Chapter 7Wireless ApplicationsChapter 7Chapter 7 Wireless ApplicationsIntroductionWireless 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:•Wireless Status•Wireless Diagnostics•Find WLANs•Manage Profiles•Options•Enable/Disable Radio•Log On/Off.Tap the Signal Strength icon to display the Wireless Applications menu.

The Operating Mode dialog box displays.Operating ModeUse the Operating Mode dialog box to select the operating mode (Infrastructure or Ad-Hoc) and the country location. Figure 7-6 Operating Mode Dialog BoxTable 7-4 Profile ID FieldsField DescriptionName The name and (WLAN) identifier of the network connection. Enter a user friendly name for the mobile computer profile used to connect to either an AP or another networked computer. Example: The Public LAN.ESSID The ESSID is the 802.11 extended service set identifier. The ESSID is 32-character (maximum) string identifying the WLAN, and must match the AP ESSID for the EDA to communicate with the AP.NOTE Two profiles with the same user friendly name are acceptable but not recommended.PRELIMINARY10/20/06
7 - 6 MC70 Integrator GuideTap Next. If Ad-Hoc mode was selected the Ad-Hoc dialog box displays. If Infrastructure mode was selected the Authentication dialog box displays. See Authentication on page 7-7 for instruction on setting up authentication.Table 7-5 Operating Mode FieldsField DescriptionOperating Mode Select Infrastructure to enable the EDA to transmit and receive data with an AP. Infrastructure is the default mode.Select Ad Hoc to enable the EDA to form its own local network where mobile computers communicate peer-to-peer without APs using a shared ESSID.Country Country determines if the profile is valid for the country of operation. The profile country must match the country in the options page or it must match the acquired country if 802.11d is enabled.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.PRELIMINARY10/20/06

This method uses a digital certificate to verify and authenticate a user's identity.LEAP Select this option to enable LEAP authentication, which is based on mutual authentication. The AP and the connecting mobile computer require authentication before gaining access to the network.TTLS Select this option to enable TTLS authentication. Table 7-6 Authentication Options (Continued)Authentication DescriptionTable 7-7 PEAP Tunneled Authentication OptionsPEAP Tunneled Authentication DescriptionMS 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.PRELIMINARY10/20/06
Wireless Applications 7 - 9Table 7-8 lists the TTLS tunneled authentication options.User Certificate SelectionIf you checked the User Certificate check box on the Tunneled Authentication dialog box or if TLS is the selected authentication type, the Installed User Certificates dialog box displays. Select a certificate from the Table 7-8 TTLS Tunneled Authentication OptionsTTLS Tunneled Authentication DescriptionCHAP 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.PRELIMINARY10/20/06

7 - 12 MC70 Integrator GuideCredential Cache OptionsIf you selected any of the password-based authentication types, you can select different credential caching options. These options specify when the network credential prompts appear: at connection, on each resume, or at a specified time. Entering the credentials directly into the profile permanently caches the credentials. In this case, the EDA does not require user login. If a profile does not contain credentials entered through the configuration editor, you must log in to the EDA before connecting.Caching options only apply on credentials entered through the login dialog box. Figure 7-15 Prompt for Login at Dialog BoxIf the EDA does not have the credentials, you are prompted to enter a username and password. If the EDA has the credentials (previous entered via a login dialog box), it uses these credentials unless the caching options require the EDA to prompt for new credentials. If you entered the credentials via the profile, the EDA does not prompt for new credentials. Table 7-9 lists the caching options.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 following authentication types have credential caching:•EAP TLS•PEAP•LEAP•TTLS.Table 7-9 Cache OptionsDescriptionAt Connect Select this option to prompt for credentials whenever the WCS tries to connect to a new profile. Deselect this to use the cached credentials to authenticate. If the credentials are 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.PRELIMINARY10/20/06

Each communication carries the address of the source and destination networks and the particular machine within the network associated with the user or host computer at each end. This address is called the IP address (Internet Protocol address). 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 Most TCP/IP networks use subnets to manage routed IP addresses. Dividing an organization's network into subnets allows it to connect to the Internet with a single shared network address, for example, 255.255.255.0. Table 7-14 IP Config Advanced Address Entry FieldsField DescriptionG/W The default gateway forwards IP packets to and from a remote destination.DNS The Domain Name System (DNS) is a distributed Internet directory service. DNS translates domain names and IP addresses, and controls Internet email delivery. Most Internet services require DNS to operate properly. If DNS is not configured, Web sites cannot be located and/or email delivery fails.WINS WINS is a Microsoft® Net BIOS name server. WINS eliminates the broadcasts needed to resolve computer names to IP addresses by providing a cache or database of translations. PRELIMINARY10/20/06

If the IP type is DHCP, leased IP address and network address data appear for the EDA. If the IP type is Static, the values displayed were input manually in the IP Config tab on page 7-17.IP Address Displays the EDA’s IP address. The Internet is a collection of networks with users that communicate with each other. Each communication carries the address of the source and destination networks and the particular machine within the network associated with the user or host computer at each end. This address is called the IP address. 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. 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 Displays the subnet address. Most TCP/IP networks use subnets to manage routed IP addresses. Dividing an organization's network into subnets allows it to connect to the Internet with a single shared network address, for example, 255.255.255.0.Gateway Displays the gateway address. A gateway forwards IP packets to and from a remote destination.DCHP Server The Domain Name System (DNS) is a distributed Internet directory service. DNS translates domain names and IP addresses, and controls Internet e-mail delivery. Most Internet services require DNS to operate properly.
