm to data in order to alter the data´s appearance and prevent other devices from reading the information

ESS- Stands for Extended Service Set. More than one BSS can be configured as an Extended Service Set. An ESS is basically a roaming domain.

Ethernet- A popular local area data communications network, originally developed by Xerox Corp., which accepts transmission from computers and terminals.

Ethernet operates on 10 Mbps baseband transmission over shielded coaxial cable or over shielded twisted pair telephone wire.

Fragmentation- Breaking a packet into smaller units when transmitting over a network medium that cannot support the original size of the packet.

Infrastructure- An integrated wireless and wired LAN is called an infrastructure configuration.

IRQ- Interrupt ReQuest, A hardware interrupt on a PC. There are 16 IRQ lines used to signal the CPU that peripheral event has started or terminated. In most cases, two devices cannot use the same line.

Roaming- A function that allow one to travel with a mobile end system (wireless LAN mobile station, for example) through the territory of domain (an ESS, for example) while continuously connecting to the infrastructure.

RTS- Request to Send, An RS-232 signal sent from the transmitting station to the receiving station requesting permission to transmit.

Throughput- The amount of data moved successfully from one place to another in a given time period.
