Terminology

Throughout this document, the following terms are used:

• client a d apt er – Re fe rs to all thre e t yp es of ad ap t e rs

• PC card, LM card, or PCI client ada pter – Refers to only a specific adapter

• workstation (or station) – Refers to a computing device with an installed

client adap ter

Parts of the Client Adapter

The client adapter is composed of three major parts: a radio, a radio antenna, and
two L E Ds .

Parts of the Client Adapter

Radio

The client adapter contains a direct-sequence spread spectrum (DSSS) radio that
operates i n th e 2 .4 - G Hz li cen se -f r ee I n du st ri al S cientific M ed ica l ( I S M ) ba nd .
The radio transmits data over a half-duplex radio channel operating at up to 11
Mbps.

DSSS technology causes radio signals to be transmitted over a wide frequency
range, using multiple frequencies simul taneously. The benefi t of this technol ogy
is its a bi lit y to pro tec t the data transm iss i on f ro m interf er en ce. F or ex ample, if a
parti cular fre quency encounters noise or in terferenc e or both , enough redund anc y
is built into the signal on other frequencies that the client adapter usually will still
be successful in its transmission.

Parts of the Client Adapte r

Radio Ant enna

Chapter1 Product Overview

The type of antenna used depends on your client adapter:

• PC cards have an integrated, permanently attached diversity antenna. The

benefit of the diversity antenna system is improved coverage. The system
works by allowing the card to switch and sample between its two antenna
ports i n orde r to s elect t he opt im u m port f or re ce i ving da t a p ackets . A s a
result, the card has a better chance of maintaining the radio frequency (RF)
connection in areas of interference. The antenna is housed within the section
of the card that hangs out of the PC card slot when the card is installed.

• LM cards are shipped without an antenna; however, an antenna can be

conne cted thr ough the card ’s external connector. If a snap-on antenna is used,
it should be operated in diversity mode. Otherwise, the antenna mode used
should correspond to the antenna port to which the antenna is connected.

• PCI client adap te rs ar e s h ip p ed w it h a 2 - dB i d i pole antenn a t ha t attaches t o

the adapter’s antenna connector. However, other types of antennas may be
used. PCI client adapters can be operated through the right antenna port on ly.

the LED co d e s.

Securit y Features of the Clien t Adapter

The client adapter supports two principal security fe atures to protect y our data as

keys and Extensible Authentication Protocol (EAP) or LEAP (also referred to as
EAP - Cisco Wireless).

WEP Keys

Note Refe r to the Ci sco Aironet Wireless LAN Ad apte rs So ftwa re

WEP is an optional IEEE 802.11 feature that provides your client adapter and
other devices on yo ur wirel ess ne twork wi th dat a confi dentia lity e quiv alent to that
of a wired LAN. It in vol ves packe t-by -pa c ket da ta en cr yptio n by th e t rans mit ting

Each device within your wireless network is assigned up t o four enc r yption ke ys,

For the cl ient adap ter , W E P i s impleme nt ed through the client utilit ies . I n

This m ethod pr o vi de s au th en ti cat ion servi ce to client adap ters who s e h o s t

For Wi ndows 95, 98, NT, 2000, or Me or future Windows operating systems, the
Aironet Client U tility set up pr og r am , wh ich in s tal ls the client ut ilities, is used to
enable LEA P o r EA P. After LEAP o r EA P is en ab led a nd t he co mp ut er is
rebooted , th e client ad ap ter auth en ti cat es to the R A D IUS server us in g th e

For Windows CE, Linux, and MacOS 9.x, LEAP is enabled through a particular

used by the client adapter to authenticate to the RADIUS server. In Windows CE,
you do not need to re-enter your username and password after your device is

In order to comply with FCC RF exposure limits, dipole antennas should
be located at a minimum distance of 7.9 inches (20 cm) or more from the
body of all persons.

–

High-gain, wall-mount, or mast-mount antennas are designed to be

Warnin g

Do not operate your wireless network device near unshielded
blasting caps or in an explosive environment unless the device has
been modified to be especially qualified for such use.

In order to comply with RF exposure limits established in the ANSI

card client adapter that the adapter’s integrated antenna is
positioned more than 2 inches (5 cm) from y our body or nearby
persons during extended p eriods of trans mitting or operating tim e.
If the antenna is positioned less than 2 inches (5 cm ) from the user,
it is recommended that the user limit exposure time.

EAP-enabled RADIUS server is running on your network. If your computer
is not using an operating system with built-in EAP support, this option is not
available. After EAP is enabled and your computer is rebooted, your client
adapter authenticates to the RADIUS server using your network logon and
receives a session-based WEP key.

Missing Fil es in Windows CE

If you experience a problem after attempting to install the driver for Windows CE,
some necessary files may be missing.

• If you ar e usi ng W ind ows CE 2.11, locate the m fcce 21 1 .d ll , arp. d ll, dh cp .dll ,

ndis.dll, and network.cpl files on the Windows CE Services CD that was
shipped with your Windows CE device or obtain them from the device
manufacturer. Then use Windows Explorer to copy these files into the
\Windows directory of the Windows CE device and reinstall the driver
follo w in g t h e i ns t ru ct io ns in th e “Installing the Driver for Windows CE”
section on page 3-18.

• If you are using Windows CE 3.00, obtain the mfcce300.dll file from the

devi ce manu factur er, us e Windows Explorer to c o py it int o th e \ Wind ows
directory of the Windows CE device, and reinstall the driver following the
instructions in the “Installing the Driver for Windows CE” section on
page 3-18.

Resolving Resource Conflicts

If you encounter problems while installing your client adapter on a computer
running a Windows operating system, you may need to specify a different
interrupt request (IRQ) or I/O range for the adapter.

The default IRQ for the client adapter is IRQ 10, which may not work for all
systems. Follow the steps for your specific operating system to obtain an available
IRQ .

Problems Associating to the Access Point

Follow the instructions below if your client adapter fails to associate to the Access
Point.

• If possible, move your workstation a few feet closer to the Access Point and

try again.

• Make sure the client adapter is securely inserted in your computer’s PC card

slot or PCI ex pa nsi on sl ot.

• If you ar e u sin g a P C I cl ien t ad ap ter , m ak e su r e t he an tenna is s e cu re ly

• Purchase a 128-bit cl ien t ad ap ter . Th is i s th e most se cur e op ti o n.

• Disable WEP for the client adapter and configure the adapter and the Access

Point to associate to mixed cells. This option presents a security risk because
your data is not encrypted as it is sent over the RF network.
