Page 6 11Mbps Wireless LAN PC Card User manual Wireless LAN 3. Wireless LAN Basics Wireless LAN (Local Area Networks) systems offer a great number of advantages over a traditional, wired system. Wireless LANs (WLANs) are more flexible, easier to setup and manage and often more cost effective than their wired equivalence. 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. With wireless LANs, users can access shared information without looking for a place to plug in and network managers can set up or augment networks without installing or moving wires. Wireless LANs offer the following productivity, convenience and cost advantages over traditional wired networks: •= Mobility - Wireless LAN systems can provide LAN users with access to real-time information anywhere in their organization. This mobility supports productivity and service opportunities not possible with wired networks. •= 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 wires cannot go. •= Reduced Cost-of-Ownership - While the initial investment required for wireless LAN hardware might be higher than the cost of wired LAN hardware, overall installation expenses and life-cycle costs will be significantly lower. Long-term cost benefits are greatest in dynamic environments requiring frequent moves, adds, 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 peerto-peer networks suitable for a small number of users to full infrastructure networks of thousands of users that allow roaming over a broad area.

Figure 1 Icon tray with a new icon Double clicking on that icon will show you the screen as shown below. Figure 2 Management window with “Status” tab open User can navigate through “sheets”, by clicking or tapping them with a stylus. “OK” button will minimize window, and “Cancel” (or X button) will close application. Here we explain the use and meanings of the various screen messages. User's manual 17 11 Mbps Wireless LAN PC Card Page Wireless LAN Link Info State This field is used to display the current state of the driver. When the state is “Associated “ means normal flow of operation in Infrastructure mode. The PC is connected to access point. BSSID is shown in the form of hex digits. Networking is available. A state of “Scanning ” means that the node is searching for available access point and cannot detect the SSID for an access point within range. This field will also display an error message if for some reason the driver failed to initialize. Rescan Pressing the rescan button causes the driver to restart and begin its Connection Procedure. The connection procedure differs depending on the Mode of the driver. Infrastructure Mode - The driver will scan all available channels continuously until it finds one or more Access Points that matches its SS ID. At that point it will try and authenticate and associate with the Access Point. 802.11Ad Hoc Mode - The driver will scan for 5 seconds looking for an existing 802.11Ad Hoc network using the same SS ID. If one is not found the driver will start its own 802.11Ad Hoc network. Current Channel and Tx Rate Shows the channel of the radio and transmit rate are being currently used for an active connection. This value has no meaning when the radio is “Scanning” Throughput These two fields display the instantaneous wireless Receive and Transmit throughput displayed in bytes per second. These values are updated every two seconds. Link Quality The Link Quality bar graph is only active when the node is in Infrastructure Mode. The bar graph displays the quality of the link between the node and its Access Point. A label summarizes the quality of the link over the bar graph, which can take on one of the following values: “Poor” “Weak” “Fair” “Good” “Excellent” Page 18 11Mbps Wireless LAN PC Card User manual Wireless LAN The driver will start looking for a better Access Point if the Link Quality becomes “Poor”. Link Quality is a measure of receives and transmits errors over the radio. Signal Strength The Signal Strength bar graph is only active when the node is in Infrastructure Mode. The bar graph displays normalized signal strength as reported by the radio, averaged over all frames over 100 bytes long that are received from the Access Point. User's manual 19 11 Mbps Wireless LAN PC Card Page Wireless LAN “CONFIGURATION” tab The Configuration Tab contains several fields where operating parameters of the driver can be viewed or changed. Changes to any of the parameters in this panel can be applied to the driver without the need to reboot the PC. Figure 4 Management window with "CONFIGURATION" tab open Restore Defaults:Pressing this button restores each field in the panel to its default value. The Apply Changes button or OK must be pressed before the default values are saved to the driver and registry. Undo Changes: Pressing this button reverts all fields in the panel back to their original values that were present when the Configuration Utility was opened from the Task Bar. Apply Changes: This button becomes active only when one of the fields has been modified. Pressing this button applies the changed values to the driver and saves them to the registry for the next time the PC boots up. Page 20 11Mbps Wireless LAN PC Card User manual Wireless LAN Mode This field allows you to select from a list of supported Network “Modes”. The modes displayed will have three values: “802.11Ad Hoc”, and “Infrastructure”. 802.11 Ad Hoc - This is the 802.11 peer-to-peer mode of operation. In 802.11Ad Hoc only one wireless “cell” is supported for each different SSID. All communication is done from Client to Client without the use of an Access Point. 802.11 Ad Hoc networking uses the same SSID for establishing the wireless connection. Infrastructure - This mode of operation requires the presence of an 802.11 Access Point. All communication is done via the Access Point, which relays packets to other wireless Clients in the BSS as well as to nodes on a wired network such as Ethernet. TX Rate – The transmission rate at which client of AP transmits the data packets. You can set this to fixed 1Mbps, fixed 2 Mbps, fixed 5.5 Mbps or 11 Mbps. PS Mode - Power saving mode. User's manual 21 11 Mbps Wireless LAN PC Card Page Wireless LAN “ENCRYPTION” tab Figure 5 Management window with “Encryption” tab open You may desire an additional measure of security on your wireless network, which can be achieved by using WEP (Wired Equivalent Privacy) encryption. WEP encrypts each frame transmitted from the radio using one of the Keys entered from this panel. When an encrypted frame is received it will only be accepted if it decrypts correctly. This will only happen if the receiver has the WEP Key used by the transmitter. This panel allows the entry of four keys for 64-bit encryption and one set of 128-bit key according to WEP function select. To be written to the driver and registry, each key must consist of hex digits, which means that only digit 0-9 and letters A-F are valid entries. If entered incorrectly program will not write keys to a driver. Alternatively a Pass-phrase can be entered which is used as a “seed” to randomly generate the four keys. This saves considerable time since the same keys must be entered into each node on the wireless network. Page 22 11Mbps Wireless LAN PC Card User manual Wireless LAN Key 1 – Key 4 These four fields can be used to manually enter the keys. This may be necessary if you wish this node to match keys in a different vendor’s product. These fields also display the keys when they are generated using a Pass-phrase. Default TX Key This button updates the driver with the four keys displayed in Key1 through Key4. The keys are also written to the registry for permanent storage. For 128-bit encryption, this button will be invisible. Apply This button updates the driver with the four keys displayed in Key field. The keys are also written to the registry for permanent storage. This button clears all the bytes in the four keys, useful when manually entering and you wish to start over.
