1Introduction
The advantages of a radio network (Wireless LAN) are obvious: notebooks and
PCs can be set up where they are needed. Due to Wireless LANs, problems
with missing connections or structural alterations belong to the past.
Network access in conferences or during presentations, access to resources in
neighbouring buildings or data exchange with portable terminals are only
some possible applications of Wireless LANs.
1.1 The AirLancer models
The AirLancer series with 54 Mbps data transfer rate features several models.
You have the possibilty to extend standard PCs and a multitude of mobile
computers for access to the Wireless LAN:
EN
왘 AirLancer MC-54ag
Dual band PC card (Cardbus) according either to IEEE 802.11a (up to 54
Mbps data tranfer rate in the 5 GHz band) or to IEEE 802.11g (up to 54
Mbps data transfer rate in 2,4 GHz, backward-compatible to IEEE
802.11b) for operation with mobile devices
왘 AirLancer PCI-54pro
Dual band PCI adapter according to IEEE 802.11a (up to 54 Mbps data
tranfer rate into 5 GHz frequency band) or IEEE 802.11g (up to 54 Mbps
data tranfer rate into 2,4 GHz frequency band, backward-compatible to
IEEE 802.11b) for installation in a stationary desktop PC. You find an
external dual band antenna enclosed with the product.
왘 AirLancer USB-54ag
Dual band USB adapter according to IEEE 802.11a (up to 54 Mbps data
tranfer rate into 5 GHz frequency band) or IEEE 802.11g (up to 54 Mbps
data tranfer rate into 2,4 GHz frequency band, backward-compatible to
IEEE 802.11b) for installation in a USB interface of stationary desktop PCs
or mobile devices.

AirLancer MC-54 – AirLancer USB-54 – AirLancer PCI-54
1.2 Encryption in three security steps
AirLancer 54 Mbps Wireless LAN adapters support three different variants of
encryption:
왘 WEP64, WEP128, WEP152 – for encryption in accordance with Wired
Equivalent Privacy (WEP), encryption keys are used with an effective
length of 40, 104 or 128 bit.
EN
왘 WPA – this method uses the encoding methods TKIP and Michael (only
Windows 2000 or XP)
왘 WPA2 – als Nachfolger von WPA is based on AES (Advanced Encryption
Standard) (only Windows 2000 or XP)
왘 802.11i – for the at present highest security standard the encoding
method AES (Advanced Encryption Standard) is used (only Windows 2000
and XP)
Further details to WLAN security and the used encoding methods can be
found in the LCOS reference manual.
Please inform yourself about the valid legal regulations for employment of encryption technology in the country you want to use a AirLancer Wireless LAN adapter. Pay attention to use no devices which
support inadmissible encryption technologies.
1.3 Default WEP encryption
The standard WEP key consists of the first letter “L” followed by the LAN MAC
address of the access point in ASCII characters. The LAN MAC addresses of the
LANCOM devices always begin with the character string “00A057”. You will
find the LAN MAC address on a sticker on the base of the device. Only use the
number labeled as “MAC address” that starts with “00A057”. The other numbers that may be found are not the LAN MAC address!
8
As of LCOS version 4.0, WEP128 encryption is activated for every
unconfigured access point as standard.
Page 9
AirLancer MC-54 – AirLancer USB-54 – AirLancer PCI-54
A device with the LAN MAC address “00A0570FB9BF” thus has a standard
WEP key of “L00A0570FB9BF”. This key is entered into the 'Private WEP settings' of the device for each logical WLAN network as 'Key 1'.
To use a WLAN adapter to establish a connection to a new LANCOM access
point, the WEP128 encryption must be activated for the WLAN adapter and
the standard 13-character WEP key entered.
Please notice that also the WLAN encryption settings of the access
point will get lost in case of a reset of the device and the standard
WEP key comes into effect again. The wireless communication with
the device will only succeed after a reset, if the standard WEP key is
programmed into the WLAN adapter!

2 Installation
In this chapter you will find a description of the AirLancer WLAN clients and
a step-by-step instruction for starting the devices. After installation of hardware, drivers and the AirLancer software, you have to set up the access to a
Wireless LAN. The description of this configuration step can be found for both
AirLancers in chapter 3.
EN
2.1 Properties
The AirLancer WLAN adapters are compliant to the IEEE 802.11a and IEEE
802.11g standards, and are thus excellent suitable for notebook users who
need a maximum of flexibility and performance. The switch between the radio
standards can be made as desired automatically, and enables at any time the
fastest possible connection. So for example the connection to a company network with up to 54 Mbps can be made with the IEEE 802.11g or IEEE 802.11a
standard, while on journeys the compatibility to public hot spots is ensured
with up to 11 Mbps transfer rate according to IEEE 802.11b.
2.1.1 AirLancer MC-54ag
The radio network card AirLancer MC-54ag is a PC card for notebooks and
mobile devices with Cardbus interface. It is a little bit longer than other PC

During the installation, a driver that supports all current AirLancer WLAN
adapters is installed on your system. A benefit of this is that switching between an AirLancer USB-54ag and an AirLancer MC-54ag, for example, does
not require a new driver to be installed. When the AirLancer card is started for
the first time, the driver is activated just once.
The integrated WLAN module in some Intel Centrino computers will
only operate simultaneously with an AirLancer card on the condition
that the Intel WLAN module connects to the remote before the
AirLancer card. To this end, the AirLancer card has to be set up for
manual registration.

3.3 Overview of the functions
Configuration of the AirLancer WLAN adapters is carried out in the AirLancer54 software with the aid of configuration profiles. Separate profiles can be
created for different adapters or wireless networks and activated accordingly.
3.3.1 Creating, modifying and removing of profiles
Creating profiles
To add a new configuration profile, click New on the 'Profile Management'
tab.
왘 For ad-hoc networks you have to enter network name, radio channel and
WEP key.
Ad-hoc networks are only possible in the 2,4 GHz frequency band
using IEEE 802.11g and IEEE 802.11b. Ad-hoc networks are not available with IEEE 802.11a in the 5 GHz band.
왘 When using base stations you can scan (open) Wireless LANs within
reach. The available radio networks within reach are listed on the register
card Profile Management under Scan. You can easily select the desired
one by cklicking on and activating it via Activate.
Modifying profiles
To modify a configuration profile, select the configuration from the Profile list
and click the Modify button.
EN
Removing profiles
Select the profile to remove from the list of configuration profiles on the 'Profile Management' tab and click the Remove button.
3.3.2 Profile Auto Selection
Including a profile in the auto selection feature allows the wireless adapter to
automatically select that profile from the list of profiles and use it to connect
to the network.
Note that the ACU only allows the creation of 16 configuration profiles.
21
Page 22

왘 Chapter 3: The AirLancer 54 software
To include a profile in auto profile selection click the Order Profiles button
on the 'Profile Management' tab. Highlight the profiles to add to auto profile
selection, then click Add. The profiles appear in the Auto Selected Profiles
box.
To order the auto selected profiles highlight a profile in the 'Auto Selected Profiles' box and click Move Up or Move Down as appropriate. The first profile
in the Auto Selected Profiles box has highest priority, and the last profile has
lowest priority.
EN
With auto profile selection enabled, the wireless adapter scans for available
networks. The highest priority profile with the same SSID as a found network
is used to connect to the network. On a failed connection, the client adapter
tries with the next highest priority profile.
3.3.3 Analysis, diagnosis and information
The page Current Status of your AirLancer 54 software lists information
about the status of the Wireless LAN and the your own radio LAN interface,
as well as the currently selected frequency band, the signal strength, the name
of the selected profile and your own IP address.
Information about sent and received data can be found under Diagnostics,
under the Advanced Statistics tab there are statistics and further information about transfered frames and potential transmission errors shown.
You may deactivate the radio connection uder Action 왘 Disable Radio,
change the country setting (Country Select) and disable the indication of the
tray icons (Disable Tray Icon).

support (den Teil versteh ich nicht)] can be found in the Help of the AirLancer
Link Monitor. To launch the AirLancer Link Monitor click on Start 왘 Pro-
grams 왘 LANCOM 왘 AirLancer Link Monitor.
3.3.4 Configuration with Windows XP configuration tools
For configuration of the AirLancer card under Windows XP, it is possible to use
the integrated configuration tools of Windows XP, as well as the AirLancer 54
software. In some situations it might be required to use Microsoft Zero Config,
for instance if a domain registration is necessary. When running the AirLancer
54 software under Windows XP, the integrated configuration software of the
operating system has to be deactivated in any case. To do so, open under Set-
tings 왘 Control Panel the Network connections. Click with your right

왘 Chapter 3: The AirLancer 54 software
mouse button on Wireless network connection and select Properties.
Deactivate the software on the index card Wireless networks..
When this check box is selected, Windows XP takes control of these settings
for all configuration profiles:
왘 SSID
왘 Security keys
왘 Ad hoc settings
Note that Windows XP takes control of these settings for all configuration
profiles, thus users can not (for example) create new profiles with different
settings while using Windows Zero Configuration.
The Zero Configuration settings override all configuration profiles, even when
you select other options. However, the ACU does still control the following
settings when Zero Configuration is set:
왘 Power settings
왘 Active/Passive scanning (where applicable)
왘 Transmit power
왘 Wireless band
왘 Short/Long preamble (802.11b)
EN
When Zero Configuration is in use, a pop-up message is displayed on the ACU
when you attempt to create or edit a configuration profile from the Profile
Management tab of the ACU.
3.4 Encryption settings
You have to enter the keys in the settings for encryption which should secure
the connection into the whole Wireless LAN.
3.4.1 802.11i und WPA
Only under Windows 2000 or Windows XP
All AirLancer 54 WLAN adapters use the Atheros chipset with a hardware AES
accelerator. Therefore the highest rate on encoding without loss of performance is guaranteed.
23
Page 24
AirLancer MC-54 – AirLancer USB-54 – AirLancer PCI-54
왘 Chapter 3: The AirLancer 54 software
With the user-friendly Pre-Shared-Key method (entering a passphrase of a
length of 8 to 63 signs) the use of 802.11i is easy for everyone. 802.1x and
RADIUS servers can be used in professional infrastructures with a large number of users.
3.4.2 WEP
General rules for WEP keys
EN
When using WEP keys, please pay particular attention to the following general
information:
왘 You have to use exactly matching keys between all involved devices. All
devices use a common key within ad-hoc-networks. In infrastructure networks, the key between base station and its radio stations must match .
왘 Different key lengths cannot be used simultaneously on a base station. In
order to giving users with WEP64 devices encrypted access to a base station, the encryption for this base station must be set to WEP64.
왘 Wireless LAN interfaces with WEP128 always contain also WEP64, too. At
the same time, WEP128 is downward compatible to WEP64. A WEP128
device will register automatically with the short key at a WEP64 encrypted
base station.
Rules for entering WEP keys
WEP keys can be entered as ASCII characters or in hexadecimal form. The
hexadecimal form begins with the characters '0x'. The keys have a length
depending on the WEP method:
Method ASCII HEX
WEP 64 5 characters
Example: 'aR45Z'
WEP 128 13 characters 26 characters
WEP 152 16 characters 32 characters
10 characters
Example: '0x0A5C1B6D8E'
The ASCII character set includes the characters '0' to'9', 'a' to 'z', 'A' to 'Z' and
the following special characters:
!”#$%&´()*+,-./ :;<=>?@[\]^_‘{|}~
The HEX form uses the numbers '0' to '9' and the letters 'A' to 'F' to display
each character as a character pair, which is why twice the number of
characters is required to display a HEX key.

왘 Chapter 3: The AirLancer 54 software
All kinds of special characters, e.g. special regional characters ('ä', 'ö',
'ü', 'ß') are no valid entries.
Numerous Wireless LAN devices of other manufacturers only accept hexadecimal values as WEP keys or may generate even special characters from arbitrary
passwords.
Therefore if may happen that that you cannot enter a WEP key into a device
of another manufacturer, which your AirLancer accepts without any problem.
In such a case it is advisable to use the key of the more inflexible device for
the connection.

This chapter exemplifies the use of AirLancer radio network cards with the
following example:
4.1 Connecting to a company network
The main advantage of radio networks beside the establishing of independent
EN
networks is the possibility to extend existing, cable-bound networks. It does
not matter whether the existing LAN has to be extended, the wiring of new
workstations is however uneconomic or impossible, or whether e.g. field sales
representatives need to be integrated mobilely for their office work time into
the corporate LAN.
Example: sales
departement
As example for an infrastructure network we look at the sales department of
a mid-sized company. The sales representatives will move to another floor.
Since they are out of the office most time anyway, their new workplaces are
not wired anymore. Instead, a Wireless LAN access point enables to access the
corporate Intranet services (e.g. LANCOM 3550 Wireless). Since the sales representatives with their notebooks must have access to the network also in
other departments of the company, further base stations will be installed.
These ensure that a sales representative has access to the network within the
company building at any time. When changing to another radio cell, the stations are disconnected automatically from the previous base station and connected to the new base station. This procedure is called roaming.
Each sales representative gets a radio network card
AirLancer MC-54g
for his
notebook, with which he is able to log into the network of the company in his
office. For also being able to print locally, the sales representatives have still
got a network printer in their office, which is attached to the cable-bound

To be able to join the WLAN base station and exchange data with the LAN,
the WLAN cards of the notebooks as well as the base stations must have the
matching settings in different parameters. To be able to make a first network
contact, you must specify only the network name.
EN
Defining a network name (SSID)
You must make this specification in any case. The network name must be
entered identically for all stations of the radio network. It is registered in the
AirLancer 54 software.
You have the possibility to store own profiles for different Wireless LANs in the
AirLancer 54 software.
If you use your notebook both in the office and at home, you could create two
profiles: a profile 'Work' for the office and a profile 'Home' for at home. If you
want to work in the evenings or during the weekend at home, then just switch
to the according profile.
Encryption of radio data
Activate the 802.11i/WPA or WEP encryption of your radio connection in the
AirLancer 54 software to secure the transmission over the radio link data so
that it cannot be read by others. Up to four different alphanumeric (5, 13 or
16 characters) or hexadecimal (10, 26 or 32 characters) keys are supported by
base stations in parallel.

Connections the properties of your AirLancer client adapter. Under 'Bin-
dings', the TCP/IP protocol should be selected in any case, whereas e.g. IPX/
SPX protocols are additionally needed in Novell networks only.
Information regarding configuration of base stations can be found in

the documentation of your LANCOM Wireless base station and in the
electronical documentation of your CD.
Access to LAN
After installing the radio network cards, all functions and services are available for the sales representatives with their notebooks, which were also offered to the desktop PCs in the cabel-bound network. Being part among others:

5 Extension of the LANCOM 3550 Wireless
base station
The WLAN base stations of the LANCOM 3550 Wireless series have numerous
possibilities of extension, especially the flexibility to use the extensive LANCOM accessories.
Due to a second, from outside accessible cardbus slot, it is possible to upgrade
base stations of the LANCOM 3550 Wireless series with a second radio card
of the LANCOM AirLancer series, and to extend it this way with a second radio
cell, for example with new radio standards.
EN
Dual band operation of two radio
cells
It is possible to install a second radio cell for extension of the wireless network
for parallel operation of different radio standards simply by inserting a AirLancer MC-54ag into the cardbus slot of a base station of the LANCOM 3550
Wireless series. For example, a single device can serve radio network clients
with different standards simultaneously then.

IEEE 802.11a
Please ensure that your LANCOM 3550 Wireless base station has got
an up-to-date firmware image to support AirLancer MC-54ag prior to
installing the AirLancer MC-54ag. The latest firmware version for your
LANCOM 3550 Wireless base station is available on the LANCOM
website www.lancom.de

Before installing the AirLancer MC-54ag onto your LANCOM 3550 Wireless
ensure to turn off the base station by pulling the power supply cable out of
the it. Remove now carefully the blind slide-in module of the external cardbus
slot. Slip-in now the AirLancer MC-54ag card into the cardbus slot and restart
your device by plugging the power supply cable in again.
