Octopus Series Wireless LAN Card WWW.TwinMOS.COM Page 4WIRELESS NETWORK OVERVIEW A wireless local area network (LAN) is a flexible data communications system implemented as an extension to, or as an alternative for, a wired LAN. Using radio frequency (RF) technology, wireless LANs transmit and receive data over the air, minimizing the need for wired connections. Thus, wireless LANs combine data connectivity with user mobility. A local area network that transmit and receive over the air typically in an unlicensed frequency such as the 2.4GHz band. A wireless LAN does not require lining up devices for line of sight transmission like IrDA. Wireless access points (base stations) are connected to an Ethernet hub or server and transmit a radio frequency over an area of several hundred to a thousand feet which can penetrate walls and other nonmetal barriers. Roaming users can be handed off from one access point to another like a cellular phone system. Laptops use wireless modems that plug into an existing Ethernet port or that are self contained on PC cards, while stand-alone desktops and servers use plug-in cards (ISA, PCI, etc.). Wireless LANs offer the following productivity, convenience, and cost advantages over traditional wired networks： Mobility - WLAN provide LAN users to access data in any location within the operating range of the WLAN. Ad-hoc management decisions based on real-time information can significantly improve worker efficiency. Installation Speed and Simplicity - Installing a wireless LAN system can be fast and easy and can eliminate the need to pull cable through walls and ceilings. Installation Flexibility - Wireless technology allows the network to go where wire cannot go. Reduced Cost-of-Ownership - While the initial investment required for wireless LAN hardware can be higher than the cost of wired LAN hardware, overall installation expenses and life-cycle costs can be significantly lower. Long-term cost benefits are greatest in dynamic environments requiring frequent moves and changes. Scalability - Wireless LAN systems can be configured in a variety of topologies to meet the needs of specific applications and installations. Configurations are easily changed and range from peer-to-peer networks suitable for a small number of users to full infrastructure networks of thousands of users that enable roaming over a broad area. Installation Considerations Designed to go up to 300 feet (100 meters) indoors and up to 900 feet (273 meters) outdoors, Octopus WLAN card lets you access your network from virtually anywhere you want. Keep in mind, however, that the number and thickness of walls, ceilings or other objects that the wireless signals must pass thru may limit range. Typical ranges vary depending on the types of materials and background RF noise in your home or business. The key to maximizing range is to follow these basic principles:
Octopus Series Wireless LAN Card WWW.TwinMOS.COM Page 5Keep the number of walls and ceilings between the access point and your receiving device to a minimum - Each wall or ceiling can reduce your TwinMOS Octopus Wireless product’s range from 3-90 feet (1-30 meters.) For some businesses or for a large residential home deployment, it may be more beneficial to have more than one access point with overlapping coverage. 1. Be aware of the direct line between Access Points, Residential Gateways, and Computers - A wall that is 1.5 feet thick (.5 meters), at a 45-degree angle appears to be almost 3 feet (1 meter) thick. At a 2-degree angle it looks over 42 feet (14 meters) thick! Try to make sure that the Access Points and Adapters are positioned so that the signal will travel straight through a wall or ceiling for better reception. 2. Building Materials make a difference - A solid metal door or aluminum studs may have a negative effect on range. Try to position Access Points, Residential Gateways, and Computers so that the signal passes through drywall or open doorways and not other materials. 3. Make sure that the antenna is positioned for best reception by using the software signal strength tools included with your product. 4. Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices that generate RF noise, like microwaves, monitors, electric motors, etc. For the average residence, range should not be a problem. If you experience low or no signal strength in areas of your home that you wish to access, consider positioning the Access Point in a location directly between the Residential Gateways and/or Computers that will be connected. Additional Access Points can be connected to provide better coverage in rooms where the signal does not appear as strong as desired. Using radio frequency (RF) technology, WLANs transmit and receive data over the air, minimizing the need for wired connections. Thus, WLANs combine data connectivity with user mobility, and, through simplified configuration, enable movable LANs.
Octopus Series Wireless LAN Card WWW.TwinMOS.COM Page 6Octopus WIRELESS NETWORK SCENARIOS The Octopus WLAN Card enables you to:  Connect your computer to a Ad-Hoc workgroup of wireless computing devices (see Figure 1-1 on page 7).  Connect your computer to a Small Office/Home Office (SOHO) network that includes a Residential Gateway (RG) access point (see Figure 1-2 on page 8).  Connect your computer to a Local Area Network (LAN) Infrastructure that includes Access Points, or other IEEE 802.11 compliant LAN systems (see Figure 1-3 and Figure 1-4).  Expand the capabilities of your Access Points, to support wireless devices that have been equipped with Octopus WLAN Card. Ad-Hoc Workgroup The Ad-Hoc workgroup configuration enables you to quickly set up a small wireless workgroup, where the workgroup participants can exchange files using features like “Files and Printer Sharing” as supported by Microsoft Networking. Figure 1-1 Ad-Hoc Wireless Workgroup You can use this option to setup a temporary or ad-hoc network in environments where no access points are available (for example in Small Office/Home Office (SOHO) environments). As long as the stations are within range of one another, this is the easiest and least expensive way to set up a wireless network.
Octopus Series Wireless LAN Card WWW.TwinMOS.COM Page 7Home Networking With the TwinMOS Octopus WLAN card, wireless access to the Internet or other computers is at your fingertips. All you need to do is connect the wireless computers to an external cable, an xDSL or a ISDN modem and you are ready to：  Share files and printers, and  Access the Internet Figure 1-2 Connect to a Residential Gateway (RG) Enterprise Networking With the 11 Mbps Wireless LAN access point you can connect to a corporate Local Area Network (LAN) infrastructure to have wireless access to all network facilities.

Octopus Series Wireless LAN Card WWW.TwinMOS.COM Page 17Status Tab The Status menu displays information on the current status of your connection to the wireless LAN. You can display this menu by choosing the Wireless Network Status... command from the pop-up menu, or by clicking on the Status tab when the Configuration Utility is displayed on your desktop. The fields in this menu provide the following information: •State: shows the association state of your computer with the wireless LAN. Possible values for this field are: •AdHoc: The adapter is operating in Peer-to-Peer mode. This field also shows the virtual MAC address used by computers participating in the AdHoc network. •Associated: The adapter is operating in Infrastructure mode. This field also shows the MAC address of the Access Point with which you are communicating. •Listening: Indicates that the adapter is listening on all allowed channels, but has not yet found a peer-to-peer or infrastructure network with which to associate. •Stopped: The radio has been stopped by the Disable Radio Button. •Scanning: The adapter is scanning for transmissions by other wireless adapters on all channels. •Associating: The adapter is in the process of associating with a network •Not Associated: The adapter has not found any network with which to associate. •Hardware Radio Switch OFF: The radio has been disabled by moving the hardware radio switch to the off position. Note that not all adapters have a hardware switch. •Current Tx Rate: shows the current transmit rate of the current association.
Octopus Series Wireless LAN Card WWW.TwinMOS.COM Page 18 •Current Channel: shows the channel on which the connection is made. In Infrastructure mode, this number changes as the radio scans the available channels. •Throughput: shows the short term transmit and receive throughput in bytes/second, and is continuously updated. •Link Quality: is based on the quality of the received signal of the Access Point beacon. •Signal Strength: is based on the received signal strength measurement of the baseband processor of the Beacon signal. You can click the Disable Radio button to turn off the wireless radio. When you click this button, the State field indicates that the radio has been stopped and the remaining fields in this window display either a zero or Not Applicable. Click this button again to turn the radio back on. However, if the radio has been disabled by the hardware switch on the adapter, clicking this button displays a popup message telling you that the radio cannot be enabled. You can click the Rescan button to force the radio to rescan all available channels. If your link quality or signal strength is poor, rescanning can be used to push the radio off a weak Access Point and search for a better link with another Access Point. Configuration Tab The Configuration menu lets you specify the operating parameters for your Octopus WLAN Interface adapter. You can display this menu by choosing the Advanced Configuration ... command from the pop-up menu, or by clicking on the Configuration tab when the Configuration Utility is displayed on your desktop.
Octopus Series Wireless LAN Card WWW.TwinMOS.COM Page 19 Profile Name A profile is a named set of operating parameters for your Octopus WLAN adapter. The Profile Name: field lets you set values for all parameters by selecting a previously defined profile. Click the down arrow at the right of this field to display the available profiles for your PRISM WLAN Interface adapter. You will always have at least one profile, named Default. Initially, this profile contains the parameters configured at installation. You can modify this profile at any time after the installation. After changing parameters, you can save them in the profile named in this field by clicking the Apply button in the Configuration Utility panel. You can also create additional profiles by typing a name in the Profile Name: field. When you change the name in this field and then click the Apply button, the Configuration Utility uses the current parameters for your adapter to create a separate profile. You can then switch between profiles by clicking the down arrow at the right of the Profile Name: field, selecting a profile from the drop-down list, and clicking the Apply button. The following example describes a situation in which you would want to create multiple profiles. Suppose that you use the wireless LAN at your work, but you also have a network in your home (with a wireless Access Point) for sharing an internet connection and a printer between several computers. Suppose also that you have another office within your business which also has WLAN capability, but which is configured differently than your main office. In this situation, you can create a different profile for each of these three environments. Each profile specifies the parameters used on a single network. Moving from one location to another, you need only apply the appropriate profile to be able to participate in the local network.  Network Name Officially, in wireless networks the network name is known as the SSID (Service Set IDentifier), and is used by Access Points and stations to identify a wireless LAN. Your PRISM WLAN Interface adapter scans the available channels looking for an Access Point or another station which has specified this same SSID. It then attempts to associate with these Access Points or stations to form a wireless LAN. To change the SSID, simply highlight it, type the new SSID, and click the Apply button. In typical infrastructure applications a company will use a single SSID for all Access Points. If the radio is scanning and cannot find a channel when an Access Point is known to be in range, verify that the Network Name is set correctly.  Network Type The Octopus WLAN adapter can operate in one of two types of networks, which are specified in the Network Type: field of the Configuration menu. Clicking the down arrow at the right of this field displays the available types. Peer-to-Peer IEEE 802.11, the standard on which the WLAN protocol is based, defines two modes to handle two separate needs. The first, called AdHoc (or IBSS) mode, is used when two or more wirelessly-enabled PCs exchange data directly, without an Access Point. In this case the PCs can establish a peer-to-peer
Octopus Series Wireless LAN Card WWW.TwinMOS.COM Page 20network in which they are the only members and over which they can exchange data. To exchange data, each computer participating in the AdHoc network must specify the same Network Name in this menu. Peer-to-Peer networks operate on a single communications channel. You specify the channel on which your adapter communicates in an IBSS network either in this menu or through either the Bands Menu or the IBSS Menu. Note also that IBSS operation is incompatible with the 802.11d standard. If your adapter supports 802.11d operation, you must disable 802.11d support through the Domain Menu Access Point The second mode defined by the IEEE 802.11 standard is called infrastructure mode, and is the primary application for WLAN operation. In this mode all data on the wireless network is directed to an Access Point, which then routes the data to the appropriate wireless station. The Access Point may also be configured to allow data to be bridged from the wireless network to wired networks. To participate in a wireless LAN in infrastructure mode, every station and Access Point must specify the same Network Name. In infrastructure mode, all available channels are scanned for traffic, so there is no need to specify a channel. Encryption Tab The Encryption menu lets you enable encryption and set the encryption keys. To see the available encryption methods, click the down arrow at the right of the Encryption (WEP security) field.
Octopus Series Wireless LAN Card WWW.TwinMOS.COM Page 21There are two encryption methods available. The IEEE 802.11 specification defines Wired Equivalent Privacy (WEP) using a 64-bit key. This capability was extended by the industry to allow a 128-bit key. If you specify an encryption method, you will only be able to communicate with Access Points and stations that use the same encryption method and keys. Disabling encryption To disable encryption, click the down arrow at the right of the Encryption field, select Disabled, and click the Apply button. Enabling encryption To enable encryption, click the down arrow at the right of the Encryption field, select either 64 bit or 128 bit, and click the Apply button. After enabling an encryption method, you must then specify encryption keys, as described in the following sections. Creating Encryption Keys Manually When you specify either 64-bit or 128-bit encryption, the Configuration Utility selects Create Keys Manually, and allows you to enter keys as either alphanumeric or hexadecimal characters. When you click one of these buttons, the cursor appears in the field for Key 1. For 64-bit encryption, you must type exactly 5 alphanumeric or 10 hexadecimal characters in each of the four key fields; for 128-bit encryption, you must type exactly 13 alphanumeric or 26 hexadecimal characters. You then click the Apply button to create your encryption keys. After you click the Apply button, the Configuration Utility uses asterisks to mask your keys. The Use WEP Key field lets you specify which of the four encryption keys you use to transmit data on your wireless LAN. You can change the default key by clicking on the down arrow at the right of this field, selecting the number of the key you want to use, and then clicking the Apply button. As long as the Access Point or station with which you are communicating has the same key in the same position, you can use any of the keys as the default. Creating Encryption Keys Using a Passphrase To create encryption keys using a passphrase, click the radio button next to Create Key with Passphrase and type a character string in the Passphrase field. As you type, the Configuration Utility displays asterisks to mask your passphrase and uses an algorithm to generate four keys used for encryption.Using a passphrase to generate the four keys makes it easy to set the same keys for all members of your wireless LAN.
Octopus Series Wireless LAN Card WWW.TwinMOS.COM Page 22IBSS Tab When communicating in a peer-to-peer network, you may specify a channel on which you prefer communications to take place. To specify a channel, click on the channel to select it, and then click the Apply button. Note that this is not necessarily the channel on which peer-to-peer communications will be established. If the IBSS network names (SSID) are the same for nodes in the peer-to-peer network but they have different preferred channels, a network can still be established. In this case, if it cannot find a network with the specified network name on the preferred channel, a station will scan other channels until it finds a peer-to-peer network with the specified network name on which to communicate. If you specified Access Point as the network type (in the Configuration Tab), choosing a channel in this field has no effect until you change the network type to Peer-to-Peer.
Octopus Series Wireless LAN Card WWW.TwinMOS.COM Page 23Domain Tab A domain refers to a territory in which radio frequency transmissions must conform to the standards set by a single regulatory agency. For example, in the United States, the allowed frequencies and channels for wireless data communications are set by the FCC. Every country is free to set its own standards, although in practice many countries may use the same standards. The IEEE 802.11d standard provides a means for a wireless LAN adapter to detect the domain in which it is located and conform its transmissions to the standards set by the controlling regulatory agency. Not all PRISM adapters include this mechanism, however, so the version of the Domain menu displayed by the Configuration Utility depends on the versions of driver and firmware for your adapter. 802.11d Not Supported If your Octopus adapter does not support 802.11d operation, the Domain menu simply provides a list of the domains established throughout the world for radio frequency transmissions. In most cases, these domains correspond to a single country. To see a list of the domains supported by your adapter, click on the arrow to the right of the Countries/Domains field. Use the arrows or the scroll bar to the right of the list to see the complete list of domains. Choose the appropriate domain for your location by clicking on its name in the list, and then click the Apply button. When you specify a domain, the Domain menu then displays information about the domain you chose. Use the arrows or the scroll bar to the right of the display to see the complete information, such as country code, domain name, and transmission standards (channels, frequencies, etc.) for the domain.
Octopus Series Wireless LAN Card WWW.TwinMOS.COM Page 24802.11d Supported If your PRISM adapter supports 802.11d operation, the Domain menu lets you specify one of three levels of 802.11d support. If you specify None in the 802.11d support field, you must then choose the county in the Countries/Domains field which corresponds to your location. In this case your adapter operates according to the standards set by the appropriate regulatory agency. Note: If you specify Peer-to-Peer as the network type, you must specify None in the 802.11d support field. If you choose Strict in the 802.11d support field, your adapter will only communicate with Access Points which provide 802.11d support. In this case, the adapter scans all communications channels for an Access Point which provides information on the channels, frequencies, and power levels permitted in your location. Once it finds such an Access Point, the adapter conforms its operations to these standards. The adapter will not communicate with an Access Point that does not provide this information, nor will it join or create a peer-to-peer network if Strict 802.11d support is specified in this field. If you choose Flexible in this field, your adapter can communicate with any Access Point it finds. In this case, you must also choose the county in the Countries/Domains field which corresponds to your location. Your adapter then searches for an Access Point which provides information on the channels, frequencies, and power levels permitted in your location. If it finds such an Access Point, the adapter conforms its operations to these standards. If it does not find an Access Point which provides this information, it then will establish communications with any Access Point it finds.
Octopus Series Wireless LAN Card WWW.TwinMOS.COM Page 25About Tab The About menu provides information on the version of the Network Driver, the Configuration Utility, and the firmware in the Octopus WLAN adapter.
