Preface
Thank you for placing yourtrust in this product.
Wirelessnetworksare economical alternativesor additionsto
local wired networks (LANs). Notebooks and PCs can use mobile network
cards to communicate with one another or access wired networks via access
points and canevenbe integrated into the ISDN network.
Thisdocumentation isintended for the user of theAirLancer MC-11,
AirLancer USB-11 andAirLancer PCI-11 mobilenetworkcards.
First we describe the devices and their options, then provide instructions for
installingthedevicesandthedriversandasaninitialapplicationexamplewe
describe how to connect two computers with each other and to an access
point.

1 Introduction
The advantages of wireless networks (wireless LANs) are obvious:
Notebooks and PCs can be set up where they are wanted. Problems with
missingports orconstructionalterationsareathingofthepastwithwireless
networking.
Network links in conferences or presentations, access to resources in
adjacent buildings and exchanging data with mobile units are only a few of
the options available with a wireless LAN.
1.1 What is a wireless LAN?
WirelessLANsconnectseparateunits(PCsandnotebooks)toalocalnetwork
(also LAN –LocalArea Network). Unlike conventional LANs, the connection
is established through radio transmission, not via a network cable. For this
reason, wireless LANs are also called Wireless Local Area Networks
(WLAN).
All of the standard functions of a wired network are also available in a
wireless LAN: Access to files, servers, printers etc. is possible as is the
integration of the single stations into an internal company e-mail system or
access to the Internet.
1.2 What is required for a wireless LAN?
The question of the required hardware arises in conjunction with the
advantages of awireless LAN.
1.2.1 Radio interfaces with the network
Every unit in the wireless LAN needs access to the wireless LAN in the form
ofaradiointerface.Devicesthatdonotcomewithastandardradiointerface,
can be upgraded using an advanced card oranadapter. You use an
AirLancer to upgrade your unit to access the wireless LAN.

then communicate directly via radio.

1.2.2 The center—the access point
The convenience and performance of a wireless LAN can enhanced with an
additionalaccess point.This access point permits thecentral administration
of the wireless LAN. In addition, the access point can be used to link the
wireless LAN to a cable-based LAN or to the Internet.
Depending on whether or not an access point is used, there are two possible
waystooperatethewirelessLAN:Eitherasanadhocnetwork(peer-to-peer),
or an infrastructure network (access point).
1.3 Operating modes
Let's havea look at both operating modes.
1.3.1 The ad hoc network
Inthecaseoftheadhocnetwork,twoormorecomputersthateachhavetheir
own interfaces to the wireless LAN are connected to one another. All
computers in a WLAN can then communicate with one another with no
additional hardware.
Ad hoc network This mode is also generally referred to as a peer-to-peer network
(spontaneous network). PCs can connect to each other immediately and
exchange data.
1.3.2 The infrastructure network
An access point is required to connect to an existing network. The access

offers access to a cable-based LAN or tothe ISDN and Internet.

Infrastructure
network A wireless LAN with one or more access points is generally referred to as a
peer-to-LAN network; however, in the LAN terminology this type of
networking isreferred to asan infrastructure network.accesspoints
also have an integrated router for ISDN or DSL connections. This allows all
connected stations to access the Internet.
This network type is ideally suited as an addition to existing LANs. The
infrastructure network is the ideal solution for expansion of a LAN in areas
where wiring is not possible or noteconomical.
1.4 IEEE 802.11b radio transmission
IEEE 802.11b All AirLanceroperateunder IEEE Standard 802.11b. This standard is a
supplement to the current IEEE standards for LANs, with IEEE 802.3 for
Ethernet being the most well-known. IEEE 802.11b covers the operation of
local wireless LANs on private and public property in the ISM frequency
range (Industrial, Scientific, Medical: 2.4 and 2.483 GHz).
Please note that not all frequencies are permitted in every country! A table
withthefrequenciesandtheapprovalregulationsisincludedintheappendix.
11 Mbps The maximum bandwidth for data transfer is 11 Mbps. However, the actual
throughput depends on both the distance and the quality of the connection.
Increasing distance and decreasing connection quality reduces the transfer
speed to 5.5 Mbps, then to 2 and finally 1 Mbps. The transfer range in the
open is up to 400 meters, in buildings it is typically around 30 –40 meters.
The actual range achieved strongly depends on the spatial environment.
Interferenceand obstacles in particular have a strong influence on the range.
Optimum positioning of the wireless stations is often decisive.

DSSS The wirelessLANcardsfrom usethe DSSSprocess(DirectSequence
Spread Spectrum) to shield against interference from other transmitters that
may be using the same frequency range. A transmitter normally uses only a
very narrow range of the available frequency band for transfer. If precisely
this range is also in use by another transmitter, this will cause interference
in thetransfer. In the DSSS processthetransmitteruses abroader sectionof
the possible frequency band and so is less sensitive to narrow-band
interference. This process isalso used by the military to make eavesdropping
more difficult.
1.5 The three AirLancers
The AirLancerseriesoffersyouthreemodels.Thisway,you can obtain
accesstothewirelessLANwithconventionalPCsandavarietyofnotebooks:

AirLancer MC-11 cardisdelivered withtheproduct.
1.5.1 Matching versions for international use
In the ISMrange, up to 13radio channels can beused. Some countries have
only released 11 out of 13 channels for public use. This is why there are two
versions of everywirelessLAN adapter:
TheEUversioncanbeusedintheentireEUandinmostoftheassociated
European countries. The card supports 13 radio channels and meets the
European CE standard.

|Introduction 13
|
AirLancer

The WORLD version is meant for use in Europe and other countries,
especially the USA. Apart from the European CE standard, it also meets
the American FCC standard. The maximum number of channels is 11.
Accessing an EU access point with an AirLancer WORLD version
In order to be able to access an EU access point (supports 13 radio channels)
with an AirLancerWORLDversion(onlysupports11radiochannels),youmust
choose a channel between 1 and 11 on the access point.
For guidance regarding the manual setting of channels please refer to the
documentation ofyour access point. A list of the radio channels that are sup-
ported by the two versions is available in paragraph 9.2 'Radio channels' on
page 54.
1.5.2 Encryption in two levels of security
Some countries regulate the use of encryption technology. This is why there
are two versions of everyAirLancerwireless LAN adapter:
WEP64—fortheencryption according to WiredEquivalentPrivacy(WEP)
keys are used with aneffectivelength of 40 bits.
WEP128—this model version uses keys with a length of 104 bits. The
encryption attained is considerably stronger, compared to the models
using WEP64.
Please inform yourself on the current legal regulations for the use of
encryption technology in the countrywhere you want touseanAAirLancer.Makesure not to use devic e s that support illegal encryption's
techniques.

Secure power supply
Ifduring the installation,the firmware of your AirLancerMC-11
turns out not to be up to date, the setup program will suggest to you the
automaticupdatingofthefirmware.Thisactionneedsyourconfirmation.
Please ensure before beginning with the updating of the firmware that a
stabile power supplyis guaranteed during the installation. Avoid carrying
out the installation on a notebook running on its battery. Please also
ensure that your computer does not shut down or go into standby during
the updating process. Close allapplicationsbefore starting.
Additional system requirements for Windows NT 4.0
For the installation under Windows NT 4.0 please ensure that the
required system resources are available before placing the card into your
computer. The procedure is as follows:
The AirLancerMC-11will be installed withIRQ10 and theaddress
range '400–437'by default. The interrupts andaddresses can be viewed
under Start Programs Administrative Tools (Common) 
