communicate with wireless devices from other manufacturers that
conform to the same specifications.
• Spectrum24 products allow mobile devices to roam throughout large
facilities while remaining connected to the network.
• Spectrum24 antenna diversity allows adapters to alternate between
antennas with the best reception, increasing overall performance.
• Spectrum24 products allow the establishment of ad-hoc wireless
workgroup networks.
• Spectrum24 products are protocol-independent, allowing mobile devices
to communicate with a wide range of servers, hosts and systems.
Introduction

About the Spectrum24 Wireless LAN Adapter
4 Spectrum24 Wireless LAN Adapter Users Guide
2.1 Operating Modes
The Symbol Mobile Companion utility installs with the Spectrum24 Windows
driver. Use Mobile Companion to select the operational mode, ESSID,
encryption algorithm and power consumption mode used with the
Spectrum24 adapter.
Spectrum24 LA-4121 PC Cards and LA-4123 PCI adapters support the
following operational modes:
•In Infrastructure mode, the adapter interoperates with an access point
(AP). The adapter can roam freely between access point cells in the
network or transmit and receive across subnets. Mobile Units (MUs)
appear as network nodes to other devices in the network. Infrastructure
is the adapter default mode.
• Select Ad Hoc mode to form peer-to-peer networks without access
points. Use Ad Hoc to create networks where needed within established
Spectrum24 network coverage areas. The MU starting the Ad Hoc
network (the first Spectrum24 adapter transmitting a beacon) determines
the channel and data rate used for the other Spectrum24 adapters within
the network using the same ESSID.
About the Spectrum24 Wireless LAN Adapter
Spectrum24 Wireless LAN Adapter Users Guide 5
2.2 11 Mbps Operation
The Spectrum24 Wireless LAN adapter supports a maximum 11Mbps data
rate. The adapter automatically shifts to a 5.5, 2 or 1Mbps data rate when
unable to maintain a high quality connection at 11Mbps. When the WLAN
adapter detects improved signal strength, it shifts to an increased data rate,
up to the maximum 11Mbps.
The following factors can dynamically alter the data rate:
• signal strength between the access point and Spectrum24 adapter
• the ratio of good transmitted packets to attempted transmitted packets
that fall below a threshold
• the MU finds a higher transmit rate with another AP.
Physical obstructions and numerous devices operating in close proximity to
one another negatively impact the ability to maintain an 11Mbps access
point association.
About the Spectrum24 Wireless LAN Adapter
6 Spectrum24 Wireless LAN Adapter Users Guide
2.3 Power Management
LA-4121 PC Cards support the Continuously Aware (CAM) and Power Save
Polling (PSP) power-management modes. CAM requires the radio to remain
on. Symbol does not recommend CAM for battery powered devices.
The PCI version of the Spectrum24 WLAN adapter (model LA-4123)
functions in CAM only.
PSP mode allows the PC Card to conserve power by suspending
communication for short periods of time while still associated with an AP.
The AP saves data for transmission to the PC Card when it wakes at given
intervals. When the PC Card wakes to check for data, it switches back into
CAM until it is ready to suspend communications again.
The PSP performance index, which varies from Excellent to Acceptable,
allows users to specify how often the PC Card wakes to check for data.
The Excellent PSP performance index provides the quickest response time
(shortest sleep interval), while the Adequate PSP performance index provides
efficient power consumption (longest sleep interval). Use the Adequate
performance index when periods of PC Card inactivity are anticipated or
when using a battery for a notebook computer.
Use the Symbol Mobile Companion Power Property Page utility to manually
set the PSP performance index.
2.4 Plug and Play
The PCI version of the Spectrum24 WLAN adapter (model LA-4123) supports
Plug and Play systems. This allows a computer to recognize the PCI adapter,
and configure the hardware interrupt, memory and device recognition
addresses. This feature requires less user interaction and minimizes
hardware conflicts.

A.4.3 Encryption Property Page
Use the Encryption property page to set the adapter profile security level.
The firmware supports Open System (no encryption), 40-bit Shared Key
(40-bit), 128-bit Shared Key (128-bit) and Kerberos encryption algorithms.
The absence of a physical connection makes wireless links vulnerable to
information theft. Encryption is an efficient method of preventing data theft
and improving data security.
The access point and the adapter are required to use the same encryption
algorithm to associate and transmit data. If an access point is set to Open
System and an adapter is set to 40-bit or 128-bit, no association takes place.
Similarly, if an adapter is set to Open System and an access point is set to
40-bit or 128-bit, no association takes place.
If an access point is set to 40-bit and an adapter is set to 128-bit the adapter
can associate to the access point, but no data transmission can take place.
Using the Mobile Companion Utility
Spectrum24 Wireless LAN Adapter Users Guide A - 9
Choose one of the following Encryption options from the Algorithm
pull-down menu:
•Open Systems (no encryption) - Use the Open System option as the
default setting when no data packet encryption is needed over the
network. Selecting Open System provides no security for the data being
transmitted over the network.
•40-bit Shared Key - Select 40-bit encryption and enter a 10 Hex digit
(0-1, A-F) encryption key. Use the Reset Keys button to set the encryption
key to the default values.
•128-bit Shared Key - Select 128-bit encryption and enter a 26 Hex digit
(0-1, A-F) encryption key. The 128-bit encryption option provides a
higher level of security than 40-bit encryption while maintaining an 11
Mbps data rate. Use the Reset Keys button to set the encryption key to
the default values.
The default Hex digit keys are visible any time they are used. As a security
precaution after setting the key values for the network, the digits are replaced
with asterisks *
**
* within the Encryption key fields.
If the associated AP is using a Passkey, the "active" adapter profile is required
to use the same string. The Passkey is a plain text representation of the
WEP keys displayed in the Encryption property page. The Passkey provides an
easy way to enter WEP key data without having to remember the entire 40-bit
(10 character) or 128-bit (26 character) Hex digit string. The Passkey is
case sensitive.
Click the Passkey button to display the Passkey screen. Enter an
easy-to-remember 4 to 32 character string to be used as the WEP algorithm.
Click OK. The MU transforms the Passkey string into a set of four WEP keys
using MD5 algorithms and displays them in the WEP fields. These are the
new WEP keys for the adapter profile. Once displayed in the WEP key fields,
the adapter profile behaves as if the keys were entered manually.

Configuring Kerberos for the Adapter
Kerberos is a different form of 128-bit data security whereby an adapter is
required to have its request for access point resources authenticated with a
Kerberos server before the server permits the access point to transmit and
receive data with the associated adapter.
Select Kerberos and enter the name of the server that hosts the Kerberos
KDC in the Realm field. The KDC is located on a server and maintains
information about the access points and users it supports. The KDC also
permits the transmission and receipt of data once the credentials of the user
are verified. The KDC field should remain blank unless the default KDC
name (krbtgt) is different on the server. Click OK to save the changes.
Changing the KDC in Mobile Companion displays an error message stating
the adapter has failed to authenticate. Only System and Network
Administrators should alter the KDC values of the access point and adapter.

E.4.3 Encryption Property Page
Use the Encryption property page to set the adapter profile security level.
The firmware supports Open System (no encryption), 40-bit Shared Key
(40-bit), 128-bit Shared Key (128-bit,) Kerberos and EAP-TLS encryption
algorithms. The absence of a physical connection makes wireless links
vulnerable to information theft. Encryption is an efficient method of
preventing data theft and improving data security.
The access point and the adapter are required to use the same encryption
algorithm to associate and transmit data. If an access point is set to Open
System and an adapter is set to 40-bit or 128-bit, no association takes place.
Similarly, if an adapter is set to Open System and an access point is set to
40-bit or 128-bit, no association takes place. For information on configuring
the Spectrum24 access point for milt-ESS MU support (VLAN), refer to the
AP-4131 Access Point Product Reference Guide available from the Symbol
Web site.
If an access point is set to 40-bit and an adapter is set to 128-bit the adapter
can associate to the access point, but no data transmission and reception
can take place.
Using the Mobile Companion Utility in Windows CE
Spectrum24 Wireless LAN Adapter Users Guide E - 9
Choose one of the following Encryption options from the Algorithm
pull-down menu:
•Open Systems (no encryption) - Use the Open System option as the
default setting when no data packet encryption is needed over the
network. Selecting Open System provides no security for the data being
transmitted over the network.
•40-bit Shared Key - Select 40-bit encryption and enter a 10 Hex digit
(0-9, A-F) encryption key. Use the Reset Keys button to set the encryption
key to the default values.
•128-bit Shared Key - Select 128-bit encryption and enter a 26 Hex digit
(0-9, A-F) encryption key. The 128-bit encryption option provides a
higher level of security than 40-bit encryption while maintaining an 11
Mbps data rate. Use the Reset Keys button to set the encryption key to
the default values.
The default Hex digit keys are visible any time they are used. As a security
precaution after setting the key values for the network, the digits are replaced
with asterisks *
**
* within the Encryption key fields.
If the associated AP is using an optional Passkey, the "active" adapter profile
is required to use one as well. The Passkey is a plain text representation of
the WEP keys displayed in the Encryption property page. The Passkey
provides an easy way to enter WEP key data without having to remember the
entire 40-bit (10 character) or 128-bit (26 character) Hex digit string.

Spectrum24 Wireless LAN Adapter Users Guide E - 11
Configuring Kerberos for the Adapter
Kerberos is a different form of 128-bit data security whereby an adapter is
required to have its request for access point resources authenticated with a
Kerberos server before the server permits the access point to transmit and
receive data with the associated adapter.
Select Kerberos and enter the name of the server that hosts the Kerberos
KDC in the Realm field. The KDC is located on a server and maintains
information about the access points and users it supports. The KDC also
permits the transmission and receipt of data once the credentials of the user
are verified. The KDC field should remain blank unless the default KDC
name (krbtgt) is being changed in the access point.
Changing the KDC in Mobile Companion displays an error message stating
the adapter has failed to authenticate. Only System and Network
Administrators should alter the KDC values of the access point and adapter.

E - 12 Spectrum24 Wireless LAN Adapter Users Guide
Configuring EAP-TLS for the Adapter
The Extensible Authentication Protocol-Transport Level Security (EAP) feature
affords access points and their associated MU’s an additional measure of
security for data transmitted over the Spectrum24 wireless network. Using
EAP, authentication between devices is achieved through the exchange and
verification of certificates. EAP can be used in mixed mode security support
with Kerberos and WEP. EAP is a mutual authentication method whereby both
the MU and access point are required to prove their identities. Like Kerberos,
the user loses device authentication if the server cannot provide proof of
device identification. To enable EAP-TLS support:
If problems are encountered during the EAP-TLS certification process for the
handheld computer, refer to the EAP server administrator for troubleshooting
information. Ensure an Active Sync connection exists between the handheld
computer and the root certificate EAP-TLS authentication server.

E.4.7 Signal Property Page
Select Signal from the Mobile Companion Status menu to display the Signal
property page.
Use the Signal property page to display a real-time graph of the signal
quality of the adapter to the associated access point. The number of times
the adapter has roamed to and from access points, the MAC Address of the
associated AP (located on the bottom of the access point), the current data
rate and the network status are displayed. Signal quality is an indicator of
how clearly the adapter can hear the associated access point.
The Missed Beacons graph displays the amount of beacons (uniform system
packets broadcast by the access point to keep the network synchronized)
missed by the receiving adapter. The fewer the missed beacons the better the
signal. As long as the LED to the right of the graph is Green the access point
association is not jeopardized by an excess of missed access point beacons.
If the LED is Red, an association with a different access point could be
warranted to reduce the amount of missed beacons and improve the signal.

The Txmit Retries (Transmit Retries) graph displays the number of data
packets retransmitted by the adapter. The fewer transmit retries the stronger
the signal. As long as the LED to the right of the graph is Green the access
point association is not jeopardized. If the LED is Red, an association with a
different access point could be warranted to reduce the amount of transmit
retries and improve the signal.
The Signal graph displays the RSSI (Relative Signal Strength Indicator) of the
signal transmitted between the access point and adapter. As long as the LED
to the right of the graph is Green the access point association is not
jeopardized. If the LED is Red, an association with a different access point
could be warranted to improve the signal.
The Signal property page is view only and is not available if the current
operating mode is Ad Hoc.

•IP Address
IP AddressIP Address
IP Address - The Internet is a collection of networks with users that
communicate with each other. Each communication carries the address
(IP address) of the source and destination networks and the particular
machine within the network associated with the user or host computer at
each end. Each node on the IP network must be assigned a unique IP
address that is made up of a network identifier and a host identifier.
Enter the IP address as a dotted-decimal notation with the decimal value
of each octet separated by a period, for example, 192.168.7.27.
•Subnet Mask
Subnet MaskSubnet Mask
Subnet Mask - Most TCP/IP networks use subnets in order to effectively
manage routed IP addresses. Having an organization's network divided
into subnets allows it to be connected to the Internet with a single shared
network address.
•Gateway

DNS - The Domain Name System (DNS) is a distributed Internet directory
service. DNS is used mostly to translate domain names and IP addresses.
It is also used to control Internet email delivery. Most Internet service
requires DNS to operate properly. If DNS is not configured, Web sites
cannot be located or email delivery fails.
•WINS
