Introduction: Company 54g Wireless LAN (WLAN) User Manual Back to Contents Introduction: 54g Wireless LAN (WLAN) User Manual The 54g WLAN Solution Using the 54g WLAN Features and Requirements The 54g WLAN Solution The 54g WLAN solution accesses wireless local area networks (LANs), enables the sharing of a local printer and files with others in the network, accesses the Internet, and enables roaming about the officewire-free. This wireless LAN solution is designed for both the home user and small businessesand it is scalable so that users can be added and new network features can be enabled as networking needs grow. WEP is a security protocol for wireless local area networks (defined in IEEE Std 802.11, 1999 Edition) that encrypts data sent over radio waves. The use of the WEP key is optional and can be enabled or disabled. If the network being connecting to has enabled WEP, WEP must also be enabled in the network profile and the WEP key must be set to match the WEP key used by the network. Otherwise, it is impossible to connect to the network. Enterprise Users file:///P|/User%20Manuals/HP%20XP%20WLAN%20Card/intro.htm (1 of 3) [1/30/03 10:11:16 PM]
Introduction: Company 54g Wireless LAN (WLAN) User Manual Obtain the following information from the network administrator:
l Network names (SSID) of the specific wireless networks to connect to l WEP (Wired Equivalent Privacy) key information (if any) for the networks to connect to l For Microsoft Windows networking, the customer name and workgroup name l For a network account, a user name and password l An IP address (if not using a DHCP server) Using the Company 54g WLAN The 54g enabled device is an IEEE 802.11g based wireless LAN device. A LAN is composed of two or more computers that are connected to each other to share files or common equipment such as a printer or an Internet connection. A wireless LAN provides the same functionality of a wired network, but it eliminates the need to install networking cables and other networking equipment. Not only is a wireless LAN easier to deploy, but it also allows for roaming. Features and Requirements An IEEE 802.11 based wireless LAN includes the following features:
l Support for IEEE 802.11g draft specification l Support for IEEE 802.11b standard l 2.4-GHz band operation l Network data rate of up to 54 Mbit/s l Wired Equivalent Privacy (WEP) encryption The Company 54g enabled device works with any Wi-Fi CERTIFIED base station or wireless client adapter. file:///P|/User%20Manuals/HP%20XP%20WLAN%20Card/intro.htm (2 of 3) [1/30/03 10:11:16 PM]

Completing the Setup: Company 54g Wireless LAN (WLAN) User Manual Back to Contents Completing the Setup: Company 54g Wireless LAN (WLAN) User Manual NOTEBefore starting, obtain the required network information from the network administrator or the wireless access point installer (see The Company 54g WLAN Solution in Introduction). Modes of Operation Modes of Operation A wireless LAN can be configured for two different modes of operation: infrastructure network and computer-to-computer
(ad hoc) network. Whereas each mode has its advantages, one mode may be more appropriate than the other, depending on the location and type of network connection. Infrastructure Mode The key difference between the infrastructure type of network and an ad hoc network is that the infrastructure network includes a base station (host) computer that has a built-in wireless network adapter and is connected to a wireless access point (AP). This functionality allows computers on the infrastructure wireless LAN to access the resources and tools of the wired LAN, including Internet access, e-mail, file transfers, and printer sharing. Characteristics Networked computers communicate with each other through a dedicated AP. All data transmitted between the computers on this wireless LAN passes through the AP. Advantages l Extended range. The access point extends the range of the wireless LAN. Each computer can communicate with other computers equipped by wireless networks that are within the range of the access point. l Roaming. As the user moves around the home or office, the Company 54g enabled device determines the best access point to use to ensure continuous communication with the network. l Network connectivity. An access point can provide wireless LAN access to an existing wired network by bridging the two networks together. This gives users of the wireless LAN access to all the functions of a wired networkfrom file server access to e-mail and the Internet. Disadvantages Because the infrastructure mode offers more features, it requires additional components and setup time to deploy. file:///P|/User%20Manuals/HP%20XP%20WLAN%20Card/setup.htm (1 of 2 ) [1/30/03 10:11:18 PM]
Completing the Setup: Company 54g Wireless LAN (WLAN) User Manual Requirements A base station computer having a wired connection to the Internet, a wireless network adapter, and a connection to an AP. Computer-to-Computer Mode A peer-to-peer (ad hoc) network is the easiest to deploy and is ideal for home use or in small offices. This mode allows the sharing of files with other employees, printing to a shared office printer, and access to the Internet through a shared modem. With ad hoc networking, however, the computer is only able to communicate with other wireless networks that are within a certain range and are in the same wireless workgroup. Characteristics Networked computers send data directly to each other. Advantages l Simple setup l Cost efficiency Disadvantages Communication is limited to those who are located within a certain range. file:///P|/User%20Manuals/HP%20XP%20WLAN%20Card/setup.htm (2 of 2 ) [1/30/03 10:11:18 PM]

Copyright and Trademark Information Regulatory Statements for BCM94320P USA-Federal Communications Commission (FCC) This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy. If not installed and used in accordance with the instructions, it may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by tuning the equipment off and on, the user is encouraged to try and correct the interference by one or more of the following measures:
-Reorient or relocate the receiving antenna
-Increase the distance between the equipment and the receiver.
-Connect the equipment to outlet on a circuit different from that to which the receiver is connected.
