Wireless Local Area Networks (LANs) allow mobile computers to communicate wirelessly and send captured
data to a host device in real time. Before using the EDA on a WLAN, the facility must be set up with the
required hardware to run the wireless LAN and the EDA must be configured. Refer to the documentation
provided with the access points (APs) for instructions on setting up the hardware.
To configure the EDA, a set of wireless applications provide the tools to configure and test the wireless radio in
the EDA. The Wireless Application menu on the task tray provides the following wireless applications:
•

Single Country Use:
When the device is only used in a single country, set every profile country to Allow Any
Country. In the Options - Regulatory dialog box (see Figure 7-46 on page 7-35), select the
specific country the device is used in, and deselect the Enable 802.11d option. This is the
most common and efficient configuration, eliminating the initialization overhead
associated with acquiring a country via 802.11d.
Multiple Country Use:
When the device is used in more than one country, select the Enable 802.11d option in
the Options - Regulatory dialog box (see Figure 7-46 on page 7-35). This eliminates the
need for reprograming the country (in Options - Regulatory) each time you enter a new
country. However, this only works if the infrastructure (i.e., APs) supports 802.11d (some
infrastructures do not support 802.11d, including some Cisco APs). When the Enable
802.11d option is selected, the Options - Regulatory - Country setting is not used. For a
single profile that can be used in multiple countries, with infrastructure that supports
802.11d (including Symbol infrastructure), set the Profile Country to Allow Any Country.
Under Options - Regulatory, select Enable 802.11d. The Options - Regulatory - Country
setting is not used.
For a single profile that can be used in multiple countries, but with infrastructure that does
not support 802.11d, set the profile country to Allow Any Country, and de-select (uncheck)
Enable 802.11d. In this case, the Options - Regulatory - Country setting must always be
set to the country the device is currently in. This configuration option is the most efficient
and may be chosen for use with any infrastructure. However, the Options - Regulatory Country setting must be manually changed when a new country is entered.
Note that using a single profile in multiple countries implies that there is a common ESSID
to connect to in each country. This is less likely than having unique ESSIDs in each
country, this requires unique profiles for each country.
For additional efficiency when using multiple profiles that can be used in multiple
countries, the country setting for each profile can be set to a specific country. If the current
country (found via 802.11d or set by Options - Regulatory - Country when 802.11d is
disabled) does not match the country set in a given profile, then that profile is disabled.
This can make profile roaming occur faster. For example, if two profiles are created and
configured for Japan, and two more profiles are created and configured for USA, then
when in Japan only the first two profiles are active, and when in USA only the last two are
active. If they had all been configured for Allow Any Country, then all four would always
be active, making profile roaming less efficient.

MS CHAP v2
Microsoft Challenge Handshake Authentication Protocol version 2 (MS CHAP v2) is a
password-based, challenge-response, mutual authentication protocol that uses the
industry-standard Message Digest 4 (MD4) and Data Encryption Standard (DES)
algorithms to encrypt responses. The authenticating server challenges the access client
and the access client challenges the authenticating server. If either challenge is not
correctly answered, the connection is rejected. MS CHAP v2 was originally designed by
Microsoft as a PPP authentication protocol to provide better protection for dial-up and
virtual private network (VPN) connections. With Windows XP SP1, Windows XP SP2,
Windows Server 2003, and Windows 2000 SP4, MS CHAP v2 is also an EAP type.
TLS
EAP TLS is used during phase 2 of the authentication process. This method uses a user
certificate to authenticate.

Authentication
Description
Challenge Handshake Authentication Protocol (CHAP) is one of the two main
authentication protocols used to verify the user name and password for PPP Internet
connections. CHAP is more secure than PAP because it performs a three way
handshake during the initial link establishment between the home and remote
machines. It can also repeat the authentication anytime after the link is established.
MS CHAP
Microsoft Challenge Handshake Authentication Protocol (MS CHAP) is an
implementation of the CHAP protocol that Microsoft created to authenticate remote
Windows workstations. MS CHAP is identical to CHAP, except that MS CHAP is
based on the encryption and hashing algorithms used by Windows networks, and the
MS CHAP response to a challenge is in a format optimized for compatibility with
Windows operating systems.

MS CHAP v2
MS CHAP v2 is a password based, challenge response, mutual authentication
protocol that uses the industry standard Message Digest 4 (MD4) and Data
Encryption Standard (DES) algorithms to encrypt responses. The authenticating
server challenges the access client and the access client challenges the
authenticating server. If either challenge is not correctly answered, the connection is
rejected. MS CHAP v2 was originally designed by Microsoft as a PPP authentication
protocol to provide better protection for dial-up and virtual private network (VPN)
connections. With Windows XP SP1, Windows XP SP2, Windows Server 2003, and
Windows 2000 SP4, MS CHAP v2 is also an EAP type.
PAP
Password Authentication Protocol (PAP) has two variations: PAP and CHAP PAP. It
verifies a user name and password for PPP Internet connections, but it is not as
secure as CHAP, since it works only to establish the initial link. PAP is also more
vulnerable to attack because it sends authentication packets throughout the network.
Nevertheless, PAP is more commonly used than CHAP to log in to a remote host like
an Internet service provider.
MD5
Message Digest-5 (MD5) is an authentication algorithm developed by RSA. MD5
generates a 128-bit message digest using a 128-bit key, IPSec truncates the
message digest to 96 bits.

not cached, you are prompted to enter credentials. This option only applies when logged
in.
On Resume
Selecting this reauthenticates an authenticated user when a suspend/resume occurs.
Once reauthenticated, the user is prompted for credentials. If the user does not enter the
same credentials that were entered prior to the suspend/resume within three attempts, the
user is disconnected from the network. This option only applies when logged in.
At Time
Select this option to perform a local verification on an authenticated user at a specified
time. The time can be an absolute time or a relative time from the authentication, and
should be in at least 5 minute intervals. Once the time has passed, the user is prompted
for credentials. If the user does not enter the correct credentials within three attempts, the
user is disconnected from the network. This option only applies when logged in.
Entering credentials applies these credentials to a particular profile. Logging out clears all cached credentials.
Editing a profile clears all cached credentials for that profile.

The Network Username and Network Password fields are used as credentials
for the profile selected in the Wireless Profile field. Currently these fields are
limited to 159 characters.

The Mask Password checkbox determines whether the password field is
masked (i.e., displays only the '*' character) or unmasked (i.e., displays the
entered text). Check the box to unmask the password. Uncheck the box to mask
the password (the default).
Status Field
The status field displays status that is important to the login dialog. If the user
opens the dialog and needs to prompt for credentials for a particular profile at
this time, it can use the status field to let the user know that the network is held
up by the password dialog being open.
Tapping OK sends the credentials though WCS API. If there are no credentials entered, a dialog box displays
informing the user which field was not entered.
The Log Off button only displays when a user is already logged on. When the Log Off button is tapped, the
user is prompted with three options: Log Off, Switch Users, and Cancel. Switching users logs off the current
user and re-initialize the login dialog box to be displayed for when there is no user logged on. Logging off logs

dialog box displays.
When the user is logged off, the EDA only roams to profiles that do not require credentials or to profiles that
were created with the credentials entered into the profile
The Cancel button closes the dialog without logging into the network. If the login dialog was launched by the
wCS and not by the user, tapping Cancel first causes a message box to display a warning that the cancel
disables the current profile. If the user still chooses to cancel the login at this point, the profile is cancelled.
