Introduction:
The 802.11g WLAN Solution
Using the 802.11g WLAN
The 802.11g WLAN Solution
The 802.11g 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 office—wire-free. This wireless
LAN solution is designed for both the home user and small businesses—and 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.

Introduction: Company 54g Wireless LAN (WLAN) User Manual
Obtain the following information from the network administrator:
● Network names (SSID) of the specific wireless networks to connect to
● WEP (Wired Equivalent Privacy) key information (if any) for the networks to connect to
● For Microsoft® Windows® networking, the customer name and workgroup name
● For a network account, a user name and password
● An IP address (if not using a DHCP server)
Features and Requirements
An IEEE 802.11 based wireless LAN includes the following features:
● Support for IEEE 802.11g draft specification
● Support for IEEE 802.11b standard
● 2.4-GHz band operation
● Network data rate of up to 54 Mbit/s
● Wired Equivalent Privacy (WEP) encryption
Using the 802.11g WLAN
The 802.11g 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.
The 802.11g enabled device works with any Wi-Fi CERTIFIED® base station or wireless client adapter.

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
Disadvantages
Because the infrastructure mode offers more features, it requires additional components and setup time to deploy.
Completing the Setup:
NOTE—Before starting, obtain the required network information from the network administrator or the wireless access
point installer (see The Company 802.11g WLAN Solution in Introduction).
● 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.
● Roaming. As the user moves around the home or office, the 802.11g enabled device determines the
best access point to use to ensure continuous communication with the network.
● 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
network—from file server access to e-mail and the Internet.

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
● Simple setup
● Cost efficiency
Disadvantages
Communication is limited to those who are located within a certain range.

●
Rate sets the transmission rate. The default setting is Use best rate. This automatically adjusts the data rate to
the optimal rate based on the capabilities of the other clients and access points.
The default values for the properties listed below are set for maximum performance. Therefore, It is not recommended for
home users to change the settings for any of these properties. Only network administrators or persons having technical
wireless LAN experience should attempt to change any of the settings.
● Fragmentation Threshold is the threshold at which the IEEE 802.11 adapter break the packet into multiple
frames.
● IBSS 54g (TM) Mode is used to set the connection type in an ad hoc network. The following options are
available:
❍ 54g - 802.11b compatible— links at the best rate with an IEEE 802.11b and an IEEE 802.11g network
(recommended setting).
❍ 54g - Performance— links only with IEEE 802.11g networks at the highest rate. In addition it excludes
IEEE 802.11b networks.
❍ 802.11b Mode— links only with IEEE 802.11b networks at the highest rate. In addition it excludes IEEE
802.11g networks.
● Locally Administered MAC Address is used to override the MAC address of the Company 54g Wireless LAN
adapter.
● PLCP Header is used to set the header type used for CCK rates. Can be long, auto (short/long).
● Power Output is used for putting out a percentage of the maximum output power.
● Power Save Mode is used to put the Company 54g enabled device into the IEEE 802.11 Power Save mode.
In Power Save mode, the radio is periodically powered down to conserve power. When in Power Save mode,
packets are stored in the AP until the STA comes on.

Regulatory Statements for RSVLD-0608
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.
-Consult the dealer or an experienced radio/TV technician for help.
Any changes or modifications not expressly approved by the party responsible for compliance
could void the user’s authority to operate the equipment.
Caution: Exposure to Radio Frequency Radiation.
To comply with FCC RF exposure compliance requirements, a separation distance of at least 20 cm must
