Chapter 1 About the PROXIM WLAN 802.11b/g
device
1-1 Introduction
The PROXIM WLAN 802.11b/g device allows you to access Wireless Local Area Networks
(WLANs),share a local printer and files with others in your network, access the Internet, and roam
about the office—wirelessly. This wireless Local Area Network solution is designed for both large
and small businesses, and it is scalable so that you can add users and new network features as your
networking needs grow.
The PROXIM WLAN 802.11b/g device is a 2.4Ghz WLAN technology that will operate with at a
maximum data rate of 11Mbps with 802.11b and maximum data rate of 54Mbps with 802.11g
wireless networks.ThePROXIM WLAN 802.11b/g device will automatically detect and
seamlessly roam between both 802.11b and 802.11g wireless networks.
1-2 Using a Wireless Local Area Network
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 LANeasier to
deploy, but it also allows for mobility through “roaming.”For example the PROXIM WLAN
802.11b/g device can roam from a conference room to an office without being disconnected from
the network.

1-3 Features and Requirements
The PROXIM WLAN 802.11b/g device includes the following features:
Wireless Features
•Support for the IEEE 802.11bstandard
•Support for the IEEE 802.11g standard
•Operates within the 2.4-GHz band
•Maximum data rate of up to 11 Mbps (802.11b)
•Maximum data rate of up to 54 Mbps (802.11g)
Interoperability
•WiFi certified at 2.4GHz to ensure wireless interoperability with other WiFi (802.11b)
certified devices.

•Wired Equivalent Privacy (WEP) encryption, operating with 64bit, 128bit or 152 bit
encryption
•AES-CCM Encryption support
•Support for Windows 802.1X supplicants

Chapter 2 Network Configuring and Planning
A wireless LAN can be configured for twodifferent modes of operation. While each method has its
advantages, one may be better suited for your needs. Review the following configurations to
determine which mode is best for you.
•Ad-Hoc Network
•Access Point (Infrastructure)Network
2-1 Ad-Hoc Network
AnAd-Hoc network is the simplest to deploy and is ideal for small offices. Ad-Hoc wireless
networks can be comprised of two or more wirelessclient configured to communicate with one
another. All Ad-hoc clients communicate directly with each other without using an access point
(AP). As a user on this type of network, you are able to quickly build up a wireless network in order
to share files with other employees, print to a sharedoffice printer, and access the Internet through
a single shared connection.
Ad-hoc networking is cost effective, because no other devices components are needed (access
points, hubs or routers) in order to setup a network. However, with peer-to-peer Ad-Hoc
networking, your computer is only able to communicate with other nearbywireless clients.
Characteristics
Networked computers send data directly to each other
Advantages
•Simple setup
•Cost efficiency
Disadvantages
Communication is limited to nearby wireless clients
Figure 2-1

2-2 Access Point (Infrastructure) Network
AnAccess Point network is also referred to as an “Infrastructure” network. The key difference
betweena wireless access point network and anAd-Hoc network is the addition of one extra
element—the Access Point. The Access Point serves as the focal point for all data traffic on your
wireless network, optimally managing all wireless data transactions.
Additionally, the wireless Infrastructure can provide access to an existing wired LAN. This link
allows computers on the infrastructure wireless LAN to access the other wired LAN’s resources
and tools, including Internet access, email delivery, file transfer, and printer sharing.
Characteristics
Networked computers communicate with each other through a dedicated AccessPoint. All
data transmitted between the computers on this wireless LAN passes through the access point.
Advantages
•Extended range: The access point extends the range of the wireless LAN. Each wireless
client computer can communicate with other computers equipped with wireless devices
that are within the range of the access point.
•Roaming: As you move throughout the building, the PROXIM WLAN 802.11b/g device
will automatically search for an access point to use, ensuring continuous communication
with the wireless 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 corporate email, Internet,shared printers and files.
Disadvantages
Because this network mode offers more features, it requires additional components and setup
time to deploy.
