The 11Mbps Wireless PCMCIA Adapter now has a new,
higher-powered antenna that provides a greater range than
ever. The increased sensitivity helps filter out interference to
keep your signal clear. Improved error correction in the chipset
keeps you operating at higher transmission rates for longer
distances. Since you only need one Type II or III PCMCIA slot,
you're free to use your other slots for additional accessories.
The PCMCIA Adapter is a Plug-and-Play device that runs on
Windows 98/ME/2000/XP. It will automatically recognize the
wireless PCMCIA Adapter and initiate the installation process.
Upon successful installation, the wireless PCMCIAAdapter will
communicate seamlessly with other wireless home and office
networking products.
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. This wireless networking solution has been
designed for both large and small businesses, and it is scalable
so that you can easily add more users and new network
features as your business grows.
This manual will assist you in the installation of the Wireless
PCMCIAAdapter.

Network Configuration and
Planning
The WLANs supports legacy Ethernet LAN network configuration options
as defined by the IEEE802.11b standards committee.
The WLAN Card can be configured as:
Ad-Hoc for departmental SOHO LANs.
Infrastructure for enterprise LANs.
LAN-Interconnection for point-to-point link as campus backbone.

Wireless LAN Basic
Fig 2-1 Ad-Hoc Wireless LAN
An Ad-Hoc wireless LAN is a group of computers, each equipped with one
WLAN adapter, connected as an independent wireless LAN. Computers in
a specific Ad-Hoc wireless LAN must be configured to share the same radio
channel. (Fig 2-1)

GigaFast Ethernet
Section 2
Fig 2-2 Infrastructure Wireless LAN
The adapter provides access to a wired LAN for wireless workstations. An
integrated wireless and wired LAN is called an infrastructure configuration.
A group of WLAN PC users and an Access Point compose a Basic Service
Set (BSS). Each WLAN PC in a BSS can talk to any computer in the wired
LAN infrastructure via theAccess Point (Fig 2-2)
An infrastructure configuration extends the accessibility of a WLAN
equipped PC to a wired LAN, and doubles the effective wireless
transmission range for 2 WLAN PCs. Since the Access Point is able to
forward data within its BSS, the effective transmission range in an
infrastructure LAN is doubled. (Fig 2-3)
Fig 2-3 The effective transmission range

GigaFast Ethernet
Section 2
The use of a unique ID in a BSS is essential. All WLAN equipped PCs
configured without roaming options in independent BSS must be
configured with a BSS ID corresponding to the Access Point used in the
BSS. Check your Access Point for its BSS ID or use the Access Point
Browser Utility program to determine the BSS ID. (Fig 2-4)
The infrastructure wireless LAN configuration is appropriate for enterprise-
scale wireless access to a central database, or as a wireless application for
mobile users.
Fig 2-4 Roaming in an Extended Service Set (ESS)
Infrastructure mode also supports roaming capabilities for mobile users.
More than one BSS can be configured as an Extended Service Set (ESS).
The continuous network allows users to roam freely within an ESS. All
WLAN PCs and Access Point within one ESS must be configured with the
same ESS ID.
Before enabling an ESS with roaming capability, it is recommended to
select a feasible radio channel and optimum Access Point position. Proper
Access Point positioning combined with a clear radio signal will greatly
enhance performance.

Before installing your card, insert the Auto-Install CD into your CD-ROM
drive. Unless you have deactivated the auto-run feature of Windows, the
screen shown in Fig 3-1 should appear automatically.
If this screen doesn't appear automatically, you can access the installation
by clicking the Start button and choosing Run. In the drop-down box
provided type D:\Setup.exe (where D: is the letter of your CD-ROM drive).
Alternately, double-click My Computer, double-click the CD-ROM drive,
then double-click Setup.exe.

3. The setup will ask you for Custom or Typical installation. (Fig 3-4)
4. If “Custom” is chosen, you can select packages individually. If you
choose “Typical”, the 3 packages will be installed in your system. (Fig 3-
5)
The 3 packages are the Application, the PCMCIA card driver, and the USB
adapter driver. (Fig 3-6)
