The following list describes some of the many applications made possible through the power and flexibility of wireless LANs: 1. Difficult-to-wire environments There are many situations where wires can not or can not easily be laid. Historic buildings, older buildings, open areas and across busy streets make the installation of LANs either impossible or very expensive. 2. Temporary workgroups Consider situations in parks, athletic arenas, exhibitions, disaster-recovery, temporary office and construction sites where one wants a temporary WLAN established and removed. 3. The ability to access real-time information 2
Doctors/nurses, point-of-sale employees, and warehouse workers can access real-time information while dealing with patients, serving customers and processing information. 4. Frequently changed environments Show rooms, meeting rooms, retail stores, and manufacturing sites where the workplace is frequently rearranged. 5. Small Office and Home Office (SOHO) networks SOHO users need a cost-effective, easy and quick installation of a small network. 6. Wireless extensions to Ethernet networks Network managers in dynamic environments can minimize the overhead caused by moves, extensions to networks, and other changes with wireless LANs. 7. Wired LAN backup Network managers implement wireless LANs to provide backup for mission-critical applications running on wired networks. 8. Training/Educational Facilities Training sites at corporations and students at universities use wireless connectivity to ease access to information, information exchanges, and learning. 1- 6 Network Configurations To better understand how the SL-2011 PLUS wireless LAN products work together to create a wireless network, it might be helpful to depict a few of the possible SL-2011 PLUS network configurations. The SL-2011 PLUS wireless LAN products can be configured as: 1. Ad-hoc (or peer-to-peer) for departmental or SOHO LANs. 2. Infrastructure for enterprise LANs. 3. IP Sharing for 56K/ISDN TA/Cable/DSL Modem – Connect Internet and your SOHO network. Ad-hoc (peer-to-peer) Mode This is the simplest network configuration that several computers equipped with the PC cards that form a wireless network whenever they are within range of one another (Figure 1-3). In ad-hoc mode, each client, is peer-to-peer, would only have access to the resources of the other client and requires no the access point. This is the easiest and least expensive way for the SOHO to set up a wireless network. 3
Figure 1-3 A wireless Ad-hoc network Infrastructure Mode The infrastructure mode requires the use of an access point (AP). In this mode, all wireless communications between two computers have to be via the AP no matter the AP is wired to Ethernet network or stand-alone. If used in stand-alone, the AP can extend the range of independent wireless LANs by acting a repeater, which effectively doubling the distance between wireless stations as shown in Figure 1-4. Figure 1-4 Extended-range independent WLAN using AP as repeater 4 W/ EL-2011CDW/ EL-2011CDW/ EL-2011CDW/ EL-2011CDLPeer to PeerW/ EL-2011CDEL-2011APW/ EL-2011CD W/ EL-2011CDLLInfrastructure
If wired to an Ethernet network as shown in Figure 1-5, the AP serves as a bridge and provides the link between the server and the wireless clients. The wireless clients can move freely throughout the coverage area of the AP while remaining connected to the server. Since the AP is connected to the wired network, each client would have access to server resources as well as to other clients. Figure 1-5 Single AP bridge Access points have a finite range, on the order of 50 meters indoor and 100 meters outdoors. In a very large facility such as an enterprise, a warehouse, or on a college campus, it will probably be necessary to install more than one access point to cover an entire building or campus, as shown in Figure 1-6. In this scenario, access points hand the client off from one to another in a way that is invisible to the client, ensuring unbroken connectivity. Wireless clients can roam seamlessly between different coverage areas and remain connected to the network Figure 1-6 Multiple-AP and roaming 5 W/ EL-2011CDEL-2011APFile serverNetwork PrinterW/ EL-2011CDW/ EL-2011CDEnt e rn e tW/ EL-2011CD W/ EL-2011CDW/ EL-2011CDW/ EL-2011CDFile serverEnterpriseEthernetEL-2011AP EL-2011AP
Wireless Router and IP Sharing In infrastructure mode, in addition to acting as a bridge between an Ethernet and wireless network, the AP can be configured as a wireless router and IP sharing device for Internet access as shown in Figure 1-7. You don’t have to buy an expensive router. Nor you have to buy several modems and setup phone lines. Just share one AP, one Modem, single dial-up account, and one phone line, dozens of network users can go surfing the Internet concurrently.

Figure 2-6 1. Link Info State Shows status information about the radio link, as shown in Figure 2-6 # Associated BSSID – means the wireless client is connected to an access point. BSSID is shown in the form of six hex digits which is the MAC address of the access point. # Scanning – means the wireless client is searching for an available access point in infrastructure mode. # Disconnected – means there are no access points or other wireless clients (if communicating in Ad-hoc mode), or the PC Card is unplugged in your computer. Current Channel Shows the operation radio frequency channel that the wireless client is using in infrastructure mode. In infrastructure mode, wireless client will always go the same channel as their Access Point. Current Tx Rate (Mbits/s) The data speed that the wireless client is transmitting. Throughput (Bytes/sec) 12
# Tx: shows the outgoing (sent) data speed. # Rx: shows the incoming (received) data speed. Link Quality The bar shows the measured signal level and connection status. The higher blue bar is, the better the radio signal is being received by the PC card. Signal Strength The bar shows signal strength level. The higher blue bar is, the more powerful radio signal is received by the PC Card. 2. Configuration Mode Selects one of the following network mode, as shown in Figure 2-7. Figure 2-7 # 802.11 AdHoc: this is the IEEE802.11 peer-to-peer mode of operation and requires no Access Point. When wireless clients are operating in this mode, all wireless clients require the same SSID and the channel number is not important. # AdHoc: this is non-standard peer-to-peer mode of operation and requires no Access Point. When wireless clients are operating in this mode, all wireless clients require the same channel number ,and the SSID is not 13
important # Infrastructure: this mode of operation requires the use of an Access Point. In this mode, all wireless communications between computers have to be via the Access Point. (Default setting is Infrastructure) SSID SSID is an identification code required for communication in a wireless LAN. You will only be able to connect with a wireless client (802.11 AdHoc) or an Access Point (Infrastructure) which has the same SSID. If the SSID of a PC Card is set as any, then the PC Card can connect to all available Access Points. (Default setting is IEEE802.11) Tx Rate Select the transmission rate at which the data packets are transmitted by the client. You can set this to Fully Automatic, 1Mbps, 2Mbps, Auto 1 or 2Mbps, 5.5Mbps, or 11Mbps. (Default setting is Fully Automatic) PS Mode Power saving management, disabled or enabled. (Default setting is Disabled) Channel Select the operating radio frequency channel in 802.11 AdHoc or AdHoc mode. 3. Encryption If you require high security in transmission, you can select the 64 or 128-bit WEP (Wired Equivalent Privacy) key to encrypt data (Default setting is Disable) as shown in Figure 2-8. WEP encrypts each frame transmitted from the radio using one of the Keys from this panel. When you use WEP to communicate with the other wireless clients, all the wireless devices in this network must have the same encryption key or passphrase. 14
Figure 2-8 This panel allows the entry of keys or passphrases, which can then be written to the driver and registry. Note that each key must consist of hex digits, it means that only digit 0-9 and letters A-F are valid entries. If entered incorrectly, program will not write the keys to a driver. 4. About The About tab shows the product/driver/utility/PC Card firmware version as shown in Figure 2-9. Users have to use this version number when reporting their problems to technical support. 15

Chapter 4 Troubleshooting This chapter describes the problems and corresponding solutions that may occur when installing a PC Card. Symptom Solution Windows does not detect the PC Card when installed. Verify that the PC Card is properly inserted into the PC Card slot. Check whether the computer has a Plug and Play BIOS. Windows 95/98/ME/2000 might not detect the PC Card if a previous installation of the PC Card was cancelled before it was finished. Remove the previous driver, and redo the installation again. Driver fails to load A resource conflict could exist. For Windows 95/98/ME/2000, use the Device Manager to resolve resource conflicts. Select System from the Control Panel, then click on the Device Manager tab. For Windows NT4.0, use the Service Monitor entries in the System Log to look for the conflicts. Use the NT diagnostics program to locate free resources. 21
Device conflict on a Windows system A device conflict under Windows 95/98/ME/2000/NT may be related to the PC Card. For Windows 95/98/ME/2000, use the Computer properties to identify the used I/O port addresses and IRQ values. For Windows NT4.0, use the Windows NT diagnostics program to detect the cause of the card conflict and to deter- mine unused I/O port addresses and IRQ values. If there is a device conflict, select alternative settings for I/O Base Address or IRQ values. If you know which device is conflicting with the PC Card, you have the option of changing that device’s I/O address or IRQ instead of changing the PC Card. No resource conflicts were detected, but the wireless station does not attach to the network Verify that the SSID of the PC Card matches that of the access point. Use the Network Configuration Properties Application in the Control Panel to modify the SSID. Verify that the Network Mode of the PC Card is configured correctly. 22
Nonfunctioning card LEDThe PC Card is not powered on. The cause may be: # No Driver loaded or installed. # Card – Driver mismatch which prevented the driver from loading. # Device conflict which prevented the driver from loading. Actions: # Verify that a driver has been installed. # Determine if there is a conflict with another device. Weak signal or intermittent connection. Try reorienting the antenna. The PC Card antenna is attached to the end of the PC Card. For best use of the antenna: Keep the area around the antenna clear from materials that could block radio transmission, such as metal objects, electronic devices, and cordless telephones. If your signal is weak, change the direction of the antenna slightly. If necessary, move your notebook computer a few inches to find a better signal. Use the Link Quality and Signal Strength display in the Client Utility to determine the best location and orientation for a network connection. 23
