The minimum system configuration Will be the same as that required to run MS Windows (Win 95, Win NT 4.0, Win CE) andNovell Netware 3.1 and above. Software Environment The stations operate in conjunction with most ofthe MS Windows (Win 95, Win NT“), Win CE] and Novell NetWare series operating systems Network Topology A network is usually formed by several stations and one Access Point (AP), with the stations within a set distance from the AP. This is called an nfrastructure Network" (Figure 1). Pin? ISA/PC Card User’s Guide 1 tn / L i Station (PC) \ “1 Access is ‘ 4 \ oin‘ Station(PC) i Figure 1. An Infrastructure Network Any station in the LAN may communicate with any other station in the same LAN. The stations may also communicate with a station connected to another wired or wireless LAN through the AP, which functions as a bridge. Figure 2. An Ad Hat: Network A network can also function without an AP and is called an d Hoe" network (Figure 2). 2 Pin? ISA/PC Card User 's Guide The stations communicate via radiowaves to form a Local Area Netwurk (LAN). For the user, the shared resources on the wireless LAN will appear as they would on a regular wired LAN‘ The wireless operation of the LAN is totally transparent. Size of Network On an infrastructure network, one AP can serve 5-l0 stations for heavy users, and 20 stations for occasional users. On an Ad Hoc network there IS no actual limit to the number of stations that can be operational within the area ofthe Wueless LAN (WLAN).

All parameter changes are saved in the Windows 95 registry and are referred to by the WLAN driver when the Windows 95 system boots. Therefore, most of the parameter changes require a system reboot to make them effective. Changes to Power Saving, Roaming, and the Max Number of Data Transmission Rcuies, do not require a system reboot. Modifications to these parameters are saved in the MAC layer in the Windows 95 registry. The configuration dialog box is shown below ( PnP ISA/PC Card User's Guide 13 Figure 13). 14 PnP ISA/PC Card User‘s Guide Figure 13. Configuratlon - Network Type - The 8024 I Wireless Specifications allow for two types of network, Infrastructure or Ad an. Infrastructure is set when networking with an Access Point (AP). - Carrier Set - Selects the country carrier set to comply with national wireless regulations. 0 Domain Name (ESS ID) - Stations and APs in the same group must use the same domain name. This field is defined in the 802,11 Wireless Standard as ESS 1D (Extended Service Set ID), a Roaming - Enables/Disables the Roaming function. Roaming is enabled only when the adapter is configured for an Infrastructure network. When Roaming is enabled, the station will associate with an AP with the same domain name (1358 ID) 0 Sensitivity - Sets the Roaming sensitivity level. Low, Medium, and High correspond to 0%, 40%, and 80% signal reception. If the _______—————— PM? ISA/PC Card User’s Guid: 15 setting is set to ow” the station wlll not begin to scan for another AP until the current AP has gone off the air. Setting the sensitivity level to igh' causes the station to begin scanning for an Access Point (AP) with a better signal once the current beacon (signal) quality has dropped below 80%. o Pawer Saving - Enables/Disables MAC layer power savrng. The power saving function is implemented in the MAC layer in compliance with the 80211 Wireless Standard. It can only be enabled an a PC card adapter, If the WLAN card is an ISA PnP card this function will be disabled and the power saving mode will be set to off (Power savrng not enabled). - Max. Number afDatn Transmission Retries — Sets the maximum number of MAC layer data transmissron retries, Changes in this field will cause immediate changes in the MAC layer. - Preferred AP (BSS ID) - Typing an Access Point (AP) BSS ID in this field will cause the WLAN adapter to search for that particular AP only. If this field 15 left blank the WLAN adapter will search for the AP with the strongest signal within its domain a Click OK to close the window and then reboot your computer to make the changes effective. After rebooting open the WLAN utility again and click on the Tools menu item and then the Site Survey sub-item. Tools Site Survey Site Survey scans for all 1385 in range and displays each AP signal strength and quality. It gives users the option of selecting an Access Point to associate with, or to join manually. If the user chooses to associate with an Access Pomt (AP) the received signal strength and quality will he dynamically shown on the status hart l6 PnP ISA/PC Card User’s Guide Flgure 14. Site Survey when Site Survey is run the program first reads and displays information stored in the MAC layer database. Click Refresh to obtain and display updated data. You may need to wait a short time depending on the number of BSS replies received. Select one of the BSS IDs from the view list. This will enable the Join BSS button. When the Join BSS button 15 clicked the Utility program issues a command to the MAC layer to scan for andjoin the selected ESSA Once you have made a connection the Wireless Station Utility will automatically connect to the same AP each time it starts (unless the AP has gone off the air). If the scanning and joining can not be accomplished within 10 seconds (possibly due an AP that has gone off the air since the data was last refreshed, to RF interference, or a busy AP) the BSS of the MAC layer will enter into the FaiIed state (see ” , page 19). If this happens you may retry joining the same 1385 again, or select another BSS to join, If the AP has connected successfully, click on the Network Neighborhood icon and click on the server you wish to access. A screen will appear asking you to type in your user name and password.

The result is indicated as a percentage, calculated from the number of frames received, dividedby the number of frames expected, over the last 10 seconds. When the quality value is above 61%, the indication bar shows GREEN. If the quality drops to 31% - 60%, it shows as a YELLOW bar. However, if the quality is between 00% to 30%, it will warn users with a RED bar. These two statistics provide users with a reference when Signal transmission or reception appears to be poor: Strength is used for range reference, If Strength drops below 20, the signal quality becomes poor, indicating the distance between the AP and the station may be too great. The Quality value shows the received frame error rate; when Quality is displayed as 97%, the on—atr frame error rate is 3%. If Quality drops close to 80%, signal reception becomes poor. 2“ Pu?
