6.1 Installing The 802.11b Radio

The WORKABOUT PRO operates with an 802.11b Direct Sequence Spread

Spectrum radio. The CF (Compact Flash) card is easily installed in the unit.

• To begin, remove the battery pack. If your unit is using AC power, disconnect it.

• Remove the stylus from the end-cap before removing the end-cap itself.

• Remove the end-cap at the top of the WORKABOUT PRO – unscrew the four Philips head screws from the cap.

6.2 Connecting To A LAN Using An 802.11b Radio

Once the 802.11b radio is installed in the WORKABOUT PRO, you’ll need to take a few steps to configure the radio.

6.2.1 Configuring An IEEE 802.11b Radio

While most common 802.11b settings are configured as defaults, there are some fields that must be completed, including the SSID of your access point and the security methods implemented in the network (including access keys).

Psion Teklogix WORKABOUT PRO Hand-Held Computer User Manual 111

Chapter 6: Connecting To A LAN With 802.11b

Configuring An IEEE 802.11b Radio

Important: If the WORKABOUT PRO radio has never been configured, the radio settings dialogue box will open automatically when the unit is powered on. In this case, skip to Step 4 on page 113.

To configure the 802.11b radio:

1. Tap on the Start button in the taskbar, and tap on

Settings>

Network....

Figure 6.5 Network And Dial-Up Connections

Note: You can also press <CTRL> <ESC> to display the Start Menu.

2. Tap on the radio icon to open the 802.11b Wireless LAN Settings window – in the sample screen this is labelled NETWLAN1 .

Wireless Information Tab

The options under this tab list existing networks to which you can connect, and it allows you to add a new network or modify the settings for an existing network.

Note: <Configure> button – To change the settings in an existing network, highlight the network you want to modify, and tap the < Configure> button to display the Wireless Properties dialogue box.

<Connect> button – To force connection to a specific, existing network, highlight the network to which you want your unit to connect, and tap the < Connect> button.

This tab lists available networks – any access points that are broadcasting an SSID, and it lists preferred networks – networks that you have configured. Since access points are generally secure, they will most likely not be listed here. By default, the unit attempts to connect to preferred networks. This behaviour can be changed by enabling (

√

) ‘Automatically connect to non-preferred networks’ in the Advanced dialogue box (page 118).

• To add a new configuration, tap the < Add New> button. A blank Wireless

Properties dialogue box is displayed.

The Network name field can contain a maximum of 32 characters. The name assigned here is listed as a preferred network.

Important: Keep in mind that the WORKABOUT PRO will only communicate with access points that are configured with the same SSID.

Ad Hoc And Infrastructure

If you are using an “Infrastructure” network – one in which WORK-

ABOUT PROs must pass data through an access point – leave the checkbox next to ‘This is an ad hoc network’ blank.

If you are using an “Ad Hoc” network – a network in which hand-held computers pass data directly to other hand-helds without an access point – tap on the checkbox next to ‘This is an ad hoc network’ to enable (

√

) Ad Hoc.

Encryption

WEP (Wired-Equivalent Privacy) encryption prevents others from accidentally accessing your network. If you are not using encryption, you can choose ‘Disabled’ from the dropdown encryption menu. Otherwise, leave this field as is.

Authentication

802.11b supports two subtypes of network authentication services: Open and Shared . Under Open authentication, any wireless station can request authentication. The station that needs to authenticate with another wireless station sends an authentication management frame that contains the identity of the sending station. The receiving station then sends back a frame that indicates whether it recognizes the identity of the sending station.

Under Shared authentication, each wireless station is assumed to have received a secret shared key over a secure channel that is independent from the 802.11b wireless network communications channel.

Network Key:

This text box is used to specify a 5 or 13 ASCII character sequence or an equivalent 10 or 26 Hexadecimal digit sequence that matches the active

WEP key on the access point.

Psion Teklogix WORKABOUT PRO Hand-Held Computer User Manual 115

Key Index:

This field is used to identify the WEP key.

• Enter a value from 1 to 4.

Enable 802.1x authentication

“802.1X” is the IEEE standard that offers additional security for local area networks. It provides authentication for user devices attached to an Ethernet network, whether wired or wireless. A security protocol packet such as TLS or MD5 encapsulated in an “EAP” is used in conjunction with the “802.1x” standard to authenticate users at the MAC layer. Available EAPs are listed in the dropdown menu next to the ‘EAP’ option.

• To activate “802.1X”, tap the stylus in the checkbox next to ‘Enable 802.1x authentication’ to enable (

√

) it.

EAP Type (Extensible Authentication Protocol):

This dropdown menu lists the EAP types available on your system. The items in this dropdown menu will vary depending on your network setup.

Keep in mind also that some authentication protocols require that you select a ‘Certificate’. By selecting the Properties button, you will be able to select a

Certificate. “Certificate Assignment” on page 77 provides a website that outlines how to create certificates for your network.

6. Saving and exiting the radio setup.

Once you have completed your configuration, tap on < OK> .

Chapter 6: Connecting To A LAN With 802.11b

Assigning An IP Address

The connection you created will be listed in the Wireless Information tab as a preferred network. The radio will search for the SSID and will compare the WEP and authentication information you specified. If there is a match between your

WORKABOUT PRO settings and the access point settings, the WORKABOUT

PRO will communicate on the network through the access point.

6.2.2 Assigning An IP Address

If your network is not using a DHCP server, you will need to assign an IP address.

• In the NETWLAN1 Settings window, display the IP Information tab.

Figure 6.11 IP Information

Note: Tapping on the <Renew> button forces the WORKABOUT PRO to renew or find a new IP address. This is useful if, for example, you are out of communication range for a longer period of time and your hand-held is dropped from the network.

• Tap on the <Configure...> button to define a static IP address.
